What some of our clients say...

"You have created a fantastic negotiation course, which was performed by you in a very good way. Very good content, clear language, a lot of space for questions and reflections. Thank you! Very good case. I was positively surprised – this was a digital training that overreached my expectations."
"THANK YOU for extremely good and powerful means that are fun to see working in real life!” The reason I write to you is because I think it must be fun to see that what you teach is used and especially fun to see when it goes the right way! I have recently been in two negotiations, both of which have ended very well. In both negotiations, I have taken advantage of "arts" learned from the course."
«I used Roar as a sparring-partner, and I found our conversations outstanding and will continue to benefit from them in the future. It’s always good to have a mirror held up to you – it makes self-reflection easier.»
"That was so nice for me, working for a trading company from next year. I became aware of the importance of Preparation and Improvision before negotiating. I would definitely applicate this lesson to my job."
"Very satisfied customers/members after your arrangement (rumors say that several more nascent disputes were resolved quite immediately thereafter)."
