I first met Jud Bowman when he was like 18 and started a mobile search engine called Pinpoint. They merged with another company and became Motricity which was one of the biggest exits in the Triangle. Jud knows a ton about the mobile world and his new company, Sift uses advanced big data analysis to understand and target cell phone users. Sift has built a profile of 1.2b app installation footprints and uses that to better target app downloads. For example, if a user has 4 travel apps, then they are more likely to download another travel app.
