The investor Peter who has appeared on the British programme Dragons' Den since its first series is Peter Jones.
Peter Jones is a British entrepreneur and investor, and he has been a central member of the Dragons' Den panel since the programme began in 2005. He is known for examining the commercial potential of products, the quality of the founders, and the financial terms offered in a pitch.
Jones has interests and experience across areas including technology, media, retail, and consumer businesses. On the programme, his decisions are based on the proposal presented in the studio, although the broadcast edit may not show every stage of the investment process.
The surname is sometimes confused with those of other long-serving investors. Theo Paphitis and Duncan Bannatyne were also prominent early dragons, but neither is Peter’s surname. The question identifies Peter specifically so that the answer is the surname Jones rather than the name of another panel member.
