Hello, we’re Starling. Banking was broken – so we decided to fix it. The vision? Fast technology, fair service and honest values. All at the tap of a phone, all the time. We built Britain’s first digital bank. One hard-won banking licence later, we set about giving people a new way to spend, save and manage their money (and take better care of the planet, too). We’re changing banking for good. Back then, we were obsessed with unravelling the knotty world of finance and solving people’s problems rather than selling them stuff. We still are. Since then, we’ve grown. A lot. Over four million accounts (and four account types!). A team of thousands. Headquartered in London with offices in Cardiff, Dublin, Manchester and Southampton. Seven years voted Which? Recommended Provider and Britain's Best Banking Brand. Still zero branches. Our culture is open, inclusive and focused on solving real customer problems, with an emphasis on doing the right thing, even when it’s not always the easy...
