# Sumeet Singh

> Sumeet Singh is the founder and managing partner of Worldbuild, a thesis-driven venture capital firm investing in creative technologists building the post-software era. Previously a partner at Andreessen Horowitz, he led investments in companies like Sardine, Carry1st, and Adaptive. His portfolio includes Brigit (acquired for $500M) and Revolut (valued at $45B). A Georgetown graduate, Singh co-founded The Hilltoss, a student-run restaurant, and Creature/Of, a sustainable streetwear brand. Based in New York, he's known for his disciplined research ritual - spending Friday and Saturday mornings at a Brooklyn cafe, diving deep into AI research papers on his iPad. His investment thesis centers on two winning paths: building infrastructure that enables AI to scale (compute, data, energy, security), or creating entirely new workflows that only AI makes possible.
