OnlyFans billionaire Leonid Radvinsky's widow has taken control of the company he built into a $3 billion empire

Yekaterina Chudnovsky, the widow of Leonid Radvinsky, has replaced her late husband as the person with significant control of Fenix International, the UK-registered holding company behind OnlyFans, according to filings published Thursday with the UK's Companies House.

The filings show that Chudnovsky, who goes by Katie, was listed as the controlling party in March, the same month Radvinsky died from cancer at the age of 43. OnlyFans confirmed his death in a brief statement at the time, saying he had passed away peacefully after a long battle with cancer and requesting privacy for the family. Radvinsky died on March 20, 2026.

Bloomberg described the transfer as the latest example of a "sideways" inheritance, through which wealthy individuals pass control of business empires to their spouses rather than children or other heirs. Radvinsky and Chudnovsky married in 2008 and have four children. Control of Fenix International now sits with a family trust led by Chudnovsky, who has been overseeing the company's affairs since her husband's illness and death.

Radvinsky bought OnlyFans from its British founders Tim Stokely and his father Guy Stokely in 2018, paying an undisclosed sum for the parent company Fenix International. At the time, the platform was a niche subscription service. What followed was one of the fastest accumulations of dividend income in modern internet business history. He received $472 million in dividends from the site in 2023, up from $338 million in 2022 and $284 million in 2021. In 2024, OnlyFans paid him $701 million. His total dividend intake from the platform over a three-year stretch exceeded $1 billion.

OnlyFans had annual revenues in excess of $6.6 billion as of November 2023, with revenues growing 19% per year. The platform reached 305 million subscribers and 4.1 million content creators by the end of its 2023 fiscal year. The US accounted for the majority of its revenue. Despite owning one of the most visited sites on the internet, Radvinsky was conspicuously private throughout his ownership, rarely giving interviews, avoiding the public business circuit and keeping his family life out of the press.

The transition of control comes at a significant commercial moment. A stake sale that could value OnlyFans at more than $3 billion is under discussion, with an agreement expected to be struck as early as next month, according to three people with knowledge of the situation. The deal is structured to allow further stake sales in the future and would mark the first time outside investors have held equity in the platform since Radvinsky consolidated full ownership. Chudnovsky has been overseeing the sale process since her husband's death.

Radvinsky was born in Odesa in what was then the Ukrainian Soviet Socialist Republic on May 30, 1982. His family emigrated to the United States when he was a child and settled in Chicago. He studied economics at Northwestern University, graduating in 2002, and began building internet businesses in his early twenties. Before OnlyFans, he ran MyFreeCams, an adult webcam site that gave him both technical infrastructure and an understanding of the economics of online adult content monetisation. In 2024, the couple were major public supporters of a $23 million grant program for cancer research announced at a gastrointestinal research foundation gala. The illness that eventually took his life had been his motivation for that giving.

Chudnovsky now controls what Forbes estimated at the time of Radvinsky's death to be a business worth several billion dollars, generating hundreds of millions in annual profit from a platform that permanently reshaped the economics of digital content creation. What she does with that control, whether she completes the partial stake sale, pursues a full exit or holds the asset as a long-term income generator for the family trust, will define one of the more consequential succession decisions in recent tech business history.
