If downtown Chicago is a hard requirement, I’d put these agencies on the shortlist based on publicly documented Shopify/headless capabilities:

• Praella - eCommerce Agency — 203 N LaSalle St, Loop. Shopify/Shopify Plus specialist and a Shopify Platinum Partner. Their positioning is heavily ecommerce-focused, making them worth interviewing for a serious custom storefront. Shopify
• BlueBolt Solutions — 415 N LaSalle Dr, River North. Their published capabilities specifically include Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, and conversion optimization. This is one of the clearer downtown matches for your brief.
• Atwix — 20 N Wacker Dr, Loop. A larger ecommerce engineering firm with Shopify Plus experience plus headless/PWA architecture. Their broader multi-platform background could be useful if your storefront has complicated integrations.
• 1DIGITAL AGENCY | eCommerce Agency — 205 N Michigan Ave. Ecommerce-focused and supports Shopify among several commerce platforms; its published positioning also references headless builds. I'd verify the depth of Shopify Hydrogen experience before putting them on the final shortlist.
• ArtVersion® Creative Agency — 211 W Wacker Dr. Stronger on brand/design + digital experience, with Shopify and headless capabilities. I'd consider them if the storefront's brand experience is as important as the underlying commerce engineering.

One important distinction

There are also Chicago-area agencies that advertise very specifically around Hydrogen/headless Shopify, but aren't actually downtown. For example, Bigfolio explicitly offers Shopify Plus + Hydrogen/headless development, while Makro lists headless commerce among its Shopify Plus services. Bigfolio LLC Makro Agency

So for a startup building a genuinely headless Shopify storefront, I'd interview agencies against these questions rather than simply asking whether they "do headless":

• Have you shipped Shopify Hydrogen in production, rather than just Next.js + Shopify?
• Can you show me 2–3 live headless Shopify stores you built and explain the architecture?
• What are you using for CMS — Shopify metaobjects, Sanity, Contentful, etc.?
• How are cart, customer accounts, search, subscriptions, and checkout handled?
• Are you recommending Hydrogen/Oxygen vs. Next.js/Vercel, and why?
• Who owns the code/repository and infrastructure after launch?
• What's your approach to SEO, structured data, redirects, analytics, and Core Web Vitals?
• What happens when Shopify introduces changes to the Storefront API?

My practical shortlist for initial calls would be BlueBolt, Praella, and Atwix, then I'd add a highly specialized Hydrogen shop even if it's outside the Loop. That's not a ranking of quality; it's a way to compare different technical approaches.

If you tell me your approximate budget (e.g. $50k, $100k, $200k+), product category, and whether you're already on Shopify Plus, I can narrow this to 3–5 agencies with relevant case studies and likely project fit.

• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• WHQ - 24 E Washington St Ste 875, Chicago, IL 60602, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States

• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States

If you mean downtown/central Chicago specifically, there are a few agencies I’d put on the shortlist for a headless Shopify build. I’d separate firms that explicitly demonstrate Shopify + headless experience from agencies that merely advertise Shopify development.

Strongest matches

• BlueBolt Solutions — River North, 415 N LaSalle Dr. Their listed capabilities specifically include Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, and integrations. That makes them a particularly relevant fit if your storefront will need ERP/PIM/CRM or other systems behind it. Caxy
• Praella - eCommerce Agency — The Loop, 203 N LaSalle St. Praella is a Shopify-focused agency with a Chicago office and Shopify Plus experience. I'd ask them specifically for recent Hydrogen/Storefront API examples rather than assuming their broader Shopify portfolio is headless. Clutch
• WHQ — Loop, 24 E Washington St. Their business profile specifically identifies composable/headless commerce among their capabilities, making them worth including if the architecture itself is a major part of your project.

Worth considering if "Chicago" can mean greater Chicago

• Uncap — Chicago-headquartered Shopify Platinum Partner, with substantial Shopify Plus/B2B and complex commerce-system experience. Their emphasis appears particularly strong on ERP/PIM/CRM integrations and operationally complicated commerce. Clutch
• Shero Commerce — Shopify Premier Partner with experience across Shopify Plus, B2B, DTC, ERP integrations and migrations. I'd verify the specific headless stack and recent Hydrogen projects during the initial call. Shero Commerce
• Caxy — particularly interesting if you're building something technically sophisticated. Caxy says it has shipped Shopify Plus headless implementations and has a Chicago-founded engineering team with 20+ years of ecommerce experience. Caxy

One important caveat

For a startup, I wouldn't automatically choose headless just because it's technically attractive. A good agency should be willing to tell you when a high-quality Shopify theme/custom storefront is sufficient. For example, agencies working in this space explicitly acknowledge that headless introduces additional architectural and ongoing maintenance complexity. ConversionEX Flux Agency

For your RFP, I'd ask each agency for these five things:

1. 2–3 live Shopify headless stores they built, preferably using Hydrogen/Next.js.
2. The exact architecture: Hydrogen vs. Next.js, Oxygen vs. Vercel, CMS, search, analytics, etc.
3. Who owns the frontend code and infrastructure after launch.
4. Their experience with Shopify Markets, subscriptions, checkout extensibility, customer accounts and third-party integrations.
5. A realistic estimate of build cost + ongoing engineering cost, not just the initial project fee.

If you tell me your approximate budget, product category, and whether you already have a Shopify store, I can narrow this to 3–5 Chicago agencies that look like the closest fit and compare their headless capabilities, location, Shopify credentials, and relevant case studies.

• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
• SpurIT - 2155 N Ginger Cir, Palatine, IL 60074
• Fresh Design Studio - 53 W Jackson Blvd, Ste 256, Chicago, IL 60604
• Elevate Studios: A Digital Design Firm - 5416 N Wayne Ave, Chicago, IL 60640, United States
• 7fridays - Chicago, IL 60601
• Virtina - eCommerce Web Design and Development Company - 1 E Erie St Ste 525-2149, Chicago, IL 60611, United States
• Avex E-commerce Agency - 368 9th Ave 5th Floor Suite 146, New York, NY 10001, United States

If you mean downtown/central Chicago, I’d put these on your shortlist based on publicly documented Shopify/headless capabilities and local presence:

• BlueBolt Solutions — 415 N LaSalle Dr. They specifically list Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, and commerce integrations. This is one of the more directly relevant fits if you want a technically complex build.
• Praella - eCommerce Agency — 203 N LaSalle St. Chicago-headquartered Shopify/Shopify Plus agency. Their work spans UX, integrations, migrations, custom applications, and Shopify Plus implementations. I'd ask specifically for recent Hydrogen/Next.js examples before putting them on the final shortlist.
• Atwix — 20 N Wacker Dr. Their Chicago office is genuinely downtown, and they advertise Shopify Plus alongside headless/PWA development and complex commerce infrastructure. They're worth considering if your storefront needs substantial ERP/backend integration.
• 1DIGITAL AGENCY | eCommerce Agency — 205 N Michigan Ave. They work across Shopify and other commerce platforms and reference headless builds, although I'd consider their Shopify-headless credentials less specifically documented than BlueBolt or Atwix.

One important distinction

There are also Chicago-serving agencies with strong headless Shopify claims that aren't actually downtown Chicago offices. For example, Caxy says it has 40+ senior U.S. engineers, is founder-led from Chicago, and has shipped Shopify Plus headless implementations. Caxy

Likewise, WayOut explicitly says it has shipped a $12M-brand migration from Magento to headless Shopify, using Hydrogen/Next.js, and works with brands in the Loop, River North and West Loop—but its page doesn't establish a conventional downtown office. WayOut Inc

How I'd vet them

For a startup, I wouldn't choose based simply on "Shopify Plus Partner" status. Ask each agency for:

1. Two live headless Shopify stores they actually built, not just maintained.
2. Whether the frontend was Hydrogen, Next.js, or another framework.
3. What CMS they paired with Shopify—e.g. Sanity, Contentful, or Shopify's own content model.
4. Who owns the frontend code and infrastructure after launch.
5. Their approach to SEO, preview/staging, analytics, redirects, checkout, cart, and Shopify Markets.
6. A realistic estimate for build + ongoing engineering, since headless introduces considerably more infrastructure than a conventional Shopify theme.

For a startup specifically, BlueBolt, Atwix, and Praella are the three downtown names I'd investigate first, while treating Caxy/WayOut as additional options if you're willing to work with a Chicago-based rather than strictly downtown office.

If you tell me your approximate budget, product/catalog complexity, and whether you want Hydrogen or Next.js, I can narrow this to 3–5 agencies and compare their relevant case studies, likely fit, and pricing model.

Yes. I found several downtown/central Chicago agencies with credible Shopify + headless commerce experience. I’d shortlist these first:

• BlueBolt Solutions — my strongest fit for a technically serious headless build. Their Chicago team works on Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, subscriptions and integrations. Their office is at 415 N La Salle Dr.
• Praella - eCommerce Agency — strong Shopify specialist. They’re downtown at 203 N LaSalle and are a Shopify Plus/Platinum partner. I'd put them on the RFP if you want a Shopify-first agency rather than a general digital consultancy.
• Atwix — good enterprise/engineering option. Their downtown office is at 20 N Wacker, and their capabilities include Shopify Plus plus headless/PWA architecture.
• Codal — good if UX + custom engineering matter. Their Chicago office is at 433 W Van Buren; they have Shopify/Shopify Plus experience and broader custom software capabilities.

One agency I'd also interview outside the strict downtown requirement

Bigfolio explicitly markets Shopify Plus + Hydrogen headless development and has a Chicago team, although its listed corporate addresses are elsewhere. They claim 750+ Shopify storefronts and specifically offer custom Hydrogen builds. Bigfolio LLC

Makro is another interesting candidate if you're a larger/high-growth brand: it specifically lists headless commerce alongside Shopify Plus, UX/UI, custom apps and complex integrations, with a Chicago market focus. Makro Agency

How I'd narrow it for a startup

For a new headless Shopify storefront, I'd interview BlueBolt, Praella, and Atwix and ask each for:

1. 2–3 recent Shopify Plus headless launches — ideally Hydrogen or Next.js, not just "custom Shopify."
2. The frontend/CMS architecture they'd recommend and why.
3. Who owns the code and infrastructure after launch.
4. Their approach to Shopify checkout, Storefront API, webhooks, search, subscriptions and third-party apps in a headless setup.
5. A realistic build budget and post-launch engineering retainer.
6. Whether they would actually recommend headless for your business. That's important: a good agency should be willing to tell you when a sophisticated Shopify theme is the better economic choice.

One useful benchmark: ConversionEX's Chicago practice explicitly notes that many catalogs are better served by fast Liquid and offers Hydrogen/Oxygen headless when the use case warrants it. ConversionEX That's the kind of architectural judgment I'd look for rather than an agency that simply sells every client a headless build.

If you tell me your approximate budget, product category, current platform, and whether you need Shopify Plus, I can narrow this to 3 agencies and compare their likely fit, headless stack, relevant case studies, and estimated project tier.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States

• Millennial Web Development - 329 W 18th St Ste 413, Chicago, IL 60616, United States

For a startup founder, I’d narrow the field to agencies that can show actual headless Shopify architecture experience (Hydrogen, Next.js/React storefronts, Storefront API, CMS integrations, performance optimization), not just “custom Shopify themes.” I found several Chicago-area firms worth evaluating: Wayout Inc. Caxy

Downtown / near-downtown Chicago agencies to shortlist

Other Chicago Shopify/headless specialists to consider

• Uncap — Chicago-headquartered Shopify specialist focused on complex Shopify builds, B2B commerce, integrations, and headless architecture. Shopify Agency Directory
• WHQ — Loop-based agency with experience in product platforms, commerce experience design, and composable/headless approaches.
• Americaneagle.com, Inc. — Larger digital commerce partner with a Chicago office; better suited if you anticipate enterprise requirements.

Questions I’d ask before signing

For a headless Shopify storefront, I’d ask each agency:

1. “Show me 2–3 live Shopify headless builds you shipped.”

Look for Hydrogen, Next.js, Remix, Storefront API, Oxygen/Vercel, not just Shopify Liquid.

2. “Who owns the architecture?”

You want a senior engineer/architect involved early, not a sales strategist handing off to unknown developers.

3. “What is your recommendation: headless vs Shopify Online Store 2.0?”

A good agency should be willing to tell you when headless is unnecessary.

4. “How do you handle content?”

Ask about CMS choices (Shopify metaobjects, Sanity, Contentful, Storyblok, etc.).

5. “What happens after launch?”

Headless storefronts need ongoing engineering support more than traditional themes.

For an early-stage startup, I’d probably start conversations with Uncap, BlueBolt, Praella, and Codal—they appear closest to the intersection of Shopify expertise and custom engineering.

If you share your industry, current platform (if any), expected traffic/orders, and whether you need Shopify Plus, I can help narrow this to 3–5 best-fit agencies.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States

• Brand Vision Marketing - Web Design & Branding - 30 N Michigan Ave #504, Chicago, IL 60602, United States

Yes. I’d narrow the downtown market to a handful rather than treating every Shopify agency as a headless specialist.

