Customer service software firm Lithium Technologies has reportedly snapped up social score start-up Klout in a deal valued at around $200m.

Fortune noted that the deal comprises a mix of cash and Lithium private stock.

Another report from re/code revealed that Lithium, which itself is a start-up gearing up to go public this year, has raised $50m in venture funding, while Klout raised $40m.

Established in 2008 by CEO Joe Fernandez and Binh Tran, the start-up works as a means to calculate measure influence on the increasing social Web.

Signed users would receive a ‘Klout Score’, which is a numerical value between 1 and 100, and the score determines the social pull of the user.

Furthermore, the start-up reportedly modified its scoring algorithm upon claims that of rating tech blogger Robert Scoble’s social media influence higher than that of US President Barack Obama.
