We’re here because we believe in small businesses. We believe they deserve better than waiting weeks for a loan. And we believe it’s our job to help them grow.

We started in 2012 with these principles, and we hold true to them today – now that we’re one of the fastest-growing fintechs in Europe. In the time between, we’ve built the best tech platform in lending, won several awards and opened up £3.5 billion in loans to over 90,000 businesses.

So what’s next? Our mission now is to help one million businesses who need us. To do this, we’ll need new products and partnerships. But most of all, we’ll need smart, hands-on people to join us on the journey and get us to our goal.
