The failure of fintech middleman Synapse left customers unable to access savings and exposed gaps in the records banks rely on to track consumer money.
A Maryland teacher’s complaint to a federal bankruptcy court in California captured the human cost of a fintech failure that had already become a warning for banks: nearly $38,000 in savings, he said, was trapped in a Juno account that he could not access. The app relied on technology from Synapse Financial Technologies, a middleware provider that had entered bankruptcy weeks earlier, and his case was one of many that exposed how fragile consumer balances can become when banking-as-a-service arrangements break down. According to CNBC and TechCrunch, Synapse had become a central but largely invisible layer in a system that connected fintech apps to partner banks, while leaving no single firm with a complete view of customer balances.
Synapse sat between the front-end apps used by consumers and the banks that actually held deposits. In practice, that meant the company handled account infrastructure, transaction processing and ledger management for a reported large network of fintechs and millions of users. TechCrunch reported that Synapse laid off staff in 2023, filed for Chapter 11 in April 2024 and later saw a proposed sale collapse. That unraveling triggered a more fundamental problem: records held by Synapse could not be reconciled with those of its banking partners, leaving customers unable to get at money that the app systems still appeared to show as theirs.
The Consumer Financial Protection Bureau later alleged that Synapse failed to keep adequate records of consumer funds and that the mismatch between its ledgers and the banks’ books left a shortfall of between $60 million and $90 million. In August 2025, the bureau said it had taken action against Synapse under the Consumer Financial Protection Act and obtained a stipulated final judgment that included a nominal civil money penalty and restrictions on the sale of customer information. The bureau’s case did not decide every factual question in the wider dispute, but it underscored how central recordkeeping failures were to the collapse.
The legal fallout spread quickly. Customers of the Yotta and Juno apps filed a proposed class action in Colorado against four banks tied to Synapse’s programmes, arguing that the banks failed to safeguard consumer funds and maintain reliable records. Another proposed class action in Tennessee against Evolve Bank & Trust and Lineage Bank was later transferred to Colorado and consolidated with the first case. Separately, Yotta sued Evolve in federal court in California, but a judge dismissed the complaint because Synapse was a required party that could not be joined while in bankruptcy. That ruling did not decide whether Evolve was liable, but it showed how essential Synapse’s records were to any attempt to sort out responsibility.
For banks, the lesson is broader than Synapse. Third-party arrangements do not erase a bank’s duty to operate safely and soundly or to comply with the law. Federal regulators’ 2023 third-party risk guidance says banks must address those risks from planning through termination, and the proposal issued in September 2026 to replace that guidance with a shorter principles-based document did not change the underlying statutory obligations. The practical question is still the same: if a vendor disappeared tomorrow, could the bank identify what it owes each customer? In fintech partnerships, that means testing reconciliation, data access, audit rights, backup records and exit plans before a problem becomes a bankruptcy.
