The reclusive billionaire owner of the world's largest adult modeling service, Ukrainian-American businessman Leonid Radvinsky, has died at the age of 43.
UK-based modeling site OnlyFans announced his death in a statement, which reads: “We are deeply saddened to announce the death of Leo Radvinsky. Leo passed away peacefully after a long battle with cancer.
They added that 'his family have requested privacy at this difficult time.' The Ukrainian born and Chicago educated businessman bought a 75 percent share in Fenix International Limited, the company behind the site, in 2018.
Radvinsky's acquisition turned OnlyFans further towards not safe for work content that quickly turned the adult modeling service into one of the UK's largest tech firms generating billions in revenue every year.

Five years after Radvinsky's takeover of the business from Brit Tim Stokely, OnlyFans was generating $6.6 billion in annual turnover as people across the world started creating profiles and sharing paid-for content on the platform.
With his majority stake, Radvinsky received a $472 million dividend payout in that year alone, with his total dividends in the eight years since his purchase nearing $2 billion.
His death from cancer throws the future of the controversial company into jeopardy, according to Bloomberg reports, with an early exploration of a potential buyout by a private investment firm in January supposedly valuing the business at $5.5 billion.
Who was Leonid Radvinsky?
Born in Odessa, Ukraine, in 1982, to a Jewish family, the Radvinskys would emigrate to Chicago when Leonid was young. He would go on to gain an economics degree as a class valedictorian at Northwestern University, before starting his journey to becoming a billionaire.
Much of Radvinsky's early success came from business that generated profit from website referrals, initially creating sites that aggregated passwords for pornography websites that would generate him money with every click. One website alone made him $1.8 million in a year, according to Business Insider.

Staying in this lane, Radvinsky founded an early adult camming website called MyFreeCams in 2004. The profits from these businesses then led him to found a venture capital fund in 2009 that focused primarily on tech and social media start ups.
Nine years later, the Ukrainian-American would make the acquisition that launched his wealth into the stratosphere with OnlyFans, with the billionaire never revealing how much he paid for the UK modeling site that would explode in use during the pandemic.
But while he was generating billions in share dividends, according to the statement from his company, at some undisclosed point Radvinsky was diagnosed with a form of cancer. As he never gave a public interview, little other information is known about his activities in recent years.
However, in 2024, Radvinsky and his wife created a $23 million grant program for cancer research projects, which they announced at an event for research into gastrointestinal health.
