Superdry co-founder Julian Dunkerton is leaving the business later this week.
Dunkerton will step down from his role on 31 March to pursue other business and charity interests.
Dunkerton said: “I am immensely proud of everything achieved at Superdry over the past fifteen years. As a fast-growing, innovative business, Superdry has always evolved to ensure it keeps delivering.
“With other demands on my time it is the right point for me to transition my focus and responsibilities.”
Peter Bamford, chairman of Superdry, added: “With Superdry embarking on the next phase of its ambitious growth plans, and with other interests and opportunities available to him, Julian and I have been talking for some time about the right time for him to move on from the business.
“I have enjoyed working closely with him over the last eight years and, on behalf of the board, I would like to thank Julian for his outstanding contribution in building Superdry into such a great brand.”
Superdry, formerly known as SuperGroup, was formed in 1985 when Julian Dunkerton launched a store called Cult Clothing in Cheltenham with his business partner, which they subsequently turned into a nationwide chain.
In 2003, Dunkerton joined forces with Bench founder James Holder to create a new in-house brand, Superdry. Cult Clothing closed in 2012 after being gradually phased out of the business.
