The Isère department's largest public sector organizations are primarily involved in healthcare, education, and government administration. These are large-scale employers, with several exceeding 1,000 employees. Key entities include CHU Grenoble Alpes, a major regional hospital, and CEA-Leti, which develops micro- and nanotechnologies. Government administration is represented by Grenoble-Alpes Métropole, overseeing urban development, and Ville de Grenoble, managing municipal services.

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.
