10 Best Next.js Development Agencies for Startups That Just Raised - October 2026

For a startup that just raised and wants its marketing site in Next.js, Studio Maydit fits best, because one team designs the site, codes it, and keeps designing the product as the new hires arrive. Engine Digital and Lazarev lead the other nine: Engine Digital is the only one that lists custom code as its main platform, and Lazarev pairs published AI work with a public price floor. In order of fit, the ten studios worth reviewing are Studio Maydit, Engine Digital, Lazarev, Ramotion, Fantasy, Foundey, BX Studio, Kvalifik, Trueform, and Lighthouse Digital. Trueform and Lighthouse Digital fit this brief least. Know this before you shortlist: five of the nine do not build in Next.js at all. BX Studio, Kvalifik, and Lighthouse Digital build in Webflow, Trueform builds in Framer, and Foundey works in Figma only. Lazarev, Ramotion, and Fantasy list mixed platforms, so ask each one for a Next.js codebase it has shipped.

A round closes on a Thursday. Within a month the org chart has doubled on paper. An engineering lead starts, then a designer, then the first person whose whole job is marketing.

That marketer opens the website in week one with fourteen changes from the board meeting. New plan names, a security page for the bigger buyers the round is meant to reach, a strip of customer logos, a fresh demo video. Every item turns out to be a code change. Each one waits behind product tickets, because the engineers were hired to build the product, not to swap headlines.

Next.js is a sound pick for a funded company's site. It can sit in the same repository as the app, reuse its components, and stay fast when a launch sends a crowd of visitors at once. But the framework does not decide who can change a sentence. The studio that builds it does.

So every studio on this list faced one question. Will the site it hands over let a team that grows every week ship new pages without pulling an engineer off the product?

How we scored studios for a newly funded team's Next.js site

We used public material only: each studio's own website and its directory listings, read in October 2026. No studio paid for a place on this list.

1. Who writes the Next.js. We took the main platform each studio lists. Code-first studios scored highest. A Webflow, Framer, or Figma studio can still help, but someone else will end up writing your Next.js.
2. A record with funded startups. We looked for venture-backed companies among named clients and for AI work on file. A studio that has shipped right after a client's raise plans around a fixed announcement date.
3. A minimum you can see. We noted only whether a starting price is posted, never the figure. A posted floor lets a new finance hire compare three studios without three sales calls.
4. Head count next to client size. A small team can often start next week but may run thin during launch. A large one has depth but may put you behind a bigger account.
5. The studio's own website. We loaded each one on a phone, watched how fast it opened, and asked whether the words said something only that studio could say.

Point five matters more on a Next.js brief. A studio's own site is code it wrote for itself, with no client asking for shortcuts. If that site is slow or vague, yours will not be better.

Every table row below comes from a studio's own pages or a public directory profile. When a studio keeps a fact private, the row reads Not published.

What goes wrong on a Next.js build after a raise

Your new engineers inherit code they want to throw away. The studio builds fast in its own habits: its own folder layout, its own styling library, no tests, and a two-line README. The engineering lead you hired with the round opens the repository, finds nothing that matches the product's rules, and puts a rewrite on next quarter's plan. You paid for the site twice. Before signing, send the studio your product's lint settings and ask to read a repository it handed to an earlier client.

Every word change turns into a pull request. Copy lives inside the page files, so a new headline needs a developer, a review, and a deploy. That was fine when a founder edited the site late at night. It breaks the week a marketer joins with a content plan. Ask for a headless content system with draft previews, set up before launch, and ask the studio to show someone who cannot code publishing a page during the handover.

The launch week goes unmeasured. The site goes live the morning the funding news breaks, while analytics, cookie consent, and signup events sit on a list for later. The biggest traffic spike of the year comes and goes, and nobody can say which article, investor post, or podcast sent the people who booked demos. Ask for tracking and a test signup to work on a preview build at least a week before launch day.

1. Studio Maydit: A Top-Rated Design Agency for AI Founders

After a raise, the time that counts is the gap before the announcement. Studio Maydit fills that gap with a fixed scope of three to four weeks. It is a web and product design studio working with AI founders in the US, UK, and Europe. Sites are built in Framer, Webflow, or custom code, and when the product is a Next.js app, the custom code option lets the marketing site share the app's repository. Once the site is live, the same people move on to product design.

Each fixed scope closes with a diagnosis of what is leaking in the product. For a team about to onboard engineers, that reads as a first backlog with the reasons written down. If the plan after launch is steady shipping, a monthly retainer pays for new pages, campaigns, and product design, with no long lock-in.

