Leonid Radvinsky, the reclusive billionaire who acquired adult content platform OnlyFans and transformed it into a multibillion-dollar empire, has died of cancer aged 43, the company announced 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. “His family have requested privacy at this difficult time.”
Florida-based Radvinsky, a Ukrainian-American entrepreneur born in Odesa and raised in Chicago, purchased a 75 percent stake in Fenix International Limited — the London-based parent company of OnlyFans — in 2018, serving as its director and majority shareholder.
Under his ownership the platform surged in popularity during the Covid-19 pandemic, growing to some 377 million users and 4.6 million content creators worldwide.
The company recorded $1.4 billion in net revenue in 2024, taking a 20 percent commission on most creator earnings, and had been valued at around $5.5 billion in early-stage sale talks earlier this year.
Radvinsky, who held a bachelor’s degree in economics from Northwestern University, had a net worth valued at $3.8 billion as of last May, according to the Bloomberg Billionaires Index.
He had transferred his ownership stake into the LR Fenix Trust in 2024.
Beyond OnlyFans, Radvinsky ran Leo, a venture capital fund he founded in 2009 focused on technology investments. He was also known for philanthropic activities, including support for cancer research and open source projects.
