Built for the sport
Belt, stripe and grading vocabulary baked into the data model — not bolted on from a generic gym template.
Tenant-isolated
Your data, only yours
Every query is scoped to your gym, with Postgres Row-Level Security policies as defence in depth.
Stripe Connect
Your own account
Payments flow through your Stripe account, not ours. Your money, your dashboard, your reconciliation.
How it works
You teach. We move you in.
Apply
Five fields, two minutes. We reply within one business day and jump on a short call to make sure MatFlow fits how you run your academy.
Application
We set everything up with you
Send us your member list — any format. We import it, record belts and stripes, apply your branding, and connect payments to your own Stripe account. You watch it happen; you don't do it alone.
We set it up with you
Your members get the app
Everyone receives a login invite to your branded member app — schedule, check-in, rank progress. The iPad kiosk goes by the door. Training carries on; the admin disappears.

Fundamentals
What you get
Six things every BJJ academy needs.All of them in production.
Belt & stripe tracking
Per-discipline rank systems with attendance-based eligibility checks. Full promotion history, audit trail, and a queue that surfaces eligible members automatically.
Kiosk check-in
iPad at the door, HMAC-tokened and isolated from the admin interface. Members tap their name; attendance and class-pack credits write atomically with no double-charge risk.
Branded member portal
Your gym's name, logo and colours on every screen — schedule, announcements, personal attendance, rank progression. One branded PWA, zero app-store fees.
Attendance-driven promotions
Set minimum sessions and minimum months per rank. The promotion queue runs itself. You confirm; MatFlow provides the evidence.
Payments that reconcile
Stripe Connect per tenant, idempotent webhooks, refunds with auto-void of class-pack credits. Cash and comp payments recorded with audit metadata. No orphan rows.
Reports that actually run
Weekly attendance trends, monthly signups, member status mix, top classes by fill rate — live from the database, not a stale CSV export from last Tuesday.
Every feature above is live in production today — not a roadmap item.
Pricing
One plan. Everything included.
No tiered upsell, no per-seat add-ons. Larger academies — get in touch.
