OnlyFans founder is gone, 43 years old, cancer.

Leonid Radvinsky. Most people haven't heard this name.
But he might be one of the most money-making internet entrepreneurs of the past five years. In 2018, he bought a 75% stake in OnlyFans for less than $50 million. By 2024, he was taking home $701 million in dividends alone in a single year.
Forbes estimated his net worth between $4.7 billion to $7.8 billion at the time of his death. He almost never gave interviews, had no public social media, and his own employees rarely saw him. A true behind-the-scenes player.

But what I want to discuss today isn't his life story.
I want to talk about OnlyFans' business model.
The platform essentially does one thing: stands between creators and fans, takes 20%, with creators responsible for content production, fan maintenance, and traffic acquisition, while the platform provides payment channels and infrastructure.
Then it takes one-fifth of every single transaction. In 2023, the platform's total transaction volume exceeded $6.5 billion, with company profits exceeding $1 billion.
Radvinsky personally took home $472 million in dividends.

This structure is clean enough to make people jealous. No inventory. No massive content moderation costs (creators bear them). No copyright disputes.
Doesn't even need a recommendation algorithm. Plainly put, this is a rent-collection machine.

You can think this industry is controversial. But from a business structure perspective, Radvinsky got three things right:

First, he found an industry with extremely poor payment infrastructure (adult content) and solved the core pain point.

Second, he made creators bear almost all operational costs, with the platform only serving as a conduit.

Third, he never stepped forward, never branded himself, letting the platform become synonymous with the category.

He left at 43, leaving behind a machine that makes $1 billion a year.

You can disagree with this industry, but this business model is worth studying for everyone building platforms. What is true platform economics? It's not about how many users you have. It's about how many transactions you stand in the middle of, and how much value you can extract.
