Testimonial Marriott Hotels International Karim Rache

Karim Rached Project Director, Europe Finance / Marriott Hotels International

"We were all delighted with Ilja – his keynote address/speech was 'on point' and exactly what we were looking for. His 'change message' was easy to understand for our multi-cultural audience, delivered with good humor and self-deprecation – the attendees loved it! We particularly appreciated that he took time afterwards and made a real effort to connect with our delegates during breaks and meals for the rest of the day. From first contact, he was easy to work with and his preparation was immaculate, he worked seamlessly with our conference production company and was generally very easy to get along with – a very likeable individual with a good, positive and constructive message. Just what we'd been looking for!"

Initial restrained interest, coupled with a good portion of curiosity on the part of our management team, very quickly turned into great euphoria (according to the German dictionary Duden, a temporary overly cheerful and confident mood, high spirits, state of optimistic enthusiasm, intoxicatingly heightened exuberant feeling).

Testimonial Kelvion GmbH Tanja Günther

Tanja Günther, Head of Internal Consulting / Kelvion GmbH

It was simply amazing. Ilja didn't just give a keynote speech, but managed to transport the message of change with simple and relevant examples. He highly customized his content, and everybody in the audience felt how easy dealing with change can be. Everyone got the message that change is a choice we need to make. Every single day. He energised the room, and sometimes you could hear a needle drop. He was highly entertaining and was able to “get” everyone in the room: Americans, Chinese and the Europeans. He also did not hide the pitfalls in the "change process" and the fact that courage and willingness to take risks are also part of it; so not everything is always SIMPLE. The buzzer and the slogan "Oh yeah!" are as SIMPLE as they are powerful and made us feel that anything is possible if everyone just said yes, I want this! His personal experiences helped us to realize that CHANGE can become a personal roller coaster.


Claudia Bellanti, City of Iphofen Tourism/Culture/Economic Development/Sport

Ilja's presentation at our wine tourism symposium was exactly the right speaker at the right place at the right time. Many listeners have been gratefully shaken up after the long Corona break and, with his help, have shed their fear of change.

His words are still resonating in people's minds a few days later, and the fresh and amusing rhetoric provided the appropriate impetus. Many thanks for this!

We would like to thank you from the bottom of our hearts for the engaging keynote speech yesterday. You moved us deeply with your words and your presentation.

Your presentation was valuable, transported the right messages and suited the audience perfectly. You adapted your words individually to our topic "Team game - nobody wins alone!" and repeatedly made reference to AMBAU PS and the needs of our customers. The customers were just as enthusiastic as our team was. Our customers spoke of an "extreme enrichment for private and professional life", "consciously want to focus on new opportunities" and took many positive thoughts home with them. Colleagues and customers were infected by your passion. They were all inspired and spread the feeling of wanting to change something and to be braver, to question themselves.

Die Unternehmensphilosophie basiert auf unserem gesamten Denken, Handeln und Wirken. Unternehmen verändern sich, wenn die Menschen sich verändern. Deshalb glaube ich fest an zwei Dinge: An die Kraft der individuellen Persönlichkeit und die Magie einer von starken Werten getriebenen Veränderungskultur. Wenn sich die individuellen Bedürfnisse der einzelnen Menschen mit den übergeordneten Organisationszielen im Einklang befinden, entsteht ein magischer Cocktail aus Leidenschaft, Commitment und operativer Exzellenz. Dies haben wir in unserem Mission Statement zusammengefasst:

“Mein Businessansatz ist radikal menschlich, denn ich bin der festen Überzeugung, dass der Mensch in Zeiten der immer schneller werdenden Veränderung der wichtigste Erfolgsfaktor der Zukunft ist. Ich helfe Menschen dabei, ein auf Selbstbestimmung, persönlicher Freiheit und Sinnhaftigkeit basierendes Leben zu führen. Ich unterstütze Organisationen und Unternehmen, die großen Chancen der Veränderung zu nutzen und eine Change Kultur zu etablieren, die von geteilten Werten, Diversity und Sinn geprägt ist. Die individuelle Definition von Erfolg ist dabei der kraftvolle Fixstern, der Weg dort hin die Veränderung.”