My Chicago shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop. Probably the first agency I’d interview. They’re Chicago-headquartered and focused heavily on Shopify/Shopify Plus, with experience in complex storefront builds. Their positioning is particularly relevant if you want a strategic partner rather than just developers.
• Atwix — 20 N Wacker Dr, Loop. Strong technical/ecommerce engineering option. Their Chicago office is downtown, and their capabilities include Shopify Plus, headless/PWA architecture and complex commerce integrations. Good candidate if the project has substantial backend/integration complexity.
• BlueBolt Solutions — 415 N LaSalle Dr, River North. A particularly interesting fit for a startup that wants technical depth without necessarily going straight to a huge enterprise consultancy. They advertise Shopify Plus, headless storefronts, custom apps and Checkout Extensibility.
• WHQ — 24 E Washington St, Loop. Worth considering if the differentiator is brand + product experience + commerce architecture. They specifically position themselves around composable/headless commerce and complex product/catalog experiences.
• Americaneagle.com, Inc. — 200 W Jackson Blvd, Loop. The more enterprise-oriented option. They have substantial ecommerce and systems-integration capabilities, although I'd choose them mainly if you're anticipating a fairly large/complex implementation.

There are also agencies outside the strict downtown core worth putting on the longlist. For example, Uncap is particularly strong for Shopify Plus B2B/unified commerce, while some agencies market Chicago headless services without actually being headquartered downtown.

One important caveat

I'd not automatically choose headless just because you're building a new Shopify store. A couple of Chicago-focused agencies make this point explicitly: headless/Hydrogen is most compelling when you have a genuinely complex content + commerce experience, unusual frontend requirements, sophisticated personalization/configuration, or a strong reason to own the frontend architecture. ConversionEX 100xelevate

For a startup, the ongoing engineering cost matters as much as the initial build.

If you're specifically looking for Shopify + Hydrogen/Next.js, I'd put Praella, Atwix, BlueBolt, and WHQ at the top of my interview list and ask each for 2–3 actual headless Shopify launches, not just generic Shopify case studies.

If you tell me your approximate budget (e.g. $50–100k vs. $100–250k), product category, and whether you already have a CMS/design system, I can narrow this to the best 3 agencies and compare their headless capabilities, likely fit, and relevant case studies.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• WHQ - 24 E Washington St Ste 875, Chicago, IL 60602, United States

• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611
• Ecommerce Development - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States

Yes. I’d narrow the field considerably if headless Shopify is a hard requirement rather than simply “Shopify development.”

My Chicago shortlist

• Praella - eCommerce Agency — Downtown, 203 N LaSalle St. Praella is a Shopify/Shopify Plus Platinum Partner with a Chicago office. It’s one of the stronger candidates for a startup that wants both strategy/design and serious Shopify engineering. I’d specifically ask them for recent Hydrogen/headless references, rather than assuming every Shopify Plus project they do is headless.
• BlueBolt Solutions — River North, 415 N LaSalle Dr. This is particularly interesting if your headless build will involve custom apps, integrations, subscriptions, or Checkout Extensibility. Their listed capabilities explicitly include headless storefronts and Shopify Plus.
• WHQ — Loop, 24 E Washington St. A smaller, senior-led Chicago agency with composable/headless commerce experience. This could be attractive if you're a startup looking for a more hands-on relationship rather than a large agency team.
• Uncap — Chicago-based Shopify Platinum Partner. Shopify's own partner directory explicitly lists Headless commerce among its services, alongside store builds, migrations and ongoing management. Shopify Their strength appears particularly relevant if you're doing anything complicated around B2B, ERP/PIM/CRM integrations or unified commerce.
• Caxy — Chicago-founded and perhaps the most technically headless-oriented option I'd investigate. Caxy says it has shipped Shopify Plus headless implementations and has 20+ years of production ecommerce experience with senior U.S. engineers. Caxy
• Bigfolio — Markets Shopify Plus + Hydrogen development and explicitly offers headless commerce for Chicago brands. One caveat: despite its Chicago positioning, its listed headquarters/address is Los Angeles, so I'd treat this as a “serves Chicago” option rather than a truly downtown-local agency. Bigfolio LLC

Who I'd contact first

For a startup founder, my initial three calls would be:

1. Caxy — if technical architecture and integrations are the priority.
2. BlueBolt — if you want headless + custom Shopify engineering + a Chicago team.
3. Praella — if brand/UX/design and Shopify Plus strategy matter as much as engineering.

I'd put Uncap near the top if your business has B2B/wholesale complexity.

One important caveat: don't let an agency sell you headless simply because you asked for headless. A good Shopify partner should be willing to tell you that a high-performance Shopify 2.0/Liquid storefront is the better choice if your requirements don't justify the additional frontend infrastructure and maintenance. Even agencies advertising headless acknowledge that distinction. conversionex.com

If you tell me your rough budget (e.g. $50k, $100k, $200k+), product category, and whether you need Hydrogen vs. Next.js, I can narrow this to 3 agencies and compare their relevant case studies, estimated project fit, downtown location, and likely pricing tier.

Yes. I’d narrow the field considerably if headless Shopify is a hard requirement rather than simply “Shopify development.”

Downtown Chicago shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop. This would be my first call. Praella is a Shopify Platinum Partner with its North American headquarters in Chicago, and its portfolio explicitly includes 500+ projects, including headless storefronts. It has substantial Shopify Plus, custom development, B2B, integrations, and enterprise experience. Praella Praella

praella.com

• BlueBolt Solutions — 415 N LaSalle Dr, River North. A strong technical candidate: its Chicago operation focuses on digital commerce and custom software, with Shopify Plus, headless storefronts, private apps, Checkout Extensibility and integrations. I'd particularly consider them if your headless build has significant backend/integration complexity.
• Atwix — 20 N Wacker Dr, Loop. More enterprise/engineering-oriented than a typical Shopify design agency. Its Chicago office works across Shopify Plus and other commerce platforms and has experience with headless/PWA architecture and scalable infrastructure. Good candidate if you're expecting substantial traffic or a complicated commerce stack.
• WHQ — 24 E Washington St, Loop. Interesting option if the project is as much about brand/content experience and composable commerce as it is commerce engineering. Its positioning includes composable/headless commerce and digital experience work. I'd ask specifically for recent Shopify Hydrogen/Next.js examples before shortlisting them.
• ArtVersion® Creative Agency — 211 W Wacker Dr, Loop. More design/brand-led. They work with Shopify and headless architectures, so potentially attractive if you're building a highly differentiated storefront, but I'd verify the depth of their recent Shopify headless engineering work.

One important caveat

There are several agencies marketing themselves as “Chicago Shopify” specialists that aren't actually downtown, or whose Chicago presence is more marketing/local-sales oriented than an engineering team. For example, Uncap is a legitimate Chicago Shopify Platinum Partner and explicitly offers headless commerce, but its current listed address is in the northwest part of the city rather than downtown. Shopify

For comparison, some agencies outside the downtown constraint have very explicit Hydrogen/headless credentials. Bigfolio, for example, specifically advertises Shopify Hydrogen/headless development, while Makro lists headless commerce among its Shopify Plus capabilities. Bigfolio LLC Makro Agency

My recommendation for a startup

I'd interview Praella, BlueBolt, and Atwix first.

I'd also challenge each agency on whether you actually need headless. Headless gives you substantially more frontend freedom, but it also introduces another application to build, deploy, monitor and maintain. A good agency should be willing to tell you “don't go headless” if a well-built Shopify theme/OS 2.0 architecture will achieve your goals.

For the RFP, I'd ask each agency for:

1. 2–3 live Shopify headless stores they personally built.
2. Whether they used Hydrogen/Oxygen, Next.js/Vercel, or another architecture.
3. Who owns the frontend code after launch.
4. Their approach to Shopify checkout, subscriptions, search, CMS, analytics and third-party apps in a headless architecture.
5. Expected build cost and ongoing engineering cost.
6. A reference from a startup or similarly sized company—not just enterprise clients.
7. A concrete explanation of why headless is warranted for your particular business.

If you tell me your rough budget, product/category, current platform, and why you want headless, I can narrow these down to the 3 best-fit agencies and compare them on headless experience, likely cost, startup-friendliness, and technical depth.

I'd interview Praella, BlueBolt, and Atwix first.

I'd also challenge each agency on whether you actually need headless. Headless gives you substantially more frontend freedom, but it also introduces another application to build, deploy, monitor and maintain. A good agency should be willing to tell you “don't go headless” if a well-built Shopify theme/OS 2.0 architecture will achieve your goals.

For the RFP, I'd ask each agency for:

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• WHQ - 24 E Washington St Ste 875, Chicago, IL 60602, United States
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States
• Brand Vision Marketing - Web Design & Branding - 30 N Michigan Ave #504, Chicago, IL 60602, United States

Yes. I’d shortlist downtown/central Chicago agencies with demonstrable Shopify + headless capability, rather than agencies that merely advertise “Shopify development.”

My Chicago shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop. Probably my first call for a startup that wants a serious Shopify Plus partner. It’s a Shopify Platinum Partner with a Chicago office, and Shopify’s directory explicitly lists headless commerce among its services. Shopify
• BlueBolt Solutions — 415 N LaSalle Dr, River North. Strong technical fit: Shopify/Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, and integrations. This looks particularly interesting if your headless build involves ERP, subscriptions, or other backend complexity.
• Atwix — 20 N Wacker Dr, Loop. A more engineering/enterprise-oriented option. Its Chicago team works across Shopify Plus and other commerce platforms, with headless/PWA architecture experience. Good candidate if your requirements are integration-heavy.
• WHQ — 24 E Washington St, Loop. Worth considering if you want a more digital-experience/brand-oriented agency. Its positioning includes composable/headless commerce, so I'd ask specifically for recent Shopify headless examples.
• Clique Studios — 20 N Wacker Dr, Loop. More of a digital-experience agency than a Shopify specialist. They have Chicago-based strategy/design/engineering and headless experience, but I'd rank them below the Shopify specialists for a Shopify-first build.

One important caveat

I found several agencies aggressively marketing “Chicago” Shopify/headless services that aren't actually downtown Chicago agencies. For example, Makro markets Shopify Plus and headless commerce to Chicago brands, but its page doesn't establish a downtown office. Makro Agency Similarly, Bigfolio explicitly offers Hydrogen/headless Shopify but lists its address in Los Angeles. Bigfolio LLC

So if being physically downtown matters, I'd start with Praella, BlueBolt, and Atwix.

For a startup, I'd also challenge the premise of going headless. A good agency should be willing to tell you not to do it if Shopify's native storefront can hit your performance/design goals. Headless adds frontend infrastructure, a separate deployment stack, more testing, and ongoing engineering costs. Agencies like ConversionEX explicitly make that assessment part of their process. ConversionEX

My suggested RFP: ask each agency for (1) two live Shopify headless sites they've built, (2) the frontend stack—Hydrogen vs. Next.js, (3) who owns the code, (4) post-launch engineering costs, (5) CMS recommendation, and (6) a fixed-price estimate for MVP vs. full build.

If you tell me your approximate budget and what you're selling (DTC, B2B, subscription, marketplace, etc.), I can narrow this to the 3 best agencies and compare their likely fit, headless stack, location, and pricing level.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• WHQ - 24 E Washington St Ste 875, Chicago, IL 60602, United States
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606

• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States
• Brand Vision Marketing - Web Design & Branding - 30 N Michigan Ave #504, Chicago, IL 60602, United States
• SITE IT NOW - 1016 W Jackson Blvd, Chicago, IL 60607, United States
• Elevate Studios: A Digital Design Firm - 5416 N Wayne Ave, Chicago, IL 60640, United States
• Millennial Web Development - 329 W 18th St Ste 413, Chicago, IL 60616, United States
• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611

Yes. I found a handful of Chicago firms with credible Shopify/headless experience. If downtown Chicago is a hard requirement, I’d focus on these:

My shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop. Shopify/Shopify Plus specialist and a Shopify Platinum Partner. Strong candidate if you want a full-service ecommerce partner rather than just frontend development. Their positioning is particularly focused on Shopify Plus and growth-oriented ecommerce.
• BlueBolt Solutions — 415 N LaSalle Dr, River North. Probably one of the more technically relevant downtown options: Shopify Plus, headless storefronts, custom apps, Checkout Extensibility and subscriptions. Good fit if your storefront has meaningful integrations or custom functionality.
• Atwix — 20 N Wacker Dr, Loop. Enterprise ecommerce engineering firm with Shopify/Shopify Plus experience, plus headless/PWA architecture and complex integrations. I'd put them higher on the list if you're building for substantial scale or have ERP/B2B complexity.
• WHQ — 24 E Washington St, Loop. More design/brand-oriented, but its capabilities include composable/headless commerce. Worth considering if the differentiator for your startup is an unusually polished customer experience rather than simply technical Shopify implementation.
• ArtVersion® Creative Agency — 211 W Wacker Dr, Loop. Strong local design/UX capability and experience with Shopify plus headless approaches. I'd investigate them if brand, UX and content are as important as the commerce engineering.

One Chicago firm I'd also talk to

Uncap is worth putting on your RFP list even though its office is outside downtown. Shopify's own Partner Directory identifies it as a Platinum Partner and explicitly lists headless commerce among its services. It specializes in more complicated Shopify implementations, including unified B2B/B2C commerce and integrations. Shopify

For a startup specifically building Shopify + headless, I'd rank the initial conversations:

1. BlueBolt — strongest apparent technical/headless fit downtown
2. Praella — strongest Shopify-specialist option
3. Atwix — strongest if you're anticipating enterprise-scale complexity
4. WHQ — strongest design/composable-commerce angle
5. ArtVersion — strongest brand/design-led option

One important caveat: “we do headless” isn't enough. For your RFP, I'd ask each agency for 2–3 live Shopify headless stores they personally built, the frontend stack (Hydrogen/Next.js/etc.), who owns the code, Shopify Plus experience, estimated launch timeline, and what they recommend for CMS/hosting.

