ChatGPT answers, unedited

For a Chicago startup, I’d bias toward agencies that can think like a product team—not just build a marketing site. For a headless CMS + developer-friendly MVP architecture, the key things I’d look for are:

• React/Next.js or similar modern frontend experience
• API-first CMS experience (Contentful, Sanity, Strapi, Payload, headless WordPress, etc.)
• clean repo ownership and documentation
• cloud/deployment experience (Vercel, AWS, CI/CD)
• ability to iterate after MVP rather than disappear after launch

My shortlist:

A few smaller studios that may fit a leaner startup budget:

• Nous Frame — modern stack, custom builds, and headless CMS positioning; likely better for polished marketing sites and content platforms than deeply complex SaaS products. nousframe.com
• Legible Studio — emphasizes Next.js, React, TypeScript, and CMS ownership/handoff; interesting for startups that want clean frontend architecture. legible.studio
• Adam Culpepper — a good option if you already have backend/product direction and need senior frontend + headless CMS integration help. adamculpepper.net

My rough recommendations by startup stage:

Pre-seed / validating an idea

1. 8th Light
2. TXI
3. TUPA Dev
4. Eight Bit Studios

Seed stage with a defined product

1. Codal
2. 8th Light
3. TXI

Marketing site + content platform using headless CMS

1. Nous Frame
2. Legible Studio
3. One North

When interviewing them, I’d ask:

1. “Show me a recent project using Next.js + a headless CMS.”
2. “Who owns the GitHub repo and cloud accounts at the end?”
3. “What would your MVP architecture look like if we had 10,000 users vs. 1 million?”
4. “Which parts would you intentionally not build in v1?”
5. “Can you introduce us to a founder you built an MVP for?”

For a startup specifically, I’d avoid agencies that pitch a beautiful Figma prototype but cannot explain data models, APIs, deployment, testing, and how the product evolves after launch.

Yes. For a startup, I’d bias toward agencies that can architect the product and CMS, not just produce a polished marketing site. In Chicago, my shortlist would be:

My top picks

1. Reach Creative — best overall fit

• Particularly strong if you want Next.js/React + headless CMS + good product/design work.
• Their Prismic partner profile lists Next.js, React, Node, TypeScript, GraphQL, Vercel and AWS, and they have documented work with Prismic. Prismic
• Developer experience looks unusually credible: their engineering team has worked with Prismic, Sanity, and Strapi, as well as Next.js. Karly Hoffman
• I'd call them first for a startup that wants a sophisticated MVP without creating a maintenance nightmare.
• Vault Innovation — best for an actual product/MVP

• More software/product-oriented than a conventional web agency.
• They explicitly work with founders and small teams on MVPs, full-stack web applications and SaaS-style products. Techreviewer
• I'd favor them if your "website" is really the first version of a web application/product, with authentication, APIs, payments, dashboards, etc.
• I'd specifically ask them whether they'd use Payload/Sanity + Next.js rather than defaulting to a conventional CMS.
• Doejo — best startup/design + engineering combination

• Chicago-based and explicitly oriented toward startups, apps, platforms and custom development. BigCommerce Partner Program
• Good choice if brand, UX and MVP engineering need to happen together.
• Caveat: their public profiles lean heavily toward WordPress, so I'd make headless architecture a requirement in the RFP rather than assuming they'll recommend it. Clutch
• Clique Studios — best if you're expecting to grow into a larger organization

• Strong Chicago digital-product/design shop with substantial engineering capability.
• They explicitly support Contentful, headless CMS platforms and custom applications, with documented version-control, staging and QA practices. Clique Studios
• They also offer headless WordPress with React/Next.js/Vue frontends. Clique Studios
• My hesitation is that they're probably more agency than an early-stage startup needs if you're trying to get a lean MVP out for $30–75k.
• Plego Technologies — good engineering-heavy alternative

• They do both CMS-driven websites and considerably more substantial custom web applications/SaaS-style work.
• I'd consider them if the MVP needs backend integrations and application functionality beyond a content-heavy website.

How I'd rank them for your specific use case

The architecture I'd ask them to propose

For a new startup in 2026, I'd ask each agency to price the MVP around something like:

Next.js + TypeScript → Sanity or Payload → Postgres where needed → Vercel/AWS → API integrations

I'm particularly interested in Sanity vs. Payload rather than simply asking for "a headless CMS." Sanity is very strong for developer-led structured content and Next.js, while Payload is compelling when you want the CMS and application/backend closer together and want self-hosting/control. Sanity.io Nayan Kyada

I'd avoid letting an agency turn a relatively simple MVP into a Next.js + Contentful + custom backend + microservices + Kubernetes architecture. The MVP should have clear seams for future growth without prematurely distributing everything.

One important screening question

When interviewing agencies, I'd ask:

"Show me the architecture diagram you'd use for our MVP, what you'd deliberately not build yet, and how you'd expect us to replace your agency with an internal engineering team in 12–18 months."

That question will separate a genuinely developer-friendly product shop from an agency optimizing for a large initial project.

