Yekaterina Chudnovsky, online biographies say, is a mother-of-four who “enjoys spending time with her family and teaching them the importance of giving back and helping others”. They add that Ukrainian-born Chudnovsky, known as Katie, finds sanctuary in walks on the beach.

In interviews, Chudnovsky has spoken warmly about her commitment to philanthropy, her dedication to support cancer research and her work as a lawyer for an unnamed global technology firm. Pornography is never mentioned.

Now, it may become unavoidable. After the death of Chudnovsky’s husband, Leonid Radvinsky, from cancer last week at the age of 43, she is now understood to have a controlling interest through a family trust in the London-based adult content site, OnlyFans.

Chudnovsky is set to have a crucial role in deciding what happens to the business that made her husband a billionaire before he turned 40. The family stake is valued at about $5.5bn (£4.1bn).

Chudnovsky’s views on pornography will determine the site’s future business model, and whether it continues to generate huge sums of money by taking a 20% cut from the earnings of about 4 million content creators globally, a large proportion of whom generate money for the business by undressing and performing explicit content on the platform.

OnlyFans has tried to position itself as one of Britain’s greatest tech success stories, preferring to be seen as a social media platform than as an adult business. It employs only 42 people, and yet managed to generate $7.2bn in 2024.
