Equipe de la Ciotat

Stilog I.S.T. is a global software editing company based in France. Created in 1991, Stilog I.S.T. develops innovative solutions, using the most recent technologies available. We acquired expertise through the development of time-saving applications for the largest international organizations. This expertise is today reflected in the realization of tailor-made IT projects and in the development of Visual Planning, a collaborative scheduling platform for all kinds of businesses.

30 years after the company was created, Christophe Poirmeur and François Berthelot, founders of Stilog I.S.T., are still running the business with the same core values that have brought them success: independence, innovation, quality and responsiveness.

Visual Planning has now gathered more than 5,000 customers around the world and a 100,000+ user community.

A dedicated team of consultants helps on each implementation to ensure that the system’s capabilities are used at their best.

At the same time, our first-of-class customized development services are praised by major global firms in the most demanding industries, from aeronautics to energy.  In order to support our growth in North America, Stilog, Inc. was created in 2013.
