Money Tigers provided the original Japanese format for the British TV show Dragons' Den.
The British series adapted the Japanese programme Money Tigers, in which entrepreneurs presented business propositions to wealthy potential investors. The core idea travelled internationally: a founder asks for funding, investors assess the opportunity and negotiations can lead to an equity deal.
The name Dragons' Den reflects the British version's terminology for its investors. Other countries adapted the same underlying format with different titles, including Shark Tank in the United States. These programmes share the pitch-and-investment structure but have separate panels, broadcasters and local production histories.
A frequent mix-up is to identify Shark Tank as the source of the British series. Shark Tank is a later international adaptation in the same format family, not the Japanese programme that originated the concept used by Dragons' Den. Money Tigers is therefore the specific source title required here.
