It all started in spring 2019, in a secret office on the seventh floor of JP Morgan’s London headquarters in Canary Wharf. Tucked behind the bustling staff canteen, at the end of a corridor that snaked past the office gym and in-house doctor, future Chase UK chief executive Kuba Fast was digesting the task ahead of him: helping build a new digital bank – from scratch – for the Wall Street giant.

He had been selected to join the project months earlier by fellow McKinsey alumnus Sanoke Viswanathan, who had been travelling the globe to learn from other successful digital lenders, including Fast’s former employer, Poland’s mBank. JP Morgan gave little detail about its venture, which was then known by its codename, Project Dynamo. But Fast dived headfirst into the blank-slate project. “I agreed to join before knowing where I would live,” Fast says.
