Gianni Grippo is widely regarded as one of the leading figures of the 'Berimbolo Generation' of Brazilian Jiu-Jitsu, having built that reputation in the lower belt divisions of the sport where he conquered 6 world titles (4 with the gi and 2 in no-gi). Grippo competed under Renzo Gracie's New York City academy up until the brown belt rank, switching to the neighboring Marcelo Garcia Academy (MGA-Alliance) who ultimately awarded Gianni his black belt in October 2013.
