This London studio has released 11 racing games, played on mobile phones by more than 250 million people worldwide. Online interaction increased during lockdown via a broadened calendar of live events for titles including Rebel Racing and Top Drives, and on forums that have at least 200,000 members. Hutch also has a licensing deal with Formula One for F1 Manager, a game in which players create their own F1 teams and compete against rivals. Chief executive Shaun Rutland, 45, launched the company in 2011 with four former colleagues from PlayStation, and has since expanded operations to Canada and Dundee. Shareholders include Index Ventures and Backed VC, which invested $5.5m in 2017. Sales hit £15.1m last year.
