The Haute-Garonne department hosts a concentration of IT services and software development companies. These firms primarily serve industrial sectors like aerospace and defense, as well as healthcare and retail. They range from mid-sized companies to larger groups, with a notable presence of firms established in the 1990s and early 2000s.
CIMPA PLM Services deploys Product Lifecycle Management solutions, while mipih provides digital healthcare support. Infomil develops IT infrastructure for grocery retail, and Valiantys specializes in enterprise agility with Atlassian. A common pattern is the strong presence of companies headquartered in Toulouse and its immediate surroundings.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
