AI coaching SaaS for fitness creators
“A platform for fitness creators to sell personalized AI-assisted coaching programs with habit tracking and community challenges.”
Real demand — creators already monetize coaching and hate the manual admin.
Fatal flaw: Creators churn if results aren't visible fast; retention hinges on client outcomes, not features.
- Trainerize. Win on AI-personalized program generation and a creator-first storefront.
- Notion + Stripe DIY. Replace the duct-tape stack with one tool built for coaching delivery.
The blueprint
CoachLoop
The coaching delivery layer fitness creators run their business on.
Wedge & Positioning
Start with mid-size fitness creators (10k–100k followers) who already sell programs over DMs and spreadsheets. Be the tool that turns their method into a sellable, trackable program in an afternoon.
Monetization
Stripe subscriptions: Creator $39/mo (up to 50 clients) and Pro $99/mo (unlimited + community). Take rate 0% to undercut marketplaces; you win on tooling, not a cut.
Architecture
Next.js + Supabase. Program builder, client app (PWA), habit check-ins, and an AI assistant that drafts week-by-week plans from the creator's template.
Data Model
creators, programs, clients, enrollments, check_ins, messages, challenges.
Agent Team & Tool Policies
A program-drafting assistant proposes plans; the creator approves before anything is sent to a client.
Launch Plan (guarded)
Hand-onboard 10 creators. Approval gate before any client billing or bulk message goes out.
Growth Loop
Each client app is branded to the creator and links back — clients become leads for new creators.
Risks & Approval Gates
Biggest risk: outcomes. Instrument client progress from day one. Human approval before payments and bulk messages.
The build pack
Problem
Fitness creators sell coaching but deliver it over DMs, PDFs, and spreadsheets — it doesn't scale and clients drop off.
Target user
Creators with 10k–100k followers already earning from coaching.
Core jobs
Build a program once, sell it, deliver it, and see client progress.
Success metric
Weekly active clients per creator (proxy for retention).
Build "CoachLoop", a coaching delivery SaaS for fitness creators, with Next.js + Supabase. Screens: (1) Creator dashboard listing programs + client activity; (2) Program builder (title, weeks, daily tasks); (3) Client PWA showing today's plan with check-off + note; (4) Auth (email). Data: creators, programs, clients, enrollments, check_ins (see fields). Add Supabase RLS so a creator only sees their own clients. Stripe subscriptions with two plans (Creator $39, Pro $99) and a customer portal. Clean, mobile-first UI. No fake data — wire real Supabase queries.
