Which Dragons' Den investor founded the mail-order gift company Red Letter Days?

Rachel Elnaugh founded the mail-order gift company Red Letter Days.

Elnaugh launched Red Letter Days in 1996. The company sold experience gifts, allowing customers to buy vouchers for activities and memorable occasions rather than only conventional physical presents. This helped popularise experience-based gifting in the British market.

She became one of the original investors on Dragons' Den when the BBC programme began in 2005. Her entrepreneurial profile was closely linked with branding, direct marketing and the growth of experience vouchers.

Red Letter Days later encountered financial difficulties and entered administration in 2005. The brand was subsequently acquired by Peter Jones, another Dragons' Den investor. This history is why references to the company can involve both Elnaugh as founder and Jones as a later owner.