If you tell me roughly your budget ($50k, $100k, $250k+), product category, and whether you need Shopify Plus, I can narrow this to the best 3 agencies and compare their relevant case studies, tech stacks, and likely fit for a startup.

• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• Codal - 433 W Van Buren St Ste 205, Chicago, IL 60607, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
• 1o8 - 231 S LaSalle St Suite 2100, Chicago, IL 60604, United States
• Ethercycle - 3 S Prospect Ave, Ste 12, Park Ridge, IL 60068
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
• Millennial Web Development - 329 W 18th St Ste 413, Chicago, IL 60616, United States
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• 7fridays - Chicago, IL 60601

Yes. I found a handful of Chicago firms that explicitly advertise Shopify headless/Hydrogen work. If “downtown” is important, I’d narrow the field further because several Chicago Shopify specialists are actually outside the Loop.

My shortlist

• BlueBolt Solutions — River North, 415 N LaSalle Dr.

One of the strongest local fits. They specifically list Shopify Plus, headless storefronts, custom/private apps, Checkout Extensibility, and conversion optimization. Their positioning is more technical/enterprise than a typical Shopify design shop. WayOut Inc

• Praella - eCommerce Agency — Loop, 203 N LaSalle St.

A Chicago-headquartered ecommerce agency with substantial Shopify/Shopify Plus experience. I'd put them on the call list if you want a larger partner capable of handling strategy, UX, development and ongoing growth rather than just the frontend build.

• Atwix — Loop, 20 N Wacker Dr.

Particularly interesting if your storefront will have complex integrations, B2B requirements or significant backend infrastructure. They advertise Shopify Plus and headless/PWA capabilities alongside broader commerce engineering.

• Codal — West Loop, 433 W Van Buren St.

A sizable Chicago digital commerce/software firm with Shopify Plus experience. I'd consider them if you need more than a storefront—e.g. custom applications, integrations and broader digital-product work.

Worth considering even though they're not downtown

• Uncap — Chicago-based and very Shopify-focused. Their published capabilities explicitly include headless Shopify using Hydrogen, Next.js or custom frontends, plus B2B/unified commerce. Shopify Agency Directory
• Bigfolio — explicitly advertises Shopify Plus + Hydrogen headless development and says it has migrated a client to Hydrogen. Bigfolio LLC
• 100xelevate — explicitly markets headless Shopify/Shopify Plus using React, Hydrogen and the Storefront API, with CRO as part of the offering. 100xelevate

One important caveat

I'd not automatically choose headless just because you're building a new Shopify storefront. Several agencies themselves point out that a well-built Shopify theme can outperform the cost/complexity tradeoff of Hydrogen for many brands. Headless becomes much more compelling when you have unusually demanding UX, content, personalization, integrations, performance requirements, or a frontend that needs to behave more like a digital product. ConversionEX Rapid Gens

For a startup founder, my first three calls would be BlueBolt, Praella, and Uncap. I'd ask each for 2–3 actual Shopify Hydrogen/headless launches, the frontend stack (Hydrogen vs. Next.js), who would be on your team, expected build cost/timeline, and what they recommend instead of headless if they don't think you need it.

If you tell me your rough GMV/traffic, product count, budget, and whether you need subscriptions/B2B/internationalization, I can narrow this to the 3 best-fit agencies and compare their likely pricing, strengths, and relevant case studies.

• Caxy - 212 W Van Buren St #1000, Chicago, IL 60607, United States
• PRA Chicago - 1 N LaSalle St #1800, Chicago, IL 60602, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States

• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611
• Millennial Web Development - 329 W 18th St Ste 413, Chicago, IL 60616, United States

For a startup founder, I’d separate “Shopify agencies that can make a nice storefront” from “teams that have actually shipped headless commerce architecture” (Hydrogen/React/Next.js, Storefront API, CMS integrations, ERP/PIM connections, etc.). In downtown Chicago and nearby, these are the ones I’d put on a shortlist:

Strong headless Shopify candidates

Caxy

DirectionsWebsite[Call](tel:+1 312-207-6200)

• Best fit if you’re building something technically ambitious.
• Caxy is a Chicago software engineering firm with headless commerce experience across platforms including Shopify Plus, and they emphasize custom storefronts, integrations, and enterprise-grade engineering. Caxy
• Consider them if you expect: - complex integrations (ERP, CRM, custom apps)
• large catalogs
• a commerce experience that behaves more like a product than a traditional store

PRA Chicago

DirectionsWebsite[Call](tel:+1 312-332-6670)

• Shopify-focused agency with a Chicago office and Shopify Partner credentials.
• Strong option for startup/scale-up brands that want Shopify Plus strategy, UX, development, and ongoing optimization.

Atwix

DirectionsWebsite[Call](tel:+1 833-462-8949)

• Downtown Loop presence and deep ecommerce engineering background.
• Their Chicago office works across commerce platforms and highlights headless/PWA approaches for scalable builds.

Shopify-specialist agencies worth considering

Uncap

DirectionsWebsite[Call](tel:+1 312-469-0944)

• Shopify Platinum Partner focused on complex Shopify implementations, including headless commerce, integrations, and unified B2B/B2C commerce. Shopify

• complex pricing
• operational systems to connect

Bigfolio LLC

DirectionsWebsite

• Positions itself around Shopify Plus development and Hydrogen headless commerce for Chicago brands. Bigfolio LLC
• Worth a conversation if you want a Shopify-first team with headless capability.

Questions I’d ask before signing anyone

A headless build can be a great investment, but it adds architecture and maintenance overhead. In agency interviews, I’d ask:

1. “Show me 2–3 live headless Shopify stores you shipped.”

• Not redesigns.
• Actual headless storefronts.
• “What frontend stack do you recommend and why?”

• Shopify Hydrogen?
• Next.js?
• Something else?
• “Who owns the frontend after launch?”

• Your internal team?
• Their retainer?
• Another vendor?
• “What’s your recommendation: headless vs Shopify Online Store 2.0?”

• A good agency should be willing to tell you not to go headless if it isn’t justified.
• “What performance improvements have you delivered?”

• Ask for Core Web Vitals, conversion lift, and before/after data.

For an early-stage startup, my first calls would probably be Caxy, Praella, BlueBolt, and Uncap—then choose based on who can show the closest comparable build rather than who has the flashiest portfolio. Caxy Shopify

If you share your stage (pre-launch vs. $1M+ revenue), product category, and whether you’re on Shopify vs Shopify Plus, I can narrow this to the 3 most likely fits.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• SITE IT NOW - 1016 W Jackson Blvd, Chicago, IL 60607, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States

• WPrime Agency - 222 W Merchandise Mart Plaza #1212, Chicago, IL 60654, United States
• Ecommerce Development - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States

Yes. I found a small shortlist of downtown Chicago firms with credible Shopify/headless experience, rather than just agencies that happen to list Shopify as a service.

My shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Best overall fit for a startup that wants design + engineering + Shopify Plus.
• Shopify lists Praella as a Platinum Partner, with Chicago as its primary location. Its portfolio includes substantial Shopify Plus implementations, integrations, custom applications and UX work. Shopify Praella
• Praella also explicitly says it has completed 500+ projects including headless storefronts. Praella
• Why I'd interview them: strong combination of product/UX thinking and Shopify technical depth.
• BlueBolt Solutions — 415 N LaSalle Dr, River North

• Best fit if the storefront is technically complex.
• Their Chicago operation works on Shopify/Shopify Plus, including headless storefronts, private apps, Checkout Extensibility and integrations.
• I'd particularly consider them if you have an ERP/PIM, unusual product logic, subscriptions, or other systems that need to be tightly integrated.
• Atwix — 20 N Wacker Dr, Loop

• Best fit for enterprise-grade architecture and integrations.
• Atwix describes itself as a certified Shopify Plus Partner and explicitly offers headless storefronts, custom Shopify development, PWA work and complex integrations. Atwix
• Their published project range is considerably more enterprise-oriented—roughly $50K–$250K+, depending on complexity—so I'd put them on the shortlist if you're building something substantial rather than an MVP. Atwix
• Uncap — Chicago, but not downtown (near O'Hare)

• Worth knowing about despite the location. Shopify lists Uncap as a Platinum Partner and specifically lists Headless commerce among its services. Shopify Shopify
• I'd include them if you're willing to broaden beyond downtown, particularly for a B2B/DTC hybrid or complex commerce operation.

How I'd prioritize them

One important caveat: headless Shopify isn't automatically better than a well-built Shopify theme. The agencies themselves recognize that headless introduces additional architectural and maintenance complexity. If your reason is primarily "we want a faster, more modern storefront," I'd ask each agency to demonstrate why Hydrogen/Next.js + Storefront API is justified versus Shopify's native storefront architecture.

What I'd ask in the first call

1. Show me 2–3 live headless Shopify stores you've shipped. Not mockups—actual production sites.
2. Who actually wrote the frontend? Ask whether the work was done in-house or subcontracted.
3. What's your preferred architecture today—Hydrogen/Oxygen, Next.js/Vercel, or something else—and why?
4. How do you handle Shopify Functions, checkout extensibility, search, subscriptions, CMS/content and analytics in a headless setup?
5. What happens after launch? Get the expected monthly engineering/support commitment.
6. Give us a fixed-cost discovery phase before quoting the full build.

For a startup, I'd lean Praella → BlueBolt → Atwix, in that order, unless your architecture is unusually complex.

If you tell me your rough budget ($50k / $100k / $250k+), product category, and whether you're already on Shopify, I can narrow this to the 2–3 agencies I'd actually send an RFP to and compare their likely strengths, pricing, and relevant case studies.

• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611
• 7fridays - Chicago, IL 60601

If downtown Chicago is a hard requirement, I’d put these on your shortlist. I focused on agencies with evidence of Shopify + headless commerce, rather than agencies that merely advertise Shopify development.

Strongest candidates

• BlueBolt Solutions — 415 N La Salle Dr, River North. Particularly interesting for a technically demanding build: they advertise Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, and conversion optimization. Their positioning looks better suited to an established/mid-market brand than a simple Shopify theme project.
• Praella - eCommerce Agency — 203 N LaSalle St, Loop. This is probably the first agency I'd interview if you want a combination of Shopify Plus architecture + UX/design + growth. They're a Shopify Platinum Partner and are physically in the Loop.
• Atwix — 20 N Wacker Dr, Loop. A more engineering/enterprise-oriented option. Their Chicago office is downtown, and they work across Shopify Plus and other commerce platforms, with headless/PWA architecture experience. Good candidate if your storefront will have substantial integrations or unusual technical requirements.
• 1DIGITAL AGENCY | eCommerce Agency — 205 N Michigan Ave, Loop. They have Shopify and headless experience, although I'd put them behind the first three for a genuinely sophisticated Hydrogen/Next.js architecture.

One notable Chicago Shopify specialist that's not downtown

• Uncap is worth knowing about even though its current address is outside downtown. Shopify's own partner directory lists Uncap as a Platinum Partner and explicitly lists headless commerce among its services. Its specialty is particularly compelling if you're doing B2B, wholesale, ERP/PIM integrations, or unified commerce. Shopify

How I'd narrow it down

For a startup building a new headless Shopify storefront, I'd interview BlueBolt, Praella, and Atwix first.

I'd ask each one these five questions:

1. Show me 2–3 live Shopify Hydrogen/headless stores you personally shipped.
2. Are you recommending Hydrogen/Oxygen, Next.js/Vercel, or something else—and why?
3. Who will actually build it: senior in-house engineers or subcontractors?
4. What will remain in Shopify vs. the headless frontend/CMS?
5. What's your expected total cost of ownership after launch, including hosting, CMS, maintenance, and Shopify upgrades?

One important caveat: several agencies market themselves as "headless" without demonstrating much production Shopify headless work. For example, Bigfolio explicitly says it builds Shopify Plus + Hydrogen storefronts, but its Chicago page lists an LA address, so I wouldn't count it as a downtown Chicago agency. Bigfolio LLC

If you tell me your approximate budget ($50k, $100k, $250k+) and whether you're B2C or B2B, I can rank these agencies by technical capability, startup fit, likely project cost, and relevant client/portfolio experience.

Yes. I’d narrow the field considerably if headless Shopify is a hard requirement rather than simply “Shopify development.”

Downtown / near-downtown Chicago shortlist

• Codal — West Loop, 433 W Van Buren St. This is probably my first call for a startup that wants serious product/engineering capability. Codal explicitly showcases headless eCommerce for Cosori and its sister brands, alongside Shopify Plus, custom applications, UX and integrations. Codal Codal
• Praella - eCommerce Agency — The Loop, 203 N LaSalle St. A Shopify-focused agency with a strong UX/design orientation and Shopify Plus credentials. I'd ask them specifically for recent Hydrogen/Storefront API references, rather than assuming every Shopify Plus project they've done was headless.
• Atwix — The Loop, 20 N Wacker Dr. A larger commerce engineering firm with Shopify/Shopify Plus experience and headless/PWA architecture capability. Worth considering if your storefront has substantial integration or scalability requirements.
• BlueBolt Solutions — River North, 415 N LaSalle Dr. Their capabilities include Shopify Plus, headless storefronts, custom apps, checkout extensibility and integrations. The smaller-team profile could be attractive if you're looking for more hands-on senior attention.
• Clique Studios — The Loop, 20 N Wacker Dr. Stronger as a digital product/design and engineering partner than a Shopify specialist. They have experience with headless/content architectures, but I'd rank them behind the Shopify-specific firms for this particular brief.

