Which business did Dragons' Den investor Rachel Elnaugh co-found?

Dragons' Den investor Rachel Elnaugh co-founded the experience-gift company Red Letter Days.

Red Letter Days sold gift vouchers for experiences such as driving events, flying lessons and leisure activities. Elnaugh established the company with her husband, Saatchi, in 1989, helping develop the experience-gifting market in Britain before it became a familiar retail category.

The business expanded rapidly, but it later experienced financial difficulties and went into administration in 2005. Entrepreneur Peter Jones subsequently acquired the Red Letter Days brand and assets. This history is why Elnaugh and Jones are both associated with the company, although Elnaugh was its original founder.

Elnaugh appeared as a Dragon in the early BBC series. Red Letter Days is not the same business as Moonpig, which is an online greeting-card company founded by fellow Dragon Nick Jenkins.
