8 Best Next.js Agencies for B2B Websites (2026)

These are eight agencies we would put in front of a B2B company that has decided its marketing site should run on Next.js. Each one has live B2B work you can open today, where we confirmed Next.js in the page source, and an official listing in Vercel's partner directory. They answer different needs, from design-led launch sites to 300,000-page migrations, so use the fit notes, not the order.

Our own studio is listed first, as on our Framer shortlist, with a disclosure: it doesn't meet the live Next.js criterion, so it isn't one of the eight.

How we chose

Every agency on this list meets three criteria:

• Live B2B work on Next.js that you can open. For each agency we took clients named in its own case studies or on its official partner listing, loaded the live site and checked the HTML for Next.js build output: assets under /_next/static/ plus a __NEXT_DATA__ or self.__next_f script. A case study alone wasn't enough. Several showcase projects we looked at have since moved to other platforms.
• Official proof of standing. Every agency is in Vercel's solution partner directory, which shows a Platinum, Gold or Silver tier. We also checked Sanity's agency partners and Storyblok's partner finder, and link those listings where they exist.
• A clear specialty, so each entry answers a different need.

Our bias, stated once: we build on Framer, Webflow, WordPress, Next.js and Astro, we're an Official Framer Expert, and our own site runs on Astro and Sanity. No agency asked or paid to be here.

How to choose a Next.js agency

Six questions separate a Next.js website partner from a React team that happens to build websites.

1. Which pages are static, and how does a published edit go live? Pages are Server Components by default, and routes without dynamic APIs are prerendered at build. On a marketing site most pages should be static. Ask how a CMS edit reaches the live page: a rebuild, a timer, or on-demand revalidation from the CMS. A good answer names the rule per page type.
2. Which CMS, how do editors preview, and what can they build alone? Draft Mode shows editors unpublished content on the real page while visitors keep the cached version. It isn't available on a static export. Ask to watch a marketer build a page from existing blocks on a live client project; new layouts still need a developer (a CMS your team can run).
3. Where will it be hosted, and on whose plan? Vercel's Hobby plan is for non-commercial personal use only, so a company site needs Pro ($20 a month with one deploying seat) or Enterprise. Next.js also runs on a Node.js server or Docker with all features; several self-hosted instances need a shared cache for revalidation.
4. Who owns the repository and the accounts? Next.js is MIT-licensed, so the code can be fully yours, but only if the GitHub organisation, hosting team, CMS project and domain sit in your company's name from day one (who owns your website after launch).
5. What is the performance budget? Google's Core Web Vitals targets are LCP within 2.5 seconds, INP of 200 milliseconds or less and CLS of 0.1 or less, at the 75th percentile of page loads. Ask for field data on two live client sites, not a Lighthouse screenshot, and which components ship JavaScript and why. On our own rebuild, font metric overrides and reserved image space took layout shift from 0.19 to 0 before launch.
6. How will they handle the migration and redirects? Next.js sets permanent redirects in its config with a 308 status; a static export can't, so redirects then live at the host. Ask for a URL inventory from the old CMS, not only a crawl; we shipped about 80 redirect rules the day our own site switched (our checklist).

The agencies

AGR Studio (our own studio)

Read this with the disclosure in mind: we have no public Next.js case studies, so AGR Studio doesn't meet our first criterion. Our public client work is on Framer and React: Finite uses custom React and TypeScript components inside Framer, and we rebuilt RealAgentLink's landing page in React with Tailwind. Our own site was started in Next.js and launched on Astro and Sanity (why).

We're here for design-led B2B sites that sit next to a Next.js product, and for teams still deciding whether they need Next.js at all (Astro vs Next.js, Webflow vs Next.js). Our site ships llms.txt, a Markdown version of every page and an AI visibility check.

Standing: Official Framer Expert, 4.95 out of 5 across 40 reviews on Contra, and clients including Marcura and Janus Henderson.

Best fit: B2B brands that want brand and site from a small senior team. Not right for: a team that needs a proven Next.js engineering partner today.

Webstacks

A San Diego agency that works with B2B tech companies and treats the website as a product: design, build, migrations and ongoing management. Its Vercel listing describes Braze's marketing site as built with Next.js, Sanity and Vercel, and its 9fin case study covers a fintech rebuild on Sanity, Next.js and Vercel. It also works in Contentful, Builder.io and Storyblok.

Standing: Platinum on Vercel, a Sanity agency partner and a Storyblok Platinum Partner. Budget bands on its Vercel and Sanity listings start at $50,000.

Checked: braze.com and 9fin.com serve Next.js pages.

Best fit: SaaS and fintech marketing teams with little in-house web engineering. Not right for: budgets under $50,000.

Monogram

An Atlanta studio that now calls itself an applied AI studio and says it was Vercel's first agency partner. Its CrewAI case study covers a marketing site and developer portal on Next.js and Contentful with OpenAPI and Model Context Protocol surfaces. The Kasada site runs on Next.js and Sanity, with llms.txt and a Markdown sitemap so AI assistants can read it.

