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.

• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States

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.

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.
