Why work with Flagstone?
Market-leading bank panel
From high-street leaders like HSBC to established challengers like Allica, we work with more banks than any other cash deposit platform. Which means unparalleled choice for our clients.


Trusted by UK institutions
We partner with some of the UK’s most established finance brands. St. James’s Place, Saga, Money Supermarket and more. We know that talk is cheap – but trust is earned.
Flexible integrations
However you work, we’ll work alongside you. Whether it’s an API integration with our platform, a white-labelled version of our platform, or a more straightforward ‘referrer’ relationship.


Dedicated account management
Our partnerships are personal. So you’ll receive a dedicated account manager to ensure a smooth journey with Flagstone, through integration and beyond.
