Professional Capital was founded by emeritus professor Willem Verbeke and Maarten Colijn. Both share a passion for sales and see this as a true art form. The fascination does not only lay in the way the human brain work, but also in the way of teaching sales techniques effectively. Together they developed a unique and effective training program.
Transferring knowledge and coaching the right commercial mindset to the trainees is the strength of Professional Capital.


Since the founding in 2004, Professional Capital has made the conscious choice to specialize in bringing change to a sales team. Professional Capital does this by looking at the total package. In a dynamic environment where trends and developments rise quickly, we think it is important to grow with it. Traditional theories are modified into a modern training approach. Key points are personal guidance, a down-to-earth mentality and a practical and direct attitude. The trainings are given with great enthusiasm, because we really believe that well-trained salespeople can really make a difference. Even if you don’t have a commercial background.

The rapid growth of the Professional Capital did not go unnoticed and resulted in the award as the fastest growing training agency in the field of sales and account management (FD Gazelle Award 2010, 2011, 2012, 2018 en 2019). Professional Capital has already trained more than 10,000 people from the Netherlands, Belgium and the rest of Europe and is known as one of the best training agencies.

We hope to meet you and your sales team! Let us make a commitment together.