If you give me your rough startup type, MVP budget (e.g. $25k/$50k/$100k+), and whether it's primarily a marketing site or an actual SaaS/web app, I can narrow this to 2–3 Chicago firms and tell you exactly what I'd ask each to quote.

• TXI - 10 S Riverside Plaza Ste 875 - #7670, Chicago, IL 60606, United States
• Vault Innovation - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• Adage Technologies - 10 S Riverside Plaza Ste 1500, Chicago, IL 60606, United States
• Clique Studios - 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
• One North, A TEKsystems Company - 227 W Monroe St #3500, Chicago, IL 60606, United States

• CodingCops - 1 E Erie St, Chicago, IL 60611, United States
• Solid Digital - 100 N LaSalle St #1400, Chicago, IL 60602, United States

Yes. For a startup, I’d optimize for engineering quality + speed of iteration, not a traditional “web design agency.” The ideal partner should be comfortable handing you a clean repo, typed APIs, CI/CD, a sensible CMS schema, and an architecture your eventual internal engineers can take over.

My Chicago shortlist

• Nous Frame — best fit for a small startup/product team.

Chicago-based, focused on custom web/software work, with React and explicit Sanity/Storyblok headless CMS experience. Their smaller-studio profile makes them particularly interesting if you want senior people actually doing the implementation rather than a large agency team.

• TXI — best for a serious MVP that may become a product.

TXI is more of a digital-product consultancy than a conventional web agency. I'd consider them if the “MVP” includes meaningful product logic, user workflows, data architecture, or integrations—not just a marketing site.

• Vault Innovation — good startup/MVP-oriented option.

They explicitly work on custom software and MVPs, including full-stack web applications. I'd shortlist them if the CMS is only one component of a broader product build.

• Adage Technologies — stronger choice for a more sophisticated build.

They're a Chicago software/product firm rather than purely a design shop, with CMS/DXP implementation and custom software capabilities. Probably overkill for a very small MVP, but attractive if you're expecting integrations, complex content workflows, or enterprise customers.

• Clique Studios — good if brand/design matters almost as much as engineering.

Their Chicago team combines strategy, design, engineering and CMS work, including Contentful. I'd favor them for a startup where the public-facing experience and brand are major parts of the product launch.

• One North, A TEKsystems Company — enterprise-oriented alternative.

They do headless CMS, application development and CMS migrations, but I'd generally put them below the smaller firms for an early-stage startup unless you already have substantial budget and enterprise requirements.

One important caveat

I wouldn't automatically choose an agency simply because it says “headless CMS.” For an MVP, headless can actually be unnecessary complexity. The architecture should earn its complexity.

For example, a pretty sensible startup stack might be:

Next.js + TypeScript → Sanity → Postgres/Supabase → Vercel

or, if you need more ownership/control:

Next.js + TypeScript → Payload/Strapi → Postgres → Vercel/AWS

Sanity, Strapi, Contentful and Payload are all being used in current headless builds, but their tradeoffs are quite different. Kultrix Creaytic

I'd also look beyond Chicago proper if technical quality is the priority. There are specialists such as Otterdev, which explicitly focuses on Sanity/Contentful/Strapi + Next.js/Astro, and Kultrix, which specifically advertises startup MVP engagements alongside Sanity/Strapi/Contentful/Next.js. OtterDev Kultrix

My ranking for your specific brief

If I were a technical founder, I'd interview Nous Frame, TXI, and Vault Innovation first, then ask each to propose the architecture before deciding on the CMS.

The interview question I'd use is:

“We're optimizing for a 3–6 month MVP, eventual internal engineering ownership, and minimal rewrite risk. Show us how you'd structure the Next.js app, CMS schemas, API/data layer, environments, testing, CI/CD, and handoff—and tell us what you deliberately would not build yet.”

The agency that gives you the simplest credible architecture, rather than the most elaborate one, is probably the one I'd hire.

Yes. For a startup that wants a headless CMS plus an MVP architecture that another engineering team can inherit, I’d favor product/engineering-oriented shops over traditional branding-heavy web agencies.

My Chicago shortlist

1. Reach Creative — strongest fit for a polished startup product
   • Chicago-based and explicitly works with Next.js, React, Node.js, TypeScript, GraphQL and Vercel.
   • Their public profile also cites Prismic headless CMS work.
   • I’d consider them if the MVP needs to feel highly designed while still being a real React/Next.js application.

2. Nous Frame — interesting smaller-studio option
   • Specifically describes headless CMS integrations with Sanity and Storyblok, alongside React.
   • Their process includes CMS integration during implementation rather than treating the CMS as an afterthought.
   • This is probably the kind of smaller, hands-on shop I'd investigate first if you want direct access to the developers.

3. TXI — best if the "MVP" is actually a product
   • More of a digital-product consultancy than a conventional web agency.
   • Strong fit when you need product discovery → architecture → UX → engineering, particularly if the eventual product is substantially more complicated than a marketing site.
   • I'd shortlist them for a startup where you're trying to avoid throwing away the MVP six months later.

4. LaunchPad Lab — strong engineering/product option
   • Chicago product-development consultancy with experience across React, Node.js and Contentful.
   • More appropriate if your MVP involves integrations, authenticated experiences, SaaS functionality, or a substantial backend rather than simply a headless marketing site.

