Diabatix

The firm's initial business model was based on consultancy, providing thermal engineering expertise on an hourly basis. This approach allowed the team to gain direct insight into industry challenges. Recognizing the limitations of a time-based model for ambitious growth, Diabatix transitioned to a project-based engineering service, selling solutions rather than hours. In parallel, the company was developing its proprietary generative design software. Following repeated customer requests for direct access, Diabatix launched its ColdStream platform in 2021, pivoting to a Software-as-a-Service (SaaS) business model. This strategic shift was supported by a €2 million early VC funding round from Saffelberg Investments in January 2022.

Diabatix's core offering, ColdStream, is a cloud-native platform that automates and optimizes the design of cooling components like heat sinks and cold plates. The software leverages a combination of artificial intelligence, generative design, and topology optimization to create designs from scratch, aiming to maximize heat transfer and efficiency. It serves engineers across demanding sectors such as automotive, aerospace, high-performance computing, consumer electronics, and semiconductor manufacturing. ColdStream is designed to be accessible to engineers at all experience levels, requiring no special hardware or software installation. The platform integrates with industry-standard tools like Ansys Fluent and OpenFOAM, streamlining the design and analysis workflow. Key features include automated generation of complex channel designs, topology optimization, and analysis of temperature distribution, fluid dynamics, and thermal resistance. The platform supports various manufacturing methods, from 3D printing to traditional techniques like die casting and skiving, ensuring designs are manufacturable.
