How the 2019 Inc. 5000 Companies Were Selected
Companies on the 2019 Inc. 5000 are ranked according to percentage revenue growth from 2015 to 2018. To qualify, companies must have been founded and generating revenue by March 31, 2015. They must be U.S.-based, privately held, for-profit, and independent--not subsidiaries or divisions of other companies--as of December 31, 2018. (Since then, some on the list may have gone public or been acquired.) The minimum revenue required for 2015 is $100,000; the minimum for 2018 is $2 million. As always, Inc. reserves the right to decline applicants for subjective reasons. Growth rates used to determine company rankings were calculated to three decimal places. There were 12 ties on this year's Inc. 5000.
