The room where entrepreneurs pitch to investors on the British television show Dragons' Den is called the Den.
The title describes both the physical setting and the programme's dramatic concept. Entrepreneurs enter the Den, introduce their businesses and ask the dragons for investment. The name suggests a challenging environment in which founders must defend their figures and decisions under intense questioning.
The Den is not the same as the boardroom used in The Apprentice, another British business-themed television programme. In Dragons' Den, the entrepreneurs are normally established founders or business owners seeking capital, while the dragons act as potential private investors.
The phrase has also become part of everyday discussion about the show. Viewers may say that a product “went into the Den” or that a founder “won over the dragons,” but the formal name of the pitch room remains simply The Den.
