John Kavanagh

Coach of UFC Champion Conor McGregor & MMA World MMA Coach of the Year 2016, 2017

"Ruben always realises how to steer the mind to a place where it's working at its strongest capacity. His analytical approach lets him see how to play into one's own strengths and circumvent or fix weaknesses. He knows how to create the highest mental energy levels. That made him a huge asset in leading the preparations of my professional fight team."

“Ruben’s coaching has given me energy that I didn’t know I was lacking in the first place. When I now go into a challenge it is an excitement I want to embrace rather than something to fear. It woke up the fighter in me.”

Thilak Mahendran

Senior Client Engagement Lead, AI at IBM

"The individual coaching has been extremely insightful to better understand & align my overall goals in a way which I had not previously explored. Ruben's transfer of knowledge from his educational and MMA background gave me a new view on my life and how to lead other people more effectively."

Jan Graffelder

CEO Look & Graffelder

"We doubled our company size from 15 to 30 employees. Working with them in different teams was sometimes very difficult. The Program helped me a lot to improve my leadership skills. It changed my whole day and my complete life. I felt more confident. I felt stronger. I felt more energy going into every day. Entering the room I felt a lot more assertive...I felt less stressed, happier and balanced."

Stefan Radtke 

Managing Partner, Mapdid GmbH

"The coaching by Ruben is a great experience on more than one level. It's intense and demanding while being a lot of fun at the same time. As coach, he's pushing you while giving you the freedom to push yourself to your own limit. Due to Ruben's authentic personality and his background in sports and education, it's a very motivating setting to develop yourself further. Plus, Ruben is a very smart, kind and humble person - great to talk to and to spend time with. Highly recommended!"

Bartek Maciaga,

Everyone knows Ruben as a great fighter. In his role as a Coach, he puts his experience to excellent effect: Training materials and coaching sessions are practice-oriented, very effective and above all, infinitely exciting.

Sven Wunderlich

CEO, Bewa Security

"Ruben passes on his deep knowledge of self-management in stressful situations to my entire leadership team at my company Bewa-Security, which currently employs over 800 employees. He instilled a new type of confidence, inspiration and energy. I, myself also make full use of his coaching for my personal development and highly enjoy the results."

Jonas Billstein

Cage Warriors Champion

Ruben's program really was a challenging undertaking, but his understanding of the human mind has helped me to win the Cage Warriors title. His training and mental system is bulletproof and made me stronger than ever.

Tanner Lauka 

IT Recruiting Manager, Robert Half Technology

"I would like to express a heart felt thank you to Ruben Crawford for accepting me into his 7 day leadership challenge. To say the results were transformative would be saying the least. Ruben's methods and training allowed me to put together a vision for my future that I was not yet able to see for myself. His research in the fields of leadership, physiology, and psychology coupled with his experience as a professional fighter provided a clear path for me to understand my own vision for the future and the current obstacles I've put in my own way. I would highly recommend anyone who is looking to develop their leadership capacity or tap into their true potential to reach out to Ruben."

Olivier Moncousin

Founder & CEO, Spartan Sports

Thanks again for the opportunity with the coaching. I was on a super mental height and saved us almost 50,000 euros through the ideas I had.
