Marc Herkner · Leadership · Practice · Digital products
I connect leadership, hands-on experience and digital products.
I lead teams in the fitness industry, am a proud dad and build my own apps. Real operational problems are my starting point: I understand them from practice and turn them into working products that have to prove useful in everyday life.
Three apps in closed testing. Access is free, requested by email and usually enabled personally within 1–2 days.
