The problem

Retail finance is ruled by old customs and regulation using rigid, elderly technology and policy that then hardwires those problems and makes it hard, if not impossible to offer clients good service.

Lending decisions are often taken based on traditional salary data, ignoring newer forms of earning and assets which may be less regular, but often more valuable. The many productive and creditworthy entrepreneurs and expats, and even wealthy early retirees can be left out in the cold.

Most people hate or at best feel indifferent about their bank. Branch networks have been cut and service automated poorly. New app-based banks have provided much better tech but it’s still hard to speak to a human being and most cater only to the mainstream customer.

How we fix it


What makes us different?

  • Clear, innovative thinking
  • Knowledge of the new economy
  • Finance that crosses borders
  • Deep tech and data savvy
  • Commitment to your best interests
  • Warm and professional service
  • No unnecessary forms or delay

Our vision

We want to make finance work for the entrepreneurial, international and young

Too much of the financial world only works for those for the wealthy of the old economy; we want to bring the benefits of liquidity, long-term investing and prudent borrowing to those working to build a newer world. Doing that will help us build long-term relationships of mutual trust for the future.
