Jeff Bezos backs CuspAI's $400M raise as AI materials science startup hits $2.6B valuation

CuspAI: Bezos backs $2.6bn materials-AI startup

CuspAI, which uses AI to design new materials, is reportedly raising $400M led by Bezos's family office, days after he launched his own physical-AI lab. The bet: the next AI gold rush is in atoms, not text. Jeff Bezos appears to have settled on his AI thesis, and it is not chatbots. It is the physical world. CuspAI, a two-year-old Cambridge startup that uses AI to design new materials, is in talks to raise about $400mn at a $2.6bn valuation, the Financial Times reports. The round is led by Bezos Expeditions, the Amazon founder's family office, alongside Kleiner Perkins. Term sheets have been signed, but the deal has not closed, and CuspAI declined to comment. If it lands, it would more than quadruple the company's $520mn valuation from September, a 5x jump in nine months. A 'search engine for the material world' CuspAI was founded in 2024 by Chad Edwards, a chemist who helped build quantum-computing firm Quantinuum, and Max Welling, a machine-learning pioneer who was a distinguished scientist at Microsoft Research. Its advisory board includes two of AI's most decorated names, Geoffrey Hinton and Yann LeCun. The pitch is a "search engine for the material world": describe the properties you need, such as strength, conductivity or heat tolerance, and the system proposes chemical compositions up to 10 times faster than conventional methods. The differentiator is that its models are "synthesis-aware", meaning the materials they suggest can actually be manufactured rather than just simulated. Meta is already using it for carbon capture, Hyundai for clean energy and Kemira to strip PFAS "forever chemicals" from water. The Bezos pattern The timing is the tell. Just six days earlier, Bezos unveiled Prometheus, a roughly $41bn physical-AI lab built to do for engineering what large language models did for text, his first chief-executive role since leaving Amazon. CuspAI fits that worldview precisely, sitting where generative AI meets the physical world. Bezos Expeditions has spread smaller bets across Anthropic, Perplexity and Figure AI, but materials science is the part of AI he now seems most convinced about. A crowded, unproven frontier He is not alone. XtalPi is valued at about $2.5bn, Periodic Labs (founded by ex-OpenAI and DeepMind staff) raised a $200mn seed at a $1bn valuation, and European rivals Altrove and Dunia Innovations are chasing the same prize. The caveats are real. The round is not closed, the valuation is a steep mark-up for a roughly 65-person lab, and AI-designed materials are still an early commercial bet rather than a proven business. But two nine-figure Bezos moves into physical AI inside a week is a loud signal about where one of tech's sharpest operators thinks the next decade of value sits, and it is landing in the UK.

Scientific research start-up CuspAI to raise $400m with Jeff Bezos among backers - FT

UK start-up CuspAI is set to raise $400m in a funding round that includes Amazon's Jeff Bezos, according to the Financial Times. When Turing Prize laurate Yann LeCun joined Nobel Laureate and Turing Prize winner Professor Geoffrey Hinton on CuspAI's Advisory Board last year, the young materials science and AI start-up's reputation as a 'soonicorn' only grew. Now the Financial Times is reporting that the two-year old Cambridge-based start-up CuspAI has raised financing of $400m, which would quadruple its valuation to some $2.6bn, with Amazon's Jeff Bezos among its backers. CuspAI had been valued at just $520m in September of last year, so that is a significant jump for the company that applies generative AI to materials science research. The FT cites sources who say investors in this round include Silicon Valley venture capitalists Kleiner Perkins and Bezos Expeditions, the Amazon founder's family office. It says term sheets have been signed but that the deal is not yet closed. Founded by Max Welling - a professor of machine learning at the University of Amsterdam and a pioneer of AI's application to science - and serial founder Dr Chad Edwards, CuspAI got a shout out from Nvidia's Jensen Huang as one of the UK start-ups to watch when he met with UK Prime Minister Kier Starmer last year. And indeed Nvidia's venture arm was among the backers in its Series A funding round of over $200m last year. The round was co-led by US fund New Enterprise Associates (NEA) and Temasek, with participation from NVentures (NVIDIA's venture capital arm), Samsung Ventures, Hyundai Motor Group, and returning investors and angels. CuspAI's angel backers also form a bit of a 'who's who' list, boasting Durk Kingma, OpenAI co-founder, Zoubin Ghahramani, Google VP of Research, Arash Ferdowsi, co-founder of Dropbox, and Thomas Wolf, founder of Hugging Face - among others. Founded in 2024, CuspAI describes itself as "a frontier AI company that specialises in using generative AI and molecular simulation to accelerate the discovery of breakthrough materials for industrial applications across semiconductors, energy, and climate". It is one of several players looking to lead in this space, and it is little surprise that it caught the eye of Bezos, who himself is leading his own physical AI venture Prometheus, which raised some $10bn in April.
