Leonid Radvinsky, the secretive billionaire who transformed OnlyFans into a subscription-driven powerhouse of the adult entertainment industry, has died at 43 after a battle with cancer, the company said Monday.
“We are deeply saddened to announce the death of Leo Radvinsky. Leo passed away peacefully after a long battle with cancer,” an OnlyFans spokesperson said.
Radvinsky, a Ukrainian American entrepreneur, bought Fenix International the parent company of OnlyFans from founder Tim Stokely in 2018. He served as a director on Fenix’s board and was its majority shareholder. Under his ownership, the platform shifted from avoiding explicit content to embracing it, becoming an adults-only phenomenon with more than 300 million users and generating over $1 billion in annual revenue.
His Fenix shares have been held in the LR Fenix Trust since 2024. Forbes estimated his net worth at about $4.7 billion. Reuters reported in January that OnlyFans was exploring the sale of a majority stake to investment firm Architect Capital in a deal valuing the company at about $5.5 billion, including debt.
The platform surged in popularity during the pandemic as millions of people turned to online content while stuck at home. OnlyFans takes a 20% fee on most subscriptions and content sales.
Beyond Fenix, Radvinsky also ran Leo, a venture capital fund he founded in 2009 that invests primarily in technology companies.
He was born in Ukraine and grew up in Chicago.
