# The 30 largest hardware manufacturers in the Hauts-de-Seine department
Tamtam tracks 199 hardware manufacturers headquartered in the Hauts-de-Seine department. This list ranks the 30 largest by number of employees on LinkedIn, led by Schneider Electric, Thales and Worldline. Their median headcount is 2,581. Half of them were founded in 1981 or later. The most common headquarters are Rueil-Malmaison (4), Bagneux (3) and Boulogne-Billancourt (3).
The Hauts-de-Seine department hosts a concentration of large and mid-sized hardware manufacturers, with a significant presence in industrial technology, defense, and telecommunications. Companies like Schneider Electric specialize in energy management and automation, while Thales focuses on cybersecurity and defense. Nexans is a key player in cable systems, and Dassault Aviation designs military aircraft and business jets. This group includes established firms like Faiveley Transport, founded in 1919, and newer entities such as SAGEMCOM, established in 2008.
Many of these companies are engaged in critical infrastructure and advanced technological solutions. For instance, Worldline and Ingenico are prominent in financial services and payment technology. GE Renewable Energy and GE Grid Solutions contribute to the energy sector, particularly in renewable resources and power delivery. A notable pattern is the strong representation of companies involved in global industrial and technological solutions, often with a focus on sustainability and digital transformation.

## 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.
