For much of his life, Zain Javaid, 19, wanted to be a quant who uses math and data to guide his investment decisions. And for a while, he was one. But he got bored. Then, in 2022, ChatGPT was released, and he told TechCrunch, “I felt fundamentally excited in a way that I never had been before.”

He became interested in personal AI, and that interest led him to start Ghost, which announced Monday that it has emerged from stealth after a year of building, along with an $11 million seed round led by Andreessen Horowitz. Other investors in the round include Abstract, Audacious Ventures, SV Angel, and Nova. His founding team includes Nicholas Chua, 19, Yifei Chen, 24, and Gautam Sharda, 23.
