Leonid Radvinsky, the reclusive billionaire entrepreneur who transformed OnlyFans into a global multi-billion-dollar powerhouse, has passed away at the age of 43. According to an official statement released by the company on Monday, 23 March 2026, Radvinsky died peacefully following a prolonged and private struggle with cancer. The platform’s parent company expressed deep sadness over the loss of its majority shareholder, while his family has formally requested privacy as they mourn his passing.
A Ukrainian-American businessman born in Odesa and raised in Chicago, Radvinsky was a graduate of Northwestern University with a degree in economics. He made a significant impact on the digital economy in 2018 when he acquired a 75 per cent stake in Fenix International Limited, the London-based entity that owns OnlyFans. Under his strategic direction, the subscription-based platform experienced explosive growth, particularly during the COVID-19 pandemic, as it became a primary source of income for millions of content creators worldwide.
By 2024, OnlyFans had reached a massive scale, reporting approximately 377 million users and 4.6 million creators on the platform. The company’s financial performance under Radvinsky’s leadership was equally remarkable, recording a net revenue of US$1.4 billion in 2024 alone. The business model, which involves taking a 20 per cent commission on creator earnings, has positioned the company as one of the most profitable entities in the creator economy, with a recent valuation estimated at roughly US$5.5 billion.
As of May 2025, the Bloomberg Billionaires Index valued Radvinsky’s net worth at US$3.8 billion, a figure that reflected both the success of OnlyFans and his broader investment portfolio. In 2024, he took steps to secure the future of his holdings by transferring his ownership stake into the LR Fenix Trust. Beyond his role in the adult content industry, Radvinsky was a prolific technology investor through his venture capital fund, Leo, which he established in 2009 to focus on emerging tech ventures and open-source software.
Radvinsky was also known for his philanthropic efforts, which often remained as private as his personal life. His charitable contributions notably included significant support for cancer research, animal welfare, and various open-source technology projects. While his death marks the end of an era for OnlyFans, the structural changes he implemented, including the transition of his shares into a trust, suggest that the platform is prepared to continue its operations as it navigates this period of leadership transition.
