MediaLink founder and advertising rainmaker Michael Kassan is suing United Talent Agency’s attorney Bryan Freedman for $125 million for allegedly trying to destroy his reputation and ability to compete by branding him a “pathological liar” who has a “mental disease,” new court papers show.

UTA bought MediaLink from Ascential Plc in December 2021 for the same amount — $125 million — bringing Kassan and the company’s 150 employees into the agency. But things soured between the advertising powerhouse and the agency’s CEO Jeremy Zimmer, allegedly over huge expense accounts and power struggles.
