Duncan Bannatyne founded the health-club company Bannatyne Group.
The Bannatyne Group operates health clubs and spas in the United Kingdom. The business became the central enterprise associated with Bannatyne, who developed a broad entrepreneurial career before becoming a Dragon's Den investor.
Bannatyne's route into business began with ventures including an ice-cream business, and he later expanded into care homes and health clubs. This varied background is why he was often presented as an experienced operator rather than solely as a financial backer.
He was part of the Dragon's Den panel for many years before leaving the programme. His departure is distinct from the later changes involving investors such as Kelly Hoppen and Touker Suleyman, who joined after Bannatyne's era on the show.
