Bump Technologies (acquired by Google

Bump Technologies is one of the most valuable companies ever funded by Y Combinator, having raised $20 million dollars since 2009. This acquisition is Google's eighth known acquisition of a YC-funded company. Through this acquisition, Google acquires Bump's 23-person team, the Flock group photo-sharing app, and several mobile technology patents. Liz Gannes at AllThingsD reports the acquisition "was worth at least $30 million, and perhaps as much as $60 million."
