CuspAI

Cambridge-based frontier AI company building an AI-powered "search engine for materials" that uses generative AI and molecular simulations to discover and validate new materials in months instead of decades. Founded by AI pioneer Max Welling and chemist Chad Edwards, with Geoffrey Hinton and Yann LeCun as advisors, CuspAI partners with Hyundai, Meta, and Kemira on applications from carbon capture to PFAS removal. In July 2026 the company raised a $450 million Series B at a $2.6 billion valuation, co-led by Kleiner Perkins and NEA with participation from Jeff Bezos' Bezos Expeditions, Lux Capital, and AMD Ventures, bringing total funding to about $670 million.
