When Olivier Dez was diagnosed with Parkinson's disease, in 2015, he had the idea to create an application for people with the same condition. The app, called Zenaïde, was developed by DCO Media +.

While still in high school, Quentin conceived the Deaf Tab, an electronic device that detects sound as soon as an alarm starts and sends a visual or a vibrant message, to help ensure deaf people are aware of it. The device enables deaf people to find a certain autonomy at home or at work.

Quentin, the leader of the project, conceived, with the help of his friends, Deaf tab, the device that detects every sound alarm in a house such as a fire alarm, the doorbell or the baby phone.
