The companies listed are primarily higher education institutions and professional training organizations based in Nantes, many of which are substantial in size. They range from long-established universities to more recent vocational training networks. Nantes Université, Audencia, Groupe Alternance, and IRSS are examples of these, offering a wide array of educational programs from academic degrees to professional certifications.

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.
