ToffeeX

3D Printing·Series A

ToffeeX is a London-based physics-driven generative design software company founded in 2019 by three Imperial College London researchers: Audrey Gaymann, Marco Pietropaoli (CEO), and Francesco Montomoli. The platform uses advanced physics simulations to automatically optimise complex thermal fluid components such as cold plates, heat exchangers, and heat sinks in hours rather than weeks, supporting additive manufacturing, machining, stamping, and chemical etching. ToffeeX has established traction with clients including Airbus, Rolls-Royce, EOS, Ricoh, GE, Toyota, Baker Hughes, Westinghouse, and the Fraunhofer Institute. The company raised £1M in seed funding from IQ Capital in 2020, followed by a £5M Series A in 2022 led by Presidio Ventures.
