Leonid Radvinsky, the founder and owner of OnlyFans' parent company Fenix International Ltd., has died from cancer at the age of 43. Radvinsky, who acquired a controlling stake in OnlyFans in 2018, was instrumental in transforming it into a major platform for creators to monetize content directly from users. The platform, which takes a 20% cut from subscriptions and sales, reported $1.4 billion in revenue in 2024 with 4.6 million creators and 377 million users. At the time of his death, Radvinsky had transferred his equity into a trust and was in talks with Architect Capital to sell 60% of OnlyFans' equity, valuing the company at $5.5 billion. His passing raises questions about the future direction of the platform, which has been a significant player in the creator economy.
