Is it really over for Taylor Swift? Has the music queen lost her status as the youngest self-made billionaire woman? Well, as per Forbes, this is true, as recently a 30-year-old serial entrepreneur, Lucy Guo, has crossed the pop icon Taylor Swift's youngest billionaire rank.
This milestone aligns with a significant financial advancement for her former startup, Scale AI, which is approaching a tender offer scheduled for June 1. The deal, valuing the AI data annotation firm at $25 billion, is an 80 per cent jump from its $13.8 billion valuation last May.

The clients of Scale AI include the US government and OpenAI. Guo is a first-generation Chinese-American from the Bay Area who taught herself to code in middle school.
She also briefly attended Carnegie Mellon University and then left to join the Thiel Fellowship, a $100,000 grant programme for young entrepreneurs founded by Peter Thiel, famously known as Donald Trump's man in Silicon Valley.

After this, when she left Scale, she launched Backend Capital, a venture capital company, and invested in some startups like Ramp, which is now valued in the billions.
Guo, as mentioned, also joined the Thiel Fellowship that provides $100,000 and mentorship to young innovators. Interestingly, Thiel's venture fund, Founders Fund, was also an early investor in various companies of Elon Musk, including space cargo and brain-chip startup Neuralink.
