Leonid "Leo" Radvinsky, the low-profile owner of the London-based OnlyFans platform, has died of cancer at the age of 43. Radvinsky acquired control of OnlyFans' parent company, Fenix International, in 2018 and helped transform the site into a major player in online adult content by allowing creators to charge subscribers directly. OnlyFans has paid out some $25 billion to content creators since its 2016 inception, and the platform now reports more than 4.6 million creators, 377 million users, and $1.4 billion in annual revenue.
