Lean Supported Banks: 5+ Institutions (2026)

Lean is a banking API aggregator: one integration model so apps can reach many institutions with user consent. We list about 5 institutions in this directory; your app’s real coverage can still differ by product and market. For a simple mental model, Lean is like a power strip for financial data: many banks share one interface, and your product plugs in once.
