In the British TV show Dragon's Den, which investor was the founder of Red Letter Days?

Rachel Elnaugh was the founder of Red Letter Days, an experience-gift company.

Red Letter Days sold vouchers for activities and experiences rather than conventional physical presents. Elnaugh built the business before joining the original Dragon's Den panel, making her one of the show's earliest entrepreneur-investors.

The company later experienced financial difficulties and entered administration in 2005. It was subsequently acquired by rival experience-gift businesses, including Buyagift, which is why accounts of the brand can involve more than one company owner.

This history is distinct from Sara Davies's Crafter's Companion and Peter Jones's Phones International Group. Those businesses are also associated with Dragons, but they belong to different founders and industries.
