Synapse

Founded in 2014 by Sankaet Pathak, Synapse Financial Technologies began as a provider of developer APIs that allowed fintech companies to embed banking services — including deposit accounts, payments, and lending — directly into their products. The firm operated as a crucial intermediary layer between partner financial institutions, notably Evolve Bank & Trust, and prominent fintech clients such as Juno (formerly OnJuno), Yotta, and Mercury. Synapse raised over $50 million across multiple rounds from investors including Andreessen Horowitz and Trinity Ventures, positioning itself as a core infrastructure provider in the so-called embedded finance ecosystem (per PitchBook and the firm's regulatory filings, 2019-2023). Synapse's strategy centered on its proprietary ledger system, which it used to track end-user account balances and transactions across its network of bank partners. Unlike traditional processors, Synapse did not hold the underlying deposits itself. Instead, it maintained an operational ledger that theoretically matched the deposit records held at each partner bank. This intermediation model allowed digital banking apps to enter the market without acquiring their own bank charters. By 2023, the firm claimed to serve over 10 million end users on its platform. Transaction volume was driven by consumer-facing fintechs offering high-yield savings accounts secured through Synapse's brokerage sweeps program and its network of FDIC-insured institutions. At its peak, Synapse employed approximately 150 professionals with its primary office in San Francisco. A series of cost-cutting measures in 2023, including rounds of layoffs, preceded the firm's terminal crisis. The Board terminated Pathak as CEO in early 2024, a decision the founder publicly opposed and litigated. In April 2024, Synapse filed for Chapter 11 bankruptcy protection in the Southern District of New York. The filing ignited a dispute between the shuttered service provider and its bank partners, particularly Evolve Bank & Trust, over a critical operational question: the accuracy of Synapse's bespoke ledger versus the banks' internal deposit records. The structural differentiator underpinning Synapse's collapse was its position as a non-bank ledger keeper for FDIC-insured products. Unlike a full-stack chartered bank, Synapse could fail without directly triggering FDIC receivership, leaving end-user funds frozen in a jurisdictional gray zone. When the company shut down, fintech partners and regulators discovered that the balances recorded in Synapse's proprietary system did not reconcile with the cash held at partner banks. An estimated shortfall between $65 million and $95 million emerged — representing consumer deposits that appeared on fintech apps but could not be located in the physical banking system (per court filings and coverage, 2024). This architecture, initially sold as a frictionless way to build banking products, ultimately demonstrated the systemic risk of synthetic ledger-based models operating outside direct prudential oversight.