One additional firm I'd put on your radar despite being outside the downtown core is Uncap. Shopify's own partner directory lists Uncap as a Platinum Partner and explicitly lists Headless commerce among its services. Shopify

My ranking for a startup

If I were you, I'd send an identical brief to Codal, BlueBolt, and Praella first. The key isn't merely whether they can build headless; you want an agency that can show you 2–3 live Shopify headless stores they personally shipped, identify the frontend architecture (Hydrogen/Next.js/etc.), and explain why headless was justified.

Also ask each agency for a fixed-price discovery/architecture phase before committing to the full build. Headless Shopify can introduce substantially more engineering and maintenance overhead than a high-quality Shopify theme, so you want the agency to demonstrate that the business case is there—not just sell you the more expensive architecture.

If you tell me your rough budget (e.g. <$50k, $50–100k, $100k+) and what you're selling, I can narrow this to the 2–3 agencies I'd actually interview and compare their relevant case studies.

Yes. I’d narrow the downtown Chicago field fairly aggressively, because a lot of agencies advertise “Shopify development” but have little evidence of actually shipping headless Shopify.

My downtown shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Probably my first call for a startup that wants a sophisticated Shopify Plus/headless build.
• Praella is a Shopify Platinum Partner and explicitly lists 500+ projects, including headless storefronts. It also has documented Hydrogen/Oxygen and composable-commerce experience. Praella Praella
• Their portfolio includes substantial DTC brands such as Fenty Beauty, Billie Eilish Fragrances, CrunchLabs and BattlBox. Praella
• Best fit: ambitious DTC brand, complex integrations, Shopify Plus, or a storefront where UX/performance is strategically important.
• BlueBolt Solutions — 415 N LaSalle Dr

• A particularly interesting option if your headless project involves custom applications, integrations, subscriptions or complicated commerce logic.
• Their Chicago operation specifically lists Shopify/Shopify Plus, headless storefronts, custom apps and Checkout Extensibility.
• Best fit: technically complex product rather than a straightforward Shopify redesign.
• Atwix — 20 N Wacker Dr

• Downtown/Loop presence with substantial commerce-engineering experience.
• Their Shopify practice explicitly includes headless commerce solutions, API integrations with ERP/CRM/PIM systems, Shopify Plus and migrations. Atwix
• Best fit: a startup with enterprise ambitions, lots of backend integrations, or a technically demanding architecture.
• Americaneagle.com, Inc. — 200 W Jackson Blvd

• Major digital-commerce firm with a downtown office. I'd consider them if your startup is already operating at fairly substantial scale and needs broader enterprise capabilities.
• Caveat: they're much broader than Shopify/headless, so I'd want to see specific recent Shopify Hydrogen/Storefront API projects before putting them ahead of Praella or BlueBolt.

One I'd put on the "verify before shortlisting" list

1DIGITAL AGENCY | eCommerce Agency — 205 N Michigan Ave

They're genuinely downtown and have Shopify/Shopify Plus experience, but the public evidence I found is stronger for Shopify development, migrations and integrations than for sophisticated headless implementations. I'd ask them to show 2–3 recent headless Shopify builds before spending time on a proposal.

My ranking for a startup

One important distinction: “headless Shopify” shouldn't automatically mean Hydrogen. I'd ask each agency whether they'd recommend Hydrogen/Oxygen, Next.js + Storefront API, or conventional Shopify Online Store 2.0 for your business—and why. A good agency should be willing to tell you not to go headless if the additional engineering/maintenance isn't justified.

For a founder evaluating agencies, I'd make the first-call questions:

1. Show me two live headless Shopify stores you personally built.
2. Who actually writes the frontend—senior in-house engineers or subcontractors?
3. Hydrogen/Oxygen vs. Next.js: which would you choose for us and why?
4. How do you handle Shopify checkout, customer accounts, subscriptions and Shopify Functions in a headless architecture?
5. What CMS do you recommend alongside Shopify—Sanity, Contentful, Storyblok, etc.—and why?
6. What's your post-launch retainer and who owns the code?
7. Can you give me a fixed-fee MVP and a separate estimate for the “nice-to-have” architecture?

If you tell me your approximate budget ($50k, $100k, $200k+), product category, current platform, and whether you need Shopify Plus, I can narrow these to the 3 agencies I'd actually invite to pitch and compare their likely strengths, weaknesses and relevant case studies.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Americaneagle.com, Inc. - 200 W Jackson Blvd Fl 22, Chicago, IL 60606, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• Digital Bridge Solutions - 412 S Wells St 6th floor, Chicago, IL 60607, United States
• Brand Vision Marketing - Web Design & Branding - 30 N Michigan Ave #504, Chicago, IL 60602, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Swarming Technology - 7610 W State St Fl 2, Wauwatosa, WI 53213, United States
• ISKPRO - 400 W Erie St, Chicago, IL 60654, United States

• Fresh Design Studio - 222 W Merchandise Mart Plaza Suit 1212, Chicago, IL 60654, United States
• ALX Creatives - 420 W Huron St, Chicago, IL 60654
• Wunderman Thompson Commerce & Technology - 71 S Wacker Dr Ste 3550, Chicago, IL 60606, United States

Yes. I’d narrow the field considerably: headless Shopify experience is much rarer than ordinary Shopify development, and for a startup I’d prioritize an agency that can show live headless Shopify builds, not just claim “headless” as a service.

My Chicago shortlist

• Praella - eCommerce Agency — Loop, 203 N LaSalle St

• One of the strongest local candidates. It is Shopify-focused, a Shopify Platinum Partner, and has a downtown Chicago office.
• Best for: a startup that wants strong Shopify/Shopify Plus expertise plus design, development and growth support.
• Caveat: I’d specifically ask them to show you 2–3 production headless Shopify examples rather than assuming their Shopify Plus experience means headless experience.
• BlueBolt Solutions — River North, 415 N La Salle Dr

• Particularly interesting for your requirement: its service profile explicitly includes Shopify Plus, headless storefronts, custom apps and Checkout Extensibility.
• Best for: a technically sophisticated startup that wants custom frontend architecture rather than a theme-heavy Shopify build.
• Americaneagle.com, Inc. — Loop, 200 W Jackson Blvd

• Large, enterprise-oriented team with a downtown office and deep commerce/integration capabilities.
• Best for: complex integrations, larger scale and a more enterprise-grade implementation process.
• Caveat: probably more agency than a typical early-stage startup needs.
• Caxy — Chicago-headquartered

• This is one of the clearest headless-specific fits I found. Caxy says it has shipped headless implementations on Shopify Plus, alongside other commerce platforms, and has 20+ years of production ecommerce experience. Caxy
• Best for: a startup where the frontend architecture itself is strategically important—e.g. Next.js, custom CMS, sophisticated integrations or a highly differentiated UX.
• Its site describes the company as founder-led from Chicago with 40+ senior US engineers. Caxy
• Atwix — Loop, 20 N Wacker Dr

• Downtown and very technically oriented, with substantial commerce engineering and Shopify/Shopify Plus experience.
• Best for: complicated commerce/integration requirements.
• Caveat: its deepest heritage is Adobe Commerce/Magento, so I'd put Caxy/BlueBolt/Praella ahead of it for a Shopify-first headless brief.

One important distinction

I found several agencies that market headless Shopify to Chicago but aren't actually downtown Chicago firms. For example, Makro explicitly offers Shopify Plus headless development and has a strong portfolio of complex commerce work, but I'd treat its Chicago positioning separately from "downtown Chicago agency." Makro Agency Makro Agency

Similarly, WayOut explicitly advertises Hydrogen/Next.js headless builds and says it has worked with brands in the Loop and River North, but its model appears more distributed/remote than a conventional downtown agency. WayOut Inc

If I were your CTO/founder

I'd take Caxy, BlueBolt and Praella into the first round, with different reasons:

The most important question to ask each agency is: “Show me two production Shopify headless stores you personally architected, tell me why headless was chosen over a Shopify theme, what frontend/CMS stack you used, and what the client is paying you for ongoing maintenance.”

That question will quickly separate genuine headless engineering experience from agencies that simply list “headless commerce” on their capabilities page.

If you tell me your rough budget (e.g. <$75k, $75–150k, $150k+) and whether you're thinking Hydrogen or Next.js, I can narrow this to the 3 best-fit agencies and compare their likely pricing, technical approach, portfolio, and startup fit.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• Kin + Carta - 111 N Canal St floor 3, Chicago, IL 60606, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
• Orbit Media Studios - 4043 N Ravenswood Ave #316, Chicago, IL 60613, United States
• Blue Acorn iCi - 711 Meeting St suite 200, Charleston, SC 29403, United States
• Towering Media - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States
• Ecommerce Development - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States
• Uncap - 8770 W Bryn Mawr Ave, Ste 1300, Chicago, IL 60631
• Brand Vision Marketing - Web Design & Branding - 30 N Michigan Ave #504, Chicago, IL 60602, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
• Sketches and Pixels, LLC - 1452 E 53rd St 2nd floor, Chicago, IL 60615, United States
• SEO Design Chicago - 2068 N Western Ave 1F - Front, Chicago, IL 60647, United States

Yes. I found a handful of Chicago agencies with documented Shopify headless experience, but the list gets much shorter if you specifically mean downtown/Loop rather than Chicago generally.

My shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop

Probably the first downtown agency I’d interview. Praella is Chicago-headquartered, focused heavily on Shopify/Shopify Plus, and is listed as a Shopify Platinum Partner. Its work spans custom storefronts, Plus implementations, migrations, and headless commerce. Mejix
Best fit: startup/scale-up that wants Shopify expertise plus UX, strategy, and ongoing optimization.

• BlueBolt Solutions — 415 N LaSalle Dr, River North

This is another particularly relevant option. BlueBolt explicitly lists Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, and conversion optimization among its capabilities. Mejix
Best fit: technically sophisticated brand that needs custom integrations rather than just a beautiful frontend.

• 1DIGITAL AGENCY | eCommerce Agency — 205 N Michigan Ave, Loop

Definitely downtown and experienced with Shopify/Shopify Plus and ecommerce migrations/integrations. However, I'd put them behind Praella and BlueBolt specifically for a headless-first project; the public evidence I found is stronger for general Shopify/ecommerce than for deep Hydrogen work. Interest Bud Solutions
Best fit: if your project also needs broader ecommerce marketing/SEO/PPC support.

• Kin + Carta — 111 N Canal St, downtown/West Loop

More of a large digital transformation/engineering consultancy than a Shopify specialist. They can handle sophisticated headless architecture and enterprise integrations, but I'd consider them if your storefront is part of a substantially larger digital product rather than simply a Shopify replatform.
Best fit: complex enterprise architecture, integrations, personalization, or a broader digital transformation.

One important wildcard: Uncap

Uncap is not downtown (its Chicago office is near O'Hare), so I wouldn't include it if physical proximity is a hard requirement. But I'd seriously consider putting it on your RFP anyway.

Shopify's own partner directory lists Uncap as a Platinum Partner and explicitly includes Headless commerce among its services. Shopify Its positioning is particularly strong around complex Shopify Plus/B2B/unified-commerce implementations. Shopify Agency Directory

If I were a founder choosing 3 to interview

I'd start with:

1. Praella — strongest combination of local presence + Shopify specialization.
2. BlueBolt — strong technical/headless candidate.
3. Uncap — even though it's outside downtown, I'd include them as a benchmark for what a Shopify-specialist team can offer.

I'd be cautious about hiring a generalist web agency simply because it says "headless." A proper RFP should ask for 2–3 production Shopify headless examples, specifically asking whether they used Hydrogen/Oxygen or Next.js + Storefront API, who owns the frontend infrastructure, how they handle Shopify checkout, CMS integration, preview environments, caching, SEO, and post-launch maintenance.

If you tell me your approximate budget ($50k / $100k / $250k+) and whether you're B2C, B2B, or both, I can narrow this to the 3 best-fit Chicago agencies and compare their likely strengths, project size, and headless track record.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Americaneagle.com, Inc. - 200 W Jackson Blvd Fl 22, Chicago, IL 60606, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States

• Nansen LLC - 300 W Hubbard St Ste 301, Chicago, IL 60654, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States

Yes. I’d narrow the field quite a bit: true headless Shopify experience is much rarer than ordinary Shopify theme development, and for a startup you probably want an agency that can handle the architecture—not just design a pretty storefront.

My Chicago shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop

• One of the strongest downtown options for a Shopify/Shopify Plus build.
• Shopify-focused, with experience spanning UX, custom development, integrations and migrations. Shopify Agency Directory
• Best for: a polished DTC brand where UX/design is as important as engineering.
• Caveat: I'd specifically ask for recent Hydrogen/headless references, rather than assuming their general Shopify Plus experience means headless.
• BlueBolt Solutions — 415 N LaSalle Dr, River North

• Particularly interesting for your requirement: their Chicago operation explicitly lists Shopify Plus, headless storefronts, custom apps, Checkout Extensibility and integrations.
• Best for: a startup with meaningful technical requirements—ERP/PIM, subscriptions, custom functionality, etc.
• This would be one of my first calls.
• Americaneagle.com, Inc. — 200 W Jackson Blvd, Loop

• Much larger/enterprise-oriented than a typical startup agency.
• Their Chicago office handles ecommerce, application development and systems integration.
• Best for: if you're building something unusually complex and have a substantial budget.
• Caveat: probably more agency overhead than you need for an early-stage company.
• Atwix — 20 N Wacker Dr, Loop

• Downtown and technically oriented, with substantial commerce-development experience and Shopify/Shopify Plus capability.
• Best for: integration-heavy commerce or a company that expects its storefront to become a serious software platform.
• Their heritage is stronger in Adobe/Magento than pure Shopify, so I'd require concrete headless Shopify case studies before shortlisting them.
• Adage Technologies — 10 S Riverside Plaza, Loop

• Chicago-headquartered custom software/digital-experience agency with ecommerce, integrations and custom application development capabilities.
• Best for: a more composable architecture where Shopify is only one piece of the stack.
• I'd put them in the "technical architecture candidate" bucket rather than Shopify-specialist bucket.

