The billionaire owner of adult content website OnlyFans, Leo Radvinsky, has died aged 43 from cancer.
A spokesperson for the site told the Daily Mail in a statement that the company was ‘deeply saddened’.
‘Leo passed away peacefully after a long battle with cancer,’ the spokesperson said. ‘His family have requested privacy at this difficult time.’
An obituary for Radvinsky online showed he passed away in Pomano Beach, Florida, near to where he lived in with his family in a $4 million mansion in Boca Raton.
The Ukrainian-American businessman had a net worth estimated at $4.7 billion, largely due to his firm Fenix International Limited’s majority ownership of OnlyFans.
He was a director and the majority shareholder of the company, and he was also a renowned philanthropist and angel investor.
Radvinsky took over OnlyFans in 2018 from the Stokely family in the United Kingdom, and the site expanded rapidly under his watch.
In 2024, users spent a record $7.2 billion on the subscription platform, and Radvinsky paid himself $1.8 billion in dividends from 2021 to 2025, per Bloomberg.
Radvinsky had been attempting to sell the pornography site last year, but sources told the New York Post at the time that he was struggling to find a buyer due to its X-rated business model.

Radvinsky’s net worth soared during the COVID-19 pandemic, as lockdowns drove creators and consumers to his subscription-based online platform.
The platform attracted celebrity creators including Blac Chyna and Bella Thorne, who made millions per month by posting risqué content for their fans.
Despite raking in huge sums from the company, including taking home $472 million in dividends in 2023, Radvinsky was reportedly looking to sell OnlyFans.
Insiders reportedly said he was struggling to find a buyer despite huge profits, because its pornographic content capped the price tag to just $2.4 billion.
In January, Reuters reported that he may have eventually found a buyer, as OnlyFans was exploring a majority-stake sale to investment firm Architect Capital.
He was notoriously reclusive, and lived in a lavish $4 million mansion in Florida with his wife.
His cancer battle was largely unknown to the public, and he was renowned for keeping a low profile despite the worldwide success of his pornography platform.
In 2024, Radvinsky and his wife sparked controversy with his site’s members after he pledged $11 million to the pro-Israel lobby, the American Israel Public Affairs Committee (AIPAC), according to a donor list reported by The Lever.

Following news of Radvinsky’s death, his estranged father Saveliy told Ukrainian news outlet Baza that he was an ‘incredibly talented boy.’
Referring to him by his childhood nickname ‘Lenya’, he said he wrote his first computer code aged nine, and said his family were not surprised to see him get into the adult entertainment world.
‘And he was always drawn to pornography, was involved in dating sites, all that stuff,’ he said.
Childhood friend Darryl Monroe told the Chicago Sun Times that they would play chess together as kids, but said Radvinsky was so intelligent at the game it was ‘like I had to throw up.’
‘I kept sinking down… When I heard he was from Russia, I thought, `I’ll have to play real hard’,’ he said.
