Which Dragons' Den investor founded the British health-club chain Bannatyne?

Duncan Bannatyne founded the British health-club chain Bannatyne.

Duncan Bannatyne is a Scottish entrepreneur, author, and television personality who became one of the best-known investors on Dragons' Den. His business group developed health clubs, hotels, and spas operating under the Bannatyne name.

Before becoming associated with fitness, Bannatyne built businesses in areas including care homes and vehicle sales. His Dragons' Den appearances made him familiar to a broad audience and established him as one of the programme's most recognisable early investors.

The company name is sometimes confused with a personal nickname or with a single gym location. Bannatyne is the entrepreneur's surname and the name used by the wider health-and-leisure chain. The brand's facilities are generally described as health clubs, with services that can include gyms, swimming pools, spas, and fitness classes.
