# The 30 largest research institutes in the Isère department

Tamtam tracks 31 research institutes headquartered in the Isère department. This list ranks the 30 largest by number of employees on LinkedIn, led by CEA-Leti, ESRF - The European Synchrotron and ILL - Institut Laue Langevin. Their median headcount is 100. Half of them were founded in 1995 or later. The most common headquarters are Grenoble (17) and Saint-Martin-d'Hères (8).

The research institutes in Isère are primarily focused on scientific and technological innovation. These are mostly large public research organizations and higher education institutions, often founded in the mid-20th century. Notable entities include CEA-Leti, which develops micro- and nanotechnologies for various industrial applications, and ESRF - The European Synchrotron, an international facility for advanced synchrotron radiation research.

A significant pattern is the strong concentration of these institutes in Grenoble and its immediate surroundings like Saint-Martin-d'Hères. Many, such as ILL - Institut Laue Langevin, specialize in fundamental research across physics, chemistry, and biology, while others like CEA-Liten focus on renewable energy and decarbonization technologies. Grenoble INP - UGA Recrutement represents the higher education sector, offering engineering and management programs.

## 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.
