Flagstone

Flagstone is a high‑growth UK-based fintech specializing in cash‑deposit aggregation. Founded in 2013 (or 2015, as some records note) by Simon Merchant and Andrew Thatcher, the company operates a platform enabling retail, SME, charity, and wealth‑management clients to access and manage hundreds of savings accounts from 60–66 UK banks via API, white‑label, or direct channels ([fintech-intel.com](https://fintech-intel.com/flagstone-raises-12-million-in-funding/?utm_source=openai)). Flagstone is headquartered in London, at New Zealand House ([leadiq.com](https://leadiq.com/c/flagstone/5a1d7ebc2400002400597afb/employee-directory?utm_source=openai)). The company has scaled impressively: as of 2024, it administers between £13 billion and £16 billion in assets under administration (AUA) for over 600,000–725,000 customers, and generated £55 million in annual revenue, up ~46% year over year. It has been consistently profitable since late 2022 ([linkedin.com](https://www.linkedin.com/posts/seb-johnson_tech-flagstone-founders-activity-7300145017745018882-YLKY?utm_source=openai)). On the funding front, Flagstone raised approximately £108 million (~$138 million) in March 2024 via a Series C from Estancia Capital Partners. That brought total investor backing to about £150 million, including participation from OMERS Ventures, Kindred Capital, and MoneySuperMarket Group ([estanciapartners.com](https://estanciapartners.com/flagston-receives-108-million-investment-from-estancia-capital-partners/?utm_source=openai)). Operating in fintech/cash‑management, Flagstone stands out for its rapid growth—ranked among the UK's fastest‑growing tech firms, with ~95% three‑year sales growth—and strong brand partnerships (Revolut, St James’s Place, Saga) ([thetimes.co.uk](https://www.thetimes.co.uk/article/flagstone-s0jkkh2hr?utm_source=openai)). With about 300–350 employees globally and plans to exceed 400 by end‑2025, the workforce seems to consist of talent drawn from fintech, banking, and wealth management sectors ([thetimes.co.uk](https://www.thetimes.co.uk/article/cash-managed-by-flagstone-leaps-by-a-half-enterprise-network-gwjwpv599?utm_source=openai)). Overall, Flagstone offers a compelling profile for ambitious professionals: a profitable, well‑backed, fast‑scaling fintech with significant market traction, institutional credibility, and strong operational momentum.
