A sociology graduate with a minor in history, Valentin Sansonetti is an educator and amateur tennis player (best ranking: -2/6). Fervent defender of popular education, he followed a training with L'Ardeur and realizes in 2021 a gesticulated conference entitled "The sport session was ok, but can we go play now?", in which draws up a socio-historical analysis of the sports phenomenon. He also gives workshops on how to counteract doublespeak and bafflebag. Valentin is the author of several articles on French reviews.

With L'Agency, he is working on an essay with a sociological focus in which he examines the collective unthinking and biases that run through sport as an activity and as an institution.
