# Rendez-vous de 45 min with Jonathan DIAZ

> 45 minutes en visio, gratuit et sans engagement. Vous me racontez comment tourne votre logistique aujourd'hui, Excel, emails, téléphone. Je repère avec vous les tâches qui mangent vos heures et je chiffre ce qu'un agent peut reprendre. Vous repartez avec un rapport d'une page, à garder même si on ne travaille pas ensemble.
