Janneke helped me to recognize the mental patterns of my “Saboteurs” that were holding me back, like the Judge. She guided me in strengthening my “Sage” mindset, the calm, wise part of me that can respond thoughtfully instead of reacting. Through daily simple mental fitness exercises, I learned how to slow down, reframe challenges, and choose solutions grounded in empathy and clarity.

Beyond the original goals (improving my emotional resilience, communicating more clearly and augmenting my relationship with my business partner), I came away with a mental toolkit I can use for the rest of my life. I now know how to shift from stress and reactivity into a more grounded, Sage-driven state, something that has improved not only my work relationships but also my overall well-being.

I really valued Janneke’s intelligence, calm presence, and solution-focused approach. She blended the structure of Positive Intelligence with genuine empathy, making ideas and notions easy to apply. She created a space where I felt supported and challenged in the best way, and I left each session with both insight and practical steps forward.

Janneke has given me some tools that I can use for the rest of my life to deal with life and work challenges. She does not have a fixed agenda that she pushed on me during any of our coaching sessions but rather helped me identify the things that I needed. And most of all, I truly enjoyed the relationship that we were able to build over time. She is very personable and easy to talk to. I highly recommend Janneke!

If you’re considering working with Janneke, take the leap and get ready for positive changes in every aspect of your life!

Working with Janneke has been a life-changing experience. The theory of a growth mindset is key and hard to truly embrace. Having had the privilege to live the growth mindset and break old habits throughout our coaching has been key to creating a long-lasting impact.  While coaching with Janneke drastically increased my creative output and problem-solving capabilities. One immediate outcome is the design and development of an accessibility mouse that was successfully brought to market by Microsoft in 2023, supporting people with disabilities, including my own daughter Jara.

Coaching helped me in my transition from a full executive role to a ‘new life’ outside of the commercial business. This really helped me to think and decide about my ‘principles’ and what to do next … and not getting distracted by ego or other non-helpful forces. Lots of positive energy and a great experience.

Janneke’s deep listening, experience, and insights provided the guidance and support I needed to transform my goals into action and results, including the successful publication of my book Worthy. Janneke also gave me the confidence and nudge I needed to bring forward the best version of myself.

No topic was too odd for Janneke, allowing me to work on my struggles with my calendar, my presence in a meeting, the many ways I was betraying my messages with my body language, being vulnerable with others, and being there through two of the most difficult times in my life personally. I was amazed at the progress that we made together.

Perhaps her greatest strength is simply her ability to listen and not just listen but to hear  what you are saying.  Not just saying it back or acknowledging it but actively understanding how to take what you’ve learned and apply it to that moment.  This has been a time of great stress in my life both in work and beyond and Janneke was able to lead me through it and come out the other side. I truly enjoyed talking to her, uncovering insights and the coaching she was able to give me to navigate these very difficult times in my life successfully.

Working with Janneke was a privilege, and it was life-changing. After losing my wife to cancer, it became quickly important to find ways to approach life with a positive and hopeful outlook. Janneke was patient, kind and encouraging making sensitive discussions about personal strengths and shortcomings very approachable.  I learned tools to manage my mindset, that helped me to better approach life and work challenges.

What I enjoyed the most about working with Janneke is her focus on how to turn every situation and challenge into a positive outcome. I also liked her expertise on mindfulness and ideas for how to stay focused and present in stressful situations.

Working with Janneke helped me to grow as a leader on my growing team. She helped me to define processes and ways to think through some of the challenges that came up. I learned how to:

• Give and receive more meaningful feedback
• Make 1:1 meetings with team more productive
• Focus on incorporating my strengths into my work

Janneke helps you to bring your best self to work every day and be excited to be relied on, to help people and infuse passion into all of your interactions. Working with her gave me the courage to make some major changes I had been mulling in my work & personal life, including building the career I wanted.

After our coaching (including the Positive Intelligence Program) I felt stronger, more confident, and comfortable, and I realized what made me happy, and most effective. By incorporating more of my strengths at work, I enjoyed my work so much more and made more impact too. At the same time I created more time for other important things in my life, including taking care of myself, my family and friends.

Janneke is a gifted coach, and with ‘Positive Intelligence’ has a wonderful platform & tool to make very concrete steps forward with my professional and personal development. The beauty of PQ is that it gives concrete guidance on what to do every day. You do this for such a period that it becomes part of your life, a patch in your brain, supported by Janneke and the App. The methodology is 1 but Janneke makes it very tangible for me.

Janneke, is a very mature and inspiring coach, with a natural talent to find a balance between making you feel at ease while at the same time challenging your (hidden) aspirations.

Next to all her professional learnings as a certified coach, she brings in her own experience as a finance professional, who knows what it means to perform under pressure.

My personal experience to go through the Positive Intelligence training cycle as part of our coaching, has not only brought me insights in the saboteurs that stand in the way to optimally function as a professional, but also provided me with incredibly valuable tools that help me to perform better and support my colleagues, family and friends in multiple circumstances.

I wish anyone aiming to personally grow his/her skillset the joy of a coaching session with Janneke.

