Grenoble's electronics and semiconductor sector is characterized by a mix of established research institutions and specialized firms. CEA-Leti, with 1223 employees, develops micro- and nanotechnologies for industrial applications, while CEA Tech focuses on ICT, energy, and healthcare technologies. EASii IC designs custom integrated circuits, and MICROOLED specializes in OLED Near-Eye Displays.
The companies here primarily focus on semiconductor manufacturing, electronic components, and related software and research. A notable trend is the presence of several younger companies founded in the last decade, such as Quobly (2022) developing quantum computers, eLichens (2014) providing air quality solutions, and DIAMFAB (2019) synthesizing diamond for semiconductors.

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.
