Onlyfans

OnlyFans has been a money-printing machine for its secretive billionaire owner Leonid Radvinsky. Investors were puzzled by an obscure debt fund’s pitch to buy him out, until they learned of his terminal cancer diagnosis.

The owner of the social media subscription site best known for hosting adult content has now earned over $1.8 billion in dividends since buying the website in 2018.

OnlyFans was a little-known U.K.-based company before porn entrepreneur Leonid Radvinsky bought it in 2018. Now he’s a new member of The Forbes 400.
