# 30 leading Software Development companies in the Val-de-Marne department

Tamtam tracks 57 Software Development companies headquartered in the Val-de-Marne department. This list ranks the 30 largest by number of employees on LinkedIn, led by Intalio, Infopro Digital Automotive and DIRISI : Direction Interarmées des Réseaux d'Infrastructure et des Systèmes d'Information. Their median headcount is 56. Half of them were founded in 2002 or later. The most common headquarters are Cachan (5), Gentilly (5) and Ivry-sur-Seine (4).

The Val-de-Marne department hosts a concentration of software development companies, ranging from established firms to younger enterprises. These companies primarily focus on creating specialized software solutions for various industries. Among them, Intalio, founded in 1990, provides digital transformation solutions, while Infopro Digital Automotive offers data and software for the automotive aftermarket. DIRISI manages IT systems for the Ministry of Armed Forces, and Nat System develops tools for complex business applications. Imagino, established in 2017, specializes in customer data platforms.

A notable pattern among these companies is their diverse specializations within the software sector. For instance, SAB is now SBS provides IT solutions for financial institutions, Sefas Innovation focuses on omni-channel customer communication, and Mezzoteam offers a platform for construction project management. This indicates a broad application of software development expertise across different markets, rather than a single dominant niche.

## 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.
