# 30 leading hardware manufacturers in the Isère department
Tamtam tracks 143 hardware manufacturers headquartered in the Isère department. This list ranks the 30 largest by number of employees on LinkedIn, led by ARaymond, Verkor and Sames. Their median headcount is 316. Half of them were founded in 1985 or later. The most common headquarters are Grenoble (8), Montbonnot-Saint-Martin (3) and Meylan (2).
These Isère-based companies are mostly mid-sized firms, with a focus on manufacturing and industrial equipment. They include ARaymond, founded in 1865, which designs fastening systems, Sames, established in 1925, providing equipment for applying paints and sealants, and Rossignol Group, a winter sports equipment manufacturer since 1907. Other firms like LYNRED specialize in infrared technologies, and Petzl designs exploration tools.
A notable pattern is the concentration of these companies in and around Grenoble. This includes Verkor, a battery producer founded in 2020, CORYS, a simulation company, and Minitubes, which specializes in precision metal tubing. This geographic cluster suggests a regional hub for industrial and manufacturing activities.

## 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.
