SimpleGeo is a location-based service that provides the infrastructure and tools for implementing location elements into applications. Urban Airship, a company that helps companies build apps with push notifications and monitor analytics, has acquired SimpleGeo.

After a hiatus from working as a tech executive, former Digg CEO Jay Adelson has joined SimpleGeo as the new CEO. Founding CEO Matt Galligan will become the Chief Strategy Officer of the company. SimpleGeo raised about $10 million in venture capital and it allows companies to add location features to geo-location applications.
