Michelle Mone joined Dragons' Den after founding the lingerie retailer Ultimo.
Mone founded Ultimo, a lingerie brand established in 1996. She became known for developing products intended to combine supportive construction with a fashionable appearance, and the brand gained visibility through celebrity and retail marketing.
She joined the Dragons' Den panel as a guest investor in 2011. Her business background gave her particular experience in product development, branding, retail and consumer marketing.
Mone is sometimes confused with Kelly Hoppen because both appeared as high-profile women in the broader Dragons' Den investor world. Hoppen was a designer and later a Dragon, while Mone's connection in this question is her founding of Ultimo and her guest-investor appearance.
