Sorry Taylor Swift! Travis Kelce’s GF loses youngest self-made billionaire crown to AI prodigy Lucy Guo and it’s not even close. At just 30, Guo has officially overtaken Swift as the youngest self-made woman billionaire, according to Forbes.
A college dropout, a former Thiel Fellow, and the cofounder of Scale AI, Lucy’s now one of only six women under 40 on the planet to hit that billion-dollar status without family wealth. Her current net worth? A cool $1.3 billion. And the wildest part? She made most of that from a company she got fired from back in 2016.

While Swift was making history on stage, Guo was quietly stacking her empire: coding, designing, investing, and launching startups like Passes, a fan platform that's part of her latest entrepreneurial chapter.
Taylor Swift made headlines in 2023 as the youngest self-made woman billionaire. But that title now belongs to Lucy Guo (per Forbes), the tech genius who helped build Scale AI. While Swift did it through music and tours, Guo coded her way to the top—and she’s not slowing down.
Guo dropped out of Carnegie Mellon, joined the Thiel Fellowship, and jumped straight into the tech world. She worked at Quora and Snapchat before cofounding Scale AI with Alexandr Wang. At just 21, she was leading product design and operations—until the two clashed, and Guo was reportedly pushed out.
Even after her exit, Lucy kept a 5% stake in Scale AI, now worth nearly $1.2 billion. With her second company, Passes, she’s kept that momentum going. According to Forbes, her total net worth now stands at $1.3 billion. Her reaction?
“I don't really think about it much, it's a bit wild. Too bad it's all on paper haha.”
Guo’s in rare company. Only six self-made women under 40 have cracked the billion-dollar mark. And she’s the only one who got there thanks to a company she no longer works for. From fired cofounder to billionaire tech mogul, Lucy Guo is living proof that success doesn’t have to follow anyone else’s script.
