The title of the American adaptation of the British programme Dragons' Den is Shark Tank.
Shark Tank is an American business reality television series in which entrepreneurs present companies or products to a panel of wealthy investors. The investors question the presenters and may offer money in exchange for an ownership stake or other negotiated terms.
The programme belongs to the international format family that also includes the British Dragons' Den. The central structure is recognisable across versions: a founder makes a pitch, investors examine the business and negotiations may follow. The names of the panel and the terminology vary by country.
A frequent misunderstanding is that Shark Tank was the original series. The British programme itself was adapted from the Japanese format Money Tigers, while Shark Tank is the American version. “Sharks” and “Dragons” are therefore market-specific labels for investors playing broadly comparable roles.
