Our take
UK SMEs are the backbone of a complex economy that is constantly changing, so the need for fast and responsive access to finance is becoming more and more important to ensure their success and growth. iwoca allows SMEs access to business loans in less than a minute, with its API and business marketplace partnerships.
With offerings like iwoca's, gone are the days where waiting up to eight weeks for a loan decision was viable. Its simplified business loans of £1,000 - £500,000 come with no fees attached, and applying online takes no more than five minutes. The ready availability of iwoca loans gives business owners a level of certainty, so that they can make instant decisions to help their business grow.
iwoca has made a number of partnerships with other players in the business finance space, including an impressive industry-first invoice checkout integration with QuickBooks. Funding raised by the company, which is now operating at net profitability, will enable it to meet a recent surge in demand for corporate loans and offer more to larger SMB businesses. And the company has made several billion in funding available to over 100,000 businesses since launching, positioning itself as a leading European fintech.

- 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
