The professional services sector in Grenoble features a mix of IT, engineering, and legal firms. Companies like Tessi (customer relations, payments, document processes) and BETREC IG (building and infrastructure project design) are larger players, while firms such as Enerdata (energy and climate analysis), AXE INFORMATIQUE (management software for SMEs), and Sogilis (innovation booster through technology) represent mid-sized and younger enterprises. Neovision specializes in AI solutions, and Lexan Avocats offers multidisciplinary business law support.
A notable characteristic of these firms is their strong local roots, with all headquarters based in Grenoble. The sector demonstrates a blend of established companies founded in the 1960s and 1970s, like BETREC IG and Tessi, alongside a significant number of younger firms established in the 2000s and 2010s, such as Sogilis and Neovision, indicating ongoing development in specialized professional services.

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.
