Griffin - Building the Yes Bank with APIs for Fintechs and SaaS Companies
Griffin is revolutionizing embedded finance with a UK-licensed banking-as-a-service platform, enabling fintechs to launch accounts, payments, and more without relying on multiple vendors, ensuring robust compliance and operational efficiency.
Embedded finance dies when the bank says no.
Griffin is building the bank that says yes, with APIs.
It is a UK licensed bank and banking-as-a-service platform, so fintechs and vertical SaaS companies can launch accounts, safeguarding, payments rails, cards, and an integrated ledger without stitching together a sponsor bank, a core, and three compliance vendors.
The business model is classic infrastructure: charge for accounts and payments volume, add platform fees for ledger and compliance automation, and keep margins healthier by owning more of the stack and operating under its own licence.
Founders David Jarvis and Allen Rohner are engineers, not ex-bank sales guys. Jarvis worked at Standard Treasury (acquired by Silicon Valley Bank) and later at Airbnb, and Rohner co-founded CircleCI, which shows in Griffin’s developer-first product posture.
In March 2024, Griffin exited mobilisation and became a fully operational bank, and it extended its Series A with £19m (about $24m) led by MassMutual Ventures, NordicNinja, and Breega, with Notion Capital and EQT Ventures participating, bringing total funding to around $52m.
This matters now because BaaS has been punished for thin compliance and sponsor-bank fragility. Griffin is betting that “boring” regulatory capital plus modern infra is the real moat, and FinBox Solutions likes the bet.

If you were building embedded finance in the UK today, would you pay more for a licensed bank like Griffin, or take cheaper sponsor-bank rails and accept the risk?
