Griffin processes GBP £3 billion as revenue surges

UK bank Griffin has reported a fivefold increase in revenue over just over a year of full operations, alongside roughly £3 billion in processed payment value and more than 50 platform customers.

The London-based bank said it now serves hundreds of thousands of end users through its platform customers. Griffin listed Yonder and Prosper among customers that are live on its infrastructure. It also named Uber, Marqeta, Access Group, Aspora and Sidekick as integrations that are live or in testing and integration.

Griffin began full operations in March 2024 with five companies in a Foundations programme, according to the company. It said the programme tested its systems ahead of a wider launch in September 2024.

David Jarvis, Chief Executive Officer and Co-Founder at Griffin, said the past year marked a step change in how the bank works with technology-led businesses.

"2025 was the year we became the partner bank of choice for fast-moving technology companies in the UK," said David Jarvis, CEO and co-founder of Griffin. "We've proven you can build a bank that moves as fast as the fintechs it serves without compromising on compliance or resilience. The companies integrating with us aren't just taking a bet on the future-they're building on proven infrastructure that scales."

Customer footprint

Griffin described its customer base as platform businesses that build on its banking infrastructure and offer financial products and services to their own customers. It said it has more than 50 such platform customers.

The company said it has processed about £3 billion in payment value as of December 2025. It said revenue grew by a factor of 5 in just over a year of full operations.

Griffin positioned its offering as infrastructure for firms looking to add financial products to their customer experiences. The company said it supports savings accounts, current accounts, operational accounts, payments and compliance products.

It said customers access these services through an application programming interface. Griffin also referred to a developer sandbox.

Integrations

The company highlighted a set of larger brands and fintech infrastructure providers among its integrations. It named Uber, Marqeta and Access Group, alongside Aspora and Sidekick.

Griffin did not provide further details on which specific products or services each partner uses. It said more information on products and integrations for Uber, Marqeta, Access Group, Aspora and Sidekick will follow in the new year.

Sidekick Money's leadership described its experience working with Griffin and the time taken to go live.

"Griffin represents the infrastructure layer that will enable the next generation of financial services in any industry" said Matt Ford, Co-founder & CEO at Sidekick Money. They've built banking in a way that it can scale for both existing companies, new entrants and new industries. "We went from signing our contract to going live in 8 weeks, which speaks to both the quality of their infrastructure and expertise of the team," said Ford.

Market backdrop

Griffin's update lands as embedded finance continues to expand across Europe, with more businesses exploring financial products delivered within non-bank services.

The company said its regulated status as a UK bank forms a core part of its proposition. Griffin said it is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the Prudential Regulation Authority.

Griffin said it has provided banking infrastructure across multiple sectors. It listed wealth management, payments, lending, remittance, insurance, proptech, and digital banking.

Next steps

Griffin said it plans to scale its payments infrastructure in 2026. It also said it plans to introduce a card programme and launch its stablecoin offering.
