Duncan Bannatyne founded the health-club chain Bannatyne Fitness and later appeared as an investor on the British TV show Dragons' Den.
Bannatyne is a Scottish entrepreneur whose business career began in areas including ice cream and care homes before expanding into health clubs and hotels. His fitness company became one of the most visible parts of his business empire and bears his surname.
As a Dragon, he was associated with direct questioning and a willingness to examine whether entrepreneurs understood their numbers. His personal background made him especially recognizable to viewers, because his name was also attached to the business group he had built outside television.
The company is often called Bannatyne Health Club or Bannatyne Fitness in different contexts, but the entrepreneur's name is Duncan Bannatyne. This question concerns the founder, not the chain's current management or a specific club location. Bannatyne left the regular Dragons' Den panel after the early era of the series.
