Onoff Telecom

Onoff Telecom

Triple world champion in rollerblading, presenter and participant in television programs, serial entrepreneur... Taig's professional life has always been filled with great challenges. During his umpteenth hospital stay, he thought of a new challenge, just as athletic as his career up to now, and decided to completely reinvent his entrepreneurial adventure. His goal? To dust off the world of telecommunications, which has been lagging behind for 30 years, by offering an innovative solution and placing telephone numbers in the cloud. Thus, the Onoff Telecom adventure was born, guided by Taig's vision!
