1. GrowUp
Best For: B2B FinTech, WealthTech, and financial infrastructure companies that need strategy, UX, copy, design, development, and SEO handled in one project.
GrowUp is a B2B FinTech and SaaS web design agency built around two ideas:
- Complex financial products are bought through trust and clarity. FinTech buyers, whether retail depositors or enterprise CFOs, need to see how the platform works, where capital flows, how yield or savings are generated, and how security is guaranteed
- The website needs to be built for discovery as well as conversion. GrowUp runs dedicated B2B FinTech SEO and AI-search visibility programs, so search architecture, structured data, and high-intent conversion paths are considered from the start rather than added after the design is finished.
The result is a website that makes complex financial products easy to understand, gives buyers confidence, and turns organic traffic into opportunities.
Featured project: Capsa
Capsa is an AI operating system for private capital, built for investment teams managing sourcing, diligence, investment committees, and portfolio monitoring. It connects CRM, email, documents, and third-party financial data, then brings that information into one searchable workspace.
For private-capital buyers, the website needed to do more than explain AI. It had to make the underlying investment workflows tangible and show how Capsa fits into the way an investment team actually evaluates deals.
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 an investment workflow tracker on the right.
We carried the same approach through the rest of the site, showing sourcing, diligence, committee and monitoring as working investment workflows rather than abstract product features.
Featured project: Tumelo
Tumelo gives investors in pooled funds a direct role in eligible resolutions, while giving fund managers and institutional investors the systems to manage voting policies, proxy research, investor instructions, and audit trails.
The site’s central task was to prove the platform actually reconciles votes accurately at scale, since that’s the specific thing a stewardship team or compliance officer would need to see before trusting it with fiduciary decisions.
The homepage does this with a working example rather than a description: a pooled fund with £2.4B in AUM, a routing breakdown of how 2,000+ investors' policies split across a resolution, and that resolution reconciled to a final tally (68.4% for, 31.6% against) marked 100% auditable.
Each audience also gets a dedicated section built around their actual use case: fund managers on retaining control of unallocated votes, institutions on applying policy across holdings, and retail investors on getting a say without giving up pooled-fund diversification.
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.

Featured project: Upvest
Upvest is a Berlin-based investment API platform that enables B2B financial institutions to offer fractional trading, ETFs, and digital assets.
Upvest needed a brand and website that reflected its goal of becoming the technological backbone for European capital market access.
Design by Structure developed the positioning framework (“One API. Any investment experience.”), streamlined technical jargon into straightforward messaging, created a distinct color and icon hierarchy for different asset classes, and built a modern web experience showcasing API functionality.
Pricing:
Quote-based. Enterprise brand and digital site redesigns typically range from £25,000 to £90,000+ depending on positioning depth and CMS requirements.
3. Halo Lab
Best For: FinTech scale-ups relaunching their brand identity and web presence together under one unified engagement.
Halo Lab is a full-service design and development agency that bridges digital product UI/UX and web design. Because their designers work on both financial application interfaces and marketing sites, they maintain a consistent visual and interaction language between what a user sees on the marketing site and what they experience inside the software.
Featured project: Pluto
Pluto is a UAE-based corporate spend management platform providing corporate cards, expense reimbursements, and procure-to-pay workflows across the MENA region.
While Pluto solved critical finance team bottlenecks, its original site felt corporate and impersonal. Halo Lab conducted stakeholder workshops to build a brand identity centered on trust, speed, and modern financial management. They carried this identity through copywriting, Webflow engineering, 3D motion elements, and structured SEO foundations.
Pricing:
Quote-based. Project budgets typically start at $10,000–$20,000 for focused scope and scale up to $100,000+ for complete brand, design system, and multi-page web builds.
4. Brix Agency
Best For: FinTech and financial security startups seeking custom Webflow builds with modular systems for fast internal growth.

Every site is built using modular, reusable layout sections, enabling internal marketing teams to spin up new landing pages or regulatory landing pages without needing ongoing developer assistance.
Featured project: CertifID
CertifID is a wire-fraud prevention and funds-protection platform designed to secure high-value real estate transactions.
CertifID brought in BRIX Agency to migrate their website from WordPress to Webflow while updating their visual identity. BRIX delivered a complete site experience—including custom security graphics, risk mitigation iconography, HubSpot marketing integrations, and a structured Webflow component library backed by hands-on team training.
Pricing:
Starts at $10,000 per project. Most custom Webflow builds take 4 to 8 weeks. Webflow CMS hosting is billed separately (typically $25–$100/month).
5. Tubik Studio
Best For: Open banking platforms, paytech, and trading platforms requiring custom UI/UX, motion, and complex data visualisation.
Tubik Studio is a design agency known for custom illustrations, motion design, and UI/UX for complex web platforms. They excel at converting abstract financial concepts, like API data routing, clearing mechanisms, or algorithmic trading, into engaging visual systems.
Featured project: Crezco
Crezco is a UK open banking payment API that facilitates free, instant account-to-account bank transfers.
As Crezco evolved from a small business payment tool into a developer-focused API infrastructure, Tubik Studio redesigned their digital identity and web presence. Tubik created abstract, technical visual metaphors representing real-time payment rails and bank integrations, helping technical buyers grasp Crezco's clearing speed and security model instantly.
Pricing:
Quote-based depending on custom graphics, animation complexity, and product UI/UX scope.
How to Shortlist the Right B2B SaaS Web Design Partner

How much technical complexity does the website need to handle?

- API or financial infrastructure: Design by Structure has specific experience positioning technical finance products such as investment APIs for institutional buyers.
- Complex product visuals and interaction: Tubik Studio is a stronger fit when custom UI, motion, illustration, and data visualisation are a significant part of the brief.
What does your internal team need the agency to own?
- Strategy through launch: GrowUp handles strategy, UX, copy, design, development, and SEO within one website engagement.
- Design and development: Brix Agency is suited to teams that already have their positioning and messaging in place but need a custom Webflow build and reusable CMS components.

What level of investment fits the project?
- £2,500–£11,500+: GrowUp offers focused landing-page and website sprints, with optional conversion copy.

What Makes a FinTech Web Design Partner Worth Hiring in 2026
The right FinTech web design partner needs to understand more than visual design. They need to get the product, the buying process, the audiences involved, and the level of trust required before someone commits capital, adopts the technology, or brings it into their organisation.
GrowUp brings those disciplines together in a defined five-week process. Strategy, messaging, UX, design, development, tracking, and QA are handled as one project, so the final website reflects both the product and the commercial case for choosing it.
