The largest companies in Échirolles operate across diverse sectors, including professional training, retail, real estate, and healthcare. Reliance, with 1557 employees, specializes in optimizing organizational performance. KIS provides self-service photo booths and laundry machines, while SDH manages social housing units. Clinique des Cèdres is a modern medical facility offering comprehensive surgical and maternity services.
A notable pattern among these companies is their focus on both local services and broader market reach. For instance, apperton offers sterilization services for healthcare facilities in France, and Made In Design is an online retailer of designer furniture across Europe. Many of these firms, such as SYDEV (founded 1998) and Made In Design (founded 1999), were established around the turn of the millennium.

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 11, 2026.
