Tamtam tracks 159 AI companies 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 Coface. Their median headcount is 1,025. Half of them were founded in 1993 or later. The most common headquarters are Levallois-Perret (5), Boulogne-Billancourt (4) and Courbevoie (2).

These companies in Hauts-de-Seine largely represent the IT services and software development sectors, alongside larger industrial and defense groups. The companies are a mix of established firms and more recently founded enterprises. For example, Schneider Electric, founded in 1836, focuses on energy technology, while Thales, a multinational, specializes in cybersecurity and defense. Doctolib, founded in 2013, provides healthcare technology solutions, and Vusion, established in 1992, develops AI-powered digitalization for retail.

A clear pattern among these companies is their strong orientation towards digital transformation and AI integration across various industries. Many are headquartered in Levallois-Perret, Rueil-Malmaison, and Le Plessis Robinson.

## 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.
