The companies listed here are primarily recruitment and staffing agencies based in Ille-et-Vilaine, alongside some business consulting firms with strong HR focuses. These are mostly mid-sized companies, with several established players alongside younger firms. Groupe SAMSIC, for instance, offers facility management and HR services, while Interaction Interim provides temporary work and recruitment across various sectors. Hellowork specializes in digital platforms for employment, and Solano focuses on staffing for transportation and logistics. CATALYS Conseil offers HR strategy and management consulting.
A notable pattern among these companies is their strong concentration in Rennes, with many headquarters located in the city.

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.
