The Delta adventure started in 2018, during a training session on a regular climbing hangboard: "I wish to be able to train on new holds, or with a pulley system, with a TRX... easily, quickly, and without my wall looking like Swiss cheese !".
This need that Théodore, one of the co-founders, raised at the time was shared by his climbing partners, Noé and Samuel, the 2 others of the future trio of the Delta company.
Théodore then proposed to invent a fast and efficient clipping system for climbing holds: that's how the idea of the Deltaboard emerged !
