WhoSay

WHOSAY is an influence marketing agency owned by Viacom that was founded in Los Angeles in 2010. It was notable for allowing its users to retain ownership rights over the content that they post to their accounts  and for enabling users to post content to other social media sites.

History
WHOSAY was founded in March 2010, by Steve Ellis and the Los Angeles-based talent agency Creative Artists Agency (CAA). The company's main headquarters are in The New York Times Building in Manhattan. The company was founded to protect celebrities' intellectual property and enable the celebrities themselves to profit themselves from their own online content.

The company started slowly, until CAA client Tom Hanks signed onto WHOSAY three months after the service's launch. The company continued to maintain a low profile for the first three years of operation, during which it accumulated a client list of 1,500 actors, musicians and artists. Clients are accepted by the service on an invitation-only basis, although they are not restricted to Creative Artists clients.

In September 2013 WHOSAY introduced a mobile application for consumers. WHOSAY does not allow consumers to create accounts, nor does it include search features, making it difficult to access a celebrity's account unless a user is directed there from one of their other social pages.
