Theo Paphitis founded the Theo Paphitis Retail Group, which brought together several retail and consumer brands associated with his business career.
Paphitis became prominent in British retail after acquiring and developing businesses including Ryman, the stationery retailer, and Robert Dyas, the hardware and household-goods chain. His commercial interests also extended to fashion and lingerie through brands such as Boux Avenue.
The group name is a useful way to distinguish Paphitis from other Dragons whose reputations centre on telecommunications, fitness, greeting cards or digital media. He appeared on the programme from the first series and became known for focusing closely on sales, margins and retail execution.
The question refers to the group founded by Paphitis, not simply to one of the individual retail companies he owned or developed. That distinction explains why the group’s founder is the appropriate answer.
