We see with our eyes, we feel with our hearts, and we do with our hands. And then, to make sense of everything we see, feel and do, we think with our minds. We teach so that our minds remain nimble. And humble. We always strive to have one foot in academia, whether it’s Erik and Froukje teaching one day per week at TU Delft, Erik teaching at Cedim Mexico, Eurib Rotterdam or HSL in Luzern, or Fred teaching at the Hogeschool Utrecht. Our students keep us sharp and focused. And we love helping our clients get in touch with them.

We believe that when we share knowledge, insights and experience, we multiply it. That’s why we love to help our clients not only apply what we uncover for them, but also uncover it themselves. We provide in-company training on topics varying from gathering user insights and applying design thinking to customer journey mapping and persona validation. Get in touch to learn about the training modules we have in store for you, or about the possibilities to craft a customized program just for you!


Sometimes, one needs to draw back, find a quiet place, and organize one’s thoughts. And then capture the fruits of that labour for prosperity. Writing is a way to cleanse the soul, to build expertise, to exchange knowledge and to progress the field. Here’s a list of publications and places where you can find our writing in books, magazines, and websites!


We regularly speak at conferences and events to test our vision and ideas and to share our learnings with the communities we respect and belong to. Drop us a line if you wish to inquire about speaking engagements. Here’s an overview of presentation we held in the past. Watch the news for regular updates on upcoming presentations.

Design the new business

In the summer of 2011, we cherry picked 6 of the best TU Delft Strategic Design students and offered them a summer internship. Their mission: to create a documentary on the state of affairs of Design Thinking, as it was applied in businesses across the world. The students took up the challenge with admiring verve (and innocence) and went to work. The result is Design the new Business, a project that comprises a 38 minute documentary, a workshop toolkit, an on going online debate and a world tour of screenings and workshops at leading businesses, universities and agencies. Check it out here and join the discussion.


7daysinmylife is an online qualitative research tool. It provides deep and rich insights in your customers needs and motivations. These insights help you develop better products, services or brands that really make a difference. The tool is based on Context Mapping, a research methodology developed at Delft University of Technology by Prof. PJ Stappers and F. Sleeswijk Visser.
7daysinmylife has the form of an online diary, which participants fill out during 7 days. During these 7 days, they keep track of what they do, what they think, what they dream of and how your product, service or brand has a role in their lives. The diary has an open character. This means that participants are free to answer the questions in the diary how they want. They can make use of (digital) post-its, pictures and icons, in order to make the diary really personal.
Are you interested in a 7daysinmylife project? Please contact us for further information. Ebay, DeltaLloyd, Mexx, Fatboy, Virgin, and Europcar have successfully used the tool.

designXchange business club

In an informal, business club setting, Zilver and Design Management Netwerk Nederland have initiated an exchange between thought leaders in change and business design. The kick off event in Essen was a huge success. The next event will be hosted by SAP in Heidelberg. Invitation only.

In a complex force field of stakeholders and interests, initiators of change must be able to creatively initiate and snowball positive change. They must bring to life relevant solutions that are good for business, customers and society. In essence, these people are challenged with designing tomorrow’s businesses.
In fact, the processes, methods, tools, and underlying mind-sets that these business shifts require, resemble the processes, methods, tools, and underlying mind-sets that the design profession has been developing over the last decade. In a sense the design profession is shifting towards a role of initiating change. And design professionals are developing traits that they share with many modern business leaders.
