10 Best Next.js Development Agencies for Pre-Seed AI Startups - October 2026

Summarize with AI

For a pre-seed AI startup that wants its website built in Next.js, Studio Maydit fits best, because it builds in custom code, works to a fixed scope of three to four weeks, and stays on to design the product once users arrive. Feels Like and Phantom lead the other nine, as the only two that list custom code as their main platform, and both have published AI work. Ranked by fit, the ten studios worth reviewing are Studio Maydit, Feels Like, Phantom, Lazarev, Fantasy, Digidop, Push Refresh, 8020, Edgar Allan, and Refokus. Edgar Allan and Refokus fit least: both are premium Webflow studios serving large brands. To be plain about the stack, none of the nine names Next.js as its framework. Digidop, 8020, Edgar Allan, and Refokus build in Webflow and Push Refresh builds in Framer, so those five would not write your Next.js at all. Lazarev and Fantasy work across mixed tools.

Picture two founders building an AI tool that turns sales call recordings into CRM notes. They have twelve design partners, half an angel round, and a Next.js app started from a template four months ago. There is no website as such. The root page sends logged-out visitors to a sign-in box, and the browser tab still reads Create Next App.

An angel opens the link from their deck on her phone between meetings. She sees a Google sign-in button and nothing else, and she does not sign in. In the founders' analytics, her visit looks like any other.

For this team, Next.js is the right home for the website. The app already runs on it, the engineer founder knows it, and a few public pages beside the product cost less than a second tool with its own login and bill. The job is small: three to six pages that say what the product does, show it working, and collect sign-ups. The hard part is doing it inside a young codebase that changes daily, without slowing the one engineer who also builds the product.

So we put one question to every studio. Could it add those pages to your app this month, cleanly, and leave the founders able to change them the week after?

Most AI products look the same. Yours doesn't have to. Client logos: Sathi, Dualite, Chariot, Pixelflow, Accocorp. Book an intro call with Studio Maydit.

How we checked each studio for a pre-seed Next.js build

We read each studio's own website and its public directory listings in October 2026. Nothing here was sponsored.

  1. Who writes the Next.js. We checked the main platform each studio lists. A custom code studio can work in your repository. A Webflow or Framer studio builds somewhere else.
  2. AI work with young products. We looked for named AI clients and published AI projects. A studio that has explained a young model-based product before learns yours faster.
  3. A minimum you can see. We noted whether a floor price is public, never the number itself. On angel money, a posted floor lets you skip a call you cannot afford.
  4. Their team next to yours. We compared headcount with the clients each studio names. A two-person company is a tiny account at a studio that serves Spotify or SAP, and tiny accounts wait their turn.
  5. The studio's own homepage. We opened each one on a phone with no context. Could we tell in a few seconds what the studio does?

We gave the fifth check the most weight. A studio's homepage is the one project where it chose the words, the stack, and the deadline itself. Whatever it settled for there is what it will settle for on yours.

Every fact in the tables traces to a studio's own site or a public directory profile. Where a studio keeps a number private, its table says Not published rather than a guess.

What goes wrong when a pre-seed AI startup hires for Next.js

Logged-out visitors still hit the sign-in screen. The studio designs a sharp homepage, but the app's middleware guards every route, so anyone without a session gets bounced to the login page. The founders never notice, because they are always signed in. Link previews in chat apps show the login page too. Ask the studio to list which routes are public, and to open each one in a private window on a phone before handoff.

The waitlist form saves nothing. Before seed, design partner sign-ups are the traction slide in the deck. The studio wires the form to a server action, using a key that exists on its own laptop and not in production. The button turns green, a thank-you message appears, and no row is saved. Three weeks of sign-ups vanish before anyone looks. Ask the studio to submit the form on the live site on launch day and show you the new entry.

The build eats your only engineer's week. A studio working inside your app needs access, environment variables, code review, and answers about how sign-in works. At pre-seed all of that comes from one person, who is also shipping the product. If every pull request waits on them, a four-week project takes eight. Ask how many hours a week of your engineer's time the studio expects, and whether a non-technical founder can approve pages from preview links instead.

The Studio Maydit website: design partner for taste obsessed AI companies

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

Before seed, a team needs a website that explains the product to an angel in under a minute, and a hard look at the product before early testers stall. Studio Maydit covers both. 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 for an app already on Next.js, custom code is the route that sits beside the product. After launch, the work carries on into product design.

A fixed scope takes three to four weeks, which fits the gap between the first angel check and the wider round. It ends with a diagnosis of what is leaking in the product, so you learn where testers drop off while there are only a few dozen of them. Once the money is in and the team ships every week, a monthly retainer covers new pages, campaigns, and product design, with no long lock-in.

The result to weigh is Dualite, an AI dev tool. Design work supporting a repositioned ICP helped it reach 100,000+ users in seven months. Read how the site and the product moved together in the Dualite case study. The client list also runs to Wave, PixelFlow, Mi-VAD, and 15 other AI and SaaS teams.

