ToffeeX is a London-based engineering software company redefining how high-performance thermo-fluid components are designed. Founded in 2020 as a spin-out from the Department of Aeronautics at Imperial College London, the company develops physics-driven generative design software that enables engineers to design, simulate, and optimise complex multiphysics components such as heat exchangers within a unified workflow.
Our flagship product is a fully managed, cloud-native SaaS platform which integrates seamlessly into existing CAD and CAE environments. The software combines advanced multiphysics simulation with generative design algorithms such as topology optimisation, allowing engineers to explore a significantly wider design space while maintaining control over engineering intent and manufacturing considerations.
ToffeeX primarily serves customers in the aerospace, energy, and automotive sectors, working with global industry leaders including Airbus, Rolls-Royce, and Toyota. Components designed using ToffeeX are operating in real-world production environments, from natural gas processing facilities to high-pressure die casting production lines.
Built around the principle that engineering tools should reflect real physics and real manufacturing constraints, ToffeeX emphasizes explainability, transparency, and measurable performance. Its engineer first culture prioritizes production-ready results and defensible engineering outcomes over visual concepts or theoretical studies.
With a growing team of approximately 25 employees, ToffeeX is advancing a new standard in engineering design and optimisation, helping organizations accelerate innovation while maintaining technical rigour and manufacturing alignment.