After more than 25 years leading teams in the tech industry, at the beginning of 2020 I found myself at a significant crossroads in my career. I was feeling “stuck” and plagued by self-doubt and self-judgment. Going through the Positive Intelligence program with Janneke alongside our 1:1 coaching sessions was invaluable in helping me build new skills to shift my energy to focus on what is possible. As a coach in training myself and with over a decade of experience working with coaches previously, Janneke’s approach alongside the Positive Intelligence program gave me entirely new, pragmatic and powerful tools that I would not have been able to develop on my own. My mindset has completely shifted from where it was a year ago, I have a ton more energy both in my job and with my coaching clients and my negative inner critic “chatter” has nearly disappeared. I couldn’t recommend her more strongly!

Janneke is a talented coach who enables her clients to achieve what they seek. She connects easily with most anyone, and is adept at asking questions that surface core issues in people’s lives. I was able to quickly progress on several stubborn issues with her help and would seek her out again.

Janneke’s leadership coaching benefitted several of my team members during a time of significant change and challenge. Their growth during her coaching was visible and they found it very energizing working with Janneke. Additionally, Janneke’s strength in coaching teams through the Positive Intelligence program benefitted me and my team. The program increased trust, gave the team a common language to describe stress and cope with it in a resilient way. I recommend this program to anyone interested in growing their mental fitness aka their ability to smoothly handle life and work challenges and changes.

Janneke is a dynamic coach who inspires those around her. I highly recommend Janneke for her exceptional coaching during the Positive Intelligence Program.  Her impact on our team was profound and valuable! Her facilitation skills fostered an engaging environment, encouraging participants to embrace a growth mindset. Her unique blend of business acumen and soft skills development significantly enhanced the experience of the Product and Technology Leadership team and my teams.

The Leadership team of Xbox Devices and their teams grew when working with Janneke. Despite the challenges of being fully remote, Janneke’s PQ coaching was able to drive significant impact. We learned how to use our mental & emotional energy more effectively. Participants felt like they became better at managing stress, handling relationship conflicts, coaching and inspiring others, which in turn resulted in improved collaborations and performance.

Janneke is a stellar coach. She led our 7-week team practice and Positive Intelligence team workshop for the Leadership & Culture organization at Pinterest. We are seeing improved team norms & trust, better alignment & productivity, and improved cross-functional collaboration. This supported us to lead transformation for the entire company.

Janneke is a fantastic coach and I appreciated that she designed a workshop bespoke for us. She managed to get everybody deeply engaged and open to her. As a team we now have a new language and style that has improved our collaboration and innovation.

My engineering team and the Product Manager team went through the Positive Intelligence program together with Janneke, and our teams worked far better together and gained a much better understanding and empathy for each other as a result of her ability to coach and guide us.  Having Janneke present, facilitating and guiding us took it to another level entirely.  Her empathy, understanding of how to apply the teaching, her leadership, her support was unmatched by any other person I have worked with throughout my entire career.

Janneke is a gifted coach, and with ‘Positive Intelligence’ has a wonderful platform & tool to make very concrete steps forward with my professional and personal development. The beauty of PQ is that it gives concrete guidance on what to do every day. You do this for such a period together with your team that it becomes part of your life, a patch in your brain, supported by Janneke and the App. The methodology is 1 but Janneke makes it very tangible for me. Not only for me but also for my colleagues who are super enthusiastic. They are happy & more effective, we speak the same language, and know how to help each other to beat out best. But a methodology is just a methodology and Janneke makes something beautiful out of it.

Janneke saved my sanity. I met her when a boss hired her for leadership team training. Her program was very impactful for the team, giving us an opportunity to get to know each other and a common language to use for dealingbwith issues. I personally got so much out of it I began working with Janneke 1:1. She helped me center myself, find myself, and navigate a tricky work situation. Her approach feels organic and so supportive. I felt safe to explore the things holding me back, while developing a better understandingof what makes me tick. The positive intelligence program really worked for me. Life threw me a big curveball while I was working with Jenneke. I lost my beloved wife of 25 years to cancer. With Janneke’s help, I was able to process the unthinkable so I could be fully present and a source of love and comfort for my wife. I went from being a generally anxious person, feeling frustrated with my job to someone who weathered some big storms and came out the other end feeling strong and whole. I can’t recommend Janneke enough and I am so thankful she was there at such crazy time in my life. I feel more comfortable with who I am, what I want out of life, more peaceful. I still practice the tools she taught me. She is professional but warm and easy to talk with. She changed my life for the better. She is amazing.

Working with Janneke over the past few years has been transformational. She helped me focus on my strengths, understand my saboteurs and sage, and grow as a coach and manager for others. Through the Positive Intelligence program, she equipped me with practical tools to recognize unhelpful patterns and shift toward clarity, empathy, and purpose. Her calm, wise presence, incisive questions, and actionable guidance made every session meaningful and moved me forward. Because of our work together, I’ve advanced my career by large steps and developed a more integrated perspective on my life and work. Janneke’s coaching has been genuinely career and life shaping.
