What Diabatix does
Diabatix is a Belgian software company, founded in 2016 and headquartered in Heverlee (Leuven), that builds ColdStream — a cloud-based, browser-accessible generative design platform purpose-built for thermal management and cooling engineering. The product combines proprietary topology optimization, generative design exploration across heat-sink topologies (pins, fins, gyroids), 1D thermal network approximation, and 3D computational fluid dynamics (CFD) simulation in a single workflow, and is exposed to customers through a public Python API and bi-directional CAD/CAE integrations with ANSYS Fluent, OpenFOAM, nTop, Autodesk Inventor, Synera, and others. Diabatix supports multiple downstream manufacturing methods, including additive manufacturing, die casting, CNC milling, and sheet metal forming, and is ISO 27001, GDPR, and NIS2 compliant.
The company was originally a thermal-engineering consultancy and pivoted in 2021 to a software-as-a-service model with the launch of ColdStream. Revenue is generated via annual subscription (quote-based, not publicly disclosed) with a free viewer tier; go-to-market combines direct enterprise field sales, a self-serve trial, and a growing regional channel-partner network covering Europe (Alpha Numerics, Megaflow, Cybernet Systems, Insumma, Jetsoft, Xitadel, Shire Technik) and South Korea (UIT Solutions). Named enterprise customers span semiconductors and high-performance computing (ASML), aerospace (Airbus, Leonardo, NLR), automotive (Magna, GLM), consumer electronics (Dell, Panasonic), additive manufacturing (3D Systems), LED lighting (Avient, Celera Fibras), battery cooling (Amnovis), and research (CERN, KU Leuven). The company participates in the EU-funded IMPACTA (H2020) two-phase cooling consortium and the Flemish SingleOilCnL (VLAIO ICON) motor-cooling project, providing research credibility and channel into aerospace and automotive OEM engineering teams.

Diabatix product offering
Product offeringCore offering
Diabatix develops and sells ColdStream, a cloud-based generative design platform for thermal management. The software automatically generates, optimizes, and validates cooling designs (heat sinks, cold plates, etc.) using topology optimization, 1D thermal network analysis, and 3D CFD simulation in a browser-based workflow. It targets engineering teams in automotive, high-performance computing, consumer electronics, LED lighting, and aerospace.
Product overview
Diabatix offers a single unified product, ColdStream, which is a cloud-based in-browser generative design platform for thermal management. ColdStream is built around several integrated sub-modules: (1) Heatsink Selection for concept generation exploring hundreds of design options, (2) Topology Optimization for detailed design refinement using proprietary algorithms, (3) Thermal Network Approximation for rapid 1D thermal analysis, and (4) 3D CFD thermal analysis for detailed simulation and validation. These capabilities are unified within a single platform that requires no installation and is accessible through regional login portals (EU, US, Asia). The platform supports multiple manufacturing methods including 3D printing, die casting, CNC milling, and sheet metal forming, and integrates with external tools including ANSYS Fluent, OpenFOAM, nTop, Autodesk Inventor, and others. Diabatix was originally a consultancy firm and transitioned to a software provider with the 2021 launch of ColdStream.

Diabatix competitors and assessment
Company assessmentDirect peers
- nTopology (nTop): nTopology is a computational design platform focused on generative engineering for additive manufacturing. It is both a direct competitor in generative design workflows and a technology integration partner of Diabatix, with overlapping use cases in performance-driven, manufacturing-aware geometry optimization.
- COMSOL: COMSOL Multiphysics is a simulation platform widely used for thermal, fluid, and multiphysics engineering analysis. It competes directly with ColdStream for thermal engineer mindshare in research, academic, and advanced industrial settings, and shares a similar SaaS-like licensing model.
- SimScale: SimScale is a cloud-native CAE platform offering CFD, thermal, and FEA simulations via a browser. It overlaps directly with ColdStream on cloud-based, no-installation thermal simulation and competes for the same enterprise engineering audiences.
- 6SigmaET (Future Facilities): 6SigmaET by Future Facilities is a dedicated electronic thermal management simulation tool widely used in data centers and electronics. It competes more narrowly than the broad CAE suites but directly addresses thermal engineer workflows that ColdStream also targets.
Broad incumbents
- ANSYS: ANSYS is a leading CAE/CFD platform whose Fluent and Icepak products dominate thermal and fluid simulation in the same customer set Diabatix serves. ANSYS is simultaneously a technology integration partner (export to Fluent) and the most credible broad incumbent competitor that could absorb generative thermal design into its suite.
- Siemens Simcenter: Siemens Simcenter (including FloTHERM/Flotherm XT for electronic thermal management) is a long-standing incumbent in thermal simulation for electronics, automotive, and aerospace. It competes with ColdStream across Diabatix's primary verticals and offers a much broader multiphysics portfolio.
- Dassault Systèmes SIMULIA: Dassault Systèmes' SIMULIA portfolio (Abaqus, CST, PowerFLOW) provides simulation tools that overlap with thermal and CFD analysis. It competes at the platform level across the same automotive, aerospace, and HPC accounts that Diabatix targets.
- Autodesk (Fusion 360 / generative design): Autodesk's Fusion 360 and generative design tools target mechanical engineers with cloud-based CAD and optimization features. It is simultaneously an integration partner (Autodesk Inventor) and a broad incumbent that could expand native generative thermal capabilities.
- Altair (Inspire / OptiStruct): Altair's Inspire and OptiStruct products are well-known topology optimization and generative design tools, frequently used in lightweighting and additive workflows. It competes for engineering seats and partner channel attention across overlapping automotive and industrial customers.
Emerging players
- Rescale: Rescale is a cloud HPC platform that runs third-party CAE solvers in the cloud, including CFD/thermal workloads. It is an adjacent infrastructure layer to ColdStream's cloud-delivered simulation approach and competes indirectly for cloud-based engineering simulation budgets.
