Biography
William Tackett is an American Brazilian Jiu-Jitsu black belt and one of the most prominent young competitors specializing in no-gi grappling. Born in California, he moved to Austin, Texas, at a young age, where his martial arts journey began at age eight. He is the older brother of fellow professional grappler Andrew Tackett.
Tackett represents Brazilian Fight Factory. He quickly established himself as a prodigy, competing and defeating high-level adult black belts while still a colored belt, earning his black belt in 2021.
He is known for an well-rounded skillset that allows him to dominate in any position. Tackett expertly utilizes wrestling to dictate the match, combines a precise leglock game with dynamic guard play, and executes tight and loose guard passing to secure the pin. This adaptability makes him a threat to any opponent.
Tackett recently signed an exclusive contract with UFC to compete in their professional BJJ events, a move he views as transformative for his career and for the sport. This decision grants him access to the UFC Performance Institute and provides the consistent competition and financial stability that highlights his focus on family and professional longevity.
