What some of our leaders say about us

Jeroen Brouwers Head of Product @ Vesper

Being part of the Group Effort peer group is incredibly valuable. It provides a platform for exchanging ideas, best practices and learnings with people in the same position.

Gijs Hendrix VP of Product @ Convious

As the most senior product person in my organisation, it's very hard to get useful feedback. This is what the Group Effort peer group provides me, as well as opportunities to get challenged and grow. It's been incredibly valuable.

Miranda Ippel Head of Product @ Twelve

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.

Arco Westbroek CPO @ Carerix

It's very useful to share knowledge and be challenged by people in the same role within other companies. It's also fun to only need half a sentence to understand each other and have a relevant conversation.

Tom van der Woude Head of Product

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.

Jelle Kamsma Head of Product @ ANP

Martijn is an excellent facilitator who always has a metaphor or story at hand to help you reframe your thinking.

Sjoerd van den Biggelaar Product Owner @ Eurofiber

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.

Peter Deumer Director of Software Development

As a coach, Martyn managed to provide a mirror instead of advice. Based on what I saw in that mirror I managed to identify certain aspects of myself, both personal and business, that I wanted to work on. I very much liked his approach towards sustainable improvement.

The Value of Perspective

If you want to improve your leadership, we are here to help. Our expertise is helping top level management get most out of themselves and their teams.

How does it work?

Depending on your needs, we offer 3 different services for improving leadership:

Peer Groups

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”.

**Peer groups are on a invite only basis**

Executive (team) Coaching

Sometimes, you are working on something that is better tackled alone (or with your team).

With our proven strategies we help executives grow past their own barriers and help them and their teams achieve better results. Our philosophy of coaching is: Measurable results, in reasonable time.

In-person coaching is available only in London, Berlin, and the Netherlands. We commit to results and hope you do too. If you’re curious, please email us about our intake procedure.

Search & Recruitment

Group Effort has a strong network of over 5.000 Product, Tech & Operational leaders in Amsterdam, Berlin & London.
Add to this that we work with over a hundred experienced leaders in our peer groups, making it easy for us to find and get access to your ideal candidate.

We have a process that not only includes finding candidates with the right skills, but also takes your company culture into account.

What does it look like?

Coaching is always tailor made. The intake is always on location in either Hilversum or Berlin.

After forming a solid coaching question, it is determined how many sessions are needed to achieve this. We have a 100% success guarantee.

Over the course of a year you meet up with your group of experts under the guidance of an experienced coach.

Together you break bread, tackle challenging cases and discuss developments in your industry that affect you all.

Current OPEN peer groups

CEOs

To keep the company growing, you have to keep growing yourself. One of the biggest dangers is that you might develop blind-spots on the way. These groups give you perspective.

COOs

Being a COO is a very special role. Your company grows, and as it does it requires you to grow with it. The different growth stages require different things from you. We match you with COOs that are in comparable growth stages.

Product Leadership

It is lonely at the top of product. Whether you're a CPO, VP of Product, Director of Product or a Heads of Product. We have a group that can add new perspectives to your challenges.

Technical Leadership

We Provide different groups for CTO, VPs of Engineering, Directors of Engineering etc. We separate physical product, physical&software and software groups to make context more alike.

CFOs

Being end responsible for the financials brings specific sets of challenges. From deciding when it is time for cut-backs, to working with that controller that has a black box of excel hell, to your role in the leadership team. There is always opportunity to grow.

And many more!

We are currently growing rapidly. We added partner coaches and they are reaching out to people close to their expertise. Aside from the ones showcased here, you might be approached by one of our partner coaches for a group that serves your specific niche. Have fun!
