Theo Paphitis first appeared as an investor in series 2 of the British show Dragons' Den.
Paphitis is a Cyprus-born British retail entrepreneur who became known for businesses including Ryman, the stationery retailer, and other consumer brands. His appearance on Dragons' Den added a dragon with a strong retail and branding background to the early investor lineup.
He joined after the programme’s initial series, making him part of the first major expansion of the British panel. His expertise was especially relevant to contestants selling products through shops, chains or direct consumer channels, where distribution, margins and repeat sales were central issues.
The series number is important because Paphitis was not an original series-one investor. He also should not be confused with later dragons who had similarly prominent retail backgrounds. The answer refers to his first British series appearance, not the year of one of his businesses or a particular investment made on the show.
