Overview
Synapse Financial Technologies, Inc. was a San Francisco-based American banking-as-a-service company founded in 2014 by Sankaet Pathak and Bryan Keltner. It developed infrastructure intended to let financial-technology companies offer banking, payments, deposit, card, and related financial products without building a complete regulated banking stack themselves. Synapse operated as a technology and program-management intermediary rather than as an insured bank. Its model connected fintech clients with partner banks and other financial institutions, while Synapse supplied software, APIs, operational processes, and compliance-related infrastructure. The company presented its platform as a way for fintech applications to place customer funds in accounts at FDIC-insured partner banks. That arrangement could provide pass-through protection under applicable conditions, but Synapse itself was not an FDIC-insured bank. Consequently, the company’s own bankruptcy did not carry the same direct depositor protection as the failure of an insured depository institution. This distinction became central to the disruption that followed the company’s collapse. Synapse attracted venture backing, including investment from Andreessen Horowitz, and reported raising $51 million. Its business relationships included approximately 100 fintech companies, among them Dave and Honey, and the company stated that its partners collectively reached roughly 10 million retail customers. In 2022, it was described as one of the fastest-growing financial-services companies in the United States. The company reached unicorn status in 2024, but its growth was accompanied by mounting operational and governance concerns. Reference material describes discrepancies between Synapse’s ledgers and partner-bank records, and reports that the board discussed removing chief executive Sankaet Pathak in 2023. Investors from Andreessen Horowitz opposed that move. Synapse filed for Chapter 11 bankruptcy protection in April 2024. The filing interrupted services used by many fintech companies and left tens of thousands of businesses and consumers unable to access financial products connected to Synapse’s platform. The bankruptcy also generated uncertainty over the reconciliation and location of customer funds. In May 2024, Jelena McWilliams, a former chair of the Federal Deposit Insurance Corporation who had been appointed as bankruptcy trustee, reported an estimated shortfall of between $65 million and $96 million between Synapse’s records and the records held by its partner banks. The consequences were particularly visible among customers of Yotta Savings, a fintech company that had relied on Synapse to manage deposits. Financial information released by Yotta in November 2024 indicated that 13,725 former customers had lost access to deposited funds following the bankruptcy. The reported deposits totaled $64.9 million, while approximately $11.8 million had been refunded at that point. A lawsuit seeking class-action status was also reported against four banking partners: Evolve Bank & Trust, AMG National Trust Bank, American Bank North America, and Lineage Bank. Synapse’s history illustrates both the promise and structural fragility of embedded-finance infrastructure. Its platform helped consumer-facing fintechs launch products rapidly by outsourcing important banking and payment functions. At the same time, the bankruptcy exposed the dependence of customers on accurate ledger reconciliation, clear allocation of responsibilities among technology companies and banks, and effective oversight of non-bank intermediaries. Synapse was no longer operating as an independent active company after its 2024 bankruptcy filing.
History
Synapse was established in 2014 by Sankaet Pathak and Bryan Keltner as a banking-as-a-service platform. Its objective was to provide the software and institutional connections required by fintech companies seeking to offer deposit accounts, payments, cards, and related services. Rather than operating as a conventional bank, Synapse worked with partner banks and positioned itself as a technology and infrastructure provider. The company’s model reflected the growth of embedded finance in the United States. Consumer applications could use Synapse’s APIs and operational systems while relying on partner banks for regulated banking functions. Synapse stated that customer deposits were held at FDIC-insured banks, although Synapse itself was not an insured bank and therefore did not provide direct FDIC protection against its own insolvency. The distinction between bank insurance and the financial condition of a non-bank intermediary later became a defining issue in the company’s collapse. Synapse obtained venture investment, including backing from Andreessen Horowitz, and raised $51 million according to the available reference material. It reported business relationships with about 100 fintech companies, including Dave and Honey, and claimed that those relationships indirectly reached approximately 10 million retail customers. The company was recognized as one of the fastest-growing financial-services companies in the United States in 2022 and attained unicorn status in 2024. Operational and governance concerns emerged as Synapse expanded. Reports described discrepancies accumulating between the company’s internal ledgers and information held by banking partners. In 2023, the board reportedly considered removing Pathak as chief executive, but Andreessen Horowitz investors argued against the change. Former employees also described Pathak’s management style as volatile and autocratic and alleged that inexperienced employees, unreliable technology, and an unprofessional workplace contributed to customer departures and operating problems. These accounts are allegations and descriptions reported in external sources rather than a formal finding in this dossier. Synapse filed for Chapter 11 bankruptcy protection in April 2024. The filing interrupted services for fintech businesses and consumers that depended on its platform. Customers and counterparties faced uncertainty about the location and ownership of funds because records maintained by Synapse did not fully align with records maintained by partner banks. Jelena McWilliams, appointed as bankruptcy trustee, stated in May 2024 that the discrepancy was estimated at $65 million to $96 million. The disruption affected users of Yotta Savings, whose deposit program relied on Synapse. In November 2024, Yotta released information indicating that 13,725 former customers had lost deposited money. The disclosed deposits amounted to $64.9 million, while $11.8 million had been refunded. Legal action was also reported against four banking partners, with plaintiffs seeking class-action treatment for losses connected to the breakdown. Synapse’s bankruptcy ended the company’s role as an independent operating fintech infrastructure provider. Its collapse became a prominent example of the risks created when consumer financial products depend on layered relationships among fintech applications, non-bank technology intermediaries, and regulated banks. It also highlighted the importance of ledger controls, reconciliation, custody transparency, contractual allocation of responsibility, and oversight of banking-as-a-service arrangements.

Products and positioning
Synapse positioned itself as the infrastructure layer between regulated financial institutions and consumer-facing fintech companies, enabling partners to launch banking and payment products through software, APIs, and bank-program relationships.
Banking-as-a-service infrastructure · 2014
Synapse Banking-as-a-Service Platform
Synapse’s core platform supplied software, APIs, operational tooling, and connections to partner banks so fintech companies could provide banking-style products to their own customers. The platform was designed to abstract some of the complexity of account administration, payments, card programs, and financial operations. Synapse did not itself function as an FDIC-insured bank; regulated banking services were provided through banking partners.
Fintech account infrastructure
Deposit and Account Infrastructure
Synapse supported fintech deposit and account programs by coordinating technology and relationships with partner banks. Its model allowed customer-facing companies to present account products while funds were intended to be held through participating insured institutions. The later bankruptcy exposed the importance of accurate customer ledgers and reconciliation among Synapse, its fintech clients, and the banks holding funds.
Payments and card-program services
Payments and Card Infrastructure
Synapse provided infrastructure used by fintech companies for payment and card-related products. These capabilities were part of the broader banking-as-a-service stack and were intended to let partner companies launch consumer financial features without independently assembling every technology and banking relationship. The available reference material does not identify individual card products or product names.
