Investment thesis

Factorial Funds pursues a strategy of concentrated technology investments. The team draws on roughly a decade of experience in machine learning and autonomous vehicles, gained during a period when AI architecture was still emerging and computing resources were limited. That environment required resourcefulness and ingenuity, which shaped the firm's appreciation for founders who build in a similarly scrappy, inventive manner.
