The people who invest in businesses on the British show Dragons' Den are called Dragons.
The title is the programme's British branding for the wealthy entrepreneurs and businesspeople who hear pitches. Contestants ask for a specified amount of money, usually in return for a percentage of their company, and the Dragons decide whether to make an offer.
The investors question founders about sales, profit, costs, valuation, competition and future plans. More than one Dragon may become interested, creating a negotiation between the entrepreneur and the panel. A pitch can also end without an offer if the investors do not consider the opportunity suitable.
The term is often confused with “sharks,” the name used by the separate American adaptation Shark Tank. “Business angels” is a general investment term, but it is not the official on-screen title used by the British programme. In Dragons' Den, the panel members are specifically called Dragons.
