Hul le Kes

The Hul le Kes team is working together in a unique and self-developed way based on the complexity theory and non-Western philosophies. Within the company personal interests and paradigms of all people, involved in its circular business, are leading. Its non-hierarchical way of working provides space for personal growth of each individual. Intrinsic motivations from its owners, employees and clients are the key of the Hul le Kes business. On this page you will find the personal stories of Sjaak Hullekes, Sebastiaan Kramer and our other team members.

Sjaak Hullekes

Sjaak (1981) grew up in the safe and unhurried environment of one of the islands in the Dutch province of Zeeland. During his youth in the picturesque town of Zierikzee he developed a high interest in people, art, fashion and design. As a child Sjaak wanted to become an antiquarian, and his fascination for old and used materials has never disappeared (as you can see within the Hul le Kes collections). At the end he chose to start a study to become a Social Worker where he already started to connect creativity to caretaking. Meanwhile his interest in fashion kept growing. After he finished study as a Social Worker he started his study of fashion design at ArtEZ University of Art, Arnhem. During his study to become a fashion designer Sjaak continued working as a social worker.

In 2005 he graduated (Cum Laude) from the fashion department in Arnhem and made the first steps to become an entrepreneur together with Sebastiaan Kramer. He has been an entrepreneur since and has been working as a designer, teacher and coach. Sjaak has often been seen on Dutch television as a fashion designer, for example in the tv program ‘Genaaid’ where he took the role of coaching young designers about slow fashion principles.

Sjaak’s personal interests are connected to transience, peace and love. He is driven by his intrinsic approach towards people and products. He is inspired and intrigued by the beauty of their imperfections. 

As a co-founder and co-owner of Hul le Kes Sjaak is responsible for the creative direction of the company. Sjaak is ‘the face’ of the company, takes care of the daily activities at the Manufacturing Studio and Recovery Studio, and is Hul le Kes’ main designer and stylist.

Sebastiaan Kramer

Sebastiaan (1985) comes from a close-knit family in which creativity, freedom of expression and equality have been important values. His father taught him to take nature as an inspiration towards creative thinking. His mother taught about how every person has its own way of working and learning. He became interested in fashion at a young age and got accepted at the fashion department of ArtEZ University of Arts at the age of 15. 

After his Cum Laude graduation Sjaak and Sebastiaan started their own business. From that moment on Sebastiaan has been working as a freelance designer for many commercial brands. With his experience in the fast fashion industry he quickly started to see the flaws of the industry. During his career he started to develop an interest in designing strategies and alternative systems.

To combine his creative skills with his passion for new business models he started his study of business administration and management. He did research in the field of alternative ways to manage businesses. He specialized himself in the management of creative, innovative and circular businesses by using aspects from the complexity theory, non-Western philosophies and natural behavior of human beings.

Within Hul le Kes Sebastiaan works on the long-term perspectives and makes sure of positive dynamics within the company, aligned to movements in society. Besides that he is responsible for the business network, general management and finance. Sebastiaan coaches other creative businesses in finding their strengths and strategies. He is also a guest lecturer at universities to talk about alternative business management.

our assistant makers


At our Manufacturing Studio we work with interns from all over the country, and often also from abroad. Our studio is specialized in working with students and provides special learning programs for students from Rijn IJssel (vocational education). Hul le Kes also has internships available in other disciplines within the company. Design students, students from MA’s or marketing students are all part of our team. To apply for an internship send us an email.


Throughout the whole company we educate and work together with people with a, so called, distance to the labor market. Within our Manufacturing Studio this means most often that we help people with a refugee background in integrating in the Dutch culture and working habits. Te (re)integrating people at our Manufacturing Studio often already have their experience in working in the fashion industry in their country of origin.

internships at the Hul le Kes Manufacturing Studio

our Recovery makers


People with mental or psychological problems recover themselves and textiles at the Hul le Kes Recovery Studio. Depressions, burn-outs, anxiety disorders, extreme loneliness and other mental issues are growing in our society. We think this is not the problem of those people, its a problem of our society’s way of working. At the Recovery Studio they help recovering textiles for Hul le Kes and our wearers, while they are able to recover themselves.


We also work with volunteers at the Recovery Studio. In some cases these volunteers are in a burn-out situation themselves, in other cases our volunteers just like to support our social mission. Also at the Recovery Studio internships are a possibility to learn about the combination of social work and creativity.

Public Relations

Since the very beginning of Hul le Kes we have worked together with the Amsterdam based agency Spice PR for our Dutch public relations and press. Indy, Froukje and Davy have been a great support to our team since. More information for press can be found on our website’s Press Page.

Suppliers & Retailers

To Hul le Kes our suppliers and retailers are part of our team, as much as anyone else mentioned. And that is a huge difference between us and fast fashion companies who will always try to get more for (much) less. We like to think with our suppliers to make sure both our needs will be answered the right way. Sympany, 2Switch and others are part of our team of suppliers.


Sebastiaan Kramer is your contact for all wholesale enquiries. Please contact Sebastiaan in case you have any questions.


You as a wearer are another important part of our team. Again this is a totally different approach towards a consumer than you’ll know from the fast fashion industry. But we think we can only make a positive difference when our wearers are part of our way of working. We are always looking for your input in terms of our products or services. Please give us a call or email.
