Which entrepreneur became the first female investor on the UK version of Dragons' Den?

Rachel Elnaugh became the first female investor on the UK version of Dragons' Den. She was part of the original investor lineup when the programme launched in 2005.

Elnaugh was known as a businesswoman and entrepreneur before joining the television series. Her company Red Letter Days sold experience gifts, making her a particularly recognisable figure in the early British business-investment landscape.

Deborah Meaden is often given as the answer because she became one of the show's best-known female dragons, but she joined the panel later. Elnaugh left the programme after its first series, while Meaden subsequently became a long-running investor.
