41. Floxx Media Group

Founder: Rich Martell                
Founded: January 2011

Floxx started as a joke, founder Rich Martell cheerfully admits. Its first product, the somewhat controversial FitFinder, started life as little more than a (technically impressive) university prank. But developing it, as well as further products Spottd, MapChat and Appdaq, involved Martell working with agencies to develop mobile apps, a process he found so frustrating that he decided to do it himself – better.

Today the company specialises in creating apps and websites, and has built up solid revenue streams, both from its agency business, doing work for clients for hire, as well as income from app sales (downloads, in-app purchases and subscriptions). Having raised around £300,000 in investment so far, the next 12 months are focused on growth, with plans to build the team, currently of eight, as well as the client base.
