Which Dragon's Den investor is associated with the retail chain Robert Dyas?

Theo Paphitis is associated with the British retail chain Robert Dyas.

Robert Dyas is a British retailer selling household goods, hardware, DIY products and related items. Theo Paphitis acquired the company in 2004, adding it to a retail portfolio that also included his involvement with Ryman and other consumer businesses.

Paphitis later became widely recognised as an investor on Dragon's Den. His background in retail helps explain why he often evaluated pitches through the lens of distribution, margins, customer demand and store or online sales potential.

Robert Dyas is sometimes described as a business Paphitis founded, but the more precise fact is that he acquired it. That distinction matters because Ryman is the retail chain associated with his founding career, whereas Robert Dyas is the established retailer he bought and developed.
