Leonid Radvinsky, who built OnlyFans into a $5.5 billion company used by 300 million people, died at 43 after a long illness. His shares now sit in a trust.
Leonid Radvinsky, the Ukrainian-born billionaire who owned OnlyFans and built it into a platform used by 300 million people, died on March 23, 2026, at age 43 after what the company described as "a long battle with cancer." He was almost certainly the most powerful person in the creator economy that most people had never heard of — and that anonymity was deliberate.
OnlyFans said Leo "passed away peacefully," and that was about as much as anyone got. No long eulogy. No press conference. It was fitting, in a way, for a man who spent years avoiding the spotlight even as his creation reshaped entire industries.
Here's the thing that surprised a lot of people when they first learned about Radvinsky: he wasn't the guy who started OnlyFans. The platform was originally founded in 2016 by a British entrepreneur named Tim Stokely. It was a modest operation — a subscription-based site where creators could charge fans for exclusive content. Think fitness coaches and musicians, mostly. The adult content angle wasn't really the original pitch.
“Here's the thing that surprised a lot of people when they first learned about Radvinsky: he wasn't the guy who started OnlyFans.”
Radvinsky entered the picture in 2018, buying a 75 percent stake in Fenix International, the London-based parent company behind OnlyFans. By then, he already had deep roots in the adult internet business. He'd founded MyFreeCams back in 2004, one of the largest cam sites in the world. Before that — and this part often raises eyebrows — he'd run a string of websites in the early 2000s that sold what were advertised as "hacked" passwords to adult sites. One of them, Ultra Passwords, was reportedly pulling in $1.8 million a year.

So when he took over OnlyFans, Radvinsky understood the mechanics of the adult internet better than almost anyone alive.
What happened next was explosive growth. Under his ownership, OnlyFans became the defining platform of the creator economy — at least the part of it that traditional Silicon Valley wouldn't touch. The numbers tell the story pretty clearly: revenues exceeded a billion dollars annually, creators collectively earned billions more, and the platform's commission model — a 20 percent cut on everything — made Radvinsky staggeringly wealthy. Forbes pegged his net worth at roughly $4.7 billion.

But the growth came with controversy. In 2021, the platform briefly announced it would ban sexually explicit content, reportedly under pressure from banking partners and payment processors. The backlash was immediate and ferocious. Creators who had built their entire livelihoods on the platform felt blindsided. OnlyFans reversed the decision within a week, but the episode exposed just how precarious the relationship between adult content and mainstream financial infrastructure really was.
Radvinsky himself stayed almost entirely silent through all of it. He gave no interviews. He made no public statements. He didn't have a Twitter account or a LinkedIn profile. The few photographs that circulated were years old. For a man sitting atop one of the most culturally significant tech platforms of the decade, he was essentially invisible.
Born in Odessa, Ukraine, Radvinsky's family emigrated to Chicago when he was a child. He graduated summa cum laude from Northwestern University in 2002 with an economics degree. By then, he'd already been building websites for years — his first company, Cybertania Inc., was incorporated when he was 17. He taught himself BASIC programming as a teenager using his grandfather's computer equipment. The guy was building businesses before he could legally vote.
In 2009, he founded a venture capital fund called Leo, focused on technology investments. But the real money, the real legacy, was always OnlyFans.
His death opens up genuinely complicated questions about what happens next. In January, Reuters reported that OnlyFans had been exploring a sale — specifically, a potential deal with Architect Capital that would have valued the company at roughly $5.5 billion, including debt. With Radvinsky gone — and his shares held in something called the LR Fenix Trust since 2024 — the ownership structure enters uncharted territory.

There are also bigger questions about the creator economy itself. OnlyFans didn't just give adult performers a new way to make money. It shifted the entire power dynamic between creators and platforms. The idea that individuals could monetize their own audiences directly, without studios or intermediaries taking the lion's share — that was genuinely transformative, whatever you think about the content itself.
Radvinsky saw that before most people did. He bet on it with his own money, and he was spectacularly right.
The man who changed porn — and arguably changed the economics of online creation more broadly — is gone at 43. The arguments about what he built, and what it means, are just getting started.
Leonid Radvinsky died at age 43 after a long battle with cancer. The company stated that he "passed away peacefully." No further details about the specific type of cancer were publicly disclosed.
Who will own OnlyFans now that Radvinsky has died?
Radvinsky transferred his Fenix International shares to the LR Fenix Trust in 2024. The exact succession plan remains unclear. In January 2026, Reuters reported that OnlyFans had been exploring a potential sale to Architect Capital in a deal valuing the company at approximately $5.5 billion.
What was Leonid Radvinsky's net worth?
According to Forbes' real-time billionaires list, Radvinsky's net worth was approximately $4.7 billion, primarily derived from his ownership stake in OnlyFans and its parent company Fenix International.
