-
US Est. 2014 Active Backend-as-a-Service

Our Verdict

Full-stack banking APIs that move fast but carry real sponsor-bank and regulatory risk you must underwrite.

Pros

  • BaaS with accounts, cards, and ACH in one API
  • Handles KYC/AML compliance workflows
  • Sponsor bank relationships abstracted away
  • Ledger primitives for fintech apps

Cons

  • Regulatory incidents caused fund freezes historically
  • Onboarding and underwriting can take weeks
  • Pricing opaque without sales call
  • Platform risk concentrated on sponsor bank
Best for: Fintech startups needing accounts, cards, and ACH under one compliance umbrella Not for: Teams that need multi-bank redundancy or cannot tolerate BaaS concentration risk

When to Use Synapse

  • Banking-as-a-service for building neobanks and fintech products
  • Account opening, ACH, and wire payments via a single API
