WhoSay Inc., the social and media management platform for people in the public eye, has raised a $12 million Series C round led by Comcast Ventures. Existing investors Greylock Partners, Amazon and High Peaks Ventures also participated, as did Tencent.

The company, which was co-founded by Creative Artists Agency (CAA), said it will use the funding to continue its U.S. and international expansion and to further develop its proprietary product.

WhoSay, which can only be joined by invitation, has more than a thousand high-profile members who collectively have more than a billion social media networks connections. The platform enables members to establish and maintain a direct connection with their fans on Facebook, Twitter, Tumblr, YouTube and Tencent, as well as media partners like Viacom/MTV Networks, the Associated Press and Yahoo.
