The investor area where the Dragons sit during pitches on the British show Dragon's Den is called the Den.
The title gives the programme its central visual metaphor: entrepreneurs enter a room occupied by investors who scrutinise their proposals. The word “den” also distinguishes the British programme’s branding from the “tank” used by the American adaptation, Shark Tank.
A pitch usually begins with the entrepreneur standing before the panel and explaining the product, business, requested investment and offered equity. The Dragons then ask questions, and the entrepreneur may negotiate with one or more investors before leaving the room.
The Den is not simply a boardroom in the programme’s terminology. Although the setting resembles a business meeting, the show consistently uses its own dragon-themed language for the investors and their pitch space.
