The largest companies in Yvelines include major players in diverse sectors, predominantly large groups. Dassault Systèmes, for instance, pioneers virtual worlds for sustainable innovation. Groupe PSA (now Stellantis) is a leading automaker, while Eiffage Énergie Systèmes designs and maintains energy systems. ArianeGroup develops space launch systems, and SAVENCIA is a family-owned food group. These firms showcase a strong presence in engineering, manufacturing, and services.
A notable pattern is the concentration of headquarters in Vélizy-Villacoublay, home to several of the largest employers like Dassault Systèmes, Groupe PSA, and multiple Eiffage entities. This suggests a significant industrial and technological hub within the department, with a mix of very large established companies and some older, yet still substantial, enterprises such as Peugeot, founded in 1810.

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.
