Ranked agencies for B2B clients
Top 30 of 85 agencies with documented B2B work.
About this list
B2B fintech is a different design problem from consumer money apps: the products are payment infrastructure, banking-as-a-service, treasury, risk and compliance tooling — bought by businesses and often operated by developers or finance professionals. This is the largest B2B-by-industry pool in the directory (82 agencies). Overnice documents product UI for crypto and dev-infrastructure companies; Method evidences strategy-through-engineering for Jenius Bank; Supercharge names regulated modernization for OTP and MOL.
The roster spans Western prestige and Central-European value, with Warsaw, London and Berlin holding the largest concentrations. Rates run €23–200 per hour — the widest band of any B2B vertical.
Triage by who actually uses the product. A developer-facing payments API, a treasury dashboard and a compliance tool reward different instincts — API docs and integration UX versus dense data views versus audit-trail rigor. Read each profile's documented B2B fintech clients for the specific product form you're building, and note the embedded-team models that suit integrating designers into a regulated engineering org.
Expert Insight
Why FinTech experience matters
Regulatory knowledge—PSD2, KYC, and AML aren't just acronyms; they are hard constraints that break standard design patterns. Specialists know how to design compliant flows that don't kill conversion. A generalist will design a 'clean' onboarding that gets rejected by your compliance team on day one—costing you €30k and 8 weeks
Trust engineering—Users judge 'security' by visual cues. If your app looks too trendy or 'startup-like,' users won't connect their bank accounts. Specialists have tested with real banking users and know the exact visual balance between modern and 'bank-grade.' One wrong font choice can drop trust scores by 25%
Complex data visualization—Dashboards, transaction histories, and P&L views require high-density information design, not just whitespace. Generalists often over-simplify data until it's useless for power users who spend 4+ hours a day in these tools. The result? They export to Excel and your product becomes a glorified login screen
Onboarding friction—KYC requires asking for passports and tax IDs immediately. Specialists know how to sequence these high-friction requests to minimize the 40%+ drop-off rates common in fintech. The difference between asking for ID on step 2 vs. step 5 can be worth €200,000 in annual revenue for a mid-size neobank
