Overview
GymGrow (Grow HQ) is a multi-tenant gym operating system with three connected surfaces. Superadmins onboard gym owners and manage platform settings. Gym owners run branches, members, staff, classes, programming, and finances with role-based permissions. A public TV webapp displays session programming on gym screens. Together they cover the full loop from platform onboarding to floor-ready workouts.
Gyms connect a Stripe Express account to collect payments and manage transactions, refunds, and payouts. Programming created in the gym dashboard publishes to the TV display for members.

Development and Challenges
The hardest parts were modeling multi-tenant gyms with branch-level data, keeping role and permission checks consistent across every screen, wiring Stripe Express so owners could onboard and take payments without mixing accounts, and keeping the TV display readable from across a gym floor while staying in sync with published programming.
