As a competitor

Daniel de Groot wins at the CBJJEE south american championship

As a competitor I’ve travelled the world to compete. I’ve made a name for myself in the European and Brazilian circuits. In 2021 I received my black belt.

I love competing, not just for the rush or for the feeling of winning, but also to test the techniques I teach. There are plenty coaches that tell you to do things they haven’t applied in high-level competition. I don’t want to be one of them. I want to show only techniques I am 100% sure will work, even against tough resistance. 

My main accomplishments are winning the IBJJF nogi European, nogi Brazilian championships and I got Bronze at the ADCC trials.

With the gi I’ve medalled at the IBJJF Europeans and I’ve won the IBJJF Curitiba Open. 

As a coach

In 2015 I started teaching classes at the Erasmus University. In 2018 I started teaching classes at The House Fight Company, one of Brazil’s best gyms. I’ve taught classes and seminars around the world, from Germany to Los Angeles and from Bulgaria to Brazil.

In 2023 I opened my own gym in the middle of Rotterdam: Haven BJJ. There we offer classes for all levels, from complete beginners to elite competitors.

Those elite competitors have competed and won at some of the biggest tournaments in the World. Including Europeans, Worlds and superfights at Grapplefest and Polaris.

Outside of jiu jitsu

In 2011 I started training submission grappling after being inspired by the UFC, especially the videogame. Since then jiu jitsu has been by my side.

I finished my bachelors in Public Administration in 2016 at the Erasmus University Rotterdam. Then I obtained my masters degree in Crisis & Security management at Leiden University.  After that I decided that I would focus solely on jiu jitsu as a career.

I live in Rotterdam and when I’m not training jiu jitsu I like food, both eating and preparing it. Next to that I go to the gym several times a week and I love reading about (military) history. Stoic philosophy is something else I’m very interested in.