5. Dom & Tom — bigger-team option
   • End-to-end product strategy, design and full-stack engineering, with a Chicago office.
   • Good candidate if you want a fairly substantial team rather than a boutique studio.

6. DIESELHAUS — worth considering for custom software + CMS
   • Does both web applications and CMS work, including headless approaches.
   • I'd put them behind the first few for a developer-first headless architecture, but they're worth talking to if the MVP has significant custom application functionality.

One non-Chicago agency I'd seriously consider

Lucky Media is worth putting on the comparison list even though it isn't a Chicago-local shop. Its current offering is unusually aligned with your requirements: Next.js MVP development + headless CMS + Sanity/Contentful + ISR, and Contentful lists them as a solution partner experienced with venture-backed startups. www.luckymedia.dev

What I'd ask them to build

For a developer-friendly startup MVP, I'd probably start conversations around:

Next.js + TypeScript + Sanity or Payload + Postgres + Vercel, with the CMS limited to genuinely editorial content.

Sanity is particularly attractive when engineers own the content model because its schemas are code-defined and version-controlled. Payload is worth considering when you want the CMS to live very close to the application itself. www.sanity.io

The important part isn't just "do you do headless CMS?" I'd ask each agency:

• Can our engineers own the GitHub repo and infrastructure?
• Is the CMS schema defined in code and committed to Git?
• Can we replace the agency without rewriting the application?
• Do you separate content data from product/business data?
• How do you handle preview/draft/publish?
• What's the testing strategy for the MVP?
• Can you give us a documented architecture diagram and local-development setup?
• Which parts are intentionally disposable MVP code vs. designed for production?
• Can you demonstrate a real Next.js + headless CMS project they've shipped, rather than a generic CMS site?

My first three calls would be Reach Creative, Nous Frame, and TXI, with Lucky Media as the outside-Chicago benchmark. The right choice depends heavily on whether your "MVP" is primarily a marketing/content experience or an actual SaaS/product application.

Yes. For a startup, I’d bias toward small senior engineering/product teams, not traditional Chicago “web design” agencies. You want someone who can make the CMS choice and leave you with an architecture your eventual in-house engineers won’t hate.

My Chicago shortlist

1. TXI — best for a true product/MVP architecture
   • Strongest choice if this is more than a marketing site and you expect the MVP to evolve into a real product.
   • They combine product discovery, UX, architecture and software engineering rather than treating the CMS as the whole project.
   • I'd ask them specifically about a Next.js + Sanity/Payload + API/backend separation for your use case.

2. Vault Innovation — best for startup MVP execution
   • Their positioning is much closer to “build the actual MVP” than “redesign your website.”
   • Particularly interesting if the CMS-backed site will eventually connect to a web application, accounts, payments, or other product functionality.

3. Reach Creative — best smaller web-focused option
   • Chicago digital/development studio with headless CMS experience, including Prismic.
   • Worth considering if the project is primarily a sophisticated marketing/product site rather than a full SaaS application.

4. Clique Studios — good if design + engineering both matter
   • Larger than the boutique options above, with strategy, design and engineering under one roof.
   • They work with Contentful and modern CMS approaches, so I'd consider them if brand/UX is a significant part of the MVP.

5. One North, A TEKsystems Company — technically capable, but probably overkill
   • Strong CMS/headless and digital-experience capabilities.
   • I'd look here for a better-funded startup with complicated enterprise integrations, not a lean $30–100k MVP.

One non-Chicago option I'd seriously consider

Lucky Media is worth putting on the list even though it isn't a Chicago-local agency. They're unusually explicit about Next.js + headless CMS, and specifically work with Sanity, Contentful and Storyblok. Their published work includes Next.js/headless projects for companies such as ServiceNow and Chainguard. www.luckymedia.dev

For your particular requirement, I actually think their specialization is more relevant than simply having a Chicago office.

What I'd ask each agency

Don't just ask “Do you do headless CMS?” Ask them to propose an architecture for:

Next.js + [Sanity/Payload/etc.] + TypeScript + Vercel + API/backend + Postgres

and then ask:

• Who owns the content model?
• Can we export/migrate all CMS content later?
• What belongs in the CMS vs. the application database?
• How do you handle preview/drafts?
• What does the repo architecture look like?
• Are we getting a modular component system or a pile of page-specific components?
• Can our engineers take over without you?
• What's the testing/CI/CD setup?
• What happens when the MVP needs authentication, payments, search, or a mobile client?
• How much of the architecture is actually custom versus an agency starter/template?

That last question is especially important. A startup should avoid an agency that builds a beautiful website architecture when what you really need is a product architecture.

My ranking for your use case

One important distinction: if this is a marketing site for a startup, I'd choose a headless specialist; if it's the first version of the actual startup product, I'd choose a product engineering firm. Those are surprisingly different agency searches.

