Boston, Massachusetts
Boston's BJJ scene is small, technical, and disproportionately competitive. Mass BJJ and a tight bench of independents serve the city, the Back Bay, and Cambridge, drawing heavily from the Harvard-MIT-BU graduate-student demographic. Members tend to be analytical, tournament-minded, and willing to drive an hour to Worcester or Providence for a Saturday seminar with the right instructor.
The local picture
Why it works for Boston
OLM's analytics dashboard exposes the underlying numbers — daily active members, weekly cohort retention, churn-risk scores per member — with full CSV export so a Harvard PhD member can run their own analysis if they want. The AI Monitor surfaces churn risk based on attendance drop-off patterns over a 14-day window, with the data-source class sessions visible behind the score. For tournament-team members, a separate add-on subscription handles competition-team dues stacked on the base membership, with separate Stripe line items for clean accounting.
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
