Touker Suleyman first joined the Dragons' panel on the British TV series Dragon's Den in 2015.
Suleyman is a British-Turkish entrepreneur and investor whose business interests include fashion and retail. He became a Dragon during the programme’s thirteenth series, adding experience in manufacturing, clothing and consumer brands to the investment panel.
His arrival followed the departures and changes that regularly reshape the Dragons' line-up. Because the programme has introduced investors across many series, joining years are often confused with the dates of later Dragons’ appointments.
The relevant fact is Suleyman’s first appearance as a Dragon, which was in 2015. It is distinct from the year he built or acquired any particular company.
