Our History & Philosophy
Since 2004, our activity has focused on the development and commercialization of the Sémaphore seeing to foresee solution. Born from recognized expertise in the demanding maritime and port sectors, Sémaphore seeing to foresee is much more than a CMMS. It is a visual and robust tool faithful to its motto 'seeing to foresee'.
