About

Swan is Europe’s embedded banking specialist. We empower software companies to embed banking features like accounts, cards, and payments directly into their products, under their own brand.Swan processes over €1.5 billion in monthly transactions for more than 150 companies—like Pennylane, Indy, Agicap, Libeo, and Lucca. Founded in 2019, the company has received growth capital from leading investors such as Lakestar, Accel, Creandum, Bpifrance and Eight Roads. Swan is a principal member of Mastercard and a licensed financial institution, regulated by the French banking authority (ACPR).

Our mission

Banking belongs in business software

Many software companies already serve small businesses incredibly well: helping them send invoices, run payroll, manage inventory, and more. They’re on a mission to become the central hub for managing every aspect of business life.

But when it comes to financial workflows, there’s still a gap. Too many critical tasks like managing cash flow, tracking payments, or reconciling accounts happen outside the software, across spreadsheets, email threads, banking portals.

It’s a missed opportunity. Business software shouldn’t just record financial activity — it should run it.
