Lucy Guo is an American social media influencer and engineer who co-founded Scale AI.[1] In 2022, she founded her second start-up, known as Passes.[2] As of 2025, Guo is the world's youngest female self-made billionaire, due to her stake in Scale AI.[3][4][5]

Early life and education

[edit]

Guo was raised in Fremont, California, by Chinese immigrant parents who worked as electrical engineers. She began coding at a young age; as a teenager she taught herself programming and earned money by developing bots for the online game Neopets and selling the in-game assets for profit.[6] Guo enrolled at Carnegie Mellon University where she studied computer science[6] but dropped out in 2014 after being selected for the Thiel Fellowship,[7][8] a two-year $100,000 grant for young people to pursue entrepreneurial projects instead of completing their studies.[6]

Career

[edit]

After dropping out of Carnegie Mellon to pursue a Thiel Fellowship, Guo interned at Facebook before joining Snapchat as the company's first female designer.[9] At Snapchat, she helped develop Snap Maps.[10] She then moved to Quora where she met Alexandr Wang.[11] They co-founded Scale AI in 2016, but she was fired two years later in 2018.[1] The 5% stake she held in the company led her to become the youngest self-made female billionaire in May 2025, replacing Taylor Swift.[12]

In 2018, Guo launched an app called Apply to Date allowing users to create a dating resume.[13] In 2019, she launched Backend Capital,[14] originally called Backend Ventures,[15] a venture capital firm that primarily funds early-stage engineering startups.[16] The firm has funded startups such as the fintech company Ramp.[15][16]

In 2022, Guo founded Passes, a social platform that allows creators to post content for paid subscribers.[17] It raised a $40 million Series A in 2024.[18]

Guo's Passes platform does not allow nudity or sexual content, and takes a ten percent margin from creator earnings.[19] In February 2025, Passes and Guo were sued by a creator who claimed Passes hosted and distributed nude photos of her in the month before her 18th birthday.[2][20][21]

Personal life

[edit]

As of 2024, Guo lives in Los Angeles.[22][23][24]

She was "living as a digital nomad" for a number of years before buying a $6.7 million apartment in 2020 in Miami where her parties caused conflict with neighbors.[25][26]

In 2024, she purchased another $4.2 million home in West Hollywood,[27] and then purchased a $30 million home in Hollywood Hills in 2025.[28]
