About Flagstone

Flagstone runs an online cash deposit platform where savers can open and manage high-interest savings accounts and Cash ISAs from more than 65 UK banks and building societies. Customers use one application and one password, and cash in the holding account is described as FSCS-eligible. The company states that it is not a bank and does not provide financial advice.

Customers are UK savers aged 18+ with a UK bank account and a minimum deposit of £10,000, and the company also works with wealth management companies and financial advisers. It earns a small share of the interest that partner banks pay on accounts opened through the platform, and says it charges no admin, management or platform fees.

The registered company is Flagstone Group Ltd., with its head office at Clareville House, Oxendon Street, London. The About page gives a figure of £149m raised from investors and 350+ staff. The careers page lists four open London roles: Staff Digital Marketing Manager, Data Analytics Senior Manager, Relationship Team Leader - Strategic Networks, and Senior Application Security Engineer. The founding year is not stated on the website.

Product: Online platform for opening and managing multiple high-interest savings accounts and Cash ISAs from 65+ UK banks under one login.
