Tamtam tracks 585 companies headquartered in the Puy-de-Dôme department. This list ranks the 100 largest by number of employees on LinkedIn, led by Michelin, Euromaster and Weldom. Their median headcount is 177. Half of them were founded in 1992 or later. The most common headquarters are Clermont-Ferrand (65) and Aubière (12).

The largest companies in Puy-de-Dôme are predominantly large groups and mid-sized firms, with a strong presence in manufacturing, retail, and public services. Michelin, a major tire manufacturer, is the largest employer. Other significant companies include Euromaster, providing vehicle maintenance, and Weldom, specializing in home improvement.

## 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.
