Which Dragons' Den investor founded the British business Red Letter Days?

Rachel Elnaugh founded the British business Red Letter Days.

Red Letter Days became known for selling experience-based gifts, such as activities and special outings. The concept offered an alternative to ordinary products by giving recipients a memorable event or experience.

Elnaugh's success with the company led to her selection as one of the original investors on the British version of Dragons' Den. She appeared in the first series when the programme debuted on BBC Two in 2005.

A common mix-up is to associate the company with Deborah Meaden, who joined the panel after Elnaugh's departure. Meaden became a prominent long-term dragon, but Red Letter Days was founded by Elnaugh, not by one of the later female investors.
