Kickstarter a boon to entrepreneurs

Many entrepreneurs take a big risk when they start a business.

There are usually significant fixed costs. A retail store, for example, has to lease its space, buy a sign, cash registers, advertising, etc. — before they sell their first product. It's intimidating. There's the potential for major rejection — customers might not like what you're selling, and the business goes bankrupt.

What if you could remove that potential for rejection? What if you knew with certainty that the moment you opened your doors, your business would have enough customers?
