# List of electronics and semiconductor companies in France
Tamtam tracks 846 electronics and semiconductor companies headquartered in France. This list ranks the 100 largest by number of employees on LinkedIn, led by Valeo, CEA and SAGEMCOM. Their median headcount is 523. Half of them were founded in 1982 or later. The most common headquarters are Paris (14), Toulouse (4) and MΓ©rignac (3).
These French companies are primarily involved in electronics, telecommunications, and IT services, with a strong presence in automotive technology, semiconductor manufacturing, and industrial electronics. The list includes a mix of large established groups like Valeo, which develops automotive technology solutions, and CEA, a public body conducting research in energy and IT. Mid-sized firms such as SAGEMCOM, providing broadband and entertainment solutions, and Soitec, a leader in semiconductor materials, are also prominent.
A notable pattern is the concentration of headquarters in the Paris region, including Paris itself, Bois-Colombes, Rueil-Malmaison, and Bezons. Companies like Bull, a global leader in high-performance computing, and Socomec Group, specializing in low voltage electrical networks, highlight the diverse yet interconnected nature of the electronics and IT sectors represented.

## 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.
