Friends say nice things about us

"They have expertise, experience, commitment, and flexibility."

They have a crystal clear approach and presentation in a tailored program. Our time working with them created the proper public awareness through which we could achieve the necessary cultural changes, which then cascaded throughout our organization. They have expertise, experience commitment and flexibility in their approach.

"PostNL has gained in flexibility and speed of action."

With the cognizance of and passion for corporate effectuation our new division of Logistic Solutions, PostNL, was made eager to turn our gaze outwards for more entrepreneurial spirit. We're faster than before when working with others, dare to put down new concepts, and have gained flexibility and speed of action.

"One of the best programs at 3M"

In his 24 hour non-stop Hackathon and accompanying 100 days Effectuation Accelerator Thomas provided us with a truly hands-on and energizing experience to create new business proposition and building entrepreneurial capabilities. It has been quite a journey and I can honestly say one of the best programs offered to me at 3M!

"More than interesting mental framework."

"Effectuation Academy provided a more than interesting mental framework introducing their method to our Jong Management meeting at Euronext, Amsterdam. With sharp insights and recognizable examples we were presented with a more entrepreneurial business mentality. For me a very effective eye opener and a new way to fresh business opportunities… one step at a time."

"Impressive, intense, engaging, intimate and challenging."

“We got fantastic insight while we were challenged to introspect with great intensity and bare honesty. I have never been in a room full of scientists lost for words before. Impressive, intense, engaging, intimate, challenging in an unexpected way, awakening raw instincts, self-reflecting and self-realizing!”

"Most inspiring and entertaining"

"I met Thomas during the Intrapreneurship Conference 2014 in Eindhoven, The Netherlands. His presentation was the most inspiring and entertaining at the conference and I took away many important points about Corporate Effectuation. In 2015, I invited Thomas to give a lecture on Corporate Effectuation in my course on Corporate Entrepreneurship at TU Eindhoven. True to form, all 300 students gave him an average 9 of 10 points!"
