How We Built This 2026 Shortlist
We ignored the flashy portfolio mockups and only looked at live B2B SaaS sites you can click through today. For every agency on this list, we clarified exactly what they contributed, whether that was just the UI design, the Webflow migration, or the entire brand and copy overhaul. That way, you know exactly what each case study actually proves before you use it to judge their fit.
Full disclosure: GrowUp is our agency, so naturally we’re up first. We’ve linked our live projects directly in the text so you can compare our work with anyone else on this list.
Quick Comparison: Top B2B SaaS Web Design Agencies 2026
| Agency | Best For | Pricing | Key Differentiator |
|---|---|---|---|
| 1. GrowUp | B2B SaaS companies in complex categories where the website needs to rank in search and support pipeline generation. | From £8,500 per project | SEO + copy from day one. Strategy, messaging, copy, SEO, and AI-search visibility are considered from the start and carried through the design and build. |
| 2. Webstacks | Large B2B SaaS sites with multiple products, audiences, languages, or complex content structures. | Quote-based, not publicly available | Large-scale replatforming. Strong fit for companies moving from WordPress to composable or headless architecture without rebuilding the entire site in one go. |
| 3. BRIX Agency | SaaS startups looking for a custom Webflow site without a long development process. | From $10,000 per project | Webflow-first execution. Modular sections, animations, integrations, and hands-on Webflow training make it easier for internal teams to keep building after launch. |
| 4. Halo Lab | B2B SaaS companies relaunching their brand and website together. | Quote-based, not publicly available | Brand + website together. Branding, UX, website design, development, copy, and SEO can all sit under the same engagement, making it a fit for a broader repositioning. |
| 5. Saasfactor | SaaS, AI, and fintech products trying to improve onboarding, activation, and signup flows. | $15,000 redesign; $6,000/mo retainer | Product activation. Focuses on what happens after someone signs up, using product data and user behaviour to improve onboarding, activation, and time to value. |
1. GrowUp
Best For: B2B SaaS companies in complex categories such as Fintech, HR Tech and Ed Tech, where the website has to explain a sophisticated product, serve multiple stakeholders, and contribute to organic growth and pipeline.
GrowUp is a B2B SaaS website agency built on two ideas. First, complex software rarely gets understood from a feature grid, so the site should be built around the story of the product. That often means explaining it creatively: through a person, a workflow or a working interface rather than a list of capabilities.
Second, we don’t treat design and search as separate disciplines. Because GrowUp also runs dedicated B2B SaaS SEO and AI-search programs, organic visibility is engineered into the site architecture from day one.
The result is a website designed to communicate the product clearly, earn visibility, and support demand generation. GrowUp’s SEO work has generated $4.7M+ in content-influenced pipeline.
Featured project: Origin Benefits
Origin is an enterprise benefits intelligence platform. It gives multinational HR teams one searchable record of every benefit, cost, vendor and country, with an AI engine, Cuido, that reads policies, contracts and vendor data in any language.
For an enterprise product like Origin, the homepage has to satisfy two different questions: “What does this actually do?” and “Why should we believe it?”
The walkthrough answers the first: a five-slide sequence, built in code, that follows a fictional employee, Priya, as she uses Cuido to navigate her benefits. The customer evidence and impact data answer the second, further down the page, for the HR and finance stakeholders who actually sign the contract.
Featured project: Capsa
Capsa is an AI operating system for private capital. It connects the data a fund already holds, including CRM, email, documents and third-party sources, into one searchable layer, then runs diligence and investment-committee workflows across the deal lifecycle.
For an AI platform like Capsa, no amount of copy convinces a sceptical investor. They need to see the AI actually working.
So the homepage opens on a live-feeling diligence workspace: a real deal folder, connected sources on one side, an AI-generated answer with citations in the middle, and a workflow tracker on the right.
Underneath, we animated the rest of the platform the same way, sourcing, diligence, committee and monitoring, each its own working screen: an investor typing a mandate, Capsa comparing a deal against precedents, a memo being drafted with benchmarks and citations attached.
If these examples feel close to what you want for your own site, tell us a little about your product and who you want to reach. We can help you work out what the site needs to explain and how to give it a design that feels like your company.
Pricing
- 5-Week Website Design Sprint, from £8,500. A fixed-scope website design and build covering five pages, from strategy and UX through to design, development and launch. Optional conversion copy: +£3,000.
- 3-Day Landing Page Design Sprint, £2,500. A focused sprint for one launch-ready page, including design, responsive build, kickoff and review. Optional conversion copy: +£1,000.

Make your website as credible as the product behind it.
The sprint covers site structure, five page wireframes, custom UI, reusable components, development, tracking, and QA.
2. Webstacks
Best For: B2B SaaS teams running several product lines, audiences or languages, with engineers who can work in a headless stack.
Webstacks describes itself as a composable web agency for B2B tech, and it is a listed Sanity agency partner. Its services include composable website redesigns, CMS migrations, design systems, and ongoing website product-team retainers.
Featured project: Gong
Gong, the revenue AI platform, had outgrown its WordPress setup. Years of plugins and manual workflows made even routine website changes slow, so Webstacks moved the site to a composable architecture powered by Sanity.
Instead of taking the entire site offline for one huge rebuild, they started with the homepage, navigation, and core solutions pages. That first phase established the new design system, content structure, and CMS before extending the approach across the wider site.
Worth studying if you’re dealing with a large B2B SaaS site and can’t afford a big-bang launch.