One notable specialist outside downtown

Uncap is worth knowing about even though its office is near O'Hare rather than downtown. It is a Chicago Shopify Platinum Partner with a strong B2B/unified-commerce focus. Shopify Agency Directory Uncap

If you're building a B2B + DTC business, I'd put Uncap on the shortlist despite the location.

What I'd do in your shoes

For a startup, I'd initially interview BlueBolt + Praella + one more technically deep agency rather than sending an RFP to 10 Shopify shops.

The key questions I'd ask each:

1. "Show me two Shopify Hydrogen/headless stores you personally shipped in the last 18 months."
2. "Who were the engineers on those projects, and would those people be on ours?"
3. "Why did those clients choose headless instead of a high-performance Shopify theme?"
4. "What are you recommending for our CMS—Sanity, Contentful, Shopify's native content, or something else—and why?"
5. "What does the architecture look like between Shopify, the frontend, CMS, search, analytics and third-party services?"
6. "What is your expected ongoing engineering cost after launch?"

That last question matters a lot. Headless can give you a substantially better custom experience, but it also turns your storefront into a software application that needs ongoing engineering. One Chicago agency I found actually makes a point of assessing whether headless is justified before recommending it. ConversionEX

For context, a specialist such as Caxy—headquartered in Chicago at 212 W Van Buren—explicitly advertises Shopify Plus headless and has 20+ years of production ecommerce experience; however, its published project range is roughly $150K–$500K, so it may be more appropriate once your scope/budget is substantial. Caxy

My initial ranking for a startup: BlueBolt → Praella → Caxy → Atwix/Adage, with Uncap moving near the top if you're B2B-heavy.

If you tell me your rough budget ($50–100k, $100–200k, $200k+) and whether you're DTC, B2B, or both, I can narrow this to 3 agencies and compare their likely fit, headless stack, pricing level, and relevant case studies.

If you’re a Chicago startup founder looking for a headless Shopify storefront partner, I’d focus less on “Shopify designers” and more on agencies that can handle the architecture: Shopify Storefront API, Hydrogen/React or Next.js, CMS integration, performance, analytics, and ongoing engineering.

A few Chicago-area agencies worth evaluating:

How I’d shortlist for a startup

For a startup founder, I’d probably take first calls with:

1. Caxy — if your storefront is really a product experience (custom UX, integrations, marketplace-like flows, complex backend). Caxy
2. Praella — if you want a Shopify-native team that understands conversion, growth, and operations.
3. Uncap — if you expect complexity around B2B, catalogs, ERP/PIM, or unified commerce.
4. BlueBolt — if you need a technical commerce partner rather than a marketing-led agency.

Questions I’d ask every agency before hiring

• How many production headless Shopify stores have you launched (not prototypes)?
• Do you recommend Hydrogen vs Next.js, and why for our use case?
• Who owns the frontend codebase after launch?
• What CMS do you pair with Shopify (Sanity, Contentful, Shopify metaobjects, etc.)?
• How do you handle: - cart state
• checkout handoff
• subscriptions
• search/filtering
• analytics attribution
• SEO rendering
• What is your post-launch engineering/support model?

One caution: headless Shopify is powerful, but it adds operational overhead. A good agency should be willing to tell you if a highly optimized Shopify theme would outperform headless for your current stage. ConversionEX

If you share your industry (CPG, fashion, SaaS + commerce, marketplace, etc.), current revenue/stage, and whether you need Shopify Plus, I can narrow this to the 3–5 agencies I’d actually interview.

• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Towering Media - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States
• Ecommerce Development - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States

• Avensia - Digital Commerce Solutions For Businesses - 20 W Kinzie St, Chicago, IL 60654, United States
• SITE IT NOW - 1016 W Jackson Blvd, Chicago, IL 60607, United States

Yes. I found a few Chicago-based agencies with credible headless Shopify experience, but the shortlist gets much smaller if you mean actually downtown rather than “serves Chicago.”

My shortlist

• BlueBolt Solutions — River North, 415 N LaSalle Dr

Probably the strongest downtown fit for a technically complex build. They specifically list Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, subscriptions, and CRO. Their positioning is more engineering/ecommerce than traditional creative agency, which I’d favor for a headless project.

• Praella - eCommerce Agency — Loop, 203 N LaSalle St

A Shopify/Shopify Plus specialist with a downtown Chicago office and Platinum Partner status. They do full Shopify implementations and are worth interviewing if you want a more established Shopify-focused agency rather than a general digital shop.

• Clique Studios — Loop, 20 N Wacker Dr

A much broader digital-product agency. Their Chicago team does custom engineering, ecommerce, headless/content architectures and integrations. I'd consider them if your storefront is also going to function as a sophisticated brand/content experience, though they're less Shopify-specialized than BlueBolt or Praella.

• Atwix — Loop, 20 N Wacker Dr

Downtown and highly technical, with extensive commerce-platform experience and Shopify/Shopify Plus capabilities. However, their heritage is stronger in Adobe Commerce/Magento, so I'd specifically ask for recent Shopify Hydrogen/React storefront examples before putting them on the final shortlist.

One Chicago agency I'd include even though it isn't downtown

Uncap is worth serious consideration. It's Chicago-based rather than downtown, and Shopify's own partner directory identifies it as a Platinum Partner offering headless commerce. Its sweet spot appears to be sophisticated Shopify/Shopify Plus businesses, particularly B2B/unified-commerce and integration-heavy builds. Shopify

How I'd narrow it for a startup

If I were running the RFP, I'd interview BlueBolt, Praella, and Uncap first.

More importantly, don't just ask an agency “Can you build headless Shopify?” Almost every modern Shopify agency will say yes. Ask them to show you:

1. 2–3 live Hydrogen/Next.js Shopify storefronts they personally built.
2. Which parts were actually built by their team vs. subcontractors.
3. Their preferred architecture: Hydrogen/Oxygen vs. Next.js/Vercel, and why.
4. How they handle SEO, redirects, structured data, caching, analytics and Core Web Vitals.
5. How they'll handle Shopify's Checkout Extensibility and what remains inside Shopify.
6. Who owns the code and infrastructure after launch.
7. A realistic maintenance budget after launch.

One useful sanity check: headless isn't automatically better. Some Shopify specialists explicitly recommend a conventional Shopify theme when it can accomplish the business requirements, because headless adds engineering and ongoing maintenance. Flux Agency ConversionEX

If you tell me your approximate budget ($50k, $100k, $250k+), product category, and whether you're already on Shopify, I can narrow this to the 3 best-fit agencies and compare their likely strengths, headless stack, location, Shopify credentials, and publicly documented work.

Yes. I found a few downtown Chicago firms that look relevant, but the shortlist gets much smaller once you require actual headless Shopify experience rather than generic Shopify development.

My shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Probably the strongest first call if you're looking for a full-service Shopify Plus partner.
• Shopify lists Praella as a Platinum Partner, with Chicago as its primary location. Its listed services include headless commerce, custom apps/integrations, migrations, CRO and Shopify Plus work. Shopify
• Good fit if you need strategy + UX/design + engineering rather than simply hiring a frontend development shop.
• BlueBolt Solutions — 415 N LaSalle Dr

• Particularly interesting for a startup that expects technically complicated commerce.
• Their Chicago operation focuses on Shopify/Shopify Plus and lists headless storefronts, custom apps, Checkout Extensibility, subscriptions and integrations among its capabilities.
• I'd put them high on the list if your headless architecture involves an ERP/PIM/CRM or unusual commerce logic.
• Americaneagle.com, Inc. — 200 W Jackson Blvd

• Much larger/enterprise-oriented option.
• Worth considering if you're anticipating significant scale, multiple systems, internationalization or a complex organizational rollout. Their Chicago office is in the Loop.
• I'd favor them over a boutique if your project is becoming an enterprise commerce transformation rather than just a storefront build.
• Adage Technologies — 10 S Riverside Plaza

• Downtown Chicago software/digital-experience firm with substantial custom engineering capability.
• More of a custom digital product/composable commerce shop than a Shopify-specialist boutique, so I'd specifically ask for recent Shopify Hydrogen/Storefront API references before putting them on the RFP list.

One important non-downtown option

Uncap is worth knowing about even though its current Chicago address is near O'Hare rather than downtown. Shopify lists it as a Platinum Partner and explicitly lists headless commerce among its services. Its positioning is particularly strong around complex B2B/unified commerce, ERP integrations and large catalogs. Shopify

Who I'd contact first

For a startup founder, I'd probably do an initial three-way evaluation:

1. Praella — strongest Shopify-specific full-service candidate.
2. BlueBolt — strongest candidate if engineering/integrations are the hard part.
3. Uncap — add them if you have B2B, ERP/PIM, complex catalog or operational requirements.

I wouldn't choose based on the fact that an agency says "headless" on its website. Shopify itself treats Hydrogen/headless commerce as a distinct capability, and its partner directory lets you filter specifically for headless commerce. Shopify Shopify

What I'd ask each agency

For your first call, ask these five questions:

• "Show me 2–3 Shopify headless stores you personally built, preferably using Hydrogen or Next.js."
• "Which parts of the implementation were actually headless, and which remained native Shopify?"
• "Who will own the architecture and frontend code after launch?"
• "What CMS would you pair with Shopify, and why?"
• "Can you give me a reference from a company roughly our size rather than an enterprise case study?"

That last question is particularly important for a startup: you don't want to pay enterprise-agency prices for a team that has mostly built $1M+ transformation projects.

If you tell me your approximate budget, product category, current platform, and whether you want Hydrogen vs. Next.js, I can narrow this to 3 agencies and compare them on likely fit, headless track record, size, pricing, and relevant case studies.

Yes. I’d narrow the field quite a bit, because “Shopify agency” and “has actually shipped headless Shopify” are very different things.

My Chicago shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Probably the first agency I’d interview for a startup that wants a serious Shopify Plus/headless build.
• They’re a Shopify Platinum Partner with a downtown Chicago office, and their practice centers heavily on Shopify/Shopify Plus. Shopify
• Best for: a polished consumer storefront where UX/design and Shopify architecture both matter.
• BlueBolt Solutions — 415 N LaSalle Dr, River North

• Particularly interesting for a technical build: Shopify Plus, headless storefronts, custom apps, Checkout Extensibility, subscriptions and integrations are all in its stated capabilities.
• Best for: a startup whose headless architecture has meaningful technical requirements rather than simply wanting a flashy React frontend.
• Kin + Carta — 111 N Canal St

• This is the enterprise/technology-consulting option. Its Chicago team has deep product engineering and digital-transformation capabilities.
• Best for: a more complex commerce product involving multiple systems, personalization, data, or substantial custom engineering.
• Caveat: I'd specifically ask which current team would execute the Shopify work, given the company's evolution under Valtech.
• Atwix — 20 N Wacker Dr

• Downtown and very technically oriented. Its commerce practice spans Shopify/Shopify Plus alongside other enterprise commerce platforms.
• Best for: integration-heavy commerce, particularly if Shopify is one component of a larger architecture.
• Wunderman Thompson Commerce & Technology — 71 S Wacker Dr

• A much larger enterprise agency with Chicago roots through Gorilla Group and substantial commerce-technology experience.
• Best for: larger budgets, enterprise processes, and complicated commerce ecosystems. Probably overkill for an early-stage startup.

One important non-downtown option

Uncap is worth putting on your RFP list even though its current office is near O'Hare rather than downtown. Shopify's own partner directory lists Uncap as a Platinum Partner and explicitly lists headless commerce among its services. Shopify

That makes it one of the stronger Shopify-specific candidates, particularly if you're building B2B or have ERP/PIM/CRM integration requirements.

How I'd rank them for a startup

I'd start conversations with Praella, BlueBolt, and Uncap rather than sending an RFP to 10 agencies.

One thing I'd insist on during the first call: ask them to show you 2–3 live headless Shopify stores they personally built, identify whether they used Hydrogen/Remix, Next.js, or another frontend, and tell you exactly which team members would work on yours. A lot of agencies use “headless” in their marketing without having much production experience.

Also, don't assume headless is automatically the right architecture. For example, some Shopify specialists explicitly advise clients to stay with a well-built Liquid storefront unless the performance/content/experience requirements genuinely justify Hydrogen or another headless stack. ConversionEX

If you tell me your approximate budget, product category, and whether you're on Shopify Plus already, I can narrow this to the 3 best agencies and give you a specific RFP/agency-selection scorecard.

• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States

Yes. I’d narrow the field considerably rather than treating every Chicago Shopify shop as a headless candidate. I found several agencies with credible evidence of Shopify headless experience, and a few are actually downtown/Loop.

