A personal presentation, inspiring words, a moving overall talk. Listening to this talk is the best thing that could happen to any entrepreneur—or anyone, for that matter. Some will hopefully leave feeling empowered, even if they’re currently struggling. Others will be delighted because they already possess those qualities within themselves. Either way, everyone leaves the room with better thoughts, feelings, and inspiration. I couldn’t ask for more!

Marc Wallert was a speaker at our national convention in Frankfurt, where we welcome around 600 guests each year—and his presentation left a lasting impression.
It’s not just his personal story that’s remarkable, but above all the way his talk truly resonated with every generation in our network. Afterward, I spoke with colleagues in their early 20s, mid-40s, and over 60—and everyone was thrilled because each person took away something deeply personal from that hour with Marc.
That is exactly what makes an exceptional speaker in my view: inspiring people in different life situations equally and encouraging them to reflect.
I’m currently reading his book as well and can highly recommend it.
Thank you so much, Marc, for being part of our convention!

Marc Wallert’s presentation was an absolute highlight for us. We look back on the entire event with great enthusiasm—and this was immediately reflected in the reactions of our customers. We received overwhelmingly positive feedback even on the evening of the event.

Many were particularly impressed by how approachable, authentic, and at the same time compelling Marc Wallert conveyed the topic of resilience. His personal story and the experiences he shared made the content tangible in an extraordinary way and left a lasting impression.

You can sense it in him every minute: He doesn’t just talk about resilience—he lives it. It was precisely this human, honest approach that deeply moved and left a lasting impression on our audience.

The collaboration—both before and after the event—was consistently professional, straightforward, and to the point.

We highly recommend Marc Wallert—and this certainly won’t be our last event together. In short: sensational!

It’s not really the kidnapping he went through, but the lesson he learned from it! I’m grateful that I was able to listen to him.

Even though the circumstances Mr. Wallert described were extraordinary, I found myself relating to many of the points he made. It was a talk I listened to very intently, while at the same time asking myself where I currently stand in my life. My personal motto wasn’t just inspired by this great talk: “You never know what it’s for.” Even if you don’t get an answer right away, life knows which path is the right one. Thank you very much for the interesting talk. And all the best to Mr. Wallert and his family. My personal life is currently a journey filled with a lot of self-reflection.

I’m currently preparing a presentation, and his contribution has helped me better understand the reasoning behind the person I’m presenting on. But aside from that, I myself benefited from this truly enriching evening.

The presentation was very engaging and interesting—the way the speaker shared the knowledge gained from experience and personal insights, and how they further developed and conveyed these ideas to the audience, was truly outstanding—thank you for that.
We wish you continued success and good health.

Not an abstract high-flyer, but true to life; he has practically undergone a whole course of psychoanalysis.

Marc Wallert was an exceptionally inspiring speaker for our corporate event. He captivated the audience from the first to the last minute - I was literally hanging on his every word. His way of speaking touched me deeply emotionally and I was really in raptures.

I was particularly impressed by how confidently he mastered the balancing act between a very serious, personal and emotional story and humorous moments. This balance not only made his messages accessible, but also had a lasting effect.

I have taken away numerous impulses for my day-to-day work that help me to look at challenges in a new way and tackle them with more inner strength. Marc Wallert is a speaker who doesn't just talk, he moves. He is absolutely convincing, both professionally and personally. Absolutely recommendable.

Hello Mr. Wallert, I followed the kidnapping at the time and was very happy that it turned out well for you and your family. I very much hope that you and your family were able to mentally come to terms with what happened.
