These companies in Grenoble are primarily large and mid-sized organizations with significant in-house research and development capabilities. The list features a strong presence of institutions in healthcare, such as CHU Grenoble Alpes, a major regional hospital, and CEA-Leti, which develops micro- and nanotechnologies for healthcare. Education is also prominent, with Grenoble Ecole de Management offering business programs and Grenoble INP - UGA providing higher education in engineering.

A notable pattern is the concentration of advanced technology and research. ESRF - The European Synchrotron and ILL - Institut Laue Langevin are international science facilities offering advanced research tools. Verkor produces low-carbon batteries, and ARaymond designs fastening and fluid connection systems. Many companies, like Cegelec CEM in nuclear engineering, are involved in highly specialized industrial applications.

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.
