Matheus Gabriel Pinheiro Barros

Matheus Gabriel Pinheiro Barros was born on June 10, 1997, in Manaus, the capital of Amazonas State in northwestern Brazil, on the banks of the Negro River. Growing up in one of South America's most distinctive urban environments, the young Matheus gravitated naturally toward football and soccer, competing in local youth leagues before martial arts entered the picture.

His introduction to Brazilian Jiu-Jitsu came at age eight in 2006 — and the catalyst was an unlikely one. His grandmother, convinced that martial arts discipline would channel his excess energy and curb a pattern of mischief at school, enrolled him in classes. That decision proved to be one of the most consequential of his life. His first instructor, Alcenor Alves — widely regarded as one of Brazil's premier coaches for young BJJ athletes — guided Matheus from white belt through green-white belt. Coaches Sammi Dias and Diogo Dutra subsequently took over his development, carrying the work forward through his formative competitive years.

By his mid-teens, Gabriel's exceptional talent had become impossible to overlook. At 15, he made a bold and defining decision: leave Manaus and travel to Rio de Janeiro to join a BJJ scholarship project run by coach Márcio Rodrigues. The program was designed to identify and develop promising young athletes, and the training environment it produced was remarkable. Among Gabriel's training partners during this period were future elite competitors Erberth Santos, Lucas Barbosa, and brothers Ygor Rodrigues and Yago Rodrigues.

Gabriel spent nearly two years immersed in that high-caliber setting, absorbing the intensity and technical depth that elite Rio training demanded. When the program lost its funding and he returned to Manaus, the Rio chapter had already done its work — exposing him to elite-level competition and methodology at a critical developmental age, and laying a foundation that would prove invaluable in the years ahead.

The path from Manaus to international prominence began with a personal connection. John Kleicy Kurchat, owner of a Checkmat franchise in Manaus and a friend of Gabriel's, recognized the young athlete's potential and referred his name to Kaiser Girão, a respected BJJ coach based in Dallas, Texas. Girão's decision to bring Gabriel to America set the stage for one of the sport's most explosive purple belt careers.

Building a Complete Game in Dallas

Training out of Girão's Checkmat academy, which operated inside the Mezger MMA gym in Dallas, Gabriel had access to a uniquely well-rounded performance environment. He developed his physical conditioning under MMA veteran Guy Mezger and sharpened his wrestling under two-time All-American Melvin Lofton — a combination that complemented his already formidable grappling foundation.

At purple belt, the results spoke clearly: 96 wins from 102 matches, just two losses in his weight class, and 76 submissions. His 79% submission rate was the highest recorded among his peers at that level, marking him as one of the most dangerous finishers in his age group anywhere in the world.

Institutional Support and Purple Belt Titles

The scale of his performances attracted institutional backing. The Exclusive Athletes Program — a fund created by João Paulo Bertuccelli, owner of Exclusive BJJ gym — identified Gabriel as a rising star with precarious financial support and provided him with a salary and health coverage. For a young athlete far from home, that support proved critical to his ability to remain competitive at the highest level.

His purple belt campaign included titles at the 2016 IBJJF World No-Gi Jiu-Jitsu Championship, the 2017 IBJJF Pan Jiu-Jitsu Championship, the 2017 IBJJF American Nationals, and the 2017 IBJJF American No-Gi Nationals.

The transition to brown belt intensified rather than slowed Gabriel's momentum. Competing at featherweight, he went virtually undefeated at that level — his only loss coming by disqualification in the absolute division, not in his weight class. His overall brown belt record stood at 33 wins, 1 loss, and 0 draws, with 23 submissions and a submission ratio approaching 70%. Those numbers placed his brown belt run among the most dominant in recent BJJ history for his age group and weight class.

Making History on the Professional Circuit

Beyond the record, Gabriel made history on the professional circuit by becoming the first athlete in Fight to Win Pro history to win titles in four different categories — a milestone that underscored both his finishing ability and the breadth of his technical game. His brown belt titles included the 2017 IBJJF World No-Gi Jiu-Jitsu Championship and the 2018 IBJJF World Jiu-Jitsu Championship in the gi, the latter serving as the capstone of an extraordinary run through the colored belt divisions.

