In the British TV series Dragon's Den, entrepreneurs make their pitches in the den.
The den is the programme's deliberately intimidating pitch environment. Contestants walk into the room, introduce their business, and state how much investment they want in exchange for a specified percentage of equity. The Dragons then question the founders about sales, costs, margins, intellectual property, competition, and valuation.
The title uses the word “den” as a metaphor for a challenging encounter with powerful investors. It is not simply a generic boardroom: the name connects the set, the programme title, and the idea that entrepreneurs must survive a demanding interrogation.
A common mix-up is to call the setting the “boardroom,” a term strongly associated with other business reality programmes. In Dragon's Den, “the den” is the established name used by the British series. The show’s most memorable moments often involve a pitch ending with a Dragon saying they are out.
