Launching a business is no small task. No matter how big an idea you think you have, it still takes a lot of work and a ton of cash. Enter the Dragon's Den, where aspiring entrepreneurs pitch their business concepts and products to a panel of business moguls who have the cash and the know-how to make it happen.

They've all been there themselves, so you better not walk into the Den unprepared. It takes more than passion to convince these boardroom giants that your idea is worth their attention.

The Dragons are ruthless and rightly so - it's their own personal money on the line.
