How a Bordeaux Sports Coach Automates Client Follow-Up with WhatsApp AI
Case study: a Bordeaux sports coach who automated his client follow-up via WhatsApp AI and saved 15 hours per week.

McKinsey (2023): coaching and training professionals who automate client follow-up recover an average of 14 hours per week and can double their client portfolio.
