Keeping a booking tool ruthlessly minimal for solo practitioners

Keeping a booking tool ruthlessly minimal for solo practitioners targets a $1.2B = 6M solo practitioners x $200 ARPU/year total addressable market with medium saturation and a year-over-year growth rate of 8-15% annual growth in SMB scheduling & appointment tooling.

Key trends driving demand: fragmentation fatigue -- users are tired of bloated marketplaces and prefer single-purpose, reliable tooling; privacy-first expectations -- practitioners want client data kept off public platforms as regulations increase; API commoditization -- payments, SMS, and calendar APIs make building a secure scheduler low-cost and fast; micro-automation via AI -- small, explainable AI features (smart reminders, suggested times) improve UX without requiring massive models.
