Overview

WhoSay was an American social media service and branding platform created for celebrities, public figures, and, later, brands working with celebrity talent. Founded in Los Angeles in March 2010 by former Getty Images executive Steve Ellis together with Creative Artists Agency (CAA), the company addressed a specific problem in the early social-media economy: celebrities were publishing photographs, videos, and other material on third-party networks while often losing control over the associated rights, audience data, and commercial opportunities. WhoSay presented itself as a system through which high-profile users could manage their own digital presence, retain ownership claims over material they posted, and distribute that material across multiple social networks from one place. The service was unusual in that it focused on invited celebrity accounts rather than attempting to build an open social network for the general public. Its tools enabled approved users to publish to destinations including Twitter, Facebook, Instagram, Tumblr, and, in some cases, Chinese social platforms. Content carried copyright and branding information intended to reinforce the celebrity’s ownership and identity. WhoSay also operated an editorial component that positioned the service as a kind of celebrity-focused digital magazine, combining first-party posts with entertainment coverage and updates. WhoSay received financing from CAA, Amazon.com, Comcast, Greylock Partners, High Peak Ventures, and other investors. Amazon and CAA were reported to hold minority interests. The service gained an important early client when Tom Hanks joined several months after launch. During its first three years it maintained a relatively low public profile while building a roster reported to include approximately 1,500 actors, musicians, artists, and other public figures. Clients named in public descriptions of the platform included Kelly Clarkson, Julia Louis-Dreyfus, Paula Patton, Kevin Spacey, Jim Carrey, John Cusack, Bill Maher, Johnny Knoxville, Chelsea Handler, Eva Longoria, Spike Lee, Enrique Iglesias, and Katie Couric. WhoSay’s commercial model was designed to minimize direct costs for participating talent. Clients were not charged for the service and could receive a share of advertising revenue. The platform also offered access to registration-related audience data, including email contacts, allowing celebrities to maintain a more direct relationship with fans instead of relying exclusively on the algorithms and policies of large social networks. This emphasis on ownership, distribution, and direct communication distinguished WhoSay from ordinary social scheduling tools. The company expanded beyond its original celebrity-user focus during the middle of the decade. A consumer mobile application was introduced in September 2013, and the website was reported to attract 12 million monthly visitors by October of that year. In July 2014, Rob Gregory joined as chief revenue officer after serving as president of Newsweek’s The Daily Beast, with responsibility for advertising, premium commercial formats, and brand partnerships. By February 2015, WhoSay was reported to have 4.8 million unique users and had begun offering accounts and services to companies that employed celebrities in branded-content programs. The platform’s advertising business connected entertainment talent with marketers including Lexus, Chevrolet, KFC, JCPenney, Dunkin’ Donuts, and Crest. These programs used celebrity-created material and coordinated distribution across social channels, making WhoSay both a publishing tool and an influencer-marketing intermediary. Its Lexus work with Rosario Dawson involved short videos tied to the 87th Academy Awards period and the promotion of Studio One Eighty Nine, a clothing initiative connected with Dawson’s foundation. Its Chevrolet partnership used well-known personalities in a humorous classroom-substitute-teacher campaign. WhoSay deliberately did not allow ordinary consumers to create accounts, and its service lacked a conventional search function. This limited the platform’s usefulness as a standalone social destination but reflected the company’s strategy of serving high-profile creators rather than competing directly for mass-market social-network users. In January 2018, WhoSay’s website and business were acquired by Viacom. Publicly available reference material does not establish the brand’s current independent operating status, product availability, or whether all of its original services remain active.

History

WhoSay emerged in 2010 amid growing concern among entertainers and talent representatives that social networks were becoming the primary distribution channels for celebrity photographs, videos, announcements, and promotional material. Although these networks offered enormous reach, they also controlled account infrastructure, audience data, presentation, and much of the surrounding commercial environment. Former Getty Images executive Steve Ellis worked with Creative Artists Agency to create a service that would give public figures more control over the material associated with their names and careers. Founded in Los Angeles in March 2010, WhoSay was financed by CAA, Amazon.com, Comcast, Greylock Partners, High Peak Ventures, and other investors. CAA and Amazon were described as minority stakeholders. The company's initial mission was not to create another broad social network but to provide an operating layer for influential users. Approved clients could publish from a central interface to several external networks, while copyright branding and related controls were intended to reinforce their rights in the content. The concept was sometimes compared with a celebrity magazine produced by the people appearing in it. The platform used an invitation-only model. It accepted talent beyond CAA's own client roster, but did not allow ordinary consumers to establish accounts. That decision kept the product focused on celebrity publishing and avoided direct competition with mass-market networks. It also meant that consumers generally reached WhoSay pages through links from a celebrity's other social accounts. The absence of a standard search function further emphasized that WhoSay was an infrastructure and publishing service rather than an independent discovery-oriented community. Tom Hanks became an early high-profile user roughly three months after the service launched. During its first several years, WhoSay remained relatively quiet while building a reported roster of around 1,500 actors, musicians, artists, and other public figures. Publicly cited users included entertainers and media personalities such as Kelly Clarkson, Julia Louis-Dreyfus, Paula Patton, Kevin Spacey, Jim Carrey, John Cusack, Bill Maher, Johnny Knoxville, Chelsea Handler, Eva Longoria, Spike Lee, Enrique Iglesias, and Katie Couric. Users including Dylan McDermott and Chris Rock publicly valued the ability to distribute one post across several services without managing each network separately. WhoSay’s economic model linked its interests with those of its talent. Participating clients were not charged for access and could receive a portion of advertising revenue. The company also promoted the possibility of sharing registration-derived email data with talent, giving celebrities a more direct communications channel with their audiences. This approach addressed a central weakness of relying exclusively on third-party platforms: a celebrity could have reach without having a durable, portable relationship with fans. In September 2013 the company introduced a mobile application for consumers. By October of that year, its website was reported to draw 12 million monthly visitors. The company continued to combine celebrity publishing with editorial coverage, describing itself as a social celebrity magazine whose editorial staff kept users informed about entertainment news. In July 2014, Rob Gregory joined as chief revenue officer from Newsweek's The Daily Beast. His remit included developing premium advertising products and brand partnerships for the web and mobile businesses. By February 2015, WhoSay was reported to have accumulated 4.8 million unique users and was extending its services to corporate clients using celebrities in marketing. The resulting business sat at the intersection of talent management, social publishing, advertising technology, and influencer marketing. Campaign work included Lexus programming with Rosario Dawson around the 87th Academy Awards and Chevrolet's April Fool's Day #BestDayEver initiative, which used Olivia Wilde, Norman Reedus, Alec Baldwin, Ian Somerhalder, and Nikki Reed in surprise classroom appearances. Other named commercial partners included KFC, JCPenney, Dunkin' Donuts, and Crest. WhoSay's competitive set included theAudience, a celebrity-oriented digital media company associated with William Morris Endeavor. Its differentiation rested on rights management and celebrity control as much as on audience scale. Rather than ask celebrities to surrender their identity and publishing workflow to a new network, it sought to help them coordinate existing networks and monetize their own material. In January 2018, Viacom acquired WhoSay. Available reference material does not provide a complete account of the post-acquisition product roadmap, leadership, or operating status. The acquisition is the last clearly documented corporate milestone in the supplied sources, so the current status of the WhoSay brand and website remains uncertain.
