Deborah Meaden first appeared as a dragon in series 3 of the British TV series Dragons' Den.
Meaden is an English businesswoman and investor who became one of the programme's most recognisable panel members. Her background includes business leadership and investment, giving her the commercial experience needed to assess pitches, ownership percentages and growth plans.
Her arrival did not coincide with the programme's launch. The first two series established the British format with an earlier panel, and Meaden joined in the third series as the cast began to evolve.
Series numbers can be confused with broadcast years because a television series may be filmed in one period and transmitted in another. The answer refers to the numbered series in which Meaden debuted on the panel, rather than a calendar year or a later return to the programme.
