Jeff Bezos Backs CuspAI in $450M Series B Valuation Jump
Cambridge-based startup CuspAI has raised $450 million in a Series B funding round, valuing the company at $2.6 billion. The round was co-led by Kleiner Perkins and NEA, with participation from Bezos Expeditions, the UK's Sovereign AI Fund, and existing investors such as Temasek and Northzone. CuspAI utilizes AI technology to discover and design new physical materials for clean energy, carbon capture, and the semiconductor industry. Operating similarly to a search engine, the platform serves major clients including ASML and Meta. The newly raised capital will fund global expansion and power CuspAI's 'AI Materials Foundry'—a collaborative network designed to accelerate materials research alongside founding partners Nvidia, Meta, Samsung, and Hyundai.