For a developer-friendly startup stack in 2026, Next.js + Sanity is a particularly sensible default; Sanity has an official Next.js integration and supports server rendering, ISR and React Server Components. www.sanity.io Payload is another interesting option when you want the CMS much closer to the application/codebase itself. www.luckymedia.dev

If you tell me your approximate budget (e.g. <$30k, $30–75k, $75–150k), whether this is a marketing site or actual product, and preferred stack, I can narrow this to 3 agencies I'd actually interview, including likely fit and red flags.

Yes. For a startup that specifically wants headless CMS + developer-friendly MVP architecture, I’d narrow the Chicago market considerably rather than choosing a generic “web design agency.”

My shortlist

1. Thirdwave — strongest fit for maintainable web/CMS architecture
   • Chicago-based, with a strong full-stack orientation.
   • Their work emphasizes maintainable/scalable web platforms, CMS customization, integrations, and information architecture.
   • I’d consider them if you expect the marketing site to eventually become part of a larger product ecosystem.

2. Clique Studios — best balance of product design + engineering
   • Particularly interesting if you need UX/product thinking alongside engineering.
   • Their engineering offering covers custom development, APIs/integrations, CMS implementation, QA, and platforms including Contentful.
   • Better fit than a purely visual agency if your MVP has meaningful application logic.

3. TXI — best for a genuine software MVP
   • This is the one I'd investigate if “MVP architecture” means actual product architecture, not simply a startup website.
   • TXI positions itself around strategy, product discovery, design, and engineering, with an emphasis on evolutionary/maintainable architecture.
   • Likely more expensive than a small web studio, but potentially much better if you're building something investors/customers will actually use.

4. DIESELHAUS — good smaller-team option
   • Their capabilities span web/mobile applications and CMS work, including headless approaches and custom CMS development.
   • Worth talking to if you want one team to handle the website and application development without jumping immediately to a large consultancy.

5. Plego Technologies — pragmatic full-stack/MVP option
   • They do custom web applications, SaaS-style products, CMS builds, and broader software development.
   • I'd put them on the list if the MVP has substantial backend/API requirements rather than being primarily a content-driven site.

One wildcard

ParallelHQ is worth a look for a more startup/product-design-oriented engagement. Their Chicago practice explicitly advertises React, Next.js and headless CMS development, alongside UX/product strategy. www.parallelhq.com

And Brightter is interesting if you want a startup-oriented discovery → architecture → build process. They describe React/Next.js, Node, PostgreSQL/Supabase, API-first architecture, component systems, CI/CD, and rapid MVP discovery. www.brightter.com

How I'd rank them for your particular brief

One thing I'd be careful about: don't let an agency sell you “headless” simply because they're using Next.js. For an MVP, I'd want them to explain the content model, CMS choice, API boundaries, deployment architecture, authentication, database ownership, testing strategy, and how you'd replace the agency later.

For example, a sensible setup might be Next.js + TypeScript + a genuinely headless CMS (Contentful/Sanity/Strapi/etc.) + Postgres/Supabase + Vercel/AWS, but the right architecture depends heavily on whether you're building a content-heavy SaaS, marketplace, B2B application, or primarily a marketing site.

If you tell me what the startup actually does and roughly what the MVP needs to contain, I can narrow this to 3 Chicago agencies I'd interview first, including likely budget/engagement style and what I'd ask each one in the first call.

For a startup MVP where the website is part of the product—not just a marketing site—I’d prioritize engineering-oriented Chicago shops over traditional branding/web agencies. Based on their current public capabilities, my shortlist would be:

1. Reach Creative — best overall fit

Reach Creative
Web
Address: 321 S Jefferson St #3, Chicago, IL 60661, United States
Phone: +1 312-859-8747

Reach is probably my first call for the combination you described. They’re Chicago-based and publicly list Next.js, React, Node.js, TypeScript, GraphQL, Vercel and AWS, while also having real headless CMS experience through Prismic. prismic.io

Reach Creative

Why I'd shortlist them: good balance of product/design thinking and a modern developer stack. That makes them attractive if your MVP needs a polished frontend but you also want a codebase your eventual internal engineering team can inherit.

Best for: Next.js + headless CMS + custom integrations + strong UX.

2. Clique Studios — best if design/product experience matters

Clique Studios
Web
Address: 20 N Wacker Dr, Ste 1075, Chicago, IL 60606
Phone: +13123799329

Clique is a larger Chicago digital-product shop. They explicitly work with custom CMS solutions and modern frameworks, and their headless WordPress offering uses React/Next.js/Vue on the frontend. cliquestudios.com

Clique Studios

I'd consider them if your startup needs brand + UX + engineering together rather than hiring a separate product designer and development team.

Caveat: they may be more agency than you need for a very lean MVP. I'd ask for a small senior team rather than a large agency engagement.

3. Plego Technologies — best for an MVP that may become a real application

Plego Technologies
Web
Address: 8 W Monroe St APT 424, Chicago, IL 60603, United States
Phone: +1 630-541-7929

Plego is interesting because it explicitly markets startup MVP development and also builds web applications, not merely websites. Their CMS practice includes Strapi, alongside WordPress, Drupal and Magento. plego.com

Plego Technologies

Best for: MVP → SaaS/product evolution, custom APIs, application logic, integrations, and a headless CMS.

