Beatriz “Bia” Mesquita is one of the most decorated women in IBJJF history. Under Leticia Ribeiro at Gracie Humaitá she built a complete gi game across guard and passing, set a black-belt Worlds gold record (10 titles as of 2021), and won ADCC gold at −60 kg in 2017.

She later added MMA competition while training at American Top Team. For technique readers, her profile pairs with closed-guard, armbar, and pressure-passing pages rather than a single signature gimmick.
