My goal is to build the most comprehensive BJJ encyclopedia anywhere — but good,
accurate data is genuinely hard to come by. Records, gyms, belts and nationalities
are pieced together from public and community sources, so some of it is incomplete,
outdated, or flat-out wrong.
That's where you come in. If you spot something off, tell me and I'll fix it — every
correction makes this better for everyone. This website wouldn't be possible without
the community.
