Hilary Devey joined the British Dragon's Den panel in 2011 after James Caan's departure.
Devey became an investor in the programme's eighth series. She was a businesswoman best known for founding Pall-Ex, a palletised freight distribution network. Her logistics background gave her a different commercial perspective from Dragons whose careers were mainly in retail, recruitment or technology.
Her arrival followed several panel changes during the show's early years. She appeared alongside established investors including Peter Jones and Deborah Meaden, and her direct style quickly became part of the programme's identity. She later left Dragon's Den after one series to present other television projects.
The question concerns the British programme's regular panel, not a guest appearance or a Dragon from an international adaptation. Hilary Devey is also sometimes confused with Kelly Hoppen, who joined the panel two years later.
