The room where entrepreneurs present their business pitches in the British TV series Dragons' Den is called the den.
The title supplies the programme's central metaphor: the investors are dragons, and the entrepreneurs must enter their den to seek money and business support. A pitch normally includes a requested investment, an offered share of the company and answers to detailed questions from the panel.
The den is more than a decorative name. It signals the competitive atmosphere of the format, where investors can challenge a founder's valuation, sales figures, margins and plans for expansion. The entrepreneur must remain prepared while several dragons react differently to the same proposal.
It is sometimes called a boardroom because business negotiations occur there, but that is not the show's canonical term. The programme consistently identifies the pitch setting as the den.
