# 30 leading education providers in Nantes

Tamtam tracks 50 education providers headquartered in Nantes. This list ranks the 30 largest by number of employees on LinkedIn, led by Nantes Université, Audencia and Groupe Alternance. Their median headcount is 249. Half of them were founded in 1985 or later.

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.

A notable pattern is the strong presence of organizations dedicated to adult continuing education and professional development, alongside traditional higher education.

## 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.
