Which former Dragons' Den investor founded the retail company Theo Paphitis Group?

Theo Paphitis founded the retail company Theo Paphitis Group.

The Theo Paphitis Group is the umbrella business associated with Paphitis's retail interests and investments. Paphitis built his reputation through consumer and retail businesses, including the lingerie retailer La Senza, before becoming familiar to television audiences as an investor on Dragons' Den.

His business career is often reduced to his television appearances, but his principal commercial identity is as a retailer and entrepreneur. The group reflects his practice of owning, operating and investing in consumer-facing brands rather than being a single product company with one narrowly defined market.

This question is not asking which company Paphitis founded before the group or which brand he acquired. That distinction matters because La Senza and other retail names are separately associated with his career. The canonical answer to the group-name question is Theo Paphitis himself.
