In the BBC television series Dragon's Den, entrepreneurs pitch their businesses in The Den.
The Den is the programme's central setting and gives the format its title. Entrepreneurs walk into the room, explain their business, and ask the Dragons for a specific amount of money in exchange for a percentage of their company. The investors then question the entrepreneur about sales, costs, valuation, intellectual property and plans for growth.
The room is deliberately designed to make the pitch feel formal and high-pressure. Its long layout places the entrepreneur at one end and the investors behind a desk at the other. This visual arrangement has become one of the show's most recognisable features.
The British programme is an adaptation of the Japanese format Money Tigers, which was later known internationally through versions such as Shark Tank. The Dragons are investors rather than judges: they may offer money, negotiate terms, or decline to invest. A televised agreement can also fail during later due diligence.
