# List of financial services firms in the Seine-Maritime department
Tamtam tracks 32 financial services firms headquartered in the Seine-Maritime department. This list ranks the 30 largest by number of employees on LinkedIn, led by Matmut, Cr茅dit Agricole Normandie-Seine and Caisse d'Epargne Normandie. Their median headcount is 22. Half of them were founded in 2005 or later. The most common headquarters are Rouen (12), Le Havre (7) and Mont-Saint-Aignan (3).
The financial services sector in Seine-Maritime is largely shaped by established insurance companies and regional banks. Matmut, with over 4,200 employees, provides diverse insurance products, while Cr茅dit Agricole Normandie-Seine and Caisse d'Epargne Normandie are significant regional banking institutions. SPB Group specializes in insurance and assistance offers for daily products, and Helvetia Insurance France focuses on enterprise risk and marine insurance. La MAE is known for child and family insurance. These are generally mid-sized to large organizations.
A notable pattern is the concentration of headquarters in Rouen and Le Havre. Rouen hosts Matmut, La MAE, and several of their subsidiaries, alongside venture capital firm NCI. Le Havre is home to SPB Group, Helvetia Insurance France, and maritime insurance broker GUIAN. Bois-Guillaume also serves as a hub for regional banks.

## 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 13, 2026.
