davidsenra recounts the founder pipeline from Alexandr Wang's 19th birthday party: HRT interns who went on to found Hyperliquid (Jeff Yan, $20B), Cognition (Scott Wu, $48B), and Decagon (Jesse Zhang, $4.5B) — plus Wang himself, who built Scale AI and sold 49% to Meta for $14.3B.
Wang recalls interning at trading firm HRT with 12 Harvard/MIT students, and recently telling HRT's founder: "Just invest into the interns! All the interns get seed checks!"