I'd put them ahead of a purely design-oriented agency if you expect the "website" to turn into a substantial application.

4. One North, A TEKsystems Company — technically strong, but probably too enterprise-oriented

One North, A TEKsystems Company
Web
Address: 227 W Monroe St #3500, Chicago, IL 60606, United States
Phone: +1 312-469-1740

One North has genuine headless CMS, web/mobile application, content modeling, CMS migration and platform architecture capabilities. cliquestudios.complego.comwww.onenorth.com

One North

The catch is their client base and organizational model: they work with major enterprises and have 165+ creative technologists. www.onenorth.com

I'd contact them only if: your startup has substantial funding, complicated integrations, enterprise customers, or unusually demanding security/governance requirements.

For a $30–100k MVP, I'd generally look elsewhere.

5. Adage Technologies — good for complex CMS architecture

Adage Technologies
Web
Address: 10 S Riverside Plaza Ste 1500, Chicago, IL 60606, United States
Phone: +1 312-258-1200

Adage is another technically serious option. They explicitly support headless/composable architectures, reusable content models and multi-channel publishing, with strong .NET/Umbraco/Optimizely expertise. adagetech.com

Adage Technologies

I'd favor them if your MVP has complex business rules, integrations, data, or enterprise CMS requirements. For a lightweight startup marketing site, they're probably overkill.

My ranking for your specific use case

The architecture I'd ask them to propose

For a developer-friendly startup MVP, I'd specifically ask each agency to price something along these lines:

Next.js + TypeScript → headless CMS → API/integration layer → Postgres where application data is needed → Vercel/AWS

For the CMS, I'd have them evaluate Sanity, Payload, and Strapi rather than automatically reaching for WordPress or Contentful. For an engineering-led startup, Sanity is particularly attractive for structured content and developer experience; Payload is compelling when you want the CMS to live closer to your TypeScript application/backend. www.evergreensite.com

The key is not letting the agency turn the MVP into an enterprise architecture project. I'd want the initial codebase to have:

• a clean Next.js/TypeScript foundation
• CMS schemas separated from UI components
• reusable content blocks rather than page-specific spaghetti
• typed API boundaries
• authentication/business logic outside the CMS
• automated deployments
• preview/draft content workflow
• tests around critical application logic
• GitHub repo and cloud accounts owned by you
• straightforward handoff documentation

If I were sending RFPs, I'd start with Reach, Plego and Clique, and give all three exactly the same MVP specification. That comparison would tell you much more than agency portfolios do.

For a startup, I’d optimize for engineering quality and architectural restraint, not just “web design.” In particular, I’d look for a team that can build a thin MVP on Next.js + a headless CMS + typed APIs, while leaving you with a codebase your own engineers can take over.

My Chicago shortlist:

1. Eight Bit Studios — best overall for a product-oriented MVP
   • Strong fit if the “website” is really the first version of a product.
   • They explicitly work on product strategy, MVP scoping, UX, and production web/mobile applications.
   • I’d shortlist them if you expect the marketing site to evolve into an actual application.

2. LaunchPad Lab — best for a technical product partner
   • More software/product consultancy than traditional web agency.
   • Good candidate when you want architecture, backend/API work, integrations, and iterative development rather than just a polished marketing site.

3. Vault Innovation — good startup/MVP orientation
   • Their positioning is specifically around helping founders and small teams turn ideas into working software, including MVPs. xcelacore.com
   • I'd investigate them if speed and pragmatism matter more than a big-agency process.

4. One North, A TEKsystems Company — strongest if the CMS side is complex
   • They explicitly offer CMS builds/migrations and headless approaches alongside application engineering.
   • Probably more agency/enterprise-oriented than what an early startup needs, but worth considering if you're expecting complicated content operations or integrations.

5. Doejo — good if design + startup speed are equally important
   • Chicago-based digital product/design/development shop with a startup-friendly reputation and custom CMS/product work. xcelacore.com
   • I'd put them ahead of a conventional branding agency if you need the MVP actually engineered.

One caveat: the best technical fit may not actually be Chicago-local

For the specific combination of headless CMS + Next.js + developer-friendly architecture, I would also interview Lucky Media even though it's not a Chicago-local shop. They specialize in Next.js and headless CMS rather than treating headless as an occasional project, and work with Sanity, Contentful and Storyblok. www.luckymedia.dev

Another technically interesting option is Otterdev, which builds Next.js/Astro sites with Sanity, Contentful and Strapi and also does CMS architecture/rescue work. otterdev.io

What I'd ask these agencies

For a startup MVP, I'd give each agency essentially the same architecture brief:

Next.js + TypeScript + headless CMS + Vercel, with a clean API/domain boundary and no proprietary agency framework.

Then ask:

• Which CMS would you choose and why: Sanity, Payload, Contentful, or something else?
• Can we own the GitHub repo and cloud/CMS accounts from day one?
• Is the CMS schema defined in code and version-controlled?
• Can our engineers replace you without rewriting the application?
• How do you handle preview/draft content, webhooks, ISR/cache invalidation, redirects and SEO?
• Where do you draw the boundary between CMS content and application data?
• What's your approach to authentication, database, background jobs and third-party integrations?
• Can you show us a real project where the initial MVP evolved into a larger application?
• What's explicitly out of scope for the MVP?

