Leonid Radvinsky, the billionaire owner of the content platform OnlyFans, has passed away at the age of 43. A spokesperson for the company confirmed that Radvinsky died peacefully on March 23 following a lengthy battle with cancer. Born in Odessa, Ukraine, and raised in Chicago, the tech entrepreneur was a major figure in the digital economy. His family has requested privacy at this time.
He studied economics at Northwestern University and founded several internet-based businesses before acquiring a majority stake in Fenix International Limited, the parent company of OnlyFans, in 2018.
Under Radvinsky’s ownership, OnlyFans underwent a massive transformation. Initially a niche subscription site founded by Tim Stokely in 2016, the platform exploded in popularity during the COVID-19 pandemic. By 2024, it was generating over $7.2 billion in annual subscriber payments, with Radvinsky himself reportedly earning approximately $1.9 million per day in dividends.
Despite his immense wealth, Radvinsky remained a deeply private figure, rarely giving interviews. He was also a prolific angel investor and philanthropist, notably supporting medical research and humanitarian efforts in Ukraine. His philanthropy included donations to the Memorial Sloan Kettering Cancer Center, according to his website.
His death leaves significant questions regarding the future of OnlyFans. Ownership of his shares had been moved to a trust in 2024, and the company had recently been exploring a majority stake sale valued at roughly $5.5 billion.
At the time of his death, Forbes estimated his net worth to be around $4.7 billion.