Standing: Platinum on Vercel, with Next.js, Vercel and AI Cloud certifications on the listing, and a Sanity agency partner.

Checked: crewai.com and kasada.io serve Next.js pages.

Best fit: AI and developer-tool companies whose site serves engineers and AI agents as well as buyers. Not right for: a brochure site with no product integration.

Together

A London-based, fully remote team of 30+ that works with B2B tech companies on positioning, brand and website as one project, per its Vercel listing. Its Rogo case study covers taking a stealth AI financial-research company to market, including website design, content and build. Coder and zeroheight are similar B2B projects.

Standing: Silver on Vercel.

Checked: rogo.ai (now rogo.com), coder.com and zeroheight.com serve Next.js pages. Not every Together site is Next.js: unit.co, another client, runs on Webflow, so ask which platform they propose and why.

Best fit: B2B tech companies at a launch, rebrand or repositioning moment. Not right for: teams with settled brand and messaging that only need engineering capacity.

basement.studio

A design studio with teams in Mar del Plata, Buenos Aires and Los Angeles, covering branding, immersive experiences, web and marketing; on its Vercel listing it says it specialises in Next.js. Its showcase includes Harvey, where it built the brand and website from seed stage, and Scale AI, which it has supported on website and marketing since 2021.

Standing: Silver on Vercel.

Checked: harvey.ai, scale.com and basement.studio itself serve Next.js pages.

Best fit: venture-backed AI companies that want a distinctive, motion-heavy brand site. Not right for: a large content migration with little design scope.

Bejamas

A remote-first consultancy based in Wrocław, Poland, per its Storyblok listing, positioned as the long-term web team for multi-brand, multi-market sites. Its Rippling case study covers moving Rippling's marketing platform off a legacy WordPress setup to Contentful and Next.js between 2024 and 2026. Veezu is another WordPress to Next.js move, and Newfront a decoupled Next.js site for an insurance company.

Standing: Silver on Vercel, a Sanity agency partner and a Storyblok Platinum Partner. It starts with a fixed-price audit or discovery, or a quarterly retainer.

Checked: rippling.com, newfront.com and veezu.co.uk serve Next.js pages.

Best fit: established B2B companies leaving WordPress or Sitecore for a headless stack. Not right for: a single campaign landing page.

Tinloof

A fully remote agency of 25+ people, registered in Berlin and working since 2020, with 100+ Sanity projects by its own count (tinloof.com). Its Ramp case study describes working with Ramp's engineering team to move ramp.com, a marketing site with 300,000+ pages, from Webflow to Next.js and Sanity with zero downtime, under a brief that ruled out SEO regressions. Its Vercel listing also names Watershed, where it set up content management for the marketing team.

Standing: Silver on Vercel and a Sanity agency partner.

Checked: ramp.com and watershed.com serve Next.js pages.

Best fit: fintech and SaaS teams moving a large Webflow site to Next.js and Sanity, or engineering teams that want Sanity specialists alongside them. Not right for: teams set on a CMS other than Sanity.

Blazity

A Warsaw engineering team focused on Next.js performance, rendering and caching, and on moving legacy CMS setups to Next.js. It also builds enterprise AI agents. Its Speechmatics case study covers a speech-AI marketing site on Next.js and Contentful with improved Core Web Vitals. Planday is a workforce-management SaaS site on Next.js and Hygraph that marketing now publishes to across European markets.

Standing: Gold on Vercel, with Next.js, Vercel and AI Cloud certifications on the listing, and a Sanity agency partner.

Checked: speechmatics.com and planday.com serve Next.js pages.

Best fit: sites where Core Web Vitals and search tie to pipeline, or a Next.js site that has become slow. Not right for: a rebrand, since brand identity isn't among its listed services.

FocusReactive

A headless CMS agency founded in 2019, with offices in Amsterdam, London and Warsaw (about); its team also runs JavaScript conferences such as React Summit. It builds block libraries so marketers assemble pages themselves. The Xweather case study moves a weather-data company from a single-page app to Next.js and Storyblok with 77 section components, and EmailOctopus moves 400+ pages from WordPress to Payload CMS and Next.js.

Standing: Silver on Vercel, a Sanity agency partner and a Storyblok Community Partner.

Checked: xweather.com and emailoctopus.com serve Next.js pages.

Best fit: marketing teams that want to build pages from blocks without a developer. Not right for: brand identity work, which isn't among its listed services.

Who we left out

• Global networks and enterprise consultancies. Several Platinum partners do excellent work, mostly for consumer brands, commerce or large experience platforms.
• Commerce-first and app-first studios whose public work is storefronts or product software.
• Agencies we couldn't verify: no B2B client site we could confirm runs Next.js today, or no official partner listing.
• Solo freelancers and template shops.
