Only about a third of all new companies last a decade, according to this infographic generated Intuit, a tax preparation software company. About 6 in 10 startups last the first three years.

Despite a steep failure curve, entrepreneurship is a job-creation goliath in the U.S. economy. That's because lots of people -- almost half a million each month in 2013 -- launched their own business. And of all new jobs generated in the U.S., 70 percent come from those upstart businesses.

Another 50,000 got financial help from an angel investors.
