iKropp
Management SaaS platform for aesthetics clinics and health professionals — from scheduling to anamnesis.
The purpose
Aesthetics clinics, biomedical professionals and aestheticians deal with complex operations: scheduling for multiple professionals, client records with procedure history, detailed anamnesis, service and product management. Most use generic tools that don't understand the sector's workflow.
iKropp solves this with a vertical platform: built specifically for the aesthetics and health sector, covering the complete operational cycle in a single system. Over 50,000 active users rely on the platform daily.
The result is real operational control — professionals focus on patient care, not spreadsheets. Managers have visibility over scheduling, revenue and productivity without switching between tools.
