In Dutch SLIM means Bright | Clever | Smart and Intelligent.

We design intelligent IoT products and smart mechanics and do this with a lean integrated development process and minimal overhead. Our aim is to simplify the product we design to its bare essentials, create meaningful projects and we strive to push the boundaries in design and technology.


We see ourselves as an external development department for our clients. And by making sure we create real added value, we build long relationships. We are happy with the design and innovation awards but for us the clients appreciation of our work is key.

The SLIMDESIGN design team specializes in Design, Mechanical and Electrical Engineering. Complex projects (like IoT) need experts from a large variety of disciplines. For each project we built a core team that remains with the project from start to finish and use an integrated process where all aspects (Design, ME and EE) are developed simultaneously. In this way there is fluid communication, no loss of information and late changes are easier to handle. For the other disciplines we have selected partners that have similar flexibility and drive for perfection. This way we are flexible and can make sure we work with the best experts in their field.

The right production partner has to have the expertise to be able to deliver the requested quality for the right price.
