San Diego, California
San Diego is one of the densest BJJ markets in the world. The Saulo Ribeiro / Xande Ribeiro lineage runs deep, Atos has its global HQ here, and the proximity to military installations means a steady flow of students with serious training time and frequent PCS moves. The market is mature: members compare academies on lineage, competition results, and how hard the rooms train.
The local picture
Why it works for San Diego
OLM's belt_promotions table stores every promotion as an append-only lineage entry — discipline, from-rank, to-rank, issuing org, promoter, and a free-text note. When a Marine PCSes to Camp Pendleton with a brown belt from Atos, your gym sees the verified history; their old academy still owns the original promotion record. For owners running tight back-to-back kids and adult schedules, class templates auto-generate sessions with separate caps, and check-in pulls a child's guardian profile so a parent can sign waivers and tap their kid in without rejoining the queue.
In every BJJ gym, anywhere
Belt & stripe tracking that follows the athlete
Every promotion is recorded with the issuing professor, date, and note. When a student ever moves or tries another academy that also runs OLM, they bring their full lineage — not a self-reported belt and a story about their old gym. You verify years of history in seconds.
One profile. Every OLM academy.
Training journal entries, class check-ins, and belt history are keyed to the member, not locked to your database. New members walk in with real, verifiable progression — and the ones who leave keep their journal. Athletes respect that.
Training journal with AI coach
After class, members log tags or drop a voice note. OLM maps their game to an 8-axis chart — Guard, Passing, Submissions, Sweeps — and coaches them on weak areas.
Seminar & open-mat billing
One-off Stripe charges for seminars, private lessons, or drop-ins. Flat 3% platform fee — proportional to ticket size, no monthly subscription on top.
Churn alerts before they quit
AI Monitor watches attendance patterns and flags members 14 days before they churn. You text them, not an apology email after they cancel.
Waivers that hold up
Finger-drawn e-signatures, SHA-256 audit trail, IP stamp. Minor forms with parent second-signer. Annual auto-renewal reminders.
