Early Life and Education

These experiences undoubtedly shaped Chatri's philosophy towards life and success, as evidenced in his later business ventures and contributions to martial arts.

Martial Arts Background

Sityodtong’s path to becoming one of Asia's most influential figures in martial arts began during his childhood days in his native Thailand. His journey started under the guidance of Papa Daorung, a coach based in Thailand, and senior trainer at the "Sityodtong Gym".

At the time, Kru Yodtong Senanan, a legendary trainer from the renowned Sityodtong Camp in Pattaya, Thailand, was the the grandmaster of the gym. The respected Senanan recognized Chatri's potential and bestowed upon him the ring name Yodchatri Sityodtong, a name that he would bring honor to in over 30 professional Muay Thai bouts.

Guided by Senanan, a known mastermind in the realm of Muay Thai, Chatri intensively trained in the martial art, ultimately earning the esteemed status of a certified senior Muay Thai instructor.

Senanan's trust in Sityodtong ran so deep that, prior to his death, he appointed him as one of only four designated conservators of Sityodtong Muay Thai globally, an honor reserved for only the most devoted and proficient students.

Embracing his thirst for the martial arts, Chatri did not limit himself to Muay Thai. After moving to the United States for his higher studies, he began training in Brazilian Jiu-Jitsu at the Renzo Gracie Academy in New York City.

In this new discipline, Sityodtong once again demonstrated his dedication and skill. Under the tutelage of BJJ World Champions Rafael Gordinho Lima and Leandro Brodinho Issa, he earned his blue and purple belts.

By 2021, his aptitude and commitment to the sport led BJJ World Champion Alex Silva to award Chatri his brown belt, with the blessing of Renzo Gracie himself.

Through these experiences, Chatri cultivated a profound understanding of martial arts, a discipline that shaped him into a resilient and centered individual. In 2019, his exceptional contributions to the martial arts community were recognized, as he was inducted into the illustrious Black Belt Magazine Hall of Fame.

All of this serves as a testament to his dedication and passion for martial arts–a journey that began as a child in Thailand and followed him all the way to Singapore, where he reshaped Asia's combat sports landscape.

Career in Business and Finance

From modest beginnings to scaling the heights of financial success, Chatri Sityodtong's career in business and finance has been nothing short of extraordinary.

His journey began as an investment analyst at Fidelity Investments, a role that exposed him to a wide range of industries and provided him with a comprehensive understanding of market dynamics and financial landscapes. This experience laid the foundation for Chatri's future entrepreneurial endeavors.

Recognizing the potential of a rapidly digitizing world, Chatri partnered with Harvard classmate, Yau Soon Loo, to launch Nextdoor Networks, an e-commerce infrastructure company based in San Francisco.

This was Chatri's first foray into the world of startups, providing valuable insights and experiences that would guide and shape his career trajectory in the years to come. Despite the challenges and intense competition in the tech startup space, the company thrived and was eventually sold for $20 million.

Driven by ambition and equipped with his newly accumulated wealth, Chatri entered the world of hedge funds. He became a Managing Director at Maverick Capital, a US$12 billion hedge fund which gave him the added experience and confidence to launch his own hedge fund, Izara Capital Management.

Being the helmsman of a US$500 million fund was a position of immense responsibility and pressure, yet it was here that Chatri honed his investment acumen, preparing him for the next phase in his career.

In 2008, combining his business acumen and love for martial arts, Chatri launched Evolve MMA, a chain of martial arts academies sprawled across Asia.

This venture set the scene for what was to come, intertwining his business skills with his lifelong passion for martial arts. It served as the initial stepping-stone to his groundbreaking decision to create ONE Championship just three years later.

As the founder and current Chairman and CEO of ONE Championship, Chatri is at the helm of Asia’s first multi-billion-dollar global sports media property.

His decision to venture into an initially void sports market space in Asia and his deep-seated commitment to promoting Asian values and martial arts have been instrumental in the organization's extraordinary success.

The secret to ONE Championship's long-lasting growth and success under Chatri's stewardship stems from the organization's focus on respect and values. It wasn't merely about physical prowess or combat skills, but rather about the stories behind these martial artists.

Their journey, their resilience, and their pursuit of passion became the heart of the promotion, providing a refreshing narrative, often overshadowed in the realm of competitive sports.

The forward-thinking nature of Chatri's management didn't stop at elevating the sport's storytelling. Recognizing ONE Championship's potential as a media powerhouse, a strategic partnership was forged with Amazon, broadening its reach further.

Moreover, a significant trade (ONE trading for Demetrious Johnson, offering Ben Askren) with the Ultimate Fighting Championship (UFC) enriched ONE Championship's talent pool, marking a milestone in the MMA landscape.

It wasn't just about building the brand; Chatri aimed to nurture the ecosystem that sustains the sport. To underscore this, he addressed the issue of weight-cutting by implementing hydration tests for its athletes' safety and fair competition, a practice that gained significant international recognition.

Yet, even against its towering success, the organization's genuine respect for its athletes and steadfast commitment to embodying the true spirit of martial arts remains the cornerstone of its brand.

But his philanthropy efforts do not end here. Sityodtong, understanding the vital role of education and shelter in a child’s life, actively contributes to Boys' Town Home and the Singapore Children's Society.

These organizations enable a secure future for abandoned children, or those in distress, through quality education and holistic care.

Beyond his financial contributions, Sityodtong values the power of personal involvement.
