# Oktagon MMA

Oktagon MMA is a mixed martial arts organization based in the Czech Republic and Slovakia, considered the largest Czech-Slovak organization. The founders and at the same time its owners are Pavol Neruda (formerly Šipkovský) and Ondřej Novotný.

## History

The organization was founded in June 2016, when it came up with the reality show Oktagon Challenge. The project culminated in the Oktagon 1 tournament. Gábor Boráros and Jakub Běle faced each other in the final. The winner of the main match and the entire reality show was Gábor Boráros, and Oktagon started a series of gala evenings. The following 3 series brought several winners from Slovakia. Samuel Krištofič, Karol Ryšavý and Lucia Szabová completed the collection of champions. The final of the 5th series took place at the Oktagon 20 tournament , in which Roman Paulus won on points over Tomáš Zajac.
Oktagon organizes several tournaments every year in the largest Czech and Slovak arenas and cities as well as Germany and England. It created a reality show with professional fighters called Oktagon Challenge, Project X, which followed the journey of an ordinary person to the cage, Project Y - an all-female MMA reality show, and last but not least, a talk show about fighters and people from the Oktagon Majk scene. It also publishes the weekly Oktagon Magazín which maps the scene of combat sports. The organization now has more than 450,000 fans on social networks and YouTube, where their videos had over 46 million views in 2024.
