In the peer group sessions, Martyn listens attentively, intervenes when the conversation veers off course, and frequently employs metaphors for clarification. He remembers the main themes from previous sessions for each individual, which deepens the conversations and advice. This is not only impressive but also extremely valuable for the participants.
The peergroups give me the opportunity to learn from the experiences of Heads of Products. I notice that more and more often I find myself in situations where I can apply what my peers have already experienced and learned and I can apply that knowledge to make judgment calls or prevent making mistakes that I would have probably made otherwise.
Every day, distractions come by that you can use as an excuse to neglect or postpone less enjoyable but more important matters. Martijn made me aware of the distractions of the day and the choices I was making unconsciously. He didn't do this by telling me what to do, but by skillfully coaching me in the right direction with questions and tools to help me understand the situation myself.
Imagine the insights you could gain from 7 experienced leaders in your field.
We form peer groups of 7 leaders with the comparable roles from similarly sized companies. These groups meet 7 times a year to structurally learn from each other to become (even) more effective leaders.
Segmentation is based on role and company size. Think “COOs of companies sized 200-500 people in London” or “CPO’s of SaaS companies sized 50-200 in Berlin”.

If you’re a product or tech leader done with fluffy talks, vague advice, and generic content overload — we might be a fit.
Over the past years, I’ve built a European community where sharp minds challenge each other to grow.
I’ve had the privilege of looking behind the curtain at 200+ companies across Europe, seeing what makes great leaders thrive (and where others fall short).
We bring those insights to you through curated peer groups, invite-only conferences, and tailored support like assessments, off-sites, and training — all built to help you grow faster by learning from those who’ve been there.

Sabina makes sure everything runs smoothly. Without her we would be hopelessly lost. She enables the success of the Group Effort by always creating order and handling communications and operations. She is a talent we are lucky to have, if she doesn’t already know how to do something she will learn it in minutes.
If you’re a client of a peer group you will see that communication goes through Sabina. Her mission is to make sure you get the best experience possible.
If you’re at one of our niche conferences she is the one who runs the show, and you can reach her with all your questions.
Oh, and did you know she worked at UN Women in the past? How cool is that.
Joeri’s role in the Group Effort Team is to reach out to specific groups of executives. He hopes one day to become a financial executive himself, and is using his time at Group Effort to get as much knowledge and skills as he can to prepare him.
Aside from outreach Joeri is always ready to help wherever he can. He combines his job with rowing at a national level.