Pricing:
Not publicly available. Webstacks scopes each project individually, and independent reviews describe the pricing as premium. As a market reference, one 2026 agency guide puts enterprise replatforms at $90,000 upward.
3. Brix Agency
Best For: SaaS startups wanting custom Webflow design without traditional development delays.
BRIX Agency is a Webflow design and development agency that has been building since 2015, focused on B2B software, SaaS, and tech startups.
Every site is built from modular, reusable sections, so your team can create new pages without starting from scratch, and each project ends with a two-hour Webflow training session. Its services cover custom Webflow design and development, animations, and integrations with the tools you already use, such as Slack and email platforms.
Featured project: CertifID
CertifID, a wire-fraud prevention and funds-protection company for real estate transactions, brought BRIX in to redesign its website and move it from WordPress to Webflow.
The project covered the full site experience, including web design, development, custom icons and graphics, and HubSpot implementation. The client also noted that the team stayed professional and ahead of schedule throughout the project.
Pricing:
From $10,000 per project, quoted by scope. A typical Webflow build takes four to eight weeks depending on the number of pages, and Webflow hosting is billed separately, which BRIX puts at roughly $25-$100/mo depending on the plan.
4. Halo Lab
Best For: B2B SaaS companies rebranding and relaunching their website together, with brand identity, website design, and build handled by one agency.
Halo Lab is a design and development agency that covers SaaS website design, landing pages, website redesigns, UI/UX design, branding, and design systems under one roof. Because the same team designs product interfaces and marketing sites, the website can share the visual language of the product. On the build side, it works in Webflow, and in headless CMSs such as Sanity and Prismic with Next.js and React for custom builds.
Featured project: Pluto
Pluto is a UAE-based spend-management platform combining corporate cards, reimbursements and procure-to-pay workflows. Its tools already solved real finance-team problems, but the brand felt cold.
Halo Lab ran workshops, research and competitor analysis to build a human-first strategy around clarity, trust and emotional connection, then carried it through brand identity, website strategy and design, Webflow development, copywriting, SEO foundations, motion and custom scripts.
Pricing:
Quote-based, with no published rates. Halo Lab prices each project on complexity, speed, and quality, and the budget bands on its quote form run from $10,000–$20,000 up to $100,000–$200,000.
5. Saasfactor
Best For: SaaS, AI and fintech teams needing onboarding, activation and sign-up flows redesigned on a fixed timeline.
Saasfactor is a SaaS product design agency, so its work sits closer to the product than to the marketing site. It starts by finding where users drop off using analytics, behaviour data, and support feedback, then redesigns the key flows, such as onboarding and activation, and tests them with real users against the current design.
Featured project: BizReply
BizReply is an AI tool that helps brands find online conversations worth joining.
Saasfactor redesigned the onboarding and dashboard around a simple goal: helping new users find something useful as quickly as possible. Instead of opening with a list of features, onboarding starts with the problem users came to solve. The dashboard then turns weekly activity into a clear summary rather than a wall of numbers.
Saasfactor reports a 53% increase in onboarding completion and a 32% increase in feature usage, while time to first value dropped from 8.5 minutes to 3.2.
Pricing:
Published on its site. The fixed-price UX Redesign is $15,000, delivered in 60 days with a results guarantee, and the Team Retainer is $6,000 per month, with the option to pause or cancel anytime.
How to Shortlist the Right B2B SaaS Web Design Partner
Before you choose a web design agency for your B2B SaaS, decide what the project has to deliver. Some agencies build fixed-scope marketing sites, others specialise in headless builds, brand and website together, or product flows.
Use the questions below to narrow the list based on your goals and budget.
What does the project need to deliver?
- A complete website or one high-stakes page: Choose GrowUp for a fixed-fee sprint covering strategy, UX, design, and build.
- Brand and website together: Choose Halo Lab if you’re relaunching your site and want brand identity, website design, and build from one agency.
- Product flows rather than the marketing site: Choose Saasfactor if the priority is onboarding, activation, and sign-up flows.
Which platform and architecture fits your team?
- Webflow with reusable sections: Choose Brix Agency if you want a custom Webflow build made from modular sections, plus a training session so your team can edit and extend the site.
- Headless or composable stack: Choose Webstacks if you run several product lines and have engineers who can work in a headless setup. Halo Lab also builds custom sites on Sanity and Prismic.
- Your existing CMS: Choose GrowUp if you want the site rebuilt on Webflow, WordPress, Framer, or a headless stack, in most cases on the CMS you already use so your content structure and URLs stay intact.
What's your budget and how much flexibility do you need?
- £2,500–£11,500+ per project: GrowUp offers fixed-scope sprints in this range, including optional conversion copy.
- $10,000+ per project: Brix Agency quotes from this level, with typical builds taking four to eight weeks depending on page count.
- Custom or enterprise scope: Webstacks and Halo Lab charge between $10,000 and $200,000, with full enterprise replatforms routinely starting at $90,000 upward.
What Makes a B2B SaaS Web Design Partner Worth Hiring in 2026
There is a lot more to choosing a web design agency than finding good-looking work. The real questions are whether they understand SaaS, can make a complicated product easy to navigate, can work with your existing stack, and have a clear plan for getting from first brief to launch.
That is what we built GrowUp around. We work in defined five-week sprints, with strategy, UX, design, development, tracking, and QA handled together rather than passed between separate teams.
