EXPERTS
Experience, not hype.
Over 400 speakers have taken the stage at our event so far—from Stefanie Stahl to Gerald Hüther, from Frank Thelen to Bodo Schäfer. And international luminaries such as Tony Robbins, Sadhguru, Wim Hof, and Barack Obama also share their knowledge with us. These are people with decades of experience from whom you can truly learn valuable life lessons.
OUR STORY
We know what it feels like to start over.
We started out very small ourselves in 2012 (back then under the name Gedankentanken) with a simple series of talks in Cologne called the “Rednernächte.” Today, Greator is Germany’s largest platform for personal development. We know from our own experience the doubts, the hurdles, and the tough steps that are part of real growth—because we’ve gone through this process ourselves as a team and as a company.

I took one of my courses—Lebensschule Pro—with you guys. I attended the Greator Festival 2025—I’ll be back in 2026 too—and I went to see Tony Robbins! Inspiration, knowledge, sharing, and pure joy of life. See for yourselves. I give it 5 stars. You’ll definitely go home smarter than when you arrived—if you want to.

Dear Dieter Lange, dear Greator Team, your work is the most valuable thing I have encountered so far in the field of continuing education and self-development. So far, I’ve found answers here to almost all of life’s questions (I’m not quite done with my training with you yet), especially from Dieter, who, with his life experience and expertise, is a master of his craft. My thanks go out to all of you. It’s a true school of life and personal growth, no matter which path you take. Thank you for being here!

The name says it all. It’s a wonderful platform. You’ve made personal development accessible to everyone. What an achievement—and what a wonderful contribution! Last year, I decided to enroll in Dieter Lange’s School of Life. The wisdom and perspectives shared there are worth their weight in gold. Thanks to you and the amazing Dieter Lange, I’ve decided to share and pass on this knowledge as a life coach. Thank you so much for everything. Keep up the great work :) Best regards, Kevin

Life Lessons with Dieter Lange I’ve almost completed Dieter Lange’s School of Life, and I’m very grateful that I decided to take it. Over the past 6 months, I’ve learned an incredible amount about myself. The videos, reflection questions, and accompanying texts are very well coordinated. Plus, the Greator team is incredibly helpful and very flexible when it comes to setting up payment arrangements.

I attended the Greator Festival 2025 and am still thrilled by the unique atmosphere, the inspiring talks, and the flawless organization. From the very beginning, it was clear that genuine transformation was at the heart of the event—both on a personal and professional level. I was particularly impressed by how the speakers and the entire event team managed to convey a sense of positive energy and motivation that continues to resonate long after the event. After the festival, I still had a question about a specific topic that had been on my mind. The Greator support team responded in no time at all; they were extremely friendly and resolved my issue not only quickly but also competently and empathetically. That’s exactly how I picture excellent service: personal, straightforward, and solution-oriented. Overall, the Greator Festival was an extraordinary experience for me—one that opened up new perspectives and inspired me in a lasting way. I can wholeheartedly recommend the festival and the entire Greator team to anyone seeking personal growth and genuine inspiration. I’m definitely giving it 5 out of 5 stars—and a huge thank you to the entire team for this valuable experience.

This is my third time at Greator this year. Great people, excellent topics for personal development and growth, wonderful conversations, and a superbly organized Greator team. They jump right in to help when problems arise and are super friendly. Thank you to everyone who puts together such an amazing Greator festival. I learn more and grow every time I attend, and I can recommend it to anyone who feels like they’re stuck in a rut and wants to change but doesn’t know how—you’ll find the answers at the Greator festival. See you at Greator!

The training courses with Christina & Walter have been the most valuable investment of my life so far. Since then, so much has become clearer and easier. Even after four days, the Live Coaching Days in Cologne still have a positive afterglow. It was so valuable to experience the two of them coaching in person. The highlight for me was the visioning session with so many other people who radiated positive energy. Thank you!

