Technology consulting company TMC has acquired (embedded) software specialist Sioux Technologies NV, the Belgian entity of high-tech solutions provider Sioux Technologies, headquartered in Eindhoven. Over the past 25 years, the specialist has built a strong reputation and supports customers such as Atlas Copco, Antwerp Space, and Synamedia with complex software challenges. The acquisition strengthens TMC’s software expertise and its position in the Belgian market.
Sioux Belgium is based in Herentals and consists of 33 experts specializing in high-end software development for complex technological applications. Over the coming year, Sioux Belgium will be integrated into TMC Belgium. During this transition period, the team will remain fully on board and the organizations will work more closely together, benefiting customers of both Sioux and TMC.
Emmanuel Mottrie, CEO of TMC Group, says: “Sioux Belgium is a strong fit for TMC, both in terms of company culture and customer portfolio. We are very pleased with the team and with the specific software expertise that Sioux adds to our services. Dutch-speaking experts within this software specialization are scarce, making this team a valuable addition for TMC and for customers in the region.”
According to Filip Eykens, Managing Director of Sioux Belgium, the acquisition creates attractive opportunities: “Joining TMC creates room for further growth and makes it easier to attract new talent. At the same time, we can continue to serve our customers with the same focus and quality. We look forward to this next chapter.”
Since 2025, TMC has accelerated its acquisition strategy. The renewed shareholder structure with Apheon and MML Capital enables TMC, alongside organic growth, to pursue acquisitions more actively, with the ambition of completing four to six acquisitions per year. TMC has already successfully completed several strategic acquisitions in the Netherlands, Germany, and Belgium, including Level21 (2025), Adventec Consulting (2025), Guldberg and Personites (2024), Open Pixel Systems (2024), and Mobilee (2023).
Manufacturing companies are under growing pressure to use raw materials more efficiently, reduce waste and comply with increasingly complex regulations. At the same time, many small and medium sized enterprises (SMEs) struggle with the question: where do we start?
We are proud to announce that we have signed an agreement to acquire engineering and consultancy specialist WEB. This acquisition is a major step for both companies and an important milestone in our international growth.
Last autumn, we strengthened our presence in Sweden through the acquisition of Level21 in Västerås. Today, we take the next step with the opening of a dedicated office in the city, expanding our footprint in one of Sweden’s most technology-intensive regions.