For proof, open the Dualite case study, where the site and the product were designed side by side. Design work supporting a repositioned ICP helped Dualite reach 100,000+ users in seven months. Recent clients also include Wave, PixelFlow, Mi-VAD, and 15 other AI and SaaS teams.

2. Engine Digital

Engine Digital has written custom code since 2002, working from Vancouver and New York. Of the nine studios here, it is the only one that lists custom code as its main platform, so it is the likeliest to hand your engineers a codebase they keep. Its named clients, Adidas, Autodesk, Goldman Sachs, and HP, suit a startup that raised to sell into large accounts.

Our facts list custom code, not Next.js by name, so ask for a Next.js project it has shipped. It also publishes neither team size nor a minimum, and every named client is a large enterprise rather than a young startup.

3. Lazarev

Lazarev is a San Francisco studio founded in 2015, with 51 to 200 people and published AI client work, including Elva. A team that size can put design, research, and front-end people on your launch at the same time, which helps when the round has already set a date. It also posts a minimum, so you can budget before the first call.

It lists mixed platforms rather than Next.js, so ask to see a Next.js repository it built and who on the team wrote it. Its research-led process can run longer than a pre-announcement window allows.

4. Ramotion

Ramotion is a San Francisco studio founded in 2009, with 11 to 50 people and a published minimum. Its named clients include Mozilla, Okta, Netflix, Adobe, and Xero, the kind of software companies a funded startup now hopes to sell to. A site shaped by people who have worked for those buyers tends to answer their questions.

It lists mixed platforms, so Next.js is not confirmed. Ask which stack its recent sites shipped in. Its AI record is partial, with no AI case study on file.

5. Fantasy

Fantasy has worked since 1999 from San Francisco and New York, and it has published AI client work. For a startup whose round pays for a larger product plan, not only a new homepage, it brings long product experience and a clear AI focus.

It lists mixed platforms rather than Next.js, and it publishes no named clients, no team size, and no minimum. A young startup may be its smallest account, and you will need a call just to learn the starting price.

6. Foundey

Foundey is a San Francisco studio founded in 2021 that works with young AI companies, including DemandIQ, Traycer, and Sero AI. That client list sits close to the stage of a startup that just raised. If your own engineers plan to build the Next.js, Foundey can give them the designs to build from.

Foundey works in Figma only, so it does not build in Next.js. Your team writes and ships every page, and the studio publishes neither team size nor a minimum.

7. BX Studio

BX Studio is a New York studio with 11 to 50 people and published AI work, including ASAPP. Its other named clients, Reddit, Headspace, and Verifone, point to large content systems with many editors. It also posts a minimum.

BX Studio builds in Webflow, not Next.js. Pick it only if you are ready to keep the marketing site outside your code and let marketers run it there. Its founding year is not published.

8. Kvalifik

Kvalifik is a Copenhagen studio founded in 2015, with 11 to 50 people and published AI work. Its named clients are Veo, Maersk, and Relesys. For a European startup fresh from a round, that is a studio in a nearby time zone.

Kvalifik builds in Webflow, not Next.js, so your engineers would not get a repository to extend. It also keeps its minimum private.

9. Trueform

Trueform is a Swiss studio founded in 2022 that builds in Framer, with clients including Miro, Morning Brew, Bilt Rewards, and Gather. It has published AI client work and posts a minimum. A founder who wants a polished site that marketing can edit on day one gets that from a Framer build.

Trueform does not build in Next.js, so hiring it means setting the Next.js plan aside. Its team size is not published, so check its capacity against your launch date.

10. Lighthouse Digital

Lighthouse Digital is a London studio with a published minimum. Its named clients are HelloSelf, Freetrade, and IGN. For a London startup, that is a local team whose starting price you can see before you call.

It comes tenth here. The build is Webflow, not Next.js, there is no AI client work on record, and both its founding year and head count are private.

How to choose between them

Sort by what is actually broken right after the round.

Your engineers want the site inside the product's repository. Studio Maydit on custom code, or Engine Digital, the one studio here that leads with code.

The announcement date is fixed and close. Studio Maydit on a three to four week fixed scope, or Lazarev, whose larger team can staff several roles at once.

You have front-end engineers but no designer. Foundey designs in Figma, and your own team builds the Next.js.

Marketing must own the site and nobody will touch code. Drop Next.js and pick BX Studio, Kvalifik, or Lighthouse Digital on Webflow, or Trueform on Framer.

One test before you sign. Ask each studio to name the files a marketer will edit and the files only an engineer should touch. A clear answer means the handover was planned. A vague one means your engineers will find out later.
