Which Dragon's Den investor is the founder of the lingerie brand Ultimo?

Michelle Mone is the founder of the lingerie brand Ultimo.

Mone, a Scottish entrepreneur, launched Ultimo in 1996 after developing a gel-filled bra designed to improve the fit and appearance of low-cut clothing. The brand became associated with celebrity endorsements and high-profile fashion marketing, helping turn a specialist lingerie product into an internationally recognised business.

She appeared as a guest Dragon on the British programme rather than being part of the long-term regular panel. That distinction matters because Dragon's Den has featured guest investors alongside permanent or recurring Dragons across different series.

Mone is sometimes described only as a lingerie entrepreneur, but her career has also included other business and public roles. Ultimo itself is the key link between her and the programme: the brand made her a prominent business figure before her television appearances.
