“I am annoyed by superficial solutions and want to go into depth with you. Intuition and analysis broaden the horizon. I lead change in the public field, crossing silos in the process”

First and foremost, we work as partners: you as the person with the final responsibility for a task, me as a temporary pillar of support, sounding board and, where necessary, a louse in the fur. But together also means that we work with the partners involved. We move away from the silo or the rake. For a contribution to a larger social whole, we put the whole puzzle together and look beyond our own pieces. In the connection we find the energy and creativity needed to bring intentions to life.

Skilled in complexity

In a rapidly changing complex world, you won’t get there with reason alone. A prediction you make today will no longer be valid tomorrow. Exerting influence or achieving a result therefore requires more. Learning to act and discovering levers to turn the situation around. Daring to deviate from the beaten (or predetermined) path. We therefore use – in addition to analysis – methods that are grafted onto systems thinking. We make room for research into what works.


Broad Horizon

What do we not see when we look at an issue, its context and our own actions? Working with Emergentia is an adventure in which we discover more and more about the stratification of reality. We alternate between different perspectives: looking at the goal, broadening the horizon and diving into the deep end. Curiosity allows for new connections, insight and movement.
