About

Caius Michael Geribo is a grey belt from Alliance in CA, ranked #56 globally with a Prodigy-tier rating of 8,087. He is the highest-volume fighter in this batch with 166 matches across 22 tournaments, and his 87% win rate crushes the 49% grey belt average. His 86% submission rate nearly doubles the 47% belt average, and he has claimed 29 golds with a 77% gold rate — almost triple the 28% belt norm.

His 20 competitive wins and 125 expected wins reflect a massive sample size that validates his rating. His best results come from Grappling Industries events — 3 golds in Rhode Island, 3 golds in Philadelphia, and 2 more golds in a second Philadelphia outing. He competes exclusively through Grappling Industries and IBJJF, a tight two-org focus. His no-gi rating (4,950) outpaces his gi (4,190), and his dominant DVI sits at the 18th percentile for trend — suggesting his rating, while elite, has plateaued rather than climbed recently.
