How the 2018 Inc. 5000 Companies Were Selected
The 2018 Inc. 5000 is ranked according to percentage revenue growth when comparing 2014 and 2017. To qualify, companies must have been founded and generating revenue by March 31, 2014. They had to be U.S.-based, privately held, for profit, and independent—not subsidiaries or divisions of other companies—as of December 31, 2017. (Since then, a number of companies on the list have gone public or been acquired.) The minimum revenue required for 2014 is $100,000; the minimum for 2017 is $2 million. As always, Inc. reserves the right to decline applicants for subjective reasons.
