Despite leaving years ago, Scale AI’s 30-year-old cofounder has become the youngest self-made woman billionaire in the world by holding onto her stake in the company.
Scale AI, a prominent artificial intelligence company, is finalizing a tender offer allowing early employees and investors to sell shares to new or returning backers. The deal, expected to close by June 1 barring unforeseen events, pegs the company’s valuation at $25 billion—a sharp 80% jump from its $13.8 billion valuation in May 2023, sources confirmed.
The new valuation propels 30-year-old cofounder Lucy Guo to the top of Forbes’ list as the world’s youngest self-made woman billionaire, surpassing 35-year-old pop star Taylor Swift. Guo retains nearly a 5% stake in Scale AI, estimated at $1.2 billion, with her total net worth reaching $1.25 billion. “I don’t really think about it much, it’s a bit wild. Too bad it’s all on paper haha,” she said via text.
Guo cofounded Scale AI in 2016 with Alexandr Wang but was reportedly fired in 2018. “We had a difference of opinion but I am proud of what Scale AI has accomplished,” she stated.
Following her exit, Guo launched Passes, a creator platform now valued at $150 million. Despite recent legal controversy, a company spokesperson said any allegations are “baseless.” Guo continues to build her ventures while balancing intense workouts and a vibrant social life.
