About Johann

I help sports coaches and dietitians who manage long-term follow-ups to better frame their clients' commitment from the start, to avoid follow-ups that fizzle out or end too soon.
I design internal assistance systems (invisible to the client) that help identify truly involved profiles, structure onboarding, and reduce the mental load associated with follow-up.
These systems allow you to save up to 10 hours per week and reduce the mental load related to client management.
This allows you to support more clients and grow your business without hiring.

Experience

  • Agence de structuration & qualification client – Sport & Nutrition
    Founder – Qualification & client structuring systems for sports coaches and dietitians
    CONSULTING AND AUDITS
    January 2026 - Today (5 months)
    I help sports coaches and dietitians who offer long-term follow-ups to better frame their clients' commitment upstream, in order to avoid follow-ups that lose steam or become energy-consuming.
    I design internal assistance systems (invisible to the client) that help qualify profiles, structure onboarding and follow-up, and reduce the mental load associated with unmotivated clients, without automating the human relationship.
    Result: 10 hours saved per week, clearer decisions from the first exchange, more long-term engaged clients, and a smoother, more sustainable business, without hiring or multiplying ineffective follow-ups.
