Leonid Radvinsky, the 43-year-old Ukrainian-American entrepreneur who transformed OnlyFans into a global digital powerhouse, has died on March 23, 2026, after a prolonged battle with cancer. He acquired a majority stake in Fenix International, the parent company of OnlyFans, in 2018 and expanded the platform into a multi-billion-dollar force in the creator economy, supporting millions of creators across diverse fields. Under his leadership, OnlyFans grew to nearly 377 million users and generated over $1.4 billion in revenue by 2024. His net worth was estimated at $3.8 billion to $7.8 billion. Radvinsky’s passing raises questions about the platform’s future leadership and governance and the continuation of his philanthropic commitments, including a $23 million pledge to cancer research.