In June 2018, immediately following his gi World Championship victory at brown belt, Kaiser Girão promoted Matheus Gabriel to black belt — a promotion earned through performance rather than tenure, and one that carried the full weight of everything Gabriel had built to that point.

The transition to black belt brought immediate and emphatic results. In 2019, Gabriel won both the 2019 IBJJF Pan Jiu-Jitsu Championship and the 2019 IBJJF World Jiu-Jitsu Championship at featherweight, establishing himself as a legitimate world-class competitor from the opening months of his black belt career. The 2019 World Championship win announced his arrival at the sport's highest level and validated the long developmental arc that had taken him from the banks of the Negro River to the top of the featherweight podium. The rapid success reflected the collaborative coaching network — stretching from Manaus to Rio de Janeiro to Dallas — that had shaped his game across more than a decade.

Gabriel's ability to compete consistently deep into major tournaments continued through 2020 and 2021, even as the featherweight division grew increasingly competitive. In 2020, he reached the final of the IBJJF Pan Championship, earning a silver medal and confirming that his 2019 results were no aberration.

The 2021 season offered a mixed but revealing picture of where Gabriel stood among the world's elite. He captured both the IBJJF Pan No-Gi Championship and the IBJJF Brazilian Nationals title, affirming his dominance at the continental and national level. At the 2021 IBJJF World Jiu-Jitsu Championship, however, he fell just short of the top step — reaching the featherweight final before being defeated by Fabricio Takaka, who claimed the division via triangle choke. Gabriel earned the silver medal, a result that reflected both his elite standing and the depth of competition at world level. For reference, the lightweight division at those same Worlds was won by Renato Canuto — a distinction worth noting, as the two weight classes are frequently conflated in reporting.

The 2021 campaign illustrated the fine margins at the top of international BJJ. Gabriel remained one of the featherweight division's premier competitors — capable of winning major titles and reaching world finals — while facing opponents who had equally reached the apex of the sport.

In 2025, Gabriel added a defining new chapter to his competitive legacy by capturing the IBJJF World Championship title in the lightweight division (76KG) — a deliberate step up from the featherweight division (70KG) where he had built his reputation. The lightweight title demonstrated his capacity to compete and excel at a higher weight class, expanding the scope of what his career had already achieved. João Pedro Bueno Mendes claimed the 2025 featherweight title, meaning Gabriel's second IBJJF World Championship at black belt came in an entirely new weight category rather than on familiar ground.

The achievement gave Gabriel the distinction of holding IBJJF World Championship titles across two different weight divisions at black belt — a marker of competitive longevity and the kind of physical and technical adaptability that separates good champions from exceptional ones.

The coaching lineage that shaped Matheus Gabriel reflects a collaborative network of instructors spanning three cities and more than a decade. Alcenor Alves laid the technical and philosophical foundation during Gabriel's earliest years, guiding him from white to green-white belt with the expertise that has made Alves one of Brazil's most respected youth coaches. Sammi Dias and Diogo Dutra continued that development, before Márcio Rodrigues provided the elite-level environment of the Rio scholarship program. Each figure contributed something distinct to the competitor Gabriel became.

Ultimately, it was Kaiser Girão — operating out of his Checkmat affiliate in Dallas, Texas — who served as the architect of Gabriel's elite competitive game and the coach who formally recognized his readiness for black belt. Girão's decision to bring Gabriel to America, and the environment he built around him in Dallas, proved transformative. The broader Checkmat network provided international support, competition infrastructure, and the team identity that sustains long careers at the sport's highest level.

The unconventional trajectory of Gabriel's development — from Manaus to Rio de Janeiro to Dallas — produced a competitor shaped by multiple training philosophies and diverse competitive experiences. That path may well account for the technical breadth and competitive resilience that have defined his career across both the colored belt and black belt divisions.
