Increase has announced the launch of Increase Bank, combining a modern bank core with regulated banking services to help teams build financial products with greater speed, precision, and control. Founded in 2020, Increase’s banking infrastructure and APIs enable companies such as Gusto, Ramp, and Stripe to move, store, and lend hundreds of billions of dollars. With the addition of Increase Bank, an FDIC-member institution, fintech companies now have access to a bank designed for their needs.

Darragh Buckley, founder of Increase, said: “This is a bank built by a team of product-obsessed operators for ambitious companies that are just as obsessed with building the best possible products for their customers.” He added: “It is programmable at scale and designed for reliability, speed, and flexibility.”

The idea for Increase grew out of Buckley’s experience building Stripe from its earliest days, where he saw the need for banking infrastructure built with the same engineering depth as the fintech companies that depend on it. Since then, the fintech industry has become one of the fastest-growing sectors in technology, generating over $650 billion in revenue in 2025 and growing at about 21 percent year over year. That scale helps explain why infrastructure choices matter for fintech teams, which often need banking, payments, and ledger systems to work together without slowing product development.

Increase now includes Increase Bank and a modern banking core with direct connections to the Federal Reserve, The Clearing House, and Visa. Increase’s technology maintains the system of record for account balances and transactions and reconciles to the Federal Reserve in real time. The company says this gives fintechs full control over accounts and allows them to operate with their bank at the same speed and scale as their business.

Diede van Lamoen, former Head of International at Stripe and an advisor, said: “A fintech company’s ability to scale often comes down to whether they have a banking partner that can move at their pace, build solutions to the edge cases they are solving, and give them direct access to payment rails.” He added: “Increase was built by people who have first-hand experience with these challenges and a drive to support users from the first payment to their billionth.”

Increase’s technology is trusted by some of the largest fintechs and software platforms in the United States, providing flexible, transparent, and reliable primitives for money movement, storage, and card issuance.

At Ramp, Co-CEO Karim Atiyeh said: “At Ramp, we are building AI for finance, and we must move fast to save our customers’ most valuable resources – time and money. Increase provides the banking infrastructure we need to do just that. From the ability to open accounts synchronously, fully featured for every payment rail, from day one to the pace they ship new features, Increase just gets it.”
