UK Bank Griffin Raises $20 Million to Build Stablecoin Payment Services

UK banking platform Griffin has raised $20 million in a Series B round announced November 12, at a valuation above $100 million, to build stablecoin payment services on top of its regulated banking infrastructure. Octagon Partners led the round, with participation from Notion Capital, A+ Ventures, Nordic Ninja and Breega.

The raise is not a token venture spun from nothing. Griffin already holds a UK banking licence and operates a platform serving more than 80 companies and over 300,000 retail and business customers. It processes nearly 10 million payments per year — roughly 27,000 each day, or one payment every three seconds around the clock.

What will the money actually fund?

The capital is earmarked for four product lines, according to the announcement:

• Branded debit cards for consumers and companies, with credit cards to follow later
• Stablecoin reserve services, meaning custody of the assets that back tokens pegged to fiat currency
• On-chain cross-border payments
• Continued buildout of the underlying banking platform

CEO and co-founder David Jarvis framed the expansion as a logical extension rather than a pivot. "Cards and stablecoins are the natural next layer for our infrastructure," Jarvis said. That claim deserves scrutiny: stablecoin reserve management is a custody and treasury function, not a payments rail, and conflating the two is common in marketing language across the sector.

Stablecoins are crypto assets designed to maintain a stable value, typically pegged to a fiat currency such as the dollar. Offering reserve services from inside a licensed UK bank would place that function under Prudential Regulation Authority and Financial Conduct Authority oversight — a structural distinction from stablecoin issuers operating outside the regulated perimeter. Griffin did not say which stablecoins it would support, nor which chains the cross-border payment product would settle on.

What do the growth figures show?

Griffin reported that recurring revenue grew 3.2x year over year in the financial year ended September 2026. That means annual recurring revenue more than tripled in twelve months. The company itself concedes a caveat: the figure rests on unaudited accounts and may change after the statutory audit.

A 3.2x multiple on an undisclosed base is an impressive ratio but an uninformative one. Without the absolute revenue number, the growth rate cannot be sized against competitors such as Railsr, ClearBank or Embedded, all of which occupy adjacent ground in UK banking-as-a-service. Griffin did not disclose the base figure.

The company also omitted the detail investors and rivals will ask first: launch dates. No timeline was provided for the debit cards, the credit cards, the reserve services or the cross-border payments product. A fundraising announcement without a delivery schedule is a promise of intent, not a product roadmap.

Why does a licensed bank moving into stablecoins matter?

If Griffin delivers regulated stablecoin reserves and on-chain settlement, it would narrow the gap between UK prudential banking and the offshore stablecoin market that has grown largely outside it. The Financial Conduct Authority is expected to finalize its stablecoin regime following the Financial Services and Markets Act 2023's designation of crypto activities; firms with existing licences are positioned to move faster than new entrants once those rules take effect.

Whether the products arrive before that regulatory window closes is the question the $20 million must now answer.
