Synapse: the fintech plumbing failure that froze thousands of people's savings
Synapse sat between consumer fintech apps and partner banks, keeping the ledgers that recorded whose money was whose. When it collapsed in 2024, those records didn't reconcile with bank balances, freezing funds for more than 100,000 people and revealing a shortfall of tens of millions of dollars.

What happened
Filed for bankruptcy in April 2024. More than 100,000 end users had funds frozen, and a court-appointed trustee found a shortfall reported at up to $96 million between what banks held and what users were owed.
What Synapse was
Sankaet Pathak founded Synapse in 2014 to provide banking-as-a-service infrastructure. Fintech apps used it to offer accounts and cards, while partner banks such as Evolve Bank & Trust held the deposits.
After disputes with partners and the loss of major clients, Synapse filed for bankruptcy in April 2024. Access to around $265 million in deposits was frozen, and the trustee found that bank holdings fell short of what end users were owed.
Why it failed
- 1
Ledgers that didn't reconcile
Customer money was pooled in accounts at partner banks, and Synapse's records of who owned what didn't match the banks' balances. Without accurate, reconciled ledgers, nobody could say exactly who was owed what.
- 2
Unclear responsibility across layers
Users dealt with a fintech app, which relied on Synapse, which relied on banks. When something went wrong, each layer pointed to another, and customers were stuck in between.

Misplaced faith in deposit insurance
Many users believed their money was FDIC-insured, but pass-through insurance depends on accurate records and doesn't cover the failure of a non-bank middleman.
The product lesson
In financial products, the boring infrastructure — reconciliation, audit trails, clear ownership of funds — is the product. If you build on a third-party platform, know where the money actually sits, who keeps the ledger, and what happens if a partner fails. Customers will hold you responsible either way.
Early warning sign to watch for
Daily reconciliation between your ledger and the bank's balances shows unexplained differences that keep being deferred.
