PostUp Buys UberTwitter, Becomes UberMedia

Pasadena-based PostUp, the Internet advertising firm spawned out of Idealab, said Friday afternoon that it has acquired UberTwitter, developer of a Twitter client that runs on the BlackBerry Platform. Financial terms of the deal were not disclosed. As part of the acquisition, the firm said it has changed its named to Ubermedia. The name change marks the second for PostUp (formerly known as TweetUp) in less than six months; the firm had changed its name in August to TweetUp. UberMedia is headed by Idealab's Bill Gross; Jon Kraft, who was most recently at BigStage entertainment, was a co-founder of Pandora, and has been very active locally with the Technology Council of Southern California, is now Chief Operating Officer of the firm. The acquisition of UberTwitter is third Twitter client acquisition for the company; it previously acquired Twidroid and Echofon.
