We’re here because we don’t believe there’s a level playing field that gives small businesses with a fighting chance against the giants of the high street.We’re here because we see banks and legacy service providers making things harder for them. We don’t think the best technology or the best service should be reserved for those with the biggest headquarters.We’re here to fight for a future where small, local businesses can thrive, and to commit the same dedication they offer all of us.
