No, Radvinsky did not create OnlyFans; he only bought the platform in 2018 from Guy and Tim Stokely, the latter of whom is credited as the founder. In a past LinkedIn post, Stokely wrote about how he created OnlyFans.

“Like many founders, I didn’t start with a team, a playbook, or funding. I started with a problem: creators were generating huge value online, but had little control over how they earned from it,” he wrote. “Platforms owned the audience. Algorithms decided visibility. Advertisers controlled the money. We built OnlyFans to change that and put creators in charge of their income through direct fan subscriptions. They had more control and could monetise much more efficiently.”
