Hello Ryan Cho,
Dragon's Den runs in the UK as well so you can check out the UK version too. You might also be interested in The Apprentice. UK version this season is pretty good (interesting, frustrating and funny at times). The Apprentice is not quite like Dragon's Den but the contestants are thrown into the deep end by having to create new products a lot of the time, so it still is interesting from a start-up point of view.
