Cuspai

CuspAI is a Cambridge, UK artificial intelligence company, founded in 2024, building generative AI for materials discovery. Its platform lets users specify desired physical and chemical properties — such as selective CO2 binding — and then generates, evaluates, and optimizes candidate molecular and material structures for applications spanning carbon capture, energy storage, catalysis, water purification, electric vehicles, and healthcare. CuspAI has raised roughly $130M (a $30M seed and a $100M Series A in September 2025) from investors including Northzone and Prosus Ventures, and maintains open-source scientific computing tooling on GitHub. As of mid-2026 the company operates a placeholder marketing site with no public API, developer portal, or SDK surface.

Cuspai is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Materials Discovery, Materials Science, and Deep Learning.
