Banking-as-a-Service (BaaS)

By Paul Brock·Updated on 22-04-2026
TL;DR

Banking-as-a-Service is infrastructure letting non-bank companies offer banking features (accounts, cards, payments) to their users via APIs.

BaaS providers (Solaris, Swan, Weavr, Modulr) themselves hold a bank or e-money licence and make their regulatory infrastructure available via APIs to non-banks. Those 'embed' banking services into their own product. Result: a fitness app offers payment accounts to members without being a bank; a marketplace gives sellers their own IBANs without a licence.

Example

A Dutch SaaS for online service providers integrates Swan's API: each user automatically gets an IBAN, debit card, and payout account. Swan handles compliance, SaaS builds UX — win-win.

Frequently asked questions
