And the company has made several billion in funding available to over 100,000 businesses since launching, positioning itself as a leading European fintech.

Company values

- Smart: At iwoca being smart isn't about what you know, it's about how you think. Smart thinking means looking at each problem by asking ‘why’ first, then figuring out ‘how’
- Humble: We know all ideas are flawed, all code has bugs, and everyone makes mistakes - it’s how we learn. For us, being humble means you question yourself first, rather than your team
- Growth Mindset: We think there's always a better way to solve a problem. So we never let ourselves get comfortable with being good enough
