About the List

Companies on the 2018 Inc. 500 are ranked according to percentage revenue growth from 2014 to 2017. To qualify, companies must have been founded and generating revenue by March 31, 2014. They must be U.S.-based, privately held, for-profit, and independent–not subsidiaries or divisions of other companies–as of December 31, 2017. (Since then, some 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. Note: Growth rates used to determine company rankings were calculated to two decimal places. There were two ties on this year’s Inc. 500; the com­panies with more revenue were placed higher.
