“Can a digital community bank become the infrastructure backbone for fintech companies by offering API-first BaaS and cross-border payment capabilities?”
Radius Bank evolved from a traditional community bank into a forward-thinking digital bank and Banking-as-a-Service provider based in Boston. The bank built an API-first infrastructure layer, partnering with Treasury Prime to offer commercial API banking to fintechs and developers, and with Currencycloud for cross-border payments. In February 2020, LendingClub announced its acquisition of Radius Bancorp for $185 million — a landmark deal that made LendingClub the first U.S. online lender to acquire a bank charter, effectively subsuming Radius into LendingClub Bank.
