Scaling a Gym SaaS from MVP to 10,000 Users
How I rebuilt a fragile gym MVP into a production-ready multi-tenant SaaS platform handling 10,000 members and $200k/month in recurring revenue.
Business Context
The problem space and success criteria
The client had a working MVP with serious performance issues, no multi-tenancy, and billing that broke under load. They needed a complete rebuild — fast.
Project goals
- Migrate to multi-tenant architecture without data loss
- Implement reliable recurring billing via Stripe
- Achieve sub-200ms API response times under load
- Build a self-service onboarding flow for new gym owners
Technical Response
How the delivery was structured
Solution
Redesigned the data architecture for multi-tenancy, rebuilt the billing layer on Stripe Subscriptions, implemented Redis caching, and introduced a queue-based async job system.
Architecture
Multi-tenant Laravel API (subdomain routing) → Vue.js SPA → MySQL (per-tenant schemas) → Redis cache → AWS EC2 (auto-scaling) → S3 for media assets
Outcomes
Lead result
10,000+ members migrated with zero data loss
- $200,000+ monthly recurring revenue processed
- API response times reduced from 800ms to under 180ms
- System running for 14 months with 99.95% uptime