2. Feels Like

Feels Like is a Los Angeles studio founded in 2023, nearly as young as some of the companies it would serve. Custom code is its main platform, and it has published AI work, with Suno AI named next to Google, Nike, and LVMH. That pairing is rare in this pool, and the studio sits in its middle tier rather than the premium one.

It does not say which framework it codes in, so confirm Next.js first. Team size and pricing are not published, and a two-person startup may compete with big brands for attention.

3. Phantom

Phantom has studios in London and Auckland, was founded in 2013, and has 51 to 200 people. It builds in custom code and has published AI work for clients such as SAP, Zendesk, Diageo, and the Financial Times. If your pitch only lands when people see the model run, Phantom can build a working demo in the browser.

It is a premium studio at agency scale with pricing not published, so few pre-seed budgets stretch to it. It does not name Next.js, and its work leans toward campaigns.

4. Lazarev

Lazarev is a San Francisco studio founded in 2015, with 51 to 200 people and published AI work, including Elva. Its process starts with research, which helps when design partners keep asking what a screen means. It posts a minimum, so you can check the fit before a call.

Its platform is mixed, not Next.js, so your engineer may end up coding its designs. It is premium, and research can run longer than a raise allows.

5. Fantasy

Fantasy has worked since 1999 from San Francisco and New York, and it leads with AI strategy next to product and brand work. For founders still arguing about what the product is for, that can settle the story before any page is built.

It names no clients publicly, and its team size and pricing are not published. Its platform is mixed, not Next.js, and at enterprise scale a pre-seed company would likely be its smallest account.

6. Digidop

Digidop is a Paris studio founded in 2021, with a team of 1 to 10 and a posted minimum. Its named clients include StreamNative, a data streaming company, so it has explained a technical product before.

It builds in Webflow, not Next.js, so the site would live outside your app on a second tool. Its AI proof is partial, with no AI case study named.

8020 works from San Francisco and New York and was founded in 2014. Its named clients read like a list of venture-backed software startups, such as Vanta, Pilot.com, and Superlist.

It builds in Webflow, not Next.js, so your app and your site would sit on two stacks. Its AI proof is partial, and its team size and pricing are not published.

9. Edgar Allan

Edgar Allan is an Atlanta studio founded in 2014, with 51 to 200 people and clients including Porsche, Duracell, and NCR. It suits large Webflow builds run by a full marketing team.

That is the opposite of a pre-seed company with no marketer. It builds in Webflow, not Next.js, it is a premium studio, pricing is not published, and its AI proof is partial.

How to choose between them

Sort by what an angel sees today when she opens your link.

A sign-in box, or a starter page with a default title. You need public pages added inside your app. Studio Maydit, or Feels Like once it confirms it codes in Next.js.

A clear page, but the product only makes sense when it runs. Phantom, if the round can pay for a working demo in the browser.

Pages that exist, yet nobody can say what the product does. That is a story problem first. Lazarev for the product screens, or Fantasy for the strategy.

You have decided the site can live outside the app until seed. Digidop or Push Refresh at a posted minimum, or 8020 for its startup client list. Edgar Allan and Refokus are better kept for a later stage.

One test before you sign. Send the studio your live link and ask what a logged-out visitor sees on a phone in the first five seconds. If it answers without opening the link, keep looking.

Frequently given answers

Sid, founder of Studio Maydit

Looking for something else?

Book a call with the founder.

Mostly AI and SaaS teams who have outgrown their design: a site that no longer explains what they do, a product people sign up for but do not stick with, or a launch coming faster than their team can design for. They need senior design without building an in-house team.

Websites and products. For websites: positioning, copy, design, and a Framer, Webflow, or code build that turns visits into demos and signups. For products: research, flows, UI, and a design system, so users get value sooner and engineers have clear designs to build from.

A senior designer, assigned from day one, works on your project with Sid, our design lead, who you meet on the discovery call. You talk to both of them directly in Slack and on reviews, and the same people stay with your project from start to finish.

You work directly with the designers on your project, and you can see progress in Slack and Figma as it happens. At the end of every project, we also give you a written note on what is working well and what we would improve next.

Hiring can be the right call once design is a constant need. Until then, one person rarely covers brand, website, product, and build, and a senior hire can take months to find. We cover all of these from the start, and you can scale us up or down as your roadmap changes.

It depends on scope: a fixed price for a defined project, or a monthly retainer for ongoing work. Book an intro call and we will send a clear quote after hearing what you need.

Fixed scope suits work with a clear end point, such as a website, a launch page, or a defined set of screens. A retainer suits design that needs to keep pace with a roadmap that keeps changing.

A focused landing page or homepage usually takes two to three weeks. A full marketing site takes about four to six. Custom illustration, heavy motion, or a custom code build adds time, and we agree the timeline before we start.

Mostly through Slack with regular check-ins, and everything happens in Figma where you can comment directly. You always know what is in progress and what ships next.

Yes. A single landing page, an audit, or one core flow is a good way to see how we work before committing to more. Plenty of longer partnerships started that way.
