OnlyFans owner Leonid Radvinsky has died at age 43 after a secret battle with cancer, the porn streaming platform said Monday.
“We are deeply saddened to announce the death of Leo Radvinsky. Leo passed away peacefully after a long battle with cancer,” the company wrote in a statement, adding that his family were requesting privacy during the difficult time.
The Ukrainian-American entrepreneur acquired Fenix International, the company that owns and operates OnlyFans, in 2018, and remained a director and the majority shareholder for the next 8 years.
His contributions – including offering adult content creators a platform to reach their audience directly through subscriptions and keep 80% of their revenues – revolutionized the porn industry.
Sophie Rain – an adult content creator and fan favorite on the streaming site, where she earned a mind-boggling $95 million between 2023 and 2025 – thanked Radvinsky for changing her life in an emotional tribute.
“I don’t even know how to put this into words. That man built something that changed my entire life. Like, I grew up on food stamps and now I can take care of my whole family because of a platform he created. I will never forget that,” she told The Post.
“Before OnlyFans I was waitressing and barely making rent. That platform gave me everything. And that doesn’t happen without someone building it in the first place,” said Rain, 21.
Despite his status as a billionaire, Radvinsky kept a famously low profile – even leaving behind only a single, widely-circulated image of himself.
He was a prominent donor to medical causes, and in 2024, he and his wife were major supporters of a $23 million grant program for cancer research through a gastrointestinal research foundation, according to a Wall Street Journal report.
His attorney and philanthropist wife, Yekaterina “Katie” Chudnovsky, who had sat on the board of the foundation for over a decade, appeared to allude to her husband’s health battles during a speech at the gala.
“Because of the scientists behind the research we are funding, one miracle followed another,” Chudnovsky said, as reported by the Wall Street Journal at the time.
“The advances will forever change the face of cancer treatment. And Leo’s here tonight proving that science and miracles go hand in hand,” she stated.
The news of Radvinsky’s death came as a shock to the public — including the top stars on his platform. But he actually died days earlier, and had been preparing the company for it for months, a pal said.
“Insiders knew [Radvinsky] had been dealing with health issues for some time, and while his passing is tragic, he left behind a company that was fully prepared and resilient,” said Andy Bachman, the CEO of Creators Inc., which works closely with OnlyFans stars.
“His passing wasn’t sudden, so there was a lot of preparation and he passed a few days before the media found out, so there was no interruption to the business,” Bachman told The Post.
According to Radvinsky’s personal website, the late businessman also made philanthropic donations to Memorial Sloan Kettering Cancer Center, The University of Chicago Medicine and EB Research Partnership, a global organization dedicated to funding research to treat and cure the rare genetic disease Epidermolysis Bullosa.
Born in Odesa to Jewish Ukrainian parents and raised outside Chicago, Radvinsky graduated from Northwestern University with a degree in economics – and an appetite for scalable adult-tech models, which would eventually lead him to OnlyFans.
Among his early ventures were websites that claimed to offer hacked passwords to porn sites.
Later, he would register hundreds of domain names — many of them X-rated or referencing celebrities of the early 2000s.
In 2004, he launched MyFreeCams, one of the early porn streaming sites, where users paid performers for private shows.
As of March 10, Forbes estimated Radvinsky’s net worth at a whopping $4.7 billion, making him one of the richest people in the world. Between 2021 and early 2025, Radvinsky collected nearly $1.3 billion in dividends from OnlyFans, where he was the director and majority shareholder.
His shares in the company have reportedly been held in a trust.
He was previously trying to sell his stake for $8 billion — though he had trouble finding a bank to broker the deal.
London-based Fenix International was in talks last year over a potential acquisition by a group led by Forest Road, an LA-based investment bank and advisory firm, although the talks collapsed for unknown reasons.
Despite leading such a quiet life, property records show Radvinsky splurged on a next-level-ritzy Miami condo worth almost $19 million, according to an online estimate. It’s unclear how much he paid for the nearly 6,000-square-foot condo in the oceanfront Turnberry Ocean Club Residences – where units come with exclusive memberships to a private marina, an airport and two championship golf courses.