My Chicago shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Probably the first agency I’d interview for a startup that wants a polished Shopify Plus build.
• They’re Chicago-headquartered and Shopify-focused, with a downtown office. Their positioning is heavily Shopify/Shopify Plus.
• Caveat: I’d specifically ask them to show recent headless Shopify launches rather than assuming their general Shopify expertise translates to your architecture.
• BlueBolt Solutions — 415 N LaSalle Dr, River North

• Strong technical fit: Shopify Plus, headless storefronts, custom/private apps and Checkout Extensibility are all explicitly part of their offering.
• Particularly interesting if your storefront needs significant integrations or custom commerce functionality.
• This would be one of my first calls for a technically ambitious startup.
• WHQ — 24 E Washington St, Loop

• A particularly interesting option if the project is as much about digital product experience as commerce.
• Their capabilities include composable/headless commerce, platform architecture, product configurators, B2B/B2C commerce, catalog systems and UX/conversion strategy.
• I'd put them on the shortlist if you have a differentiated product experience rather than a conventional DTC store.
• Atwix — 20 N Wacker Dr, Loop

• Downtown and very engineering-oriented.
• They have deep ecommerce implementation/integration experience and work with Shopify/Shopify Plus, although their background is broader than Shopify.
• Better fit if your headless storefront is part of a larger commerce architecture involving ERP, PIM, integrations, etc.
• Americaneagle.com, Inc. — 200 W Jackson Blvd, Loop

• Enterprise-scale digital commerce agency with a downtown Chicago office.
• I'd consider them if you're anticipating substantial integrations, internationalization, organizational complexity or a very large storefront.
• Probably more agency than a typical startup needs, though.

One Chicago Shopify specialist I'd also interview

Uncap is worth including despite not being downtown—their Chicago office is near O'Hare. Shopify's own partner directory lists them as a Platinum Partner and explicitly lists headless commerce among their services. Shopify

They appear particularly strong for B2B, large catalogs, ERP integrations and complicated commerce operations. If your startup has those characteristics, I'd put them ahead of some of the downtown agencies. Shopify Bee Apps

If I were choosing the first 3 calls

I'd start with:

1. BlueBolt — strongest apparent combination of downtown location + Shopify Plus + headless + engineering.
2. Praella — Shopify-specialist option with a genuine downtown presence.
3. WHQ — particularly compelling for a differentiated, experience-heavy storefront.

There are also Chicago agencies outside downtown advertising very explicit headless Shopify capabilities. For example, Makro lists headless as a core Shopify Plus service and has 31 published cases, while WayOut specifically advertises Hydrogen/Next.js headless builds and says it has migrated a $12M brand to headless Shopify. Makro Agency WayOut Inc

One important founder-to-founder caveat

I'd not automatically choose headless just because you can. A good agency should be willing to challenge the premise. One Chicago Shopify specialist explicitly says it assesses whether headless is warranted because the added architecture and maintenance aren't always justified. ConversionEX

For your RFP, I'd ask each agency for:

• 2–3 live Shopify headless stores they built, preferably using Hydrogen/Next.js
• What they own vs. subcontract
• Their preferred architecture: Hydrogen/Oxygen vs. Next.js/Vercel
• How they handle Shopify checkout, cart, customer accounts and preview environments
• CMS recommendation (Sanity, Contentful, Shopify metaobjects, etc.)
• Expected ongoing engineering cost after launch
• Performance/Core Web Vitals results from actual launches
• A realistic all-in budget and timeline, including design, development, integrations and post-launch support

If you tell me your approximate budget, product/category, current stack (if any), and whether you want Hydrogen or Next.js, I can narrow this to the 3 best-fit Chicago agencies and compare their likely strengths, pricing tier, portfolio and headless credentials.

• Chicago Internet(Fireplace's Specialist) Marketing Company - Kensium LLC - 200 S Wacker Dr, Chicago, IL 60606, United States

Yes. I’d narrow the field quite a bit if “downtown Chicago” + demonstrated Shopify headless experience are both hard requirements.

My shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop.

This is probably the strongest fit I found. Praella is a Shopify-focused agency with a downtown office and explicitly offers Hydrogen/Oxygen, composable commerce, and headless/PWA work. Its portfolio is substantial, and its case-study library can be filtered for “headless / PWA” and “Shopify Hydrogen build.” Praella Praella
Why I'd talk to them: They appear capable of taking a startup from architecture through design/development rather than simply doing Shopify theme work.

• WHQ — 24 E Washington St, Loop.

WHQ is particularly interesting if your storefront has a complex product/catalog experience. Its capabilities include composable/headless commerce, product configurators, specification tools, product finders, B2B/B2C commerce, and product-data architecture.
Why I'd talk to them: Potentially a better fit than a conventional Shopify agency if your startup needs a highly customized commerce UX.

• BlueBolt Solutions — 415 N LaSalle Dr, River North.

BlueBolt is another downtown option with Shopify/Shopify Plus experience and custom ecommerce development/integration capabilities.
Caveat: I found stronger public evidence for its Shopify Plus/custom-commerce work than for a deep portfolio of Shopify Hydrogen builds, so I'd specifically ask for recent headless references before putting it on the final shortlist.

• Atwix — 20 N Wacker Dr, Loop.

Atwix has a downtown office and substantial enterprise-commerce engineering experience, including Shopify/Shopify Plus.
Caveat: Its center of gravity is broader commerce engineering/Adobe Commerce, so I'd consider it if your headless storefront has serious integrations, ERP, PIM, or enterprise architecture requirements rather than simply wanting a premium Shopify frontend.

One Chicago agency I'd also interview despite not being downtown

Uncap is worth including if “Chicago-based” matters more than literally being downtown. Shopify lists Uncap as a Platinum Partner, and its services explicitly include headless commerce. Shopify Its specialty is more B2B/unified commerce, though, so I'd rank it differently for a consumer startup.

How I'd rank them for a startup

One important wrinkle: don't let an agency sell you on headless simply because you're a startup. Praella's own work illustrates the point: in one Rad Power Bikes project, it actually moved the merchant away from headless and back toward native Shopify Plus because the headless architecture had become unnecessarily costly/complex. Praella That's the kind of architectural honesty I'd look for.

For your RFP, I'd ask each agency for 2–3 live Shopify headless sites they personally built, specifically requesting the frontend framework (Hydrogen/Next.js/etc.), CMS, hosting, Shopify APIs, checkout architecture, and post-launch maintenance cost. That will separate genuine headless specialists from agencies that simply put “headless” on their services page.

If you tell me roughly your startup's product/category, expected GMV, catalog size, and whether you already have a Shopify store, I can narrow this to the best 3 agencies and compare their likely fit, pricing tier, headless stack, and relevant case studies.

• Digital Bridge Solutions - 412 S Wells St 6th floor, Chicago, IL 60607, United States

Yes. I found a few downtown/central Chicago firms with credible headless-commerce experience, but the shortlist gets much smaller once you require both Shopify and genuinely headless architecture.

My shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St, Loop

• Probably the first agency I'd interview for a startup-to-growth Shopify build.
• Chicago-headquartered and focused heavily on Shopify/Shopify Plus.
• Public materials describe headless capability, and third-party agency information specifically identifies Shopify Storefront API/Hydrogen work. Shopify Agency Directory
• Best for: brand-led DTC, Shopify Plus, sophisticated UX, and a team that can stay with you beyond launch.
• BlueBolt Solutions — 415 N La Salle Dr, River North

• Very relevant if you want a technically sophisticated commerce partner.
• Their positioning spans Shopify/Shopify Plus, custom integrations, and headless delivery; they're also associated with Optimizely's headless ecosystem.
• Best for: technically complex storefronts, integrations, personalization, and experimentation.
• Atwix — 20 N Wacker Dr, Loop

• Downtown and substantially more engineering-oriented than a typical Shopify design shop.
• Their work spans complex commerce implementations and integrations, including Shopify Plus, although their heritage is broader commerce/Adobe rather than exclusively Shopify.
• Best for: a headless project with serious ERP/PIM/integration requirements.
• Caxy Interactive — 212 W Van Buren St, Loop

• This is one of the strongest pure engineering options I found.
• Caxy explicitly says it has shipped Shopify Plus headless storefronts and has 20+ years of production ecommerce experience. Their Chicago HQ is at 212 W Van Buren. Caxy
• They quote roughly $150K–$500K for most custom software projects, with technology assessments starting around $15K. Caxy
• Best for: a startup whose "storefront" is really becoming a custom digital commerce product.
• Mobify Chicago — 350 N Orleans St, River North

• Particularly interesting if headless architecture is the primary requirement rather than simply "Shopify development."
• Mobify has deep roots in composable/headless storefront technology, although I'd verify exactly what the current Chicago team delivers and which Shopify implementations they've done recently.
• Best for: enterprise-grade composable/headless architecture.

One non-downtown agency I'd still interview

Uncap is not downtown—it is near O'Hare—but I'd include it if you're willing to relax the geographic constraint. It's a Chicago-headquartered Shopify Platinum Partner with a strong focus on complex Shopify/B2B/unified commerce. Its public materials explicitly mention headless storefront architecture using Shopify's Storefront API and Hydrogen. Shopify Agency Directory

How I'd narrow this for a startup

I'd put Praella, Caxy, and BlueBolt into the first round.

The key distinction I'd make in your RFP is "Show me 2–3 Shopify headless stores you personally shipped, not just headless commerce projects." A surprising number of agencies market "headless" but have relatively little production Shopify/Hydrogen experience.

I'd also ask each agency:

• Hydrogen/Oxygen vs. Next.js/Vercel: what would they choose and why?
• What CMS would they pair with Shopify—Sanity, Contentful, Shopify metaobjects, or something else?
• Who owns the architecture after launch?
• Can they show real Lighthouse/Core Web Vitals data from a comparable production store?
• What Shopify functionality becomes harder in their architecture?
• What is the expected ongoing engineering cost after launch?
• Can they provide references from founders/VPs who actually worked with the delivery team?

One other important point: don't let an agency sell you headless simply because it's technically interesting. Some Shopify agencies themselves now recommend conventional Shopify/Liquid when headless doesn't produce enough business value. For example, ConversionEX explicitly says it assesses whether Hydrogen's added complexity is justified before recommending it. ConversionEX

If you tell me your rough GMV/ARR, product count, current platform, and why you want headless (performance, highly custom UX, content, personalization, internationalization, etc.), I can narrow these to the 3 agencies I'd actually take meetings with and compare their likely fit/cost/technical approach.

Yes. I’d narrow the downtown search considerably rather than treating every Chicago Shopify shop as a headless specialist.

My shortlist

• Praella - eCommerce Agency — 203 N LaSalle St, Loop. This is probably the strongest fit if you want a full-service Shopify Plus partner. Praella is a Shopify Platinum Partner, has its North American headquarters in Chicago, and explicitly lists headless/PWA and Shopify Hydrogen builds in its portfolio. It also reports 500+ projects, including headless storefronts. Shopify Praella Praella Praella

praella.com

• BlueBolt Solutions — 415 N LaSalle Dr, River North. Another particularly credible option. Shopify's partner directory lists BlueBolt as a Chicago-based Plus Partner offering headless commerce, while BlueBolt's own technical practice specifically cites Hydrogen, Next.js, API-first storefronts, and integrations. Its HarperCollins work is a particularly relevant example of Shopify Plus + headless CMS/commerce. Shopify BlueBolt Solutions BlueBolt Solutions

blueboltsolutions.com

• Americaneagle.com, Inc. — 200 W Jackson Blvd, Loop. Worth considering if you're building something more enterprise-grade. Its Chicago office is downtown and the agency has substantial composable/headless commerce capabilities, although I would specifically ask for recent Shopify Hydrogen/Next.js references rather than assuming its broader headless expertise translates directly to Shopify.
• Avensia - Digital Commerce Solutions For Businesses — 20 W Kinzie St, River North. More enterprise/B2B-oriented than startup-oriented. It could make sense if your storefront has complex product data, PIM, ERP, wholesale, or international-commerce requirements. I'd treat Shopify-headless experience as something to validate during the pitch rather than its primary differentiator.

One important caveat

I found several Chicago agencies advertising “headless Shopify,” but not all appear to have a genuinely local downtown presence. For example, Uncap is a strong Chicago Shopify/Platinum Partner with headless capability, but its current office is at 8770 W Bryn Mawr, near O'Hare rather than downtown. Shopify's directory confirms its Chicago presence and headless-commerce service. Shopify

For a startup founder, my first two calls would therefore be Praella and BlueBolt. Praella looks stronger for a polished, brand/UX-heavy Shopify Plus build; BlueBolt looks especially compelling if the architecture/integrations are going to be technically demanding.

What I'd ask in the first call

Don't just ask “Have you built headless Shopify?” Ask for:

1. 2–3 live Shopify Hydrogen/Next.js storefronts they built, preferably launched in the last 18–24 months.
2. Whether they recommend Hydrogen/Oxygen, Next.js/Vercel, or another architecture—and why.
3. Who actually writes the frontend code: senior in-house engineers or subcontractors.
4. Their experience with Shopify Markets, subscriptions, search, personalization, CMS integration, analytics and checkout extensibility.
5. Expected ongoing maintenance burden versus a high-performance Shopify 2.0 theme.
6. A realistic startup-budget estimate and what they would not build headless.

That last question is important: a good Shopify agency should be willing to tell you when headless isn't worth the added engineering and maintenance complexity.

If you tell me your rough budget (e.g. $50k, $100k, $200k+), product category, and whether you need CMS/ERP/PIM integrations, I can narrow this to the 3 best agencies and compare likely fit, strengths, weaknesses, and estimated project size.

