Lucy Guo, 30, becomes the world’s youngest self-made woman billionaire
In a development that went largely under the radar, Lucy Guo has officially joined the ranks of the world’s billionaires, becoming the youngest self-made woman billionaire at the age of 30, overtaking pop superstar Taylor Swift.
As reported by Forbes, the milestone coincides with her former company, Scale AI, preparing to finalize a major tender offer expected to close on June 1. The deal allows early investors and employees to sell their shares and values the artificial intelligence company at an eye-popping $25 billion, up 80% from its $13.8 billion valuation just last May.
Guo co-founded Scale AI in 2016 and has since gone on to launch multiple ventures. Her ascension marks a notable shift in the tech and wealth landscape, placing her ahead of Swift, who had held the title of youngest self-made woman billionaire since late 2023.

Scale AI: The infrastructure powering the AI revolution
Often described as providing the “picks and shovels” of the AI gold rush, Scale AI specializes in data labeling for training artificial intelligence systems. The company’s client list includes major players such as the U.S. government and OpenAI.
Guo’s contributions during Scale AI’s early years helped shape the company’s trajectory into one of the most influential names in the industry. Though she has since exited the company, her equity stake and strategic vision continue to bear fruit.
From middle school coder to Silicon Valley success
Guo’s rise is emblematic of the modern tech dream. The daughter of Chinese immigrants, she grew up in the San Francisco Bay Area and began coding in middle school. She later attended Carnegie Mellon University but left to become a Thiel Fellow—a prestigious program backed by investor Peter Thiel that funds young entrepreneurs.
Before co-founding Scale AI with Alexandr Wang, whom she met while working at Quora, Guo briefly worked at Snapchat. Her experience and connections positioned her for success in the emerging AI space.
Diversifying with new ventures and high-profile investments
After stepping away from Scale AI, Guo launched Backend Capital, a venture capital firm, and has invested in several startups that have since hit billion-dollar valuations, including Ramp.
In 2022, she founded Passes, a subscription-based content platform likened to Patreon and OnlyFans. Passes has drawn notable talent, including gymnast Olivia Dunne, NBA icon Shaquille O’Neal, and DJ Kygo. Over the past three years, the platform has raised $50 million and is currently valued at $150 million.
Legal scrutiny over content moderation
Despite its early success, Passes has come under scrutiny. Last month, a lawsuit alleged the platform had hosted child sexual abuse material (CSAM). A spokesperson for Passes told Forbes that the company “refutes any claims that it approved or condoned the posting of underage explicit content,” and noted that all underage creators had been banned prior to the filing of the lawsuit.
A generational shift in the billionaire landscape
With this achievement, Guo eclipses Taylor Swift, now 35, who had been recognized by Forbes in 2023 as the youngest self-made woman billionaire.
According to Forbes, just over 100 women globally have built fortunes of $1 billion or more through their own efforts. Among the six who are under 40, half are American citizens, signaling a new era of U.S.-driven innovation and wealth creation.
Lucy Guo’s story, from coding in middle school to helming multimillion-dollar ventures, exemplifies the evolving face of entrepreneurship in the digital age.
