US-based celebrity media management platform WhoSay secured an undisclosed amount of funding from venture capital firm Greylock Partners on Monday. Online retailer Amazon and venture capital firm High Peak Ventures are among WhoSay’s existing investors. WhoSay closed its series A round, in June 2010, having raised $2.4m. WhoSay, which was co-founded by entertainment and sports agency CAA, provides public figures with a platform to manage their social networking while giving fans an officially sanctioned base to access that content. David Sze, partner at Greylock Partners, said: "WhoSay has found a way to make this engagement process easier for celebrities which, in turn, gives fans more of the unique and authentic content from major influencers that has rarely been available before. The quality of the celebrities already active on WhoSay leads to word of mouth growth to other major celebrities looking to solve the same challenges."