For a developer-led startup, I'd lean toward Sanity + Next.js or Payload + Next.js rather than choosing a CMS primarily for its visual page builder. Sanity has particularly strong Next.js integration, while Payload is attractive when you want TypeScript-defined schemas and more control over the application/CMS stack. xcelacore.comotterdev.iowww.sanity.io

My first three calls would be Eight Bit Studios, LaunchPad Lab, and Vault Innovation, then I'd benchmark their architecture proposal against a specialist like Lucky Media. That should tell you pretty quickly whether you're getting a genuine product-engineering partner or a traditional web agency with “headless” added to the services page.

For a startup looking for a headless CMS + developer-friendly MVP architecture, I’d bias toward agencies that think like product engineers rather than traditional “website shops.” The stack I’d expect them to be comfortable with is something like Next.js/React + TypeScript + a headless CMS (Sanity, Contentful, Storyblok, Strapi, Payload, etc.) + API-first backend + modern CI/CD.

A shortlist of Chicago-area teams I’d consider:

A few I’d put into “evaluate carefully depending on scope”:

• Adage Technologies — stronger for larger organizations, CMS/DXP implementations, and complex digital ecosystems than a scrappy MVP.
• Caxy — worth looking at for custom software/product engineering needs. www.builtinchicago.org
• DIESELHAUS — combines web/app development with CMS work, including headless approaches.

For a startup MVP specifically, I’d ask each agency these questions before signing:

1. What would your default architecture be for a 12-month MVP?

Good answer: “We’ll choose based on product needs.” Bad answer: “We always use WordPress/Webflow/whatever.”

2. Who owns the repo, cloud accounts, CMS account, and deployment pipeline?

You want everything in your organization’s accounts.

3. Can you show a project using:
   • Next.js or another modern frontend
   • headless CMS
   • API integrations
   • automated deployments
   • component-driven design system

4. How do you avoid MVP overengineering?

A good partner knows when not to build microservices, custom CMS platforms, or elaborate infrastructure.

My rough ranking for a technical founder:

1. TXI — if you’re building a venture-scale product
2. LaunchPad Lab — if the MVP is application-heavy
3. Nous Frame — if you want a lean, modern headless stack
4. Plego — if you need broader engineering capacity
5. Dom & Tom — if design/product strategy is a major requirement

I’d probably avoid hiring a generic “Chicago web design agency” for this type of project unless they can show actual headless CMS and application architecture work. clutch.co

Yes. For a startup that specifically wants headless CMS + developer-friendly MVP architecture, I’d avoid the generic “Chicago web design agency” category and shortlist firms that can actually own the architecture.

My Chicago shortlist

If it were my startup

I'd talk to Caxy, Tridence, and Musketeers first, but for different reasons:

1. Tridence — best overall match
If you're imagining something like:

Next.js → headless CMS → API/backend → Postgres → Vercel/AWS

with the possibility of adding authentication, payments, CRM integrations, etc., their published stack is unusually close to what you're asking for. tridence.com

2. Caxy — best if the MVP is actually a product
I'd pick them when the architecture matters more than minimizing the initial agency bill. Their Chicago engineering presence, senior-team model and experience with production platforms make them the safer choice for something you'll expect to operate for years. The downside is cost: they publish roughly $150K–$500K for custom projects and $15K technology assessments. www.caxy.com

3. Musketeers — best for speed/burn-conscious MVP development
Their stated approach is explicitly startup-oriented, with production architecture, Next.js, Supabase, Stripe, Vercel/AWS and a 6–10 week MVP target. I'd scrutinize their actual headless-CMS experience, though—their public material is much stronger on application MVPs than CMS architecture. musketeerstech.com

One important distinction

For a startup, I wouldn't automatically choose headless.

If the deliverable is primarily a marketing/content site, I'd want something like:

Next.js + Sanity/Contentful/Storyblok + Vercel

and keep the architecture deliberately boring.

If you're building a real SaaS MVP, I'd separate the concerns:

Next.js/React frontend
→ headless CMS only for editorial/content data
→ API/application layer
→ Postgres/Supabase
→ Stripe/Auth/etc.

That prevents the CMS from quietly becoming your application's database and gives a future engineering team a much cleaner handoff.

My ranking for your exact description: Tridence → Caxy → Musketeers → Parallel → Legible.

If you tell me your approximate MVP budget ($25k / $50k / $100k+) and whether it's a marketing site, SaaS app, marketplace, or content-heavy product, I can narrow this to 2–3 agencies and compare likely stack, cost, and agency fit.

For a startup, I’d bias toward agencies that think like product engineers, not just brochure-site designers. A good fit for a headless CMS + MVP stack usually means they can help with:

• Architecture choices (Next.js/React, APIs, database, auth, hosting)
• Headless CMS implementation (Sanity, Contentful, Strapi, Storyblok, custom CMS)
• Developer handoff (Git repos, CI/CD, documentation, clean code ownership)
• MVP iteration (shipping fast without creating throwaway code)

Here are Chicago-area agencies I’d shortlist:

A few other Chicago studios worth evaluating:

• DIESELHAUS — combines software development with CMS/web work and may fit startups needing more custom engineering.
• Adage Technologies — stronger for organizations needing CMS/DXP implementation and more complex digital platforms.

