These Belgian corporate groups and holding companies are primarily large, well-established enterprises, many with a long history and significant international presence. They operate across diverse sectors, including construction, manufacturing, and professional services. BESIX, founded in 1909, is a multidisciplinary construction group, while Samsonite, established in 1910, is a global luggage brand. Bnode specializes in transportation and logistics, and House of HR provides human resources services.
A notable pattern is the concentration of headquarters in and around Brussels and Kortrijk. Other companies like Unilin (building materials), SMT Group (machinery), Yazaki Europe (motor vehicle manufacturing), and Marsh Europe (professional services) also demonstrate the broad industrial scope of these Belgian groups.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
