Best Banking-As-A-Service (BaaS) Platforms In 2027

Last updated: November 2026

Quick answer: For banking-as-a-service in 2027, US fintechs should look at Column and Cross River for direct bank partnerships, Unit, Treasury Prime and Synctera for developer platforms on top of partner banks, and Galileo for processing at scale. In Europe, Solaris, Swan, Railsr and Griffin offer embedded accounts, cards and payments. After several US sponsor-bank enforcement actions, how a BaaS provider handles compliance matters as much as its API.

Which products do you need?

Accounts, cards, payments, lending and international coverage vary widely between providers.

What if the provider fails?

Ask about fund safeguarding and migration plans.

Your team or a partner; see fintech software development companies.

What changed after recent sponsor-bank enforcement actions?

Banks now expect stronger compliance from fintech partners, and onboarding takes longer.
