Lucy Guo is a Chinese-American computer engineer, entrepreneur, and venture investor who has a net worth of $1.3 billion. Lucy Guo earned her fortune from Scale AI, a data annotation startup she co-founded in 2016. Though she was fired from the company just two years later, she held on to her equity stake, which is now worth nearly $1.2 billion. In 2025, following a secondary tender offer that valued Scale AI at $25 billion, Guo became the youngest self-made female billionaire, surpassingTaylor Swiftfor the title.

After leaving Carnegie Mellon, Guo interned at Facebook and later joined Quora as a product designer, where she met Scale AI co-founderAlexandr Wang. She later became the first female product designer at Snapchat, where she helped develop the Snap Maps feature. In 2016, she and Wang decided to start their own company.

Lucy Guo was born on October 14, 1994, in Fremont, California, to Chinese immigrant parents who were both electrical engineers. From an early age, she showed entrepreneurial ambition, teaching herself how to code, selling Pokémon cards at school, and creating bots to farm and sell assets in the online game Neopets. She studied computer science and human-computer interaction at Carnegie Mellon University but dropped out during her senior year after receiving a $100,000ThielFellowship, a grant awarded to students who leave school to pursue startups full-time.

Guo and Wang co-founded Scale AI in 2016 to provide labeled data for training artificial intelligence models. The company initially focused on data for self-driving cars, paying contract workers to tag images and text. Major clients eventually included OpenAI, Meta, and the U.S. government, which used Scale's software to analyze satellite images during the war in Ukraine. Scale also created Remotasks, an internal outsourcing agency for data labeling, which has been criticized for low pay and poor working conditions in Southeast Asia and Africa.

In 2018, Guo was fired from Scale following disagreements over company direction, though she publicly stated she was proud of what the company had accomplished. Despite her departure, she retained an estimated stake of just under 5%, which became massively valuable after a 2025 tender offer valued the company at $25 billion. At the $25 billion valuation, Lucy's 5% stake became worth $1.25 billion on paper.

She has since founded and run multiple ventures, including the creator platform Passes and the venture fund Backend Capital. Guo is one of just six self-made women billionaires under 40 and the only one who built her fortune from a company she no longer works for.
