SaaS · Next.js dashboards
PTbase. A SaaS for coaches, built by the team you'd hire.

The challenge
Coaches juggle clients across sheets, calendars and notes apps. Nothing talks to anything. PTbase set out to collapse that into one coach-first workspace.
Our approach
Full-stack build: Next.js app router with server components for heavy dashboards, Supabase + row-level security for multi-tenant data, Clerk for auth, Stripe for billing. Real-time updates via Supabase channels so coaches and clients see the same view instantly.
We obsessed over the 'program Monday morning' workflow, the moment coaches used to lose two hours to admin.
The result
Pilot coaches reclaimed ~8 hours a week. The product moved from prototype to paying accounts in under a quarter.
