I work with the UK Government to help the cream of UK tech companies get Series A funding in the Afterburner Programme. This has raised $50 million since April 2014, from investors in the UK and Europe, as well as The Valley and Japan.

I also do angel investing via Ballpark Ventures, am Chairman of LoopMe, Constant Commerce and TapDaq, I'm an advisor to On Device Research and Qriously, a Director of Palringo, AdLudio, Depop, and AppearHere.

Before that, I was the first employee of AdMob in 2006, which exited to Google four years later for $750m.

I'm also the ex-Global Chairman of the Mobile Marketing Association, an occasional blogger at MobHappy and do a fair amount of speaking about mobile, retail and "the future".
