In the UK television show Dragon's Den, which dragon founded Red Letter Days?

Rachel Elnaugh founded Red Letter Days before appearing as a dragon on the UK television show Dragon's Den.

Red Letter Days built its business around experience gifts, offering customers activities and memorable events rather than conventional physical presents. The company made Elnaugh a prominent entrepreneur and helped explain why she was selected for the programme's original investor panel.

Elnaugh's role on Dragon's Den belongs to the first series, while the business story also includes later financial difficulties. Those events are often compressed into a simple success-or-failure narrative, but the company’s rise and subsequent problems are separate parts of its history.

The answer is not Peter Jones, despite his long association with the programme, nor Deborah Meaden, whose investment portfolio includes many consumer-facing businesses. Red Letter Days is specifically linked to Elnaugh.
