Why Would Anyone Build a Bank?

David Jarvis - Founder/CEO, Griffin

January 15, 2026

Starting a bank seems like one of the hardest things you could possibly do. David Jarvis, CEO of Griffin, did exactly that and walks me through the WHY and HOW of building a bank from scratch.


Getting a banking license is no joke! I thought I understood this from my Monzo days, but turns out I'd only scratched the surface.

In this episode, we get into:

  • How the licensing process actually works - from the first phone call to the Bank of England through 4.5 years of iterative feedback
  • Why every bank has a £1M monthly burn rate
  • The reality of raising £50M before you have a single customer or £ of revenue
  • What actually happens when you send a payment (there's probably another bank involved)
  • Why Revolut, with 70M customers, is still fighting for a banking license

David also shared about the less glamorous bits of startup founder life, but you’ll have to listen to find out!
