Which Dragon's Den investor is also known for founding the health-club chain Bannatyne?

Duncan Bannatyne is the Dragon's Den investor known for founding the Bannatyne health-club chain.

Bannatyne built his business career across several sectors before developing a major leisure and health-club group. The Bannatyne Group became associated with gyms, spas and hotels, giving him direct experience in membership businesses, property, staffing and service operations.

That background shaped his role on Dragon's Den, where he evaluated entrepreneurs seeking investment and often challenged them on profitability, expansion and the realism of their financial forecasts. His presence on the programme also made his distinctive Scottish accent and direct questioning familiar to a broad television audience.

The Bannatyne name is not the name of a single fitness product. It refers to a wider group of health clubs and leisure businesses. Duncan Bannatyne is also known for philanthropy and public campaigning, but his Dragon's Den association rests especially on his entrepreneurial career and the health-club group bearing his name.
