Deborah Meaden joined the British show Dragon’s Den in 2006.
Meaden is an English entrepreneur and investor whose business experience includes family entertainment, leisure and property. She joined the programme during its third series and became one of its most recognisable long-serving investors. Her style is often associated with concise questioning and close attention to financial fundamentals.
She joined after the programme had already established its original panel and after Theo Paphitis had become a Dragon. This makes 2006 different from the show’s launch year, 2005. Meaden also continued to appear in later series, making her tenure longer than that of many panel members.
The answer is Deborah Meaden, not Sara Davies or Kelly Hoppen, both of whom joined the panel much later.
