Bezos Backs UK AI for Material Discovery
20 Jul
Summary
- AI startup CuspAI received $450 million in funding.
- The company aims to find new materials for chipmakers.
- It seeks to reduce reliance on rare metals.

A British artificial intelligence startup, CuspAI, has successfully raised $450 million in a Series B funding round, reaching a valuation of $2.6 billion. Investors include Amazon founder Jeff Bezos and the UK government's sovereign AI fund. The company's mission is to act as a "search engine for rare materials," accelerating technological breakthroughs.
CuspAI has launched the AI Materials Foundry, a coalition of over 48 tech and industrial firms. This initiative aims to develop AI-powered software to discover new materials essential for chipmakers and other industries. The ultimate goal is to drastically cut research timelines and minimize or eliminate the use of critical rare metals like iridium and ruthenium in supply chains.
This funding will support CuspAI's international expansion, including a new office in Singapore and increased staff in existing locations like Cambridge, Amsterdam, Berlin, Tokyo, and the US. The company's efforts are focused on enabling industrial progress by discovering materials that do not yet exist, addressing a critical bottleneck for future technological advancements. CuspAI's work is crucial for innovations in energy, batteries, and semiconductors.
