For British viewers, this show is basically Dragon's Den. Identical concept, almost identical execution.
The things that are different are all improvements; the title is better - makes more sense to westerners. There is no annoying presenter doing pieces to camera. The dragons... sorry, sharks are billionaires, and every investment that they make results in multi-million dollar revenue for the entrepreneurs, and the amounts that they invest are often way bigger too, making the whole thing a higher stakes proposition than the humbler British version, and thus more entertaining.
Also, the sharks switch around, so it's not always the same five, but over the course of a season you get to know them all, so it's still comfortably familiar. And they're mostly likeable (like the British ones) but way ruder and a bit funnier.
Overall, it's Dragon's Den, but better.
