About us

The WeMaCo team introduces itself

We want to shape the future through urban and personal transformation

For us, a liveable, sustainable city means that all living beings have a healthy, beautiful and safe environment. Therein exists a natural abundance within the planetary boundaries. The city of the future is a regenerative ecosystem – as lively and creative as a primeval forest. People love themselves, really live their lives and are deeply connected to their fellow world.

This vision motivates us in our daily work and forms the basis of our mission. Our team works towards such a world in a value-based way, together with our strong partners.

Our mission & our values

Who wants to change something, has to dare to do something. Therefore, a clear mission and a precise idea of one’s own values are needed.

Empathetic, creative & visionary

Empathic, creative and visionary, we support urban design actors in the development and implementation of holistic sustainability strategies, including participation processes/citizen participation.

Positive mindset

In coaching, we develop a positive mindset, emotional and mental strength, as well as awareness in dealing with the major challenges, especially in the sectors of sustainability, environmental, nature and climate protection, as well as in the social sector.


WerteManagement (German for ValuesManagement) describes our principle of values-based management both of our own person and with responsible action for the environment. In doing so, sustainable, open, honest, trustworthy, responsible and courageous corporate practice and cooperation are central to us.
