The Loire-Atlantique department hosts numerous marketing and communications agencies. Companies like swimming pool, with 465 employees, specialize in integrated communication and marketing for B2B. Mediapilote guides brands through transformations, while ALTAVIA NANTES designs marketing strategies for networked companies. IDEUZO focuses on HR consulting and communication, assisting with recruitment strategies. These firms offer a range of services from brand strategy and creative content to digital transformation and lead generation. Most of these companies are mid-sized to large firms, indicating a well-established market.
A notable pattern among these agencies is their concentration in Nantes. Many of the larger firms, such as swimming pool, ALTAVIA NANTES, IDEUZO, and Groupe The LINKS, are headquartered in the city.

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.
