PALO ALTO — Lithium Technologies has snatched up the social media scoring startup Klout for about $200 million, the San Francisco-based companies announced on Thursday. Lithium turned to Wilson Sonsini Goodrich & Rosati for counsel while Klout tapped Goodwin Procter.

Lithium, founded in 2011, helps brands like AT&T, Best Buy, Sephora and Skype with customer service management by giving them data on social technology platforms. Rob Tarkoff, president and CEO, said with 6-year-old Klout under its wings, Lithium will “deliver on its vision of building a trusted online connection between consumers and the brands they care about.”
