Our values

We don’t aim to become the largest agency, but rather the best. That’s why we rely on clear values:

Wortspiel Values


Cooperation can only work well if we’re aligned on a personal level. We value honesty, humility and authenticity.


Trust is more important to us than contracts. As long as both parties are happy and continue to evolve together, we will keep working together. If this changes we will part ways.


The marketing landscape is changing so fast that long-term top performance is only possible with a high degree of specialisation. We prefer to do less and do it as well as possible.


Here you can see our latest blogposts. In the blog history you will find all previous posts.


We are happy to share our experience at conferences and universities. Here are the next speeches and courses with our participation – you can find a complete list in our calendar of events:
