We are helder-id.
We design and develop products and take care of realization.

“Helder-id is an entrepreneurial design & product development consultancy. Our team consists of well-trained, experienced, creative industrial designers & engineers. We have invested in a vast network of development & manufacturing partners. We design and develop products and we take care of realization.”

Our aim

At Helder-id we just love to create things. We are no-nonsense product developers, always aiming to find straightforward and effective solutions to complex problems. Whether in a limited series or mass production, the end product should always embody the perfect balance of functionality, appealing design and efficient manufacturability. In the end, we strive to deliver successful products that help our clients to achieve a durable competitive market position.


The helder-id team is very much used to working according to highly structured integral product development trajectories, but we always maintained the flexibility that is needed to create innovative solutions. The methodology described below is our guideline, but commonly we adapt to the specific needs of our clients. Working together, with both our clients and our development partners, is an integral part of our approach.
