Health & Fitness SaaS

FitCore

FitCore was growing fast, but its no-code MVP could not support reliable scheduling, branded tenant experiences, or a smooth trainer dashboard on mobile.

Challenge

Concurrent class registrations were causing conflicts, trainers needed a responsive dashboard, and the founder needed an architecture ready for serious growth.

Solution

  • Rebuilt the product as a multi-tenant SaaS with branded subdomains for gyms and personal training businesses.
  • Implemented real-time class booking, waitlist logic, mobile-first trainer workflows, and progress tracking for members.
  • Added billing infrastructure with Stripe Connect plus operational reporting for attendance, workouts, and payments.
