Nick Robertson appeared as a guest Dragon on Dragon's Den after founding the online fashion retailer ASOS.
Robertson co-founded ASOS in 2000 with Quentin Griffiths. The company began under the name As Seen On Screen, reflecting its early focus on clothing and products associated with celebrities and television. It later became a major online fashion retailer serving customers in numerous markets.
His appearance as a guest Dragon connected the programme's investment format with one of Britain's most prominent digital retail success stories. A guest Dragon is invited for a particular episode or series period and should not automatically be described as a permanent member of the regular panel.
Nick Jenkins is another entrepreneur named Nick who became a Dragon, but he founded Moonpig rather than ASOS. Julian Dunkerton is associated with Superdry, while Simon Fuller is a music and entertainment executive. Those distinctions identify Robertson as the correct answer.
