Increase

Increase is a banking infrastructure platform purpose-built for technology companies, offering a full-stack suite of enterprise-grade APIs that provide direct access to U.S. payment rails including ACH, wires, real-time payments (RTP), FedNow, physical checks, and card issuing via Visa. Founded in 2020 by Darragh Buckley — Stripe's first employee — the company built its own bank core rather than relying on legacy systems, enabling direct connections to the Federal Reserve, The Clearing House, and Visa. Unlike competitors that abstract away underlying network complexity, Increase passes raw settlement data and trace identifiers through to customers, enabling full reconciliation visibility. Customers including Ramp, Gusto, Check, Pipe, AtoB, and Coast use Increase to build and scale financial products such as payroll disbursement, bill pay, embedded lending, fund administration, and spend management. The platform supports programmatic account opening, flexible FBO and customer-titled account structures, real-time card authorizations, and approval workflows. Increase operates as a non-bank, with FDIC-insured banking services provided through partner banks Grasshopper Bank, First Internet Bank of Indiana, Twin City Bank, and Core Bank. The company is self-funded, never having raised external venture capital, and reached profitability in 2025 while processing hundreds of billions of dollars in payments annually.