Last year, I had the privilege of participating in the Greator coaching training program—a clear, honest, and at the same time deeply liberating journey of self-discovery. This training was my school of life. A big thank you to Dieter Lange: His razor-sharp clarity regularly prompted me to reflect—and, above all, to take action. Being able to learn from him was a gift that has transformed me on many levels. But I’d also like to thank the entire team—because without you, this journey wouldn’t have been possible at this level of quality. You’ve done so much behind the scenes—moving things forward, organizing, and making it all possible. With a tangible impact. Thanks to Stefan, who introduced me to this "school of life" during a pivotal conversation. Thank you to Daniel, who was always there when technology suddenly became a hurdle. Thank you to the head coaches Silke, Melanie, and Reinhard, who guided me with expertise, heart, and reliability. And last but not least: My thanks to Christina and Walter Hommelsheim. Your Rauhnächte in December 2023 were the beginning. Thank you for this special time. Thank you for your work. “I came to learn and left to live.”

Greator is not just a company but an institution dedicated to transforming lives. I’ve had the privilege of meeting so many incredibly self-aware, fantastic, and wonderful people here—people I could never have imagined before. Furthermore, the Momentum training is such a profound, revolutionary process (in a positive sense) that I myself am currently taking a huge leap in my personal growth—one that deeply moves and touches me. For me—and I can only speak for myself :)—Momentum is something like the "Holy Grail" of personal development.

An incredibly compassionate, unbelievably warm-hearted, and highly motivating coach. The course content is well-structured, and you set your own pace. I highly recommend it to anyone who wants to understand life and themselves 🍀 Greator, as an educational center, is a true asset to this world. Great people, great training programs, and a great concept that empowers people to surpass their own limits.

After many years of absence, Greator managed to bring Tony Robbins to Germany for the immersive 50-hour seminar „Unleash the Power Within.“ It was clear to me that I absolutely had to be there. And it was more than worth it. Walking on hot coals gave me the confidence to master things that seem impossible. I became fully aware of the interplay between body and mind during a partner exercise on „body language.“ My personal highlight was „Transformation Day.“ Together with 14,000 other people, I was able to identify, dissolve, and redefine three of my limiting beliefs. I’ll definitely be back next year!

I’m so grateful to you for organizing Tony Robbins’ UPW 😍 I’d been dreaming of attending this live event for more than 10 years, and finally my dream came true! Even right after the training and now that I’m back home, I still feel an incredible surge of energy, and I’m channeling it into my projects with love for others. 1) I’ve created my own women’s community—something I’d been putting off for months. 2) I’ve shared the most valuable insights and tools I took away from Tony’s UPW. 3) I’ve recorded and released my version of Tony’s priming in my own language, and it’s absolutely amazing! Everyone who’s tried it at least once has told me about rivers of tears of joy and a powerful energy boost that lasted all day! I’m so happy I was able to share all of that! 4) Now I’m running a new project and serving others, helping them reach their goals more easily, and getting ready to launch my best educational course soon! I’m still amazed at how well-organized everything was. The only suggestion I’d make: please have fewer “cheat meals” in the food court and more healthy options, please❤️🙏🏼 Because I’d love to come back again next year!😉

For me, this training program and the decision it involved—to do something for myself—was the best decision of my life!!! I got to get to know myself, learn a lot about myself, others, and our behavioral patterns. The instructors are incredibly good! Simply the best! I love how well-structured the online program is and how affordable it is! The in-person seminars were also exceptionally well-done and organized. Greator did a fantastic job organizing everything—huge praise to them, and a big thank you for everything you do!!!

I’ve been doing the Greator Life Coach program for 2.5 months now, and I’m thrilled with it from start to finish. It took me a few days to get my bearings on the platform, and I got to practice putting myself out there, contributing, and becoming visible. Now that I’ve cleared that hurdle, the training has been a true gift! It’s the greatest gift I’ve ever given myself—it feels so good and brings me completely back to myself! Christina and Walter take great care to ensure that this training isn’t just another item on my to-do list or a source of stress in my life—and thanks to their help and reminders, I’ve been able to fully achieve that! The meditations are truly life-changing, and thanks to the videos, things often click into place! The “Lying Eight” is primarily about our emotions. I’ve been passionately engaged in personal development and psychology for over 20 years. However, there were often moments when I understood something on a purely cognitive level, but my emotions spoke a completely different language. I knew why I was angry. Yet I didn’t know what to do with that feeling. Thanks to this training, that bridge is finally there. I have much greater access to my emotions again, allowing me to be even more authentic and loving toward myself. I no longer have to push them away out of fear; instead, I’m learning to embrace them. And this has given rise to a sense of well-being that I wouldn’t want to be without!!! Through the community, I’m also getting to know so many wonderful people right now. Gone are the days when I felt like I was alone in my desire to make the most of my life. I used to only find others like me in podcasts and on YouTube. Now I’m getting to know more and more genuine, lovable, open-minded, and mindful people, and it’s simply a blessing. I would make the decision to take this training over and over again!!!! Thank you, thank you, thank you to Christina and Walter and the entire Greator team! You guys are priceless!!!!!

