Founder story
Founded in 2015 by brothers Andrew, Jacob, and Peter Sever (with twin brothers Peter and Jacob) and Vyacheslav Zholudev in London. The founders, friends with fintech developers, realized that KYC was a massive bottleneck for innovation. They leveraged their backgrounds in computer graphics and image processing to automate the process, scaling from a 'basement startup' to a global unicorn.
