Our history

Origins with Guian

GUIAN has been a name well established in the marine insurance sphere of Le Havre since 1931. In 1931, René Guian established in Le Havre as “sworn marine insurance broker”. Offices were then opened in Paris, Marseille, Saint Malo and in Vendée.
From the beginning, GUIAN was synonymous with experts’ assessment, proximity with its clients, trust-based relationships established on long-term basis with a strong field culture. All this was possible thanks to GUIAN’s teams,  made of specialists with experimented profiles and various backgrounds, sometimes coming from the professional universe of its clients.

Marriage with SeaSecure

At the end of March 2018, the company GUIAN became part of the SEASECURE group, along with SEASECURE SA and SEASECURE SARL. GUIAN and SEASECURE had similar activities with complementary geographical implementations and different clients’ profiles. This allowed to bring together a workforce of 45 people, with complementary expertise, to offer the marine industry close technical and geographical proximity.
