Leonid Radvinsky, the Ukrainian-born entrepreneur who transformed a modest British website into the adult-entertainment giant OnlyFans, has died at 43. He purchased a majority stake in 2018, leveraging social media and influencer marketing to scale the platform. By 2025, OnlyFans generated an estimated $7 billion annually, a meteoric rise from its $2 million yearly revenue in 2018.

Radvinsky introduced collaborative features and incentivized creators to cross-promote on Instagram, fostering an ecosystem that now boasts over four million creators and 370 million users. His strategies capitalized on the pandemic, driving daily user growth to 500,000 by late 2020 and generating $200 million in creator payouts that year. Despite controversies over business practices and regulatory fines, his impact on the online pornography market is undeniable.
