what when why® – our formula for success:
Emotion Engineering

The fact that our name consists of a series of questions is a statement in itself. When you come to us, we ask plenty of questions and listen to your answers attentively – we immerse ourselves in your company’s strategy and your current task.

This gives us an in-depth understanding of your language, culture and communication goals – and we can then develop communication concepts that allow the emotional and factual dimensions to merge into one. We call this Emotion Engineering.



Live, Online or Hybrid Events: Reaching people means reaching goals.

Since Covid-19 at the latest, the requirements for tangible communication have changed!

Live events with their outstanding charisma are complemented by location-independent event formats such as online and hybrid events. That is also a good thing. Because strategic event marketing is and remains a long-term and continuous communication process, which is now also extended online.

Whether live or online events: With our event and communication concepts we activate and involve people in a sustainable way. The participants are an important and active part of the event. They help shape the entire communication process – and thus participate in the success story that is then written together.

The best way
to convince is
to demonstrate.

The mix makes the difference.
Our clients.
