"One hundred million people with Klout Scores means that there are 100 million voices effectively leveraging the social web to share their opinions, hopes and dreams and shaping the decisions of the billions of people now listening to them," Klout co-founder and CEO Joe Fernandez says of the milestone.
To be clear, Klout has yet to sign up 100 million service users. Instead the startup measures the influence of its users and their social network friends by association, as pulled in via social graphs on Twitter, Facebook and recently added networks such as Instagram, Foursquare and LinkedIn.
Still, now that Klout is tracking the scores of more than 100 million people on the web, the startup can solidify its place as the de facto measurement tool for influence online and appeal to even more brands and marketers looking to locate and leverage their most socially persuasive fans and customers.
