The financing round was backed by Kindred Capital, Moneysupermarket Group, and VentureFounders.
Flagstone operates a cash savings platform that connects individual, business, and charity clients with a wide range of bank accounts. The firm administers over £11bn in assets.
London-based fintech platform Flagstone has secured £11m in growth capital to scale operations. The financing round drew participation from Kindred Capital, Moneysupermarket Group, and VentureFounders, alongside private investors.
Founded in 2013, the company has channeled more than £3bn in deposits through its system, serving individuals, charities, and corporate clients by aggregating numerous bank accounts into a single interface. The new capital will support the company as it looks to extend its market reach and deepen its banking partnerships.
From the founder
"With £11m of growth capital we are now well‐positioned to expand our business and provide more clients with a simple way to maximise the interest income on their cash and at the same time become an increasingly valuable funding partner to our banks."

Simon Merchant
Co-Founder and CEO at Flagstone
