Synapse Financial Technologies, Inc. was an American banking as a service company.

Based in San Francisco, Synapse filed for chapter 11 bankruptcy protection in April 2024.

[2][3] Synapse claimed to keep customer deposits in FDIC insured bank accounts, and argued that this provided a comparable level of depositor protection to conventional bank accounts.

[5][6] Following the bankruptcy declaration, "tens of thousands of U.S. businesses and consumers" lost access to Synapse's services, leaving questions as to the location of funds.

[4][8] The CEO of Yotta Savings – a fintech company which relied on Synapse to manage customer deposits – released financial data in November 2024 showing that 13,725 former customers lost deposited money due to the Synapse bankruptcy.
