A trailblazer is a special breed in business. Fortune set out to identify entrepreneurs whose very young companies -- they had to have been officially launched in the past five years -- are already disrupting industries or changing the way businesses or consumers behave. But this isn't just a group of innovators. They're business leaders: Each of these founders is also the CEO (or equivalent) of his or her company. At a startup, that often means setting a vision and a strategy while managing the business, winning customers, motivating employees, and crucially, figuring out ways to remove the challenges that stand in the way of the company's success. And isn't knocking down barriers the very definition of trailblazing?
