Leonid Radvinsky, the billionaire owner of the social media platform OnlyFans, has died at the age of 43. The Ukrainian-American passed away following a secret battle with cancer, according to the company.
“We are deeply saddened to announce the death of Leo Radvinsky. Leo passed away peacefully after a long battle with cancer,” the company said in a statement. “His family have requested privacy at this difficult time.”
In 2018, Radvinsky, who was born in Ukraine and grew up in Chicago, bought Fenix International, the company that owns and runs OnlyFans,. He continued to serve as its director and primary stakeholder after the purchase.
OnlyFans is a social media site where creators may share images and videos in exchange for monthly fees or tips from users. Creators also share live streams, send personalized messages, and respond to direct requests. In return for hosting the content, the company collects 20% of all payments.
So who owns OnlyFans now?
According to a 2025 Reuters report, Radvinsky was in negotiations to sell OnlyFans to a group of investors for around $8 billion. An initial public offering was also reportedly being considered. In its most recent Companies House filing, the company reported $1.4 billion in revenue and more than 377 million subscribers.
According to the Forbes real-time billionaires list, the LR Fenix Trust has held Leonid Radvinsky’s OnlyFans shares since 2024. Additionally, Radvinsky oversaw Leo, a venture capital firm he established in 2009 with a primary focus on investments in tech firms. As of October 2025, he had a net worth of about $7.8 billion.
On his personal website, he stated that he hoped to sign the Giving Pledge, a public pledge by affluent people to donate the bulk of their income to charitable organizations.
According to the Daily Star, Radvinsky had been in talks with investment company Architect Capital to sell the majority of the site. The status of those talks is currently unclear.
With his passing, industry insiders suggest the company may expand into mainstream entertainment and form partnerships with larger media companies.
