Early life and education
Guo was raised in Pleasanton, 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
After leaving Carnegie Mellon, 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] When Meta bought Scale AI for $25 billion in May 2025, Guo became the world's youngest self-made female billionaire, displacing Taylor Swift from the position.[12][13][14] In late 2025, the title passed to Luana Lopes Lara, co-founder of Kalshi.[15] Guo was one of only six self-made female billionaires to reach the milestone before age 40 as of 2025, according to Forbes.[16][17]
In 2018, Guo launched an app called Apply to Date allowing users to create a dating resume.[18]
In 2022, Guo founded Passes, an OnlyFans competitor.[19][20][2] As a Miami party girl, she used her connections with Miami-based entertainment agencies to launch the company.[19] It raised a $40 million Series A in 2024.[21] Passes acquired other creator platforms, including Fanhouse, founded by Rosie Nguyen.[22]
Passes was reported in 2024 to have allowed an account featuring a 12-year-old selling bikini photos after she had been banned by another platform. The account was removed only after the New York Times requested comment.[23] In 2025, Passes and Guo were sued by another creator who stated that they had distributed sexually abusive material of her when she was a child.[24][25][26] Guo's Passes platform claims that it does not allow nudity or sexual content and said the claim was "defamatory".[27]
In 2019, she launched Backend Capital,[28] originally called Backend Ventures,[29] a venture capital firm that primarily funded early-stage engineering startups.[30]
Personal life
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.[31][32] She was described by the New York Post in 2022 as Miami's number one party girl.[11]
As of 2024, she was residing in Los Angeles after purchasing another home in West Hollywood for $4.2 million.[33][34][35][36]
In 2026, she released a tech house track, Champagne On Me.[37]
