The US could be one of the most lucrative markets for digital banks, but few new entrants have launched there. Why? How ripe is the opportunity, really?

Monzo, N26 and Revolut have all stated intentions to launch in the US, though none have yet navigated the regulatory requirements.

Colin Walsh is the CEO and co-founder of Varo Money, which is on track to become the first mobile-centric national bank in U.S. history.

Prior to founding Varo, Colin spent 25 years in consumer banking at American Express, Lloyds Banking Group and Wells Fargo.
