Tamtam tracks 86 companies headquartered in the Ardennes department. This list ranks the 50 largest by number of employees on LinkedIn, led by EVENEMENTIEL, Centre Hospitalier Intercommunal nord-Ardennes and HSD Human Resource Solutions. Their median headcount is 52. Half of them were founded in 1958 or later.

The companies listed in the Ardennes department are primarily mid-sized firms, with a notable presence in manufacturing, government administration, and healthcare.

## 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.
