    Chapter One is an early-stage venture fund building the new internet, backed by Sequoia, Marc Andreessen, Chris Dixon, Bessemer, Lightspeed, Cendana, and Kleiner Perkins. We invest between $500K - $1.5M in innovative founders at the pre-seed and seed stage. I am particularly interested in data, AI/ML applications, AI/ML infrastructure, developer tools, open-source, and deep tech.
