Bezos and UK gov back CuspAI's $450M bid to be 'search engine for rare materials'
A 2-year-old startup wants to end chipmakers' dependence on rare metals using frontier AI.
CuspAI, a two-year-old Cambridge-based startup, raised $450M in Series B funding led by Jeff Bezos and the UK government's sovereign AI fund, valuing the company at $2.6B. The round also included Kleiner Perkins and follows a $100M Series A last year. CuspAI aims to become a 'search engine for rare materials' by using frontier agentic AI to discover new compounds that could replace scarce metals like iridium and ruthenium in chipmaking and energy storage.
The company launched the AI Materials Foundry, a coalition of 48 tech, industrial, and research entities including Nvidia, Meta, Hyundai, and Lam Research. CuspAI's co-founders, Dr. Chad Edwards and Prof. Max Welling, say the world's next industrial leaps are constrained by materials that don't yet exist. The funding will fuel international expansion to Singapore, Amsterdam, Berlin, Tokyo, and the US. Apple and Google veteran John Giannandrea is helping set up US operations, while AMD board member Abhi Talwalkar advises on chip partnerships.
- CuspAI raised $450M in Series B funding, valuing the startup at $2.6B, with participation from Jeff Bezos and the UK government's sovereign AI fund.
- The AI Materials Foundry coalition includes 48+ members such as Nvidia, Meta, and Hyundai to accelerate materials discovery for semiconductors and energy.
- CuspAI's AI aims to cut research times and reduce reliance on rare metals like iridium and ruthenium in chipmaker supply chains.
Why It Matters
CuspAI's AI-driven materials search could unlock cheaper semiconductors, better batteries, and cleaner energy, solving a critical bottleneck in tech progress.
