About
Guillermo Rauch created Next.js, the framework that powers much of the modern web, and founded Vercel — the 'AI cloud' that deploys it — worth $9.3 billion after its September 2025 Series F led by Accel and GIC. A self-taught programmer from Lanús, Argentina who joined the MooTools core team at 16 and wrote socket.io and Mongoose, he moved to San Francisco as a teenager, co-founded LearnBoost and Cloudup (acquired by Automattic in 2013), and started ZEIT — renamed Vercel — in 2015. He is one of tech's most prolific angels, with 700+ investments including Supabase, Replit, and Perplexity, and Vercel's v0 won a 2025 Webby.
