Who We Are

Like the Sherpas who help Himalayan climbers during their quest by providing deep knowledge and an understanding of the terrain, routes and weather conditions, all of which maximize the chances of reaching the summit, our coaches advise, enable and assist our clients who are on missions of their own.

The teams and organizations we work with, just like the expeditions, must put in the effort, take on challenges and face the risks involved in reaching their goal. Our purpose is to assist them on their journey towards maximum results.

In order to achieve higher levels of productivity, our clients aim to sustainably and quickly deliver value and innovation by creating learning organizations. With our deep knowledge of lean and agile thinking and organizational tools, we provide guidance and support to reach higher heights.

How we work

We have a comprehensive and proven approach to guiding organizations and individuals to achieving three results: stronger performance, more productive working relationships, and greater individual well-being.


Our coaching approach rests on two pillars: Systems Thinking and Servant Leadership. Systems Thinking is a conceptual framework, a body of knowledge and a set of thinking tools to help recognize system dynamics, mental models and uncover local optimizations over system optimizations.


Instead of seeing problems as caused by someone or something “out there” and solely reacting to these, it helps to see the bigger picture and how our own actions create the problems we experience. This creates a mindset shift that makes up the core of a learning organization.


We believe that Servant Leadership in combination with Skilled Facilitation is key to introducing a new way of thinking and operating in an enterprise. With our coaching services, we empower both formal and informal leaders, so that, through their own behavior, they help their team evolve into a performing unit that meets the expectations of its clients, becomes better over time, and contributes positively to the personal learning and well-being of its members.


Our coaches do this by creating and maintaining the conditions that allow individuals to move into the desired direction with clarity, a good structure, an enabling context, and competent coaching. On top of that, our coaches apply a compassionate method for more effective team facilitation based on the Mutual Learning approach.
