Half the drop-offs
Clients stay
We asked more than 500 trainers how many clients they lost before Kaizer and how many they lose now. Drop-offs fell by half. A client who opens an app and sees their routine, their videos and their progress does not feel they are paying for the same thing as one who gets an Excel over WhatsApp.

The time that comes back

The unit is per client. The scaled figure is never published on its own.

The marketplace brings people