I spent a long time looking for a training program that would perfectly complement my independence in a holistic sense, and I found exactly what I was looking for at GREATOR with the Life Coach program. Christina and Walter’s knowledge is incredibly extensive, and you can really take away a lot for yourself—and especially for your future clients. The “Lying Eight” method offers an intensive and empathetic approach to gently releasing stuck blockages and positively transforming the initial situation. The only major downside for Austria is that our (not-so-dear) government doesn’t recognize this training, which means it can’t be practiced as part of a self-employed business under the “Life and Social Counselor” trade classification—which is a real shame, since, in my opinion, absolutely no other training program in Austria even comes close to this one. Even though I’m not allowed to coach with this training here, it still enriches the rest of my work in many ways, and for that reason alone, it was totally worth it for me.

The School of Life is one of the most fantastic ways to grow personally! Through many of his perspectives, Dieter has helped me further refine my ability to see life through a different lens—one that leads to greater serenity, wisdom, and contentment! His uncompromising approach to taking responsibility for one’s own life goes a long way toward helping us understand and grasp what freedom truly means. The School of Life was a gift to me that more than exceeded my expectations.

Dieter Lange - The School of Life. For me, Dieter Lange’s School of Life is both a source of validation and motivation for my self-awareness and my ability to lead myself. All of the content—and the "how," as Dieter Lange explains and demonstrates—is an immense enrichment for my life and my personal growth.

The Greator Life Coach Training Program is absolutely fantastic—not only in terms of content but also in terms of structure. The training material is superbly organized, follows a clear logical flow, and is thoroughly engaging. The way the coaching methods and techniques are taught is also excellent. It’s a great mix of "learning" the material, meditations, and exercises. There are wonderful opportunities to interact with Greator and other training participants. I’ve rarely learned so much about myself, tried so many new things, and stepped further and further out of my comfort zone. I’ve learned to give my feelings space, to let them be there, and to feel them through. Uncovering old beliefs, dissolving emotional blockages, connecting with my inner child, and making new decisions are just a few of the wonderful gifts I’ve been able to give myself through this training. And being able to pass all of this on as a coach is a truly wonderful feeling. Going through this training was one of the best decisions of my life!

When I started my life coach training in the second round in November 2020, I didn’t yet know how intense and profound the journey would be. I’m so grateful for this opportunity and my Stone group. For me, the best part of the training has been first exploring my own issues so that, as a coach, I can truly understand what I’m talking about. That’s what feels authentic to me. I highly recommend that everyone at least complete the Practitioner level.

Great program, amazing opportunities—but only for those who can afford to pay or secure financing for training programs costing between 10,000 and 34,000 euros. Talented individuals who want to apply to prove their skills right off the bat don’t stand a chance. You can only get into Speaker Night if you accept the terms and conditions of the training program. It’s a shame, because I think Greator offers unique opportunities.

Greator is simply a great company. Through their events and their work—both online and offline—they put personal growth front and center. Through their efforts, they broaden the horizons of tens of thousands of people—and likely many more than that. Once you’ve experienced events and training sessions with Greator, your life will never be the same. When companies like Greator establish themselves in our economy, humanity has a wonderful future ahead. Thank you for the Greator Festival 2022—it was unforgettable. All the best, Stefan

Behind Greator is a passionate team of experts from countless fields, all of whom share a common vision: to guide people on their journey to their true selves.
