In a remarkable ascent that has captivated the tech world, Lucy Guo, a 30-year-old entrepreneur, has eclipsed pop superstar Taylor Swift to become the youngest self-made woman billionaire globally. According to Forbes, Guo’s net worth now stands at an estimated $1.3 billion, primarily stemming from her 5% stake in Scale AI, a company she co-founded in 2016.
Who Is Lucy Guo?

Raised in the San Francisco Bay Area and born to Chinese immigrant parents, Guo started learning to code in middle school before leaving Carnegie Mellon University to accept a $100,000 entrepreneurial fellowship from billionaire investor Peter Thiel. She kept her equity, which is now the source of her billion-dollar status, even after being fired from Scale AI because of conflicts among co-founders.
Guo’s rise puts her ahead of Taylor Swift, who was the youngest person on the list until 2023, when she became a billionaire at the age of 33. Swift has been demoted to the second position in the youngest category, despite having a net worth of $1.6 billion as of June 2025, according to Forbes.
A College Dropout Who Became A Thiel Fellow

Guo studied computer science for a short time at Carnegie Mellon University before leaving in 2014 to accept the Thiel Fellowship, a $100,000 grant that encourages young people to choose entrepreneurship over traditional schooling.

Guo and Alexandr Wang, who was 19 at the time, co-founded Scale AI in 2016 when Guo was 21. The business specializes in offering top-notch labeled data for AI application training, which is essential to the advancement of AI technology. Guo kept a sizable share in the business even after leaving it in 2018 due to strategic differences. Her 5% ownership in Scale AI was valued at about $1.2 billion as of 2025, when the company’s valuation increased dramatically to $25 billion.

In 2022, Guo introduced Passes, a platform positioned as a rival to OnlyFans that enables creators to profit from their fan followings using tailored interactions. Passes incorporates AI technology, enabling creators to interact with followers via virtual personas. The platform immediately became popular, drawing well-known creators and raising $50 million in just two years.
A class-action lawsuit alleging the inadvertent distribution of child sexual abuse material (CSAM) on the platform threw Passes into controversy in 2025. The allegations rocked tech and media circles, casting doubt on Passes’ “ethical monetization” pledge and raising concerns about the security measures underlying its AI moderation.
To deny the plaintiff any protections provided by the Passes against the exploitation of a minor, the complaint claimed that Guo personally interfered in bypassing the company’s strict internal safety measures designed for social media content creators between the ages of 15 and 17.
Guo isn’t exactly leading a quiet billionaire lifestyle despite the serious charges and close surveillance. Guo appreciates the more elegant, and perhaps lavish, aspects of life.
