Co-founded a profitable B2B SaaS for physiotherapy clinics in 12 months with zero external funding; now used daily by 40+ clinics with 92% annual retention. The multi-tenant Flask + Next.js + Supabase platform automates booking, billing, and workflows with p99 <200 ms response and 99.9% uptime while requiring minimal maintenance.

The Challenge

Clinics were losing hours to fragmented tools and outdated calendars. The market offered hospital‑grade systems that were overkill, or generic tools poorly suited to daily clinical work. The challenge: design the right product from scratch, validate product‑market fit with non‑technical users, and reach profitability without external capital—while keeping operations simple and clinical workflows reliable.

Solution & Approach

A pragmatic, fast‑cycle strategy: validate willingness to pay before building, solve the core job first (the agenda), and iterate in tight loops on real feedback. Ruthless prioritization, clear UX for non‑technical profiles, and operational automation to scale without friction.

Research & Validation

  • Interviewed 50+ clinic owners to understand workflows and pain points
  • Validated willingness to pay before writing a single line of code
  • Built an MVP in 8 weeks focused on scheduling, their most painful task

Technical Execution

  • Multi-tenant SaaS with Flask + Next.js for rapid iteration
  • GDPR-compliant with automated backups and minimal maintenance
  • Mobile-first design, optimized for clinicians on the move
  • p99 under 200 ms response times, even on unstable clinic Wi-Fi

Growth & Operations

  • Bootstrapped with direct sales; referral-driven growth thereafter
  • Hands-on onboarding with biweekly success calls until activation
  • Flat pricing to maximize simplicity and adoption
  • 99.9% uptime with automated monitoring and alerts
