How to Build a Fintech App Without a Money Transmitter License

The Licensed Infrastructure Stack

Stripe handles card payments and PCI compliance. Plaid handles bank account linking and financial data access. Unit or Synapse provides banking-as-a-service (accounts, ACH, wires). Persona or Stripe Identity handles KYC. You build the product layer on top — UX, business logic, and customer relationships. The licensed provider handles regulatory compliance for their layer.

• Payments: Stripe (cards), Stripe Connect (marketplace payouts)
• Bank linking: Plaid (read data), Plaid Transfer (initiate ACH)
• Banking: Unit, Synapse, Treasury Prime (BaaS)
• KYC: Stripe Identity, Persona, Jumio
• Lending: not DIY — partner with a licensed lender

What You Can Build Without a License

Personal finance dashboards (read-only via Plaid), payment collection apps (Stripe), marketplace with seller payouts (Stripe Connect), subscription billing (Stripe Billing), investment tracking (read-only market data), budgeting apps, and B2B invoicing. What requires a license or licensed partner: holding customer deposits, lending money, money transmission between users, and crypto exchange.

KYC Is Your First Compliance Step

Any app that moves money needs to verify user identity. For MVP, Stripe Identity ($1.50/verification) or Persona handles document verification and selfie matching. Collect: legal name, DOB, address, government ID. Store verification status, not raw documents. This satisfies AML requirements for most fintech MVPs.

When You Actually Need a License

If your business model requires holding customer funds (not just passing through Stripe), operating as a lender, or transmitting money between users without a licensed intermediary — you need an MTL or a banking partner. MTL costs $5K–$500K per US state and takes 6–18 months. At MVP stage, restructure to use licensed partners instead.

Our Fintech MVP Approach

We build fintech MVPs on Stripe + Plaid + Supabase in 4–6 weeks. KYC via Stripe Identity, payments via Stripe, bank linking via Plaid, data in encrypted Postgres with audit logs. Fixed price from $5,800 for fintech complexity. You launch, validate, and raise — then decide if you need your own license or continue on infrastructure.
