First nomadic (Nantes, Lyon, Bruxelles and Paris), the fair has progressively built itself thanks to its exhibitors and visitors, specialised in all the areas of technics of performance, with strong networks and lasting relationships. Since 2006, the JTSE take place at the Docks of Paris. Despite this growth, the quality of visitors not only remained but is steadily increasing. Moreover, this space promotes conviviality and meeting between national and international know-how; this is now the JTSE trademark.

Since the beginning, your membership has continuously grown: in 1998, JTSE counted 45 exhibitors and 750 visitors; the 2017 edition welcomed over 140 exhibiting companies and 6 093 visitors.
