Ed spent the first twelve months of the mobile app gold rush building iPhone apps, both on contract and independently. Two of these independent apps reached the number one spot in the iTunes App Store - TV Plus (the first app to set Sky+ to record from iPhone; 6 months before BSkyB released a similar app) and iPhone MMS (the only way to send and receive MMS on UK iPhones before Apple's 3.0 firmware). Before entering the mobile space, Ed worked at Transitive; first as a software engineer, then technical lead and finally pre-sales engineer. Transitive was the leader in cross-platform virtualisation, creating products such as "Rosetta" for Apple, before it was acquired by IBM in December 2008.