My shortlist by startup stage

Pre-seed / validating an idea

1. Vault Innovation
2. Adeocode
3. Nous Frame

Seed-funded startup needing a polished MVP + scalable foundation

1. Dom & Tom
2. Nous Frame
3. Plego

Marketing site + content platform (headless CMS first)

1. Nous Frame
2. cre8
3. One North

Questions I’d ask before hiring

1. “Will the code live in our GitHub organization?”
2. “Which headless CMS would you choose for us and why?”
3. “Can we replace your team later without rewriting everything?”
4. “What does your MVP architecture look like at 10x users?”
5. “Do you separate design system components from page templates?”
6. “Who is actually writing the code day-to-day?”

For a typical startup wanting Next.js + headless CMS + clean MVP architecture, I’d start conversations with Nous Frame, Dom & Tom, Vault Innovation, and Adeocode. They appear closest to the product-engineering mindset rather than a traditional marketing-agency workflow.

Yes. For a startup that wants a headless CMS without turning the MVP into an over-engineered enterprise project, I’d prioritize agencies that have both product-engineering chops and modern CMS experience.

My Chicago shortlist

1. LaunchPad Lab — best overall fit
   • Strongest match if the project is more than a marketing site and has a real product/MVP component.
   • They explicitly work on MVPs, technical architecture, React/Node/Postgres, and iterative product development; they say most web apps launch in 6–12 weeks. launchpadlab.com
   • Importantly for your use case, they also have dedicated Contentful development/integration capability. launchpadlab.com
   • I'd choose them if: you want one team responsible for product discovery → architecture → frontend/backend → CMS → launch.

2. TXI — best for architecture/product strategy
   • I'd consider them if the MVP has meaningful technical uncertainty or you expect it to become a substantial SaaS/product.
   • They're a Chicago product-engineering firm working with founders and explicitly emphasize discovery, architecture, iterative engineering and evolutionary product development. txidigital.com
   • They're probably more product consultancy than "web agency," so I'd put them ahead of conventional agencies when the architecture is the hard part.
   • Caveat: I found stronger evidence for their product/engineering capabilities than for deep specialization in a particular headless CMS.

3. One North, A TEKsystems Company — best headless-CMS-specific option
   • They explicitly offer headless CMS implementation, web/mobile applications and content migration. www.onenorth.com
   • Their engineering hiring material specifically mentions React, Next.js, Contentful, Sanity and Contentstack, including content modeling. www.onenorth.com
   • I'd choose them if: the website/content platform is a major part of the product and you want established headless expertise.
   • Caveat: they skew more toward larger/enterprise engagements than a scrappy founder-led MVP.

4. 7fridays — interesting smaller-agency option
   • Their Chicago listing shows modern JS capabilities including React/Next/Nest alongside Sanity and Strapi, while still doing traditional web work.
   • That combination makes them worth talking to if you want a smaller shop and a relatively pragmatic stack.
   • I'd choose them if: budget and hands-on developer access matter more than a big strategic consulting process.

5. Clique Studios — good for content-heavy products
   • Chicago-based and combines UX/design with engineering, CMS implementation, APIs and integrations.
   • Their current capabilities include Contentful, alongside WordPress/Drupal and custom engineering.
   • I'd choose them if: the MVP has a substantial brand/content/experience component rather than being primarily an application.

How I'd rank them for your exact brief

Stack I'd ask them to propose

For a new startup, I'd specifically ask each agency to price/architect something along the lines of:

Next.js + TypeScript + headless CMS (Sanity/Contentful/Payload) + Postgres + Vercel/AWS, with the CMS isolated from the application domain.

I'd lean Sanity + Next.js for a content-heavy startup because the schema is code-defined and the integration is particularly developer-oriented. Sanity itself describes its Next.js integration around React, typed/structured content, SSR/SSG/ISR and live preview. www.sanity.io

The key is not merely asking "Can you build a headless CMS site?" Ask them:

"Can you design an MVP architecture where the CMS, frontend and product backend are independently replaceable, with minimal technical debt and a clean path from MVP to an in-house engineering team?"

That question will separate the agencies I'd seriously interview from agencies that simply know how to connect a CMS API to a Next.js template.

If I were taking three calls, I'd start with LaunchPad Lab, TXI, and One North. For a tighter startup budget, I'd swap One North for 7fridays.

Yes. For a startup, I’d prioritize engineering/product agencies over traditional “web design” shops—especially if you want the CMS and frontend to remain maintainable after the MVP.

My Chicago shortlist:

1. TXI — best for product architecture
   • Strongest choice if the project is really a product/MVP, not just a marketing site.
   • They combine product strategy, UX, engineering, and evolutionary architecture. Their Chicago team works on custom digital products rather than template-driven websites.
   • I’d consider them if you need help deciding what the MVP architecture should be before committing to a stack.
   • Caveat: they're not as specifically headless-CMS-focused as some of the others.

