These multinational companies in Grenoble are predominantly mid-sized to large organizations, with a strong presence in IT services, manufacturing, and research. Notable examples include Tessi, which manages customer relations and document processes, and ARaymond, a manufacturer of fastening and fluid connection systems. CEA-Leti focuses on micro- and nanotechnologies for industrial applications, while ESRF - The European Synchrotron is an international science facility for advanced research.

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.
