Sumeet Singh founded Worldbuild after roles as an investor at Andreessen Horowitz and in operating and investing positions at Brigit and Nyca Partners, building the firm around the idea that the best early bets require genuine intellectual conviction rather than pattern-matching against what other investors are already doing. Worldbuild closed a $30 million debut fund in 2026, backing early-stage companies across AI infrastructure, developer tools, aerospace, and energy, including SF Compute and Browserbase - bets Singh has said he was able to make early precisely because his thesis-driven approach let him form a point of view before a company looked obvious to generalist investors.
No public exit yet - Worldbuild closed its debut fund in 2026 and is still building its earliest cohort, including SF Compute and Browserbase
