Overview
Founded in 2016 in Leuven, Diabatix applies generative design AI to the thermal engineering domain. The traditional approach to heat sink design required engineers to manually iterate through geometries and validate each option, a process measured in days or weeks. Diabatix's ColdStream platform generates and validates optimized designs in a fraction of the time, and can output novel topology-optimized structures suitable for 3D printing or CNC machining alongside conventional geometries.
The company initially operated as a professional services firm using its own AI-generated designs for clients. In 2021, after repeated customer demand for direct software access, Diabatix launched ColdStream as a SaaS product. Customers generated over 150,000 designs on the platform in 2024, indicating strong adoption among electronics manufacturers, automotive companies, battery makers, and industrial engineers across three continents.
Diabatix has a technology partnership with Ansys, a major simulation software company, expanding the ColdStream workflow into established engineering environments. The company raised EUR 2M from Saffelberg Investments in 2024 and was recognized in the Deloitte Technology Fast50 2024 with 334% growth.
