JCK, headquartered in Quakenbrück, originated from a textile retail business that has been family‑owned since its foundation. Through organic and inorganic growth, the company has developed into one of Germany’s largest textile trading groups. With its highly successful private‑label business—accounting for around half of revenues—JCK acts as a full‑service provider for major retail groups. The group analyses market trends, designs textiles, organises production and ensures timely delivery to its customers. 

In recent years, JCK has also built up additional attractive business areas. Following the acquisition of several companies, the group now generates around 50% of its revenues from promotional products as well as sports and outdoor apparel. In these newly developed segments, JCK places a strong emphasis on the internet as a sales channel; for example, through its stake in 11teamsports, a rapidly growing online retailer specialising in football apparel and accessories.
