Tamtam tracks 30 Real Estate companies headquartered in the Seine-Maritime department. This list ranks all of them by number of employees on LinkedIn, led by Habitat 76, Logeo Seine and Alcéane. Their median headcount is 19. Half of them were founded in 1999 or later. The most common headquarters are Rouen (13) and Le Havre (5).

The real estate sector in Seine-Maritime is dominated by social housing organizations. Habitat 76 manages over 28,000 social housing units, while Logeo Seine provides residential solutions in Normandy. Other notable entities include Alcéane, which oversees 15,000 units, and 3F Normanvie, with 24,000 units.

Headquarters are concentrated in Rouen and Le Havre, reflecting these cities' roles as major urban centers in the department. While social housing providers form the bulk, there are also firms like BIAS Immobilier offering tailored advice and property management, and ICM Investissement Clés en Main supporting real estate investors.

## 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 14, 2026.
