Formance

Formance provides an open-source, programmable infrastructure designed for fintech companies, marketplaces, and large-scale vertical SaaS platforms to build and operate complex financial applications. Founded in 2021 by Clément Salaün and Anne-Sybille Pradelles, the company is headquartered in Paris, France, with a growing presence in the US. The company's creation was driven by Salaün's experience as the former payments lead at Selency, where he identified the need for a robust system to manage intricate money flows between pay-ins and payouts—a component he had to build from scratch. Pradelles, formerly the COO of cybersecurity firm Alsid, brings expertise in scaling a technology company from its early stages to a successful acquisition.

Formance participated in the Y Combinator accelerator program in the summer of 2021. The company has secured significant funding, including a $3.1 million seed round in June 2022 and a $21 million Series A round in January 2025, co-led by PayPal Ventures and Portage Ventures. This funding is aimed at fueling expansion across the US and Europe and enhancing its platform capabilities.

The core of Formance's offering is its programmable Ledger, an open-source transactional database that serves as a single source of financial truth for businesses. This system provides detailed visibility into every transaction, enabling real-time balance tracking, audibility, and streamlined reconciliation. The platform is built to be vendor-agnostic, allowing clients to connect with their preferred financial service providers. The full Formance Platform includes four main components that integrate with each other: Ledger, Connectivity, Flows, and Reconciliation. This modular suite helps clients manage everything from payment processing and white-label wallets to orchestrating end-to-end financial workflows. The business model offers various deployment options, including a fully managed Formance Cloud, a hybrid model, and a completely self-hosted solution, providing clients with flexibility based on their technical and regulatory needs. Formance serves global clients such as Doctolib, Liberis, and Booksy, enabling them to ship new financial products faster and with greater control over their infrastructure.
