Andy Souwer started his kickboxing journey when he was only seven years old at the Ling Ho Gym in Den Bosch. His talent was evident from the beginning, winning all of his fights, across all weight classes, and becoming the Dutch Champion.
He subsequently fought his first A-Class MTBN Title match in 1998, winning on points at only 16 years old. By the time he turned 18, he had already secured three different World titles.
Souwer's first journey to Japan was in 2002 to compete in the S-Cup 2002 shoot boxing competition, which he won after defeating Chinese sanshou title challenger Zheng Yuhao. The following year, he made his K-1 debut and won his first K-1 World Max champion title in 2005. In 2007, he became the K-1 World Max Champion, defeating Gago Drago, Albert Kraus, and Masato in the championship. However, he lost to Masato in Masato's retirement match at the Dynamite!! 2009 event.
Souwer's career was not without its challenges, as he experienced financial disputes with promoters. For instance, he was scheduled to face Naruepol Fairtex at Fighterzone Kickboxing World Series MAX in Singapore on 25 February 2012, but due to non-payment by the promoter, the fight ended up not happening.
Despite such setbacks, Souwer continued to make a name for himself in the martial arts world. He won the 2012 Shoot Boxing World Tournament held in Tokyo, Japan, after defeating Kem Sitsongpeenong in the quarter-final stage and knocking out Hiroki Shishido in the semis. He defeated stablemate and student Henri van Opstal by unanimous decision in the final.
He also took a unanimous decision over Yasuhiro Kido at the K-1 World MAX 2013 World Championship Tournament Final 16 in Mallorca, Spain.
Souwer's achievements in kickboxing are numerous, and he is a two-time K-1 World Max champion, a four-time Shootboxing World Tournament champion, a It's Showtime 70MAX World Champion, and a multiple-time S-Cup champion.
He also made his professional boxing debut in 2014, winning by TKO in the fourth round against Paata Varduashvili.
Despite his many accolades in the martial arts world, Souwer announced his retirement following his loss to Marat Grigorian at ONE Championship: First Strike Kallang, Singapore on 15 October 2021.
Leveraging his extensive experience, Souwer has joined Warrior Collective to share his knowledge and techniques with aspiring fighters worldwide.
