Which company founded by Rachel Elnaugh was discussed in the British show Dragon's Den?

Red Letter Days was the company founded by Rachel Elnaugh and discussed in connection with the British show Dragon's Den.

Elnaugh established Red Letter Days as an experience-gift business. Instead of selling only physical objects, the company offered customers activities and memorable events, an approach that helped popularise experience vouchers in the UK. She later appeared as one of Dragon's Den's original investors.

The company became commercially prominent but encountered serious financial problems and entered administration in 2005. It was subsequently acquired by other business interests, including Dragons' Den investor Peter Jones, who helped preserve and develop the brand.

Red Letter Days is often mixed up with later online gift-voucher businesses because many companies now sell experience packages. The key identification is its connection with Rachel Elnaugh and its early role in making experience gifts a recognisable retail category in Britain.
