Which Dragons' Den investor created the lingerie brand Ultimo?

Michelle Mone created the lingerie brand Ultimo.

Michelle Mone is a Scottish entrepreneur who founded Ultimo, a lingerie company launched in 1996. The brand became known for fashion-led lingerie and helped establish Mone as a prominent business figure before she joined the British Dragons' Den panel.

Mone appeared as a dragon in the programme for a limited period, bringing experience from product design, branding, manufacturing, and retail. Her story is often cited as an example of a founder building a consumer brand from a product idea rather than inheriting an established company.

Ultimo is sometimes confused with businesses associated with other women connected to the programme. Sara Davies is known for Crafter's Companion, while Deborah Meaden has a diverse investment portfolio. Those are separate entrepreneurial histories. The lingerie company in this question is Ultimo, and its founder is Michelle Mone.