That last question is important: a good Shopify agency should be willing to tell you when headless isn't worth the added engineering and maintenance complexity.

If you tell me your rough budget (e.g. $50k, $100k, $200k+), product category, and whether you need CMS/ERP/PIM integrations, I can narrow this to the 3 best agencies and compare likely fit, strengths, weaknesses, and estimated project size.

Yes. I’d narrow the field considerably: for a headless Shopify storefront, you want agencies that can demonstrate actual headless architecture—not just “Shopify development.”

My Chicago shortlist

1. Praella — best downtown fit
   • 203 N LaSalle St, Chicago, right in the Loop.
   • Shopify/Shopify Plus specialist with a Platinum-level Shopify partnership.
   • Strong candidate if you want a polished DTC storefront plus serious Shopify Plus engineering.
   • Their local presence makes them particularly interesting if you want to work with a Chicago team rather than a remote-only shop.

2. BlueBolt Solutions — strong technical/composable option
   • 415 N LaSalle Dr, River North.
   • Shopify Plus, custom development/integrations, and headless digital experience work are part of their offering.
   • I'd put them on the shortlist if your headless build involves a CMS, personalization, experimentation, or other composable components.

3. Atwix — strong engineering-heavy option
   • 20 N Wacker Dr, downtown.
   • More of a complex-commerce engineering firm than a boutique Shopify design agency. They work with Shopify/Shopify Plus and have extensive commerce-platform engineering experience.
   • Worth considering if your storefront needs substantial integrations or unusual backend requirements.

4. Americaneagle.com — enterprise-scale option
   • 200 W Jackson Blvd, Loop.
   • Downtown presence and significant enterprise commerce/digital experience capabilities.
   • Probably overkill for an early-stage startup unless you're already dealing with substantial catalog, integration, internationalization, or organizational complexity.

5. Nansen LLC — interesting composable-commerce option
   • 300 W Hubbard St, River North.
   • Their stack includes e-commerce, UX, optimization and modern frontend/composable technologies, including Vercel.
   • I'd investigate them if you're thinking beyond a conventional Shopify Hydrogen build.

One important non-downtown contender

Uncap is worth talking to even though it's not downtown. Shopify's own partner directory lists Uncap as a Platinum Partner and explicitly lists headless commerce among its services. www.shopify.com Their Chicago practice is particularly focused on Shopify Plus/B2B and complex integrations. www.uncap.com

How I'd rank them for a startup

My first three calls would be Praella, BlueBolt, and Uncap. For a startup, I'd be especially careful about choosing an agency whose economics and process are designed for enterprise clients; a technically excellent agency can still be a poor fit if your project is a $50–150K build rather than a $500K+ commerce transformation.

One other useful benchmark: agencies currently advertising Chicago headless Shopify work include WayOut, which explicitly lists Hydrogen/Next.js and says its headless builds start at $75K, and 100xelevate, which describes React/Hydrogen, Shopify Storefront API, Sanity/Contentful and related headless implementations. www.wayoutinc.com

If you tell me your rough budget (e.g. $50–100K vs. $100–250K), B2C vs. B2B, and whether you want Hydrogen or Next.js, I can narrow this to the 3 agencies I'd actually interview and give you the questions I'd use to vet their headless experience.

Yes. I found a fairly short list of downtown/central Chicago firms with credible headless-commerce signals, rather than just agencies that happen to build Shopify themes.

My shortlist

One notable Chicago Shopify specialist is Uncap, but I wouldn't put it in your "downtown" shortlist: its current Chicago office is at 8770 W Bryn Mawr. Shopify itself confirms that Uncap offers headless commerce and identifies it as a Platinum Partner. www.shopify.com

Who I'd talk to first

1. Praella — probably my first call. It's actually downtown, is a Shopify Platinum Partner, and explicitly lists headless commerce alongside Shopify Plus, custom apps, integrations, UX and conversion work. www.shopify.com

2. World Headquarters — particularly compelling if the storefront is a major part of your product differentiation. Their positioning is much closer to composable commerce / digital product architecture than "we'll customize your Shopify theme."

3. BlueBolt — I'd include them if your headless architecture has substantial integration/API requirements.

One other Chicago-area agency worth knowing about is Caxy. It's founder-led from Chicago and explicitly says it has shipped Shopify Plus headless implementations using modern commerce architecture, with senior US engineers. www.caxy.com

One thing I'd ask every agency

Don't just ask "Have you built headless Shopify?" Ask:

"Can you show me two production Shopify headless storefronts you personally architected, tell me why headless was chosen, what frontend framework you used, and who maintains the architecture today?"

That's important because "headless Shopify" can mean anything from a genuinely decoupled Hydrogen/Next.js + Storefront API architecture to a conventional Shopify theme with a few custom components.

For a startup, I'd also have them explain why you should go headless at all. If your primary need is speed to market, headless can add substantial frontend infrastructure, deployment, testing and maintenance overhead. If you need a highly differentiated experience, sophisticated content model, app-like UX, or integration with a broader product platform, it can be much more compelling.

If you tell me your approximate budget ($50k, $100k, $250k+), product category, and whether you're on Shopify Plus already, I can narrow this to the 3 Chicago agencies I'd actually put on your RFP list and compare their likely strengths/weaknesses.

Yes. I’d narrow the field quite a bit—“Shopify agency” and “headless Shopify agency” are not the same thing. For a startup specifically looking for a headless storefront, I’d prioritize firms that can show actual Hydrogen/Next.js or API-driven Shopify work.

My Chicago shortlist

1. Praella — best overall enterprise-capable option
   • Downtown office: 203 N LaSalle St.
   • Shopify Plus Platinum Partner with a substantial team.
   • Strong across UX/design, integrations, migrations and custom development. www.shopify.com
   • Caveat: Shopify's partner profile doesn't explicitly list “Headless commerce,” so I'd ask them for 2–3 recent headless references before shortlisting them specifically for this project.

2. Uncap — strongest technically verified headless fit
   • Shopify lists Uncap as a Platinum Partner in Chicago and explicitly lists Headless commerce among its services. www.shopify.com
   • Particularly compelling if your startup has complicated catalog, ERP, B2B/B2C or omnichannel requirements.
   • Location caveat: their Chicago office is at 8770 W Bryn Mawr, not downtown. Uncap

3. Buena Suerte — interesting boutique option
   • Chicago-based creative web-development practice.
   • Shopify lists Headless commerce explicitly, along with custom development and ongoing management. www.shopify.com
   • Their smaller/boutique positioning could be attractive if you're a startup that wants senior people directly involved rather than a large agency team.

4. Digital Lofts — smaller Shopify specialist
   • Chicago-based and explicitly lists Headless commerce.
   • Shopify describes 7+ years of experience and custom themes/apps. www.shopify.com
   • I'd put them in the “get a proposal and assess technical depth” bucket rather than assuming they're equivalent to a large Plus agency.

5. Makro — worth considering if you're already approaching enterprise scale
   • Markets directly to Chicago Shopify Plus merchants and lists Headless Commerce as a core capability alongside UX/UI, integrations, migrations and CRO. www.makroagency.com
   • More enterprise-oriented than startup-oriented, so I'd ask about minimum project size and whether you'd get senior engineering attention.

One downtown agency I'd investigate carefully

BlueBolt Solutions is at 415 N LaSalle Dr and has Shopify/Shopify Plus expertise plus headless digital-experience capabilities. However, its public positioning spans several commerce platforms, so I'd want to see specific Shopify headless case studies before putting it ahead of the specialists.

Who I'd contact first

For a startup, my initial three would be:

One important distinction: don't let an agency sell you “headless” merely because they're comfortable with Shopify APIs. For your RFP, I'd specifically ask whether they've shipped production storefronts using Shopify Hydrogen + Oxygen, Next.js + Shopify Storefront API, or another composable architecture, and ask for URLs to live examples.

If you tell me your rough annual revenue/GMV, product count, whether you're B2C or B2B, and whether you already have a CMS (Sanity, Contentful, etc.), I can narrow this to 3 agencies and compare likely project cost, technical fit, and relevant case studies.

For a startup founder, I’d separate “Shopify agencies in Chicago” from agencies that can actually handle a headless build (custom frontend, APIs, CMS, performance, integrations). A few Chicago-area firms that appear relevant:

A few questions I’d ask each agency before signing:

1. Show me 2–3 live headless Shopify stores you shipped (not just Shopify themes).
2. What frontend stack do you recommend? (Hydrogen, Next.js, Remix, custom React, etc.)
3. Who owns the architecture decisions? (senior engineer vs. project manager)
4. How do you handle Shopify checkout limitations?
5. What CMS do you pair with Shopify? (Sanity, Contentful, Shopify metaobjects, etc.)
6. What happens after launch? (performance monitoring, CRO, feature roadmap)

For a venture-backed or fast-growing startup, I’d probably shortlist:

• Caxy if engineering complexity is high.
• Roboto Studio if the differentiator is brand experience/design.
• Praella or Uncap if you need a Shopify-native partner with operational depth.
• BlueBolt if content, personalization, and commerce are intertwined.

One caveat: “downtown Chicago” narrows the pool a lot; some of the strongest Shopify specialists are Chicago-based but not necessarily Loop offices. If you want, I can also make a shortlist ranked by startup fit, estimated budget tier, and likely project size ($50k vs $150k+ builds).

Yes. I’d narrow the field considerably if “downtown Chicago” + proven Shopify headless experience are both requirements. I found a handful worth putting on an RFP list:

One I'd especially investigate: Atwix

Atwix is probably the most obvious fit if you're building something technically sophisticated rather than just wanting a beautiful Shopify redesign. Its Chicago office is at 20 N Wacker, and it explicitly says it builds custom Shopify Plus headless storefronts, alongside ERP/CRM integrations and custom development. www.atwix.com

1Digital is another strong candidate

1Digital Agency has unusually explicit current documentation around Hydrogen + Oxygen, React, Shopify Storefront API, and headless Next.js storefronts. It says it has 50+ specialists and 400+ brands, and lists engagements starting at $185/hour. www.1digitalagency.comwww.1digitalagency.com

For a startup, I'd ask them to price both a Hydrogen/Oxygen implementation and a conventional Shopify 2.0 build. Their own materials acknowledge that headless isn't automatically the right answer, which is a good sign. www.1digitalagency.comwww.1digitalagency.com

I'd also look just outside your “downtown” constraint

If you're willing to work with a Chicago-area agency rather than requiring a downtown office, the pool gets more interesting. Uncap is a Chicago Shopify Platinum Partner that explicitly lists headless commerce among its services. www.shopify.com

And Caxy is particularly interesting for a startup with a technically ambitious product: it's Chicago-founded, has 40+ senior US engineers, and explicitly cites production experience with Shopify Plus headless, React and modern commerce architectures. Its Chicago HQ is at 212 W Van Buren. www.caxy.com

My suggested shortlist

If I were the founder making the calls, I'd start with:

1. Atwix — technical/enterprise headless
2. 1Digital — Shopify Plus + Hydrogen, broader growth capabilities
3. Praella — Shopify-native agency with a downtown Chicago presence
4. Caxy — if your architecture/integrations are unusually complex
5. Uncap — if you can relax the downtown-office requirement

One important caveat: “we can build headless” isn't the same as “we've successfully shipped several Shopify headless stores.” In your first call, I'd specifically ask each agency for 2–3 live Shopify Hydrogen/Next.js storefronts they personally built, the Shopify backend architecture, CMS choice, and what their team—not a subcontractor—actually owned.

If you tell me your rough budget (e.g. <$75k, $75–150k, $150k+) and what you're selling, I can narrow these to the best 3 agencies for a startup and compare likely fit, technical stack, pricing, and relevant case studies.

Yes. I’d narrow the field considerably if headless Shopify is the requirement rather than just “Shopify development.”

Downtown Chicago shortlist

1. Praella - eCommerce Agency — 203 N LaSalle St
   • Probably the first one I’d interview for a startup.
   • Shopify/Shopify Plus is a core specialization, rather than a small part of a broader digital-agency offering.
   • Strong fit if you want Shopify Plus plus custom engineering and integrations.
   • Ask specifically: for 2–3 recent headless builds using Hydrogen/Next.js and whether the work was done by their in-house team.

2. BlueBolt Solutions — 415 N LaSalle Dr
   • Very relevant Shopify/Shopify Plus background and downtown location.
   • Their positioning emphasizes custom Shopify development, migrations, integrations and ongoing support.
   • I'd put them on the shortlist, but verify recent production headless work rather than assuming Shopify Plus experience means headless experience.

3. Atwix — 20 N Wacker Dr
   • Downtown and highly technical, with extensive commerce-engineering experience.
   • Their historical strength is Adobe Commerce/Magento, but they also work with Shopify/Shopify Plus.
   • More interesting if your storefront needs complicated ERP/PIM/CRM or other backend integrations than if you're primarily looking for a lean startup storefront build.

4. Kin + Carta — 111 N Canal St
   • Very close to the heart of downtown and capable of serious product/engineering work.
   • However, I'd view them more as a digital-product/enterprise engineering consultancy than a Shopify specialist. The economics and process may also be heavier than what a startup needs.

One Chicago-area agency I'd add despite not being downtown

Makro looks particularly interesting for your specific requirement. Its Chicago practice explicitly lists Headless Commerce alongside Shopify Plus, ecommerce development, UX/UI and platform migration. It says it focuses exclusively on Shopify Plus and has experience with complex retail and B2B commerce. www.makroagency.com

That's a stronger public signal of actual headless specialization than I found for several downtown agencies.

