Which British Dragon's Den investor founded the fashion retailer Boux Avenue?

Theo Paphitis founded the fashion retailer Boux Avenue.

Boux Avenue is a British lingerie and nightwear retailer established by Theo Paphitis in 2011. The brand was designed as a high-street and online business combining lingerie, sleepwear and related fashion products.

Paphitis brought extensive retail experience to Dragon's Den. Before launching Boux Avenue, he had built a portfolio associated with Ryman and Robert Dyas. His television reputation was therefore closely connected with practical questions about stores, merchandising and routes to market.

Boux Avenue is not one of the businesses pitched by Paphitis as a contestant. He was an investor and panel member on the show, while Boux Avenue was his own later retail venture. That distinction separates the answer from products financed during televised negotiations.
