American author Napoleon Hill said that, "Ideas are the beginning points of all fortunes."

In Cleveland, good ideas lead to an ever-growing array of new businesses filling needs across a wide spectrum. From mobile restaurants to got-to-have-it smartphone apps, small start-ups are the lifeblood of a progressive economy. But good ideas can grow, too, blossoming into major companies that employ hundreds.

So, what's your big idea?
