Cambridge-based CuspAI announced a $450 million Series B on July 20, 2026, co-led by Kleiner Perkins and NEA, with 'significant participation' from Jeff Bezos' Bezos Expeditions. The round values the two-year-old startup at $2.6 billion, roughly a five-fold jump from its September 2025 Series A round that valued it at $520M, and lifts total funding above $670M.
An 'AI Materials Foundry' with 45+ partners
Alongside the raise, CuspAI unveiled the AI Materials Foundry, described by co-founders Chad Edwards and Max Welling as 'a global network of data, labs, compute and scientific expertise for the design of new materials.' Founding partners include NVIDIA, Meta, Samsung and Hyundai Motor Group alongside Henkel, Applied Materials, Tokyo Electron and Lam Research - the roster targets the exact tool chain that determines whether a novel material can be scaled from a lab to a fab.
Investors are stacking bets on physical AI's chemistry layer
New investors joining the round include Glade Brook Capital Partners, Lux Capital, AMD Ventures, Tru Arrow Partners, StepStone, the UK government-backed Sovereign AI Venture Fund, the Netherlands' Invest-NL and John Doerr; existing investors Temasek, Basis Set Ventures, Giant Ventures, Touring Capital, Prosus, Phoenix Court and Northzone all followed on. Kleiner Perkins partner Josh Coyne argued that CuspAI's edge is designing 'materials that can actually be built, not just ones a model can dream up' - a critique of prior AI-for-science efforts that struggled to bridge silicon and fab.
What the money buys
CuspAI plans to expand across the US, APAC and Europe and to scale the Materials Foundry. It has already opened a Singapore office and staffed hubs in Cambridge (Edwards), Amsterdam (Welling), Berlin, Tokyo and the US. Advisers include Yann LeCun, Geoffrey Hinton and former Apple/Google AI chief John Giannandrea, who is helping stand up US foundry operations. Applications range from stripping forever-chemicals from drinking water to designing next-generation chip materials, with early customers including ASML and Meta.
Why this round matters
The financing lands as physical-AI plays draw record capital, from NEURA Robotics' $1.4B Series C to Broadcom's $35B AI XPV platform and Williams' behind-the-meter power for AI. Backing CuspAI is a bet that the next constraint on progress isn't compute - it is which molecules and lattices exist to be built.
