Which former Dragon's Den investor was the founder of the lingerie retailer Ultimo?

Michelle Mone was the founder of the lingerie retailer Ultimo and later became a Dragon's Den investor.

Mone established Ultimo in 1996 after identifying an opportunity for attractive, supportive lingerie with a distinctive design. The brand became especially associated with its cleavage-enhancing bra and grew into an international lingerie business. Mone's success at Ultimo led to her public recognition as a Scottish entrepreneur.

She joined Dragon's Den for its fifteenth series in 2015, appearing as a guest Dragon rather than becoming a permanent replacement for the core panel. Her role is therefore often described as that of a former Dragon or guest investor.

Ultimo is sometimes confused with Boux Avenue, another lingerie brand linked to a Dragon. Boux Avenue was founded by Theo Paphitis, whereas Ultimo was founded by Mone. The two businesses have separate founders and brand histories.
