Sumeet Singh, formerly a Partner at Andreessen Horowitz (2021–2024), invests primarily in early-stage fintech, consumer social, marketplaces, commerce, and healthcare, with a typical check size ranging from $500K to $40M and a sweet spot at $20M. His notable portfolio includes fintech company Brigit (where he previously worked in operations) and AI infrastructure firm Browserbase, for which he is a founding investor. After leaving a16z, Singh launched his own thesis-driven firm, Worldbuild, focusing on the "post-software era" by backing companies that either enhance model capabilities or create entirely new AI-enabled workflows rather than building specialized SaaS tools.
