Leonid Radvinsky, a Ukrainian-American entrepreneur who was the owner of the adult content platform OnlyFans, has died.
In a statement, the company confirmed his death from cancer at the age of 43.
A spokesman for OnlyFans said: "We are deeply saddened to announce the death of Leo Radvinsky.
"Leo passed away peacefully after a long battle with cancer.
"His family have requested privacy at this difficult time."
Mr Radvinsky acquired Fenix International Limited, the parent company of OnlyFans, in 2018 and served as its director and majority shareholder.
He also ran Leo, a venture capital fund he founded in 2009 that focuses primarily on investments in technology companies.
OnlyFans, founded in 2016 by British entrepreneur Tim Stokely, surged in popularity during the COVID pandemic as lockdowns drove creators and consumers online.
It turned the subscription-based platform into a mainstream source of income and entertainment globally.
In January, the Reuters news agency reported that OnlyFans was exploring the sale of a majority stake to investment firm Architect Capital in a deal valuing the company at about $5.5bn (£4.1bn), including debt.

The strong financial performance by the platform led to significant cash windfalls for Mr Radvinsky.
Last August, it was revealed Mr Radvinsky was paid £522m in dividends in 2024.
The streaming site had also seen its user numbers jump by almost a quarter.
OnlyFans reported that the total number of creator accounts producing content for the site grew by 13% to 4.6 million as more people used it as an opportunity to make a living.
