  • Konquer

    Konquer is a networking application for boxing and MMA. It will help fighters and trainers set up fights in the amateur and professional ranks. Having a fight lined up motivates you to train hard, and when they fall through, or you can't get matched up—you lose motivation, and your dreams suffer. Not anymore.

    Konquer will allow fighters and trainers to create profiles, connect, message, and search for fighters by weight class, experience level, number of fights, among other things. This will streamline the matchmaking process, and empower fighters to focus on training, fighting, and achieving their dreams!

    Fighters can build their profile, promote themselves, and fight their way to the top!

    Konquer was built for the warriors that dream of becoming champions and pushing themselves to the limit!
