Value proposition

Reduces materials R&D timelines from years to days by solving the 'process-structure-performance' conundrum, allowing manufacturers to optimize material recipes for maximum efficiency and lower costs.

Products and solutions

["Generative AI Materials Design Platform","Microstructural Optimization Engine","Process-Structure-Performance (PSP) Digital Twin","Battery Chemistry Simulation & Discovery Suite"]

Unique value

Focuses specifically on the microstructural level of materials, using generative AI to perform 'inverse design'—starting with desired performance metrics and automatically generating the required manufacturing parameters.

Target customer

Battery manufacturers, Electric Vehicle (EV) OEMs, chemical companies, and advanced materials R&D laboratories.

Industries served

["Energy Storage & Batteries","Automotive (Electric Vehicles)","Materials Science","Clean Technology","Chemical Manufacturing"]

Technology advantage

Proprietary generative models that bridge the gap between experimental lab data and industrial manufacturing, significantly reducing the reliance on slow, expensive trial-and-error physical testing.

How they differentiate

Focuses on the 'process-structure-performance' (PSP) conundrum using generative AI to perform inverse design at the microstructural level, rather than just chemical informatics.

Main competitors

["Citrine Informatics","Uncountable","Aionics","Noble.AI"]

Key partnerships

["Imperial College London (Academic Spin-out)","The Faraday Institution (Battery Research)","Henry Royce Institute (Materials Science)","UK Government (Manchester Prize for AI)","Investors: Speedinvest and Racine2 (Serena & Makesense)"]

Notable customers

["The Faraday Institution","Henry Royce Institute","Confidential Battery OEMs"]

Major milestones

["Spun out from Imperial College London in 2023","Won the £1 Million Manchester Prize for AI for Public Good in January 2025","Closed $8M Seed Round in February 2026 to scale commercial deployment"]

Growth metrics

Winner of the £1M Manchester Prize; scaled from an Imperial College London spin-out to a venture-backed commercial entity within 2 years.

Market positioning

Deep-tech AI 'intelligence layer' for advanced materials and battery manufacturing.

Geographic focus

United Kingdom, Europe, and North America

Patents and IP

Proprietary algorithms and IP spun out from Imperial College London; specific public patent filings not disclosed in current funding announcements.
