Which entrepreneur joined Dragon's Den as a regular investor in series 13 in 2015?

Touker Suleyman joined Dragon's Den as a regular investor in series 13 in 2015.

Suleyman is a British-Cypriot entrepreneur and investor associated especially with fashion, retail and manufacturing. His business background brought a strong focus on products, supply chains, margins and routes to market—issues that frequently determine whether a consumer brand can scale.

He joined after several earlier dragons had already established the show's investor culture. The distinction between series 13 and the year 2015 is useful because the programme's numbering and broadcast dates are often remembered separately. In this case, the thirteenth series corresponds to his arrival on the regular panel.

As with other dragons, Suleyman did not simply assess whether an idea was attractive. He also examined the founder's valuation, sales evidence, manufacturing economics and the percentage of equity offered for investment.