2. LaunchPad Lab — best for a startup building an actual web app
   • Very relevant if your “website” is actually becoming a SaaS/product experience.
   • Their focus is custom web/mobile applications and product development rather than primarily marketing websites.
   • I'd shortlist them when the CMS is one component of a broader application architecture.

3. DIESELHAUS — good smaller-team option
   • They do both web applications and CMS work, including headless approaches and custom CMS development.
   • More attractive than a conventional agency if you want one team to handle frontend + backend + CMS + deployment.

4. Thirdwave — good for maintainable CMS-heavy sites
   • Chicago-based development shop with a focus on reliable, maintainable web platforms.
   • I'd look at them for a content-heavy startup where information architecture, integrations and CMS customization matter.

5. Adage Technologies — technically capable, but probably larger than you need
   • Stronger fit when the startup has complex integrations, commerce, or enterprise-style CMS requirements.
   • They explicitly handle CMS/DXP selection and implementation alongside custom software and API integrations.
   • I'd put them lower on the list for a lean MVP because they may be more agency than you need initially.

One important caveat

The best technical match I found isn't actually Chicago-local: Lucky Media has an unusually strong combination of Next.js + headless CMS + MVP development. They explicitly offer Sanity, Contentful and Storyblok with Next.js, and separately advertise full-stack MVP development and modular architectures designed to avoid turning the MVP into technical debt. www.luckymedia.dev

For your particular requirements, I'd seriously include them in the RFP even if Chicago-local isn't mandatory.

What I'd ask for

For a startup, I'd specifically ask each agency to propose something along these lines:

Next.js + TypeScript + headless CMS + managed Postgres/API layer + Vercel/AWS, with a clean separation between:

• content/editorial data
• application/business data
• frontend
• authentication
• third-party integrations

For the CMS, Sanity is probably my first thing to evaluate for a developer-friendly MVP. Its structured content model, API approach and tight Next.js integration make it particularly suitable for a developer-led team. www.sanity.io If self-hosting/control is more important, I'd also evaluate Payload; if you're anticipating a larger marketing organization, Contentful is worth considering.

My top three for your use case: TXI if architecture/product discovery is the priority, LaunchPad Lab if you're building a real application, and DIESELHAUS if you want a smaller Chicago team that can handle the whole stack.

If you tell me your rough MVP budget ($25k / $50k / $100k+) and whether this is primarily a marketing site or an actual SaaS/web app, I can narrow this to 3 agencies and compare them on CMS expertise, Next.js/React depth, MVP experience, likely cost, and agency size.

Yes. For a startup that specifically wants headless CMS + a developer-friendly MVP architecture, I’d bias toward engineering/product studios rather than traditional Chicago branding agencies.

My Chicago shortlist

If it were my project

I'd interview Nous Frame, Dom & Tom, and Reach Creative first.

1. Nous Frame — best for a lean build.
Their model is unusually aligned with what you're describing: small senior team, React, headless CMS, APIs, and no account-manager layer. They explicitly use Sanity and Storyblok and say clients work directly with the people doing the design/build. nousframe.com

2. Dom & Tom — best if the MVP has real application complexity.
If you're building authentication, subscriptions, dashboards, workflows, integrations, marketplace functionality, etc., I'd move them to #1. Their current positioning is explicitly around founders, MVPs, product strategy, architecture and full-stack engineering. domandtom.com

3. Reach Creative — best middle ground.
They look attractive if the project is primarily a sophisticated web experience but still needs genuine engineering underneath. Their published stack—Next.js/React/Node/TypeScript/GraphQL/Vercel and Prismic—is very compatible with a headless architecture.

One architectural point I'd push them on

For a startup MVP, I wouldn't let the agency sell you a complicated "composable architecture" just because headless is fashionable.

A very sensible starting point is something like:

Next.js + TypeScript + Sanity/Storyblok + managed Postgres/backend + Vercel

Then keep the CMS responsible for structured editorial content, while application data, authentication, billing, business logic, etc. live in the application/backend layer.

Sanity is particularly attractive for a developer-led team because its content schemas can be defined in code and its Studio is customizable; Strapi/Payload can make more sense when you want greater ownership/self-hosting. www.simplerdevelopment.com

I'd also ask every agency these five questions before choosing:

1. Can we own the GitHub repo, cloud accounts, CMS account and deployment accounts from day one?
2. What would you put in the CMS versus the application's database?
3. Can you show me a recent Next.js + headless CMS codebase rather than just a marketing-site portfolio?
4. How do you structure an MVP so we can replace the agency with an internal engineering team later?
5. What would you deliberately not build in v1?

That last question is especially revealing. For a startup, I'd generally prefer the agency that proposes the simplest architecture that can survive the first 12–18 months, rather than the most elaborate one.

If you tell me roughly what the MVP does, your budget ($25k/$50k/$100k+), and whether it's primarily a SaaS product or content/marketing site, I can narrow this to 3 agencies and compare their likely fit, technical approach, and engagement model.
