Theo Paphitis became a Dragon on the BBC series Dragon's Den after joining the panel in its second series.
Paphitis is a British retail entrepreneur who became known to television audiences through his role as an investor on the programme. His business background included major retail interests, giving him a perspective centred on brands, shops, customers and commercial scale.
His arrival was part of the early expansion of the panel after the first series. The investor group was not fixed permanently: Dragons joined, departed and returned across the programme's long run, creating several distinct eras in its cast history.
Theo Paphitis is sometimes confused with the original investors because he became strongly associated with the classic line-up. The key distinction is that he joined in series two rather than being present from the British programme's launch.
