About Apron Apron is focused on helping more small and medium businesses succeed. The biggest threat to small business is cash flow, often stemming from a gap between the demand payments put on owners and the aptitude to make the payments effectively. We are closing the gap by digitising and simplifying the payments process: capturing invoices, issuing expense cards, paying and getting paid, all in one place. We have grown fast over the past few years, expanding our team to circa 100 individuals across the UK, Germany, Spain and more. We are backed by Index Ventures, Bessemer Venture Partners, Zinal Grow and Tony Fadell and we’ve raised $50m. About our engineering culture Engineers at Apron are at the heart of what we do. Here's what that means: We build with the customer in mind. We use top-tier technology to build a product that genuinely makes their lives easier. We own our work. We plan the approach, break it down, and bring it to life! We embrace the complexity of finance. Working with money means navigating intricate business logic and thinking through every possible corner case. It’s a rewarding challenge where precision and attention to detail are crucial for building a trustworthy product. We write code we're proud of. We work fast, but we build for the long term. Our code needs to be speedy, secure, and ready to grow with us. We integrate AI tools. We use what's best out there to build a product that genuinely makes lives easier.
