The Hauts-de-Seine department hosts a significant cluster of large and mid-sized real estate companies. These firms are involved in a wide range of activities including property development, transactions, management, and consulting for both residential and commercial projects. Notable companies include ORPI, a real estate organization with a large property database; BNP Paribas Real Estate, offering comprehensive services across Europe, the Middle East, and Asia; Bouygues Immobilier, specializing in sustainable urban development; and Stéphane Plaza Immobilier, a network providing personalized client support.
Most of these companies are headquartered in cities such as Clichy, Boulogne-Billancourt, Issy-les-Moulineaux, and Montrouge, indicating a strong geographical concentration within the department. While some are established players founded in the 1950s and 60s, like Bouygues Immobilier and BNP Paribas Real Estate, there is also a presence of more recent firms such as Stéphane Plaza Immobilier (2014) and in'li (2017), showing a mix of established expertise and newer ventures.

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.
