JSD knows the ins and outs and do’s and dont’s of product development. But we don’t believe in one fixed approach for every project. Therefore we carefully evaluate the needs of our clients at the start of our partnership. Based on this we offer a tailored approach, ranging from a single design that is further developed by our clients to a ‘full service’ approach. For our projects we work together with the best manufacturers in the Far East. Over the years we developed an excellent knowledge and experience in sourcing, prototyping, mass production, product management, quality control and the import and export of goods.
