We humans have our own natural rhythms of stress and recovery, or action and rest. The closer we follow these personal biological patterns, the more energetic and productive we are likely to be.

It is Onewave’s expertise to let people discover their unique energy balance and give them science-based insights they can apply in everyday life. We believe that energized people create more positive impact!

Why we do what we do

How can you recharge after a peak performance, so that you remain energized at work and outside?

That’s what Lieke wondered when she was an HR advisor responsible for a group of consultants working under high pressure. From her master’s research at FC Groningen she knew that professional football players function best alternating high performance with serious time for the body to recover. Consultants were expected to excel as well, but were they able to recover sufficiently, both physically and mentally? And did they still have enough time and energy for life beside work?

In 2018, Lieke and Stijn started Onewave from the conviction that people can perform at a higher level without exhausting themselves or those close to them, if they learn to better manage their energy and if they are adequately facilitated to do so by the companies they work for. In 2019 Noortje completed the Founding team and stepped in as a business partner. Together, they combine in-depth understanding of HR strategies, business and stakeholder management with scientific expertise related to physiology, health, training, coaching and top sports.

Their ambition is to learn people how to be more energized in work and life.


Our core-team is compact and flexible, with a no-nonsense and involved mentality. We have a shared drive to show people and organizations how to structurally improve their energy level.

Our program is guaranteed to be innovative and scalable: besides our core-team of coaches, specialists and business developers, we have a variety of partnerships to provide our customers with state-of-the-art technology, expertise and guidance.
