Money Tigers is the Japanese business-pitch format adapted into the British TV series Dragon's Den.
The Japanese programme, titled Money Tigers, supplied the basic format: entrepreneurs present proposals to a panel of potential investors and seek funding in return for equity. The format was later adapted in several countries, with the investor panel receiving different names.
In Britain, the investors became Dragons, reflecting the programme's title. In the United States, the related adaptation became Shark Tank, giving the international format a different animal metaphor while retaining the central pitch-and-negotiate structure.
Money Tigers is often confused with Dragon's Den itself because the two programmes share the same premise. The former is the Japanese source format; the latter is the British adaptation that began broadcasting in 2005.
