Griffin raises $20M Series B led by Octagon Partners at a valuation above $100M

Griffin has raised a $20 million Series B led by Octagon Partners, at a valuation above $100 million. Notion Capital, A+ Ventures, Nordic Ninja, Breega and other existing investors took part.

Griffin is a UK bank for fintechs and platforms, led by CEO and co-founder David Jarvis. Two years after launching with a full banking licence, more than 80 companies build on it, including Uber, Countingup, Anna Money, Yonder and Prosper. The platform serves over 300,000 underlying retail and business customers and processes nearly 10 million payments a year. Recurring revenue grew 3.2x in the year to September 2026, on unaudited accounts.

The money funds two additions: card issuing, starting with branded debit cards and then credit cards, and stablecoin services, covering reserves and on-chain cross-border payments. Griffin says the financing also carries it through to profitability.
