Buyer's Guide
Best FinTech Development Companies (2026)
Your banking API integration shouldn't take longer than your seed round.
We evaluated 30+ fintech development companies on payment processing expertise, regulatory compliance (PCI DSS, SOC 2, PSD2), banking API integration depth, and production track record. Here are the 8 that ship compliant fintech products.
Transparency: 1Raft is our company. We've listed ourselves at position #4. FinTech is one of our strongest verticals, but we specialize in product-scale fintech - not institutional trading platforms or capital markets systems.
Building fintech is uniquely hard. Payment processing, multi-currency support, regulatory compliance across jurisdictions, and banking API integration (Plaid, Stripe Connect, Open Banking) require specialized knowledge that general-purpose agencies don't have. This guide evaluates companies on fintech-specific capabilities, not just engineering skill.
How we evaluated
We reviewed each company's fintech-specific case studies, verified PCI DSS and SOC 2 compliance claims, and evaluated banking API integration experience across 30+ companies. We also spoke with 6 fintech founders who hired development partners in the past 12 months.

PCI DSS, SOC 2, PSD2, KYC/AML - does the company build compliance into the architecture, or treat it as a checkbox?

Frequently asked questions
Three factors: regulatory compliance (PCI DSS, SOC 2, KYC/AML), financial data security (encryption, tokenization, audit trails), and third-party integrations (banking APIs, payment processors, credit bureaus). A good web agency can build you an app, but handling money requires specialized knowledge.
