In April 2025, Lucy Guo became the youngest female self-made billionaire after Meta paid $14.3 billion for a 49% stake in Scale AI, the company she cofounded with Alexandr Wang in 2016.
Though Guo had left the company—which builds infrastructure and software to create AI applications—over disagreements with Wang in 2018, she retained her 5% stake in the business, which skyrocketed in value after Meta’s investment.
In 2022 she reemerged with Passes, a platform that helps creators monetize their social media followings by selling access to exclusive offerings—from products and merch to pay-by-the-minute private phone calls. As of February, the company has raised a total of $49 million.
Guo tells me that Passes is growing—its payments to creators have totaled nine figures so far—and profitable. But its expansion has come with some controversy. In 2024, Passes was sued by rival platform Fanfix over alleged anti-competitive practices, and since February it has been facing a class-action lawsuit accusing it of distributing child pornography.
