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.

## 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.
