Willem Vermaak

Trainer

Willem is a Product Management trainer with a passion for leadership and creating the highest possible valuable product. These two passions come to life in everything revolving around product management, product leadership, product strategy, and product ownership.

He is a Professional Scrum Trainer for Scrum.org and is on a mission to help companies figure out their value potential and maximize the outcomes for their customers. 

As a previous Armed Forces officer and a voluntary firefighter, Willem has his roots in leadership. As a Product Owner, Studio Lead, consultant, and trainer, Willem has become passionate about validating and solving the problems and challenges of customers.

Helping companies to learn from customers very quickly and adapt to their feedback while improving their product management capabilities is what makes his world go round. 

To share his passion and knowledge of product management, Willem is also a keynote speaker at events. And to claim a bit of eternal fame, he co-wrote the book “Master the art of NO“, together with colleague and friend Robbin Schuurman.
