“The Dream”
Stamp Fairtex, born Sunisa Srisen on August 8, 1997 in Rayong Province, Thailand, is one of the most important and visible female combat sports athletes in the world today. As the first fighter in ONE Championship history to hold two World Titles simultaneously, capturing both the atomweight Muay Thai and atomweight kickboxing world championships, Stamp has shattered glass ceilings in a sport that was long dominated by male fighters and has become a global ambassador for women's Muay Thai. Her charismatic personality, technical versatility, and willingness to test herself across multiple combat disciplines have made her a role model for young female fighters around the world and one of the most recognizable faces in Asian combat sports.
Stamp's journey into Muay Thai began, unusually, at the relatively late age of eleven, when she accompanied her father to the local gym and decided she wanted to try training herself. She quickly showed a natural aptitude for the sport and began competing in local bouts, displaying the kind of focus and work ethic that would later define her professional career. By her teenage years she had joined the legendary Fairtex Gym in Pattaya, one of Thailand's most respected and internationally famous training camps, where she worked under world-class trainers alongside some of the best male and female fighters in the country. The Fairtex name, which she adopted as her ring moniker, has become synonymous with elite Muay Thai training, and Stamp quickly established herself as the gym's most famous female representative on the global stage.
Before signing with ONE Championship, Stamp built an impressive amateur and professional resume that included strong performances at the IFMA World Championships, where amateur Muay Thai fighters from around the world compete for the most prestigious international titles outside the professional stadium circuit. Her success in these tournaments caught the attention of ONE Championship, which was in the process of building a women's atomweight division across multiple disciplines including Muay Thai, kickboxing, and mixed martial arts. Stamp signed with the promotion in 2018 and wasted little time making her presence felt, winning the inaugural ONE atomweight Muay Thai world championship in her very first year on the roster and then adding the ONE atomweight kickboxing championship soon after, becoming the first athlete in the promotion's history to hold titles in two striking disciplines at the same time.
What truly set Stamp apart, however, was her decision to cross over into mixed martial arts while still at the peak of her striking career. Starting almost from scratch in the grappling and wrestling aspects of MMA, she committed herself to learning the new disciplines with the same focus and dedication she had brought to Muay Thai. Her transition was remarkably successful, culminating in her victory in the ONE Women's Atomweight World Grand Prix, a one-night tournament that established her as a legitimate contender at the highest levels of women's MMA. Throughout her MMA career she has continued to refine her grappling while still relying on the punishing left body kick and sharp punching combinations that made her famous as a striker, and she has developed into one of the most well-rounded female combat athletes in Asia.
Beyond her in-ring accomplishments, Stamp Fairtex has become a cultural phenomenon in her own right. Her cheerful, approachable personality, her signature pre-fight dancing during ring walks, and her willingness to engage with fans on social media have earned her a massive following that transcends traditional combat sports audiences. She has appeared on television shows, in commercials, and in countless feature stories as one of the faces of Thailand's new generation of international sports stars. For young girls in Thailand and across Asia, she has demonstrated that women can compete at the very highest level of combat sports while remaining true to themselves, and her influence on the growth of women's Muay Thai is impossible to overstate. Stamp Fairtex is not just a champion but a pioneer, and her impact will be felt in the sport for generations to come.
