The public sector organizations in Morbihan are primarily involved in government administration, healthcare, and education. These are large organizations, with the Département du Morbihan managing public services and GROUPE HOSPITALIER BRETAGNE SUD providing extensive medical care. Other key entities include Service Départemental d'Incendie et de Secours du Morbihan, which handles emergency interventions, and Académie militaire de Saint-Cyr Coëtquidan, which trains army officers.
A notable pattern is the concentration of headquarters in Vannes, which hosts several major entities like morbihan habitat, focused on social housing, and Golfe du Morbihan - Vannes agglomération, coordinating public services across 34 municipalities. This indicates Vannes as a central hub for public administration and services within the department.

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 11, 2026.
