In the British television show Dragon's Den, the resident business investors are called Dragons.
The title uses the image of a den guarded by powerful figures who control access to investment. Entrepreneurs enter the studio, make a pitch, and negotiate with the Dragons over money, valuation, and ownership. The term is part of the programme's branding rather than a formal legal description of every investor's role.
A Dragon may offer all or part of the requested funding, propose different terms, join another Dragon in a shared deal, or decline to invest. The Dragons are selected for business experience and public recognition, but their investment decisions are personal to each pitch.
The title is sometimes confused with Shark Tank, the American version of the international format, where the investors are called Sharks. In Britain, the established term is Dragons, matching the programme's name and visual identity.
