Kelly Hoppen joined the British programme in 2013 after building the Kelly Hoppen Interiors brand.
Hoppen is a British interior designer whose work is associated with a minimalist style often described through neutral colours, clean lines, and a balance of textures. She established Kelly Hoppen Interiors and developed a wider design brand covering interiors, products, and related licensing.
She joined Dragons' Den for series 11, which aired in 2013. Her background gave the panel a Dragon whose main expertise was design and luxury interiors rather than finance, manufacturing, or technology alone.
Hoppen left the regular Dragons' Den panel after several series. She is also known for television appearances and design publications, but her name in this question refers specifically to the investor and interior-design entrepreneur, not to the similarly named British athlete Kelly Holmes.
