What affects the timeline

Money transmission licensing

If you're moving money directly, you may need a Money Transmitter License (MTL) — $5K–$500K and 6–18 months to obtain per US state. Most fintech MVPs use a licensed partner (Stripe, Synapse, Unit) to avoid this.

KYC requirements

Basic KYC (name, DOB, address): 1–2 days with Stripe Identity. Enhanced KYC (ID document + selfie): 3–5 days. AML screening: 1 week.

Banking integrations

Plaid (bank account linking): 1–2 weeks. ACH payments via Stripe: 1–2 days. Wire transfers or FX: 2–4 weeks. Crypto on-ramps: 1–2 weeks.

Frequently asked questions

Do I need to be a licensed financial institution?

Not necessarily. By building on licensed infrastructure (Stripe for payments, Plaid for data access, Unit for banking-as-a-service), you can launch a fintech product without a money transmitter license. Consult a fintech lawyer early.
