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

Theo Paphitis founded the fashion brand Boux Avenue.

Boux Avenue is a British retailer specialising in lingerie, nightwear and related fashion products. Theo Paphitis launched the brand in 2011, adding a consumer-facing fashion business to his wider portfolio of retail interests.

The brand was developed with a focus on accessible lingerie and an in-store and online shopping experience aimed at a younger market. Its name is sometimes confused with the names of established lingerie chains, but Boux Avenue is a distinct brand created under Paphitis's retail group.

Paphitis's Dragon's Den appearances helped make him familiar to television audiences, but his business career was established through retail ownership and investment beyond the programme. His connection with Boux Avenue is therefore a company-founder fact, not a claim that the brand originated as a pitch on the show.
