Whether your goal is to get fitter, learn self-defense, or challenge yourself with something new, Node Grappling offers high-quality Jiu-Jitsu training in a structured, safe, and supportive environment.
Jiu-Jitsu is more than just a martial art — it’s a constantly evolving system of problem-solving under pressure. It’s strategy and movement, strength and creativity. A fight, a sport, and an art form, uniquely shaped by every practitioner.
At Node, we’ve built a community that welcomes everyone — beginners and experienced athletes alike.
As an official affiliate of the Mavericks Jiu-Jitsu community (founded by Jonathan Thomas and Espen Mathiesen), our members benefit from a world-class training program and a global network.

Goal-oriented Training
We have different types of training programs for adults, juniors and kids to help you achieve your goals, regardless of your fitness level or preferred grappling style.
We offer classes in Brazilian Jiu-Jitsu, Submission Grappling (No Gi), and Judo.
Our Culture
Safety first - we are a martial-art gym, but we believe that safe training is most important.
Flat hierarchy - We have no masters or professors. Higher belts are a resource for learning, not a symbol of authority. Ask anyone for advice, and be open to roll with everyone, regardless of rank.
Speak up - feedback and constructive criticism is valued, speak up to help us improve.
Tame your ego - The mat is a place for learning, you tap and get tapped. Be humble and thank your training partner.
Personal cleanliness - Jiu Jitsu is a close quarter combat sport. Come to class clean with clean gear and trimmed fingernails. Wear flip-flops off the mat.
Wear what you want - we believe in freedom of expression, but your attire must be safe for grappling. Spats or shorts and rashguards work the best. In Gi classes we ask you to wear a Jiu-Jitsu kimono.
Have fun - most importantly, have fun rolling!

Our instructors
Rob
Rob, originally from Canada with Filipino roots, has lived in Estonia since 2011. Outside the gym, he works as a music engineer and producer, collaborating with global icons like Stevie Wonder and Bruno Mars, as well as Estonian stars. A father of three. Rob loves pizza, favors the color brown, and would be a T-Rex wearing underwear on his head if he could. Rob teaches kids’ jiu jitsu and lunchtime no-gi classes. Co-founder of Node Grappling. Brown Belt in BJJ.
Efo
The guy who never smiles. Migrated to Estonia back in 2021 as a refugee from the happiest place on Earth- Finland. Efo has a unique background in military and security. As a Finnish Army veteran he has a unique approach to the sport and is more than eager to help out fellow veterans and law enforcement officers to learn unarmed combat skills. Responsible coach for Monday morning and Wednesday evening classes. Co-founder of Node Grappling. Black Belt in BJJ.
Sophia
The mysterious one. Sophia is from the USA but has been living in the Baltics long enough to have lost all skin tone. No one is sure what she does off the mats, but at Node Grappling, she's sharing the secrets she's learned living and training in six different countries across four continents since 2013, when her Jiu Jitsu journey began. Sophia occasionally leads mobility/active-stretching with Jiu Jitsu recovery in mind. Brown Belt in BJJ.
Tommi
Tommi traded football sliding tackles for berimbolos and never looked back. Now a BJJ brown belt, coach, and co-founder of Node Grappling, he brings experience from training and competing worldwide—including at Unity Jiu Jitsu in New York—back to Tallinn, which he has called home for over a decade. You’ll find him running the evening gi classes, where inverting isn’t required… but it’s highly recommended.
Sergei