Diese Werte treiben uns an
  • Verantwortung: Nur wenn jeder persönliche Verantwortung übernimmt, können wir gemeinsam erfolgreich sein.
  • Dankbarkeit: Wir gehen mit einer Attitude of Gratitude durchs Leben. Wir geben, bevor wir nehmen.
  • Diversity: Wir respektieren jeden Menschen so wie er ist und behandeln ihn individuell.
  • Integrität: Wir lassen Taten sprechen und tun, was wir angekündigt haben.
  • Unterstützung: Niemand gewinnt allein. Deshalb ist uns das Team heilig.
  • Familie: Erfolg hat bei uns eine klare Reihenfolge: Family First, dann kommt das Business.
  • Bedeutung: Für uns ist Job nicht nur Job. Unser gesamtes Wirken beruht auf Sinnhaftigkeit, um die Welt jeden Tag ein Stück besser zu machen.
  • Humor: Wir lachen gerne und viel, besonders über uns selbst. Denn für uns muss Arbeit vor allem eins: Spaß machen!
  • Qualität: Wir haben hohe Ansprüche an unsere Produkte, unseren Service, besonders aber an uns selbst.
Natürlich gibt es für uns auch einige NO-GO‘s:

Gleichgültigkeit. Beliebigkeit. Feigheit. Egoismus. Rumeierei. Zynismus. Humorlosigkeit. Schwarzmalerei. Gewalt. Hass. Dogmatismus. Besserwisserei. Opportunismus.


Diese Überzeugungen treiben uns an
  • Wir glauben, dass Unternehmen sich verändern, wenn die Menschen sich verändern.
  • Wir glauben, dass eine Kultur der Veränderung jede noch so ausgetüftelte Strategie schlägt.
  • Wir glauben, dass wir für unsere Ergebnisse verantwortlich sind. Für die guten, wie die schlechten.
  • Wir glauben, dass in jedem Problem eine Chance steckt.
  • Wir glauben, dass Motivation auf Sinnhaftigkeit und Werten basiert und nicht auf externen Faktoren.
  • Wir glauben, dass in jedem Menschen ein großes Feuer lodert, das nur darauf wartet, entzündet zu werden.
  • Wir glauben, dass sich alles verändert, wenn Sie sich verändern.
  • Wir glauben, dass innovatives Denken, harte Arbeit und Commitment die Grundlage für Erfolg bilden.
  • Wir glauben an Individualität und Diversity statt an Gleichmacherei.
  • Wir glauben an einfache Lösungen und nicht an komplizierte Probleme.
  • Wir glauben an Klarheit, Entschiedenheit und Integrität.
  • Wir glauben an Ergebnisse und nicht an Ankündigungen.
  • Wir glauben, dass der Umgang mit Veränderung die wichtigste Schlüsselkompetenz der Zukunft sein wird.

These beliefs drive us
  • We believe that companies change when people change.

  • We believe that we are responsible for our results. For the good and the bad.
  • We believe that in every problem lies an opportunity.
  • We believe that motivation is based on purpose and values and not on external factors.
  • We believe that in every human being there is a great fire just waiting to be ignited.
  • We believe that when you change, everything changes.
  • We believe that innovative thinking, hard work and commitment are the basis for success.
  • We believe in individuality and diversity instead of equality.
  • We believe in simple solutions and not complicated problems.

  • We believe in results, not announcements.

code of values

These values drive us
  • Responsibility: We can only be successful together if everyone takes personal responsibility.
  • Gratitude: We go through life with an attitude of gratitude. We give before we take.
  • Diversity: We respect everyone as they are and treat them individually.
  • Integrity: We act and do what we promise.
  • Support: Nobody wins alone. That’s why the team is sacred to us.
  • Family: Success has a clear sequence for us: family first, then the business.
  • Meaning: For us, a job is not just a job. Everything we do is based on meaningfulness in order to make the world a little bit better every day.
  • Humor: We like to laugh a lot, especially about ourselves. For us, work has to do one thing above all: be fun!
  • Quality: We have high demands on our products, our service, but especially on ourselves.
Of course there are also some NO-GO’s for us:

Indifference. arbitrariness. Cowardice. Egoism. bumbling. Cynicism. lack of humor black painting. Force. Hate. dogmatism. know-it-all. Opportunism.


corporate philosophy

The corporate philosophy is based on our entire thinking, acting and working. Businesses change when people change. That’s why I firmly believe in two things: the power of individual personality and the magic of a culture of change driven by strong values. When the individual needs of each person are in line with the overarching organizational goals, a magical cocktail of passion, commitment and operational excellence is created. We summarized this in our mission statement:

“My business approach is radically human, because I am firmly convinced that in times of ever faster change, people are the most important success factor for the future. I help people to lead a life based on self-determination, personal freedom and meaning. I support organizations and companies to seize the great opportunities of change and to establish a change culture characterized by shared values, diversity and meaning. The individual definition of success is the powerful fixed star, the way there is change.”
