According to Fortune, Klout has been acquired by Lithium Technologies, a social customer service company.
Today, Fortune is confirming that the social score startup has been acquired by Lithium Technologies for nearly $200 million. Re/code estimated the deal to be least $100 million. Klout and Lithium Technologies declined to comment on the report.
Fortune adds that the deal will be announced Thursday morning in a joint press conference. Sources tell Fortune that the deal is a mix of cash and private stock.
If the acquisition is true, it will be an unusual buy where in a startup is buying another startup. Founded in 2008, Klout was born out of the need to measure social influence in the web. Many didn't get the idea, but Klout managed to raise more than $40 million in funding from investors including Kleiner Perkins, Venrock and Institutional Venture Partners.
Lithium Technologies, on the other hand, offers social customer experience management software for businesses. Last year, the company raised over $50 million in pre-IPO mezzanine financing. Lithium Technologies is expected to file for an IPO later this year.
