Kampfwerk, the gym manager for martial-arts schools

Field notes

Kampfwerk connects trial-session availability, reminders, digital signatures, direct-debit authorization, and contribution tracking instead of leaving those steps in separate lists and folders. Its example interface shows 141 active members, 29 trial sessions in a month, and 121 of 128 contributions paid automatically. The site also presents white-label options for individual gyms and centralized controls for franchise operators, including location-level prices and contracts.
