James Holder founded the fashion retailer Superdry with Julian Dunkerton.
Holder and Dunkerton developed the brand that became Superdry by combining Japanese-inspired graphics and styling with American vintage influences and British retail presentation. Holder brought experience in design, branding and product development, while Dunkerton had built retail expertise through earlier clothing businesses.
Superdry grew from a comparatively small fashion operation into an international clothing company with stores and wholesale distribution in multiple countries. Its distinctive logo-heavy clothing and jackets became central to the brand's identity during its rapid expansion.
James Holder later appeared as a Dragon's Den investor. He is sometimes confused with Julian Dunkerton because both men were fundamental to Superdry's development, but Holder was the co-founder associated with the brand's design and product side.
