# Top 30 Research Services companies in the Bouches-du-Rhône department

Tamtam tracks 47 Research Services companies headquartered in the Bouches-du-Rhône department. This list ranks the 30 largest by number of employees on LinkedIn, led by IRD, Lycée Saint-Exupéry (Marseille) and CIML. Their median headcount is 62. Half of them were founded in 2000 or later. The most common headquarters are Marseille (25) and Aix-en-Provence (4).

The Bouches-du-Rhône department hosts a significant concentration of research services organizations, predominantly mid-sized institutions and public entities. These include the IRD, a public research institute focused on development in Southern countries; CIML, which conducts immunology research; and CEREGE, a European center for environmental geoscience. The presence of entities like Lycée Saint-Exupéry also indicates a focus on educational research and development.

A notable pattern among these organizations is their strong concentration in Marseille, which serves as a major hub for scientific inquiry. The research spans diverse fields, from fundamental sciences like astrophysics (Laboratoire d'Astrophysique de Marseille) and particle physics (Centre de Physique des Particules de Marseille) to specialized areas such as oceanography (Mediterranean Institute of Oceanography MIO) and cancer research (CRCM - Centre de Recherche en Cancérologie de Marseille).

## 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.
