Who was Leonid Radvinsky? All about life and networth of the reclusive OnlyFans billionaire who died at 43

Leonid Radvinsky, the low-profile billionaire behind OnlyFans who transformed the platform into a global adult-content powerhouse, has died at the age of 43 after battling cancer, the company confirmed on Monday.

The Ukrainian-American entrepreneur acquired Fenix International — OnlyFans’ parent company — in 2018 from founder Tim Stokely. As majority owner and a board director, Radvinsky played a decisive role in reshaping the platform’s direction.

Under his leadership, OnlyFans evolved from a niche subscription service into a cultural and commercial giant. The platform now boasts over 300 million users and generates more than $1 billion in annual revenue, largely driven by creators, adult performers, and influencers monetising exclusive content.


“We are deeply saddened to share that Leo Radvinsky has passed away peacefully following a long battle with cancer,” an OnlyFans spokesperson said.

His death raises uncertainty over the company’s future ownership. Radvinsky’s shares have been held in the LR Fenix Trust since 2024. At the time of his passing, his net worth was estimated at around $4.7 billion, according to Forbes.

Earlier this year, reports suggested that OnlyFans was exploring a potential sale of a majority stake to investment firm Architect Capital in a deal valuing the company at roughly $5.5 billion, including debt.

The platform saw explosive growth during the COVID-19 pandemic, as millions turned to digital content and alternative income streams. OnlyFans typically takes a 20% cut from creator earnings.

Beyond OnlyFans, Radvinsky also founded Leo, a venture capital firm launched in 2009, focused on technology investments.

Born in Odesa, Ukraine, Radvinsky later moved to Chicago, where he grew up. He is survived by his wife, Katie Chudnovsky, and their four children.

A closer look at his rise

Radvinsky purchased a majority stake in OnlyFans in 2018 from British founders Guy and Tim Stokely, who had launched the platform in 2016. While the founders built the base, it was Radvinsky who scaled it into a global phenomenon.

His wealth surged during the pandemic-era boom, earning him a spot on the Forbes billionaires list in 2021. By March 2026, his fortune had more than doubled to $4.7 billion.

By 2024, OnlyFans reported over 4.6 million creators and approximately 377 million users, with revenues reaching $1.4 billion. Since 2021, Radvinsky reportedly paid himself around $1.8 billion in dividends.

Despite his massive influence, Radvinsky remained intensely private throughout his life — a billionaire who built one of the internet’s most talked-about platforms, largely out of the spotlight.
