Leonid Radvinsky (May 30, 1982 – March 2026) was a Ukrainian-American businessman and computer programmer, widely known as the majority owner of OnlyFans and founder of MyFreeCams. Based in the United Kingdom, he built a multi-billion-dollar fortune through adult entertainment platforms and early internet ventures.
At the time of his death in March 2026, Radvinsky had an estimated net worth of $4.7 billion, according to Forbes. His influence reshaped the global creator economy, particularly in subscription-based content monetization.
Early Life and Education
Leonid Radvinsky was born on May 30, 1982, in Odesa, Ukrainian SSR (now Ukraine), into a Jewish family. During his childhood, his family emigrated to Chicago in the United States.
He later attended Northwestern University, graduating in 2002 with a degree in economics. His early exposure to internet business opportunities during the late 1990s laid the foundation for his future ventures.
Early Career and Online Ventures
Radvinsky began his entrepreneurial journey at the age of 17. In 1999, he helped incorporate Cybertania Inc., a website referral business.
During the late 1990s and early 2000s, he developed multiple websites such as Password Universe, Working Passes, and Ultra Passwords. These platforms were marketed as offering access to restricted or “hacked” adult content. However, reports later indicated there was no evidence of actual illegal content being distributed.
Ultra Passwords reportedly generated up to $1.8 million annually, showcasing his early success in online monetization models.
In 2004, he founded MyFreeCams, an adult live-streaming platform that became one of the most recognized cam sites globally.
That same year, Microsoft filed a lawsuit against him for allegedly sending deceptive emails to Hotmail users. The case was eventually dismissed.
Ownership of OnlyFans
In 2018, Radvinsky acquired a 75% stake in Fenix International Ltd., the parent company of OnlyFans, from founders Tim Stokely and Guy Stokely.
Following the acquisition, OnlyFans increasingly focused on NSFW (not safe for work) content and rapidly expanded its global user base.
By November 2023, OnlyFans generated over $6.6 billion in annual revenue, with growth averaging 19 percent per year.
Radvinsky personally received $284 million in 2021, $338 million in 2022, $472 million in 2023, and $701 million in 2024.
Under his leadership, OnlyFans became a dominant platform in the creator economy, enabling millions of content creators to monetize subscriptions directly.
Venture Capital and Investments
Radvinsky founded a venture capital fund known as Leo in 2009. The fund focused primarily on technology startups.
Notable investments included B4X, an Israel-based technology company, and Pleroma, a decentralized social networking software.
He also supported the Elixir programming language ecosystem, contributing to its growth and adoption.
Philanthropy
Radvinsky was actively involved in charitable initiatives throughout his life.
In 2024, he and his wife supported a $23 million cancer research grant program. He also contributed $5 million toward Ukraine relief efforts in 2022, along with donations to cancer research, animal welfare, and skin disorder research.
Organizations he supported included Memorial Sloan Kettering Cancer Center and the West Suburban Humane Society.
He publicly expressed interest in joining the Giving Pledge, committing to donate the majority of his wealth.
Political Activity
In 2023, reports suggested that Radvinsky and his spouse contributed $11 million to AIPAC, a pro-Israel lobbying organization. However, he disputed these claims.
Personal Life
Radvinsky was married to Katie Chudnovsky in 2008. The couple maintained a relatively private life despite his high-profile business success.
Death
Leonid Radvinsky died in March 2026 at the age of 43 after battling cancer. OnlyFans released a statement expressing deep sadness at his passing.