I'd also not put Orbit Media at the top of this particular list. Orbit Media Studios has a strong Chicago presence and substantial Shopify/web-development experience, but its published Shopify offering emphasizes custom Shopify sites/themes, UX, SEO and CRO rather than explicitly positioning itself as a headless Shopify specialist. www.orbitmedia.com

My suggested interview order

Makro → Praella → BlueBolt → Atwix → Kin + Carta

For a startup, I'd evaluate them on headless Shopify experience, not simply Shopify Plus credentials. In the first call, ask:

• “Show me three live headless Shopify stores you built, and tell me what frontend architecture each uses.”
• “Are you recommending Hydrogen/Oxygen, Next.js/Vercel, or something else—and why?”
• “How do you handle Shopify checkout, subscriptions, search, CMS/content, analytics and preview environments?”
• “What percentage of the implementation is done by your own engineers?”
• “What will we need to maintain after launch?”
• “Give me a realistic build range and timeline for a startup of our size.”

One particularly useful distinction: Bounteous has very substantial Shopify Plus experience and is a Chicago-based commerce consultancy, including complex enterprise implementations, but its Chicago office is in Ravenswood rather than downtown. www.bounteous.com If you're willing to go beyond downtown, it's worth considering for a much larger/complex build.

If you tell me your rough budget (e.g. $50k, $100k, $250k+) and whether you're thinking Hydrogen or Next.js, I can narrow this to the 3 agencies I'd actually take into an RFP.

Yes. I’d narrow the field pretty aggressively, because “Shopify agency” and actual headless Shopify experience are very different things.

My Chicago shortlist

1. Praella — 203 N LaSalle St, Loop
   • Strongest obvious downtown fit.
   • Shopify/Shopify Plus specialist and Platinum Shopify Partner.
   • Worth interviewing if you want a Shopify-native agency that can handle strategy, UX, implementation and ongoing optimization.
   • I’d specifically ask them to show recent production headless storefronts, rather than accepting general Shopify case studies.

2. BlueBolt Solutions — 415 N LaSalle Dr
   • Downtown Chicago and focused on more technically complex ecommerce.
   • Shopify Plus, custom development, integrations and platform migrations are core capabilities.
   • Particularly interesting if your headless build has significant ERP/PIM/CRM integration requirements.

3. World Headquarters — 24 E Washington St
   • One of the more interesting options if your storefront needs to be composable/headless, rather than simply a customized Shopify theme.
   • Their capabilities explicitly include composable/headless commerce, product configurators, product data, B2B/B2C and complex product experiences.

4. Americaneagle.com, Inc. — 200 W Jackson Blvd
   • Much larger enterprise-oriented shop.
   • Better candidate if you're anticipating complex integrations, substantial traffic/catalog scale, international commerce, or an enterprise-grade implementation process.
   • I'd expect it to be a considerably different engagement from a startup-oriented boutique.

5. Atwix — 20 N Wacker Dr
   • Downtown and deeply technical/commerce-oriented.
   • Their primary heritage is Adobe Commerce/Magento rather than Shopify, so I'd rank them behind the first three for a Shopify-first startup—but potentially ahead of them if your project is integration-heavy.

One agency I'd consider even though it isn't downtown

Uncap is Chicago-based and a Shopify Platinum Partner. Shopify's partner directory explicitly lists headless commerce among its services, alongside Shopify/Shopify Plus builds, migrations and optimization. www.shopify.com

There's also Makro, which has a particularly clear Shopify Plus/headless positioning and publishes substantial Shopify case-study material. Its Chicago practice explicitly lists Headless Commerce alongside Shopify Plus, B2B, custom apps and integrations. www.makroagency.com

If I were your founder, I'd interview 3

I'd start with:

Praella → World Headquarters → BlueBolt

Then add Uncap or Makro as the fourth bid if you want a benchmark from a Shopify-specialist agency.

The key question isn't “Can you build headless Shopify?” Nearly everyone will say yes. Ask each agency:

• Show me 2–3 live Shopify headless stores you personally built.
• Are they using Hydrogen/Oxygen, Next.js/Vercel, or something else?
• Who owns the frontend code and infrastructure?
• What CMS do they recommend—Shopify, Sanity, Contentful, etc.—and why?
• What happens to Shopify checkout, customer accounts, subscriptions and promotions?
• How do they handle preview/staging and merchandising?
• What's their expected ongoing engineering cost after launch?
• Why should we go headless instead of a very well-built Shopify 2.0 theme?

That last question is especially important for a startup. Headless can give you a much better UX and architectural flexibility, but it also creates another software system that you'll need to maintain.

If you tell me roughly your product category, expected GMV/traffic, integrations (ERP/PIM/CRM), and whether you're Shopify Plus, I can narrow this to the 3 agencies I'd actually put on the RFP and compare their likely strengths, weaknesses and fit.

Yes. I found a few downtown/central Chicago agencies with credible evidence of Shopify headless experience. I’d put these at the top of your shortlist:

My ranking for a startup founder

1. Praella — probably the first call I'd make if you're primarily looking for a Shopify-focused agency that can own the whole storefront experience. Their published work specifically identifies headless/PWA and Hydrogen projects, and their North American team is headquartered in Chicago. praella.compraella.com

2. Caxy — I'd choose them over a traditional Shopify agency if your architecture is going to be unusually technical. They explicitly advertise Shopify Plus headless, have senior US engineers, and are at 212 W Van Buren. They also publish a $50K minimum engagement / $150K–$500K typical project range, which is useful for early qualification. www.caxy.com

3. Codal — worth including if brand/design and customer experience are as important as the underlying architecture. Their West Loop office is close to downtown and they advertise both Shopify and headless/composable commerce.

One caveat: I wouldn't select an agency merely because it says "headless." For a Shopify build, I'd ask each finalist for 2–3 live Shopify Hydrogen/Next.js storefronts, their approach to Storefront API, CMS, search, analytics, checkout, preview environments and hosting, and the actual engineers who would work on your project.

If you tell me your rough budget (e.g. $50–100K vs. $150–300K), product category, and whether you're on Shopify Plus, I can narrow this to the 3 best agencies for your specific startup and compare their likely strengths, pricing and relevant case studies.

Yes. I’d narrow the downtown/central Chicago field to four agencies worth putting on an RFP shortlist, with two especially strong fits for a startup.

My first three calls

1. Codal — probably the first agency I'd interview. They're a Chicago-based Shopify Platinum Partner and explicitly describe Hydrogen/headless implementation, rather than merely saying they "do Shopify." Their portfolio also includes a unified headless eCommerce project. www.shopify.com

2. Praella — particularly attractive if you want a Shopify-native agency rather than a general software consultancy. They're a Shopify Platinum Partner, have their North American headquarters in Chicago, and have extensive Shopify Plus work. www.shopify.com

3. Caxy — I'd put them on the RFP if your headless build is technically ambitious. They explicitly advertise Shopify Plus headless, React/Node/AWS engineering, and integrations with systems such as NetSuite, SAP and Salesforce. Their published project range is roughly $150K–$500K, so they're likely a better fit for a well-funded startup than a shoestring MVP. www.caxy.com

One important caveat

I wouldn't select an agency simply because it says "headless." For a startup, I'd ask each candidate for:

• 2–3 live Shopify Hydrogen/Next.js stores they personally built
• The client and launch date for each
• Whether they used Hydrogen + Oxygen, Hydrogen + Vercel, or Next.js
• What CMS they paired with Shopify — Sanity, Contentful, Shopify metaobjects, etc.
• Who owns the code and infrastructure after launch
• Their approach to SEO, redirects, analytics, checkout, subscriptions and Shopify Functions
• A realistic 12-month total cost, including post-launch support
• A reference from a company roughly your size, not just a $100M enterprise

For a startup, I'd be especially wary of an agency proposing headless merely because it's technically interesting. Headless adds considerable engineering and maintenance overhead; the agency should be able to explain why the business case justifies it versus a highly customized Shopify theme.

If you tell me your approximate budget (e.g. $50–100K, $100–250K, $250K+) and whether you're B2C, B2B, or both, I can narrow these down to the 2–3 agencies I'd actually invite to pitch, including relevant case studies and estimated fit.

Yes. I’d narrow the downtown-Chicago field quite a bit rather than treating every Shopify agency as a headless specialist.

My shortlist

One particularly interesting option is Praella. Its public portfolio specifically tags projects as “headless / PWA” and “Shopify Hydrogen build,” and the firm says its North American team is headquartered in Chicago. praella.com

Caxy is the other one I'd take seriously if your storefront isn't just a marketing-heavy DTC site. They explicitly advertise Shopify Plus headless and have substantial experience integrating commerce with CMS/CRM/ERP systems. Their published project range is roughly $150K–$500K, with engagements starting around $50K, so they're likely a better fit once the startup has meaningful technical/commerce complexity. www.caxy.com

One important distinction

If by “headless Shopify” you specifically mean Shopify Hydrogen + Oxygen, I'd put Praella and Caxy at the top of the interview list. If you're open to Next.js + Shopify Storefront API + a headless CMS such as Sanity, Caxy becomes particularly interesting.

I would also look beyond downtown if you're willing to do a Chicago-based rather than strictly downtown search. For example, Uncap is a Chicago Shopify Platinum Partner with headless commerce listed among its services, although its current office is near O'Hare rather than downtown. www.shopify.com

If you tell me your rough budget ($50–100K, $100–250K, $250K+) and whether you're DTC, B2B, or both, I can narrow this to 3 agencies and compare their headless case studies, likely project fit, and pricing/engagement model.

Yes. I’d narrow the field considerably if “downtown Chicago + proven headless Shopify” are hard requirements.

My shortlist

Codal is the clearest match I found: its Shopify practice specifically highlights “Unified headless eCommerce for Cosori and its sister brands,” and its Chicago office is at 433 W. Van Buren. Shopify also lists Codal as a Platinum Partner. codal.com

Praella is at 203 N. LaSalle St., squarely downtown, and Shopify lists its primary location as Chicago and its tier as Platinum. praella.com

Caxy is particularly interesting if your storefront is only part of a larger technical architecture. It advertises Shopify Plus headless alongside Salesforce Commerce Cloud, BigCommerce and commercetools, and says its team has 20+ years of production ecommerce experience. Its Chicago HQ is at 212 W. Van Buren. praella.comwww.caxy.com

One I would not count as downtown

Uncap is a legitimate Shopify headless-capable agency and Shopify Platinum Partner, but its Chicago HQ is at 8770 W. Bryn Mawr Ave., near O'Hare rather than downtown. Shopify explicitly lists Headless Commerce among its services. www.shopify.com

If I were the founder

I'd take Codal, Praella, and Caxy into a first-round conversation.

I'd ask each for:

1. 2–3 live Shopify headless storefronts they've built—not just Shopify theme work.
2. The exact architecture: Hydrogen vs. Next.js, Shopify Oxygen vs. Vercel, CMS choice, search, subscriptions, etc.
3. Who actually does the engineering and whether it's in-house.
4. A realistic v1 launch timeline and budget.
5. What they would not make headless. A good agency should be willing to tell you when headless is unnecessary.
6. How they handle Shopify checkout, analytics, SEO, redirects, preview environments, and ongoing merchandising.

For a startup, I'd put particular weight on senior engineering involvement and speed of iteration, rather than simply choosing the biggest Shopify agency.

If you tell me your approximate budget (e.g. $50k, $100k, $250k+) and product/catalog complexity, I can rank these agencies specifically for your situation and dig up their relevant headless case studies.

Yes. I’d narrow the field quite a bit if “downtown Chicago” + real headless Shopify experience are both requirements.

My shortlist

Praella stands out most clearly. Its project portfolio explicitly includes categories for “headless / PWA” and “Shopify Hydrogen build,” and Shopify's partner directory identifies Praella as a Chicago-based Platinum Partner. praella.com Its North American team is headquartered in Chicago. praella.com

Praella

For a startup, I'd probably start with Praella and BlueBolt, then use Americaneagle.com as a benchmark if your architecture/integrations are unusually complex.

One important caveat

There are other agencies marketing headless Shopify to Chicago, but they're not actually downtown. For example, Uncap is a legitimate Chicago Shopify/Shopify Plus agency and Shopify's directory specifically lists headless commerce among its services, but its office is at 8770 W Bryn Mawr, near O'Hare—not downtown. www.shopify.com

Likewise, Makro explicitly offers headless commerce and Shopify Plus, but I wouldn't classify it as a downtown-Chicago agency based on the evidence I found. www.makroagency.com

What I'd ask agencies before signing

For a headless build, don't settle for “yes, we do headless.” Ask for:

1. 2–3 live Shopify Hydrogen storefronts they've actually launched
2. The GitHub/architecture-level stack: Hydrogen, Oxygen/Vercel, Sanity/Contentful, search, subscriptions, etc.
3. Who will actually write the frontend code and whether they're in-house
4. How they handle Shopify checkout, cart, customer accounts and app compatibility in a headless architecture
5. Their approach to SEO, Core Web Vitals, analytics and merchandising
6. A realistic post-launch engineering/support model
7. Whether they'd recommend headless for your business—or tell you that Shopify's native storefront would be smarter

That last question is particularly important: a good agency should be willing to tell you not to go headless if the added complexity isn't justified.

If you tell me roughly your funding/revenue stage, product category, expected SKU count, and why you want headless, I can narrow this to the 3 agencies I'd actually interview and what each should cost.
