DDM Company is a Belgian family office. We back engineering companies — power electronics, climate technology, industrial software.
We take minority positions in companies building physical and industrial technology: power conversion, electrification, climate infrastructure, and the software that runs it.
We are small by design. Simple decision-making, no committee, no third-party capital. We work with the companies we back.
| Company | What it is | Why we are in it |
|---|---|---|
| AixControl | Power electronics — development through series production, control systems, real-time simulators, end-of-line test equipment. | An RWTH Aachen spin-off that turns laboratory power electronics into shippable hardware. The thesis in one company. |
| ClimateCamp | Collaboration platform for supply-chain carbon data and CSRD reporting. | Carbon accounting only works if suppliers take part. ClimateCamp builds for the network, not for the report. |
| Ambrio | Immersive sound systems for live music. | Spatial audio has been a studio format for decades. Ambrio is making it work in a field, at scale. |
Private equity in established Belgian companies.
We invest family capital, so we do not work to a vintage year. But every position has to earn its place, and we sell when the thesis is done rather than when a fund's clock runs out.
Diligence starts with whether the technology works, and ends with whether the cap table is honest.
DDM was built on a career in academic research. We stay close to the institutions our companies come out of.
