The story

The company was founded in 2008 by Victor Malachard, Paul Childs and Wesley Biggs, and the service launched in July 2009. It secured funding in 2010 and 2011, and in April 2011 was the only mobile advertising company to make the final Telegraph Tech Start Up 100 list. In December 2011, the company won 'Angel or VC-Backed Business of the Year' at the Startups Awards.
