Daniel Gross.

Daniel Gross is the Co-Founder of AI Grant (alongside Nat Friedman), a program providing funding to early-stage AI companies, and one of the most prolific angel investors in artificial intelligence.

Gross co-founded Cue, a search technology startup, at age 17 while still in high school. Apple acquired Cue for $40 million in 2013, and Gross joined Apple where he worked on Siri's machine learning capabilities. He later became the youngest partner in Y Combinator's history and led YC's AI program. Since leaving YC, Gross has become one of the most active and respected early-stage investors in AI, backing companies across language models, developer tools, healthcare AI, and robotics. AI Grant, which he co-runs with Nat Friedman, provides $250,000 grants to promising AI projects, operating with minimal bureaucracy and maximum speed. Gross's combination of entrepreneurial experience (founding a company as a teenager), large-company AI leadership (Apple/Siri), accelerator expertise (Y Combinator), and prolific angel investing makes him one of the most comprehensively connected figures in the AI ecosystem. His investment portfolio includes many of the companies shaping the current AI landscape.
