# List of public sector organisations in the Hérault department

Tamtam tracks 68 public sector organisations headquartered in the Hérault department. This list ranks the 30 largest by number of employees on LinkedIn, led by CHU de Montpellier, CIRAD and Université de Montpellier Paul-Valéry. Their median headcount is 280. Half of them were founded in 1989 or later. The most common headquarters are Montpellier (24) and Béziers (2).

These public sector organizations in Hérault are primarily large institutions in healthcare, education, and government administration. Among them are CHU de Montpellier, a leading hospital, CIRAD, a research center for sustainable agricultural development, and Université de Montpellier Paul-Valéry, providing higher education in arts, languages, and social sciences. Also present are Académie de Montpellier, overseeing national education, and Département de l'Hérault, a local public administration.

A clear pattern is the strong concentration of these major public entities in Montpellier, which serves as the administrative and academic hub for the department. This indicates a centralized structure for public services and higher education within the region.

## 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.
