Peter Jones has been a regular investor on the British show Dragons' Den since its first series.
Jones is a British entrepreneur and businessman who joined the original Dragons' Den panel when the programme launched in 2005. He is the only investor to have appeared as a Dragon in every series of the British programme, making his tenure central to the show's history.
His business interests have included technology, telecommunications, media and property. On the programme, he is known for scrutinising sales, margins, intellectual property and the valuation attached to an entrepreneur's company.
The other original Dragons did not remain continuously on the panel. Several left after particular series, while later investors joined the programme. That is why questions about the 'original Dragons' and the 'longest-serving Dragon' can produce different answers: Peter Jones is the continuing investor, not the only person who appeared in series one.
