Which Dragon's Den investor is associated with the health-club company Bannatyne Group?

Duncan Bannatyne is the Dragon's Den investor associated with the Bannatyne Group health-club company.

Bannatyne built a business empire that included health clubs, spas, and hotels. The Bannatyne Group became one of the most recognisable health and fitness brands in the United Kingdom, with clubs offering gym facilities and related services. His entrepreneurial background shaped the practical, numbers-focused advice he often gave to pitchers.

Bannatyne joined the Dragon's Den panel in the programme's early years and became one of its best-known investors. His Scottish accent, direct style, and interest in scalable businesses helped make him a distinctive member of the original BBC-era line-up.

The company name can make the answer especially clear: Bannatyne Group uses the investor's surname. It should not be confused with Theo Paphitis's retail businesses, James Caan's recruitment background, or Touker Suleyman's fashion and retail interests. Bannatyne later left the regular panel, but his business remains closely associated with his public profile.
