These Brussels-based companies primarily operate in the human resources, staffing, and civic and social organization sectors. The list includes a mix of very large public sector entities and substantial private firms, indicating a well-developed ecosystem for employment and social support services. Most companies are well-established, with several founded before the year 2000.
Key players include EU Careers by EPSO, which selects candidates for EU institutions, and HR Rail, focused on recruiting for rail transportation. Liantis supports self-employed entrepreneurs and employers, while Daoust offers a broad range of HR services including interim staffing and outplacement. A notable pattern is the strong presence of organizations dedicated to public service and social welfare alongside traditional recruitment agencies.

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 11, 2026.
