The public sector organizations in the Loire department are predominantly large institutions, primarily in healthcare, higher education, and government administration. Notable examples include CHU de Saint-Etienne, a major healthcare provider; Université Jean Monnet Saint-Etienne, offering multidisciplinary education; École des Mines de Saint-Étienne, an engineering school focused on sustainable innovation; and Département de la Loire, which manages social integration and infrastructure. The majority of these organizations are headquartered in Saint-Étienne, with a significant presence also in Roanne.
A common pattern observed is the prevalence of long-established institutions, with many founded in the mid-20th century or earlier, such as Département de la Loire (1793) and École des Mines de Saint-Étienne (1816), indicating a deep-rooted public service infrastructure in the region. These entities collectively manage essential services for the local population.

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.
