“Can a UK digital bank built on specialist SMB lending become the full-service transaction banking platform for growth-oriented lower mid-market businesses in the UK and US?”
Founded in September 2015 as a UK digital bank focused on lending to growth-oriented SMEs and offering consumer savings products.
