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.

At the same time, the demand for emotionalising media is also increasing. Together with our media partner PIXELSCHICKERIA, we offer creative overall solutions with a “goose bump factor”.

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.
