How the 2013 Inc. 5000 Companies Were Selected
This year's list measures revenue growth from 2009 through 2012. To qualify, companies must have been founded and generating revenue by March 31, 2009.
Additionally, they had to be U.S.-based, privately held, for profit, and independent--not subsidiaries or divisions of other companies-as of December 31, 2012. (Since then, a number of companies on the list have gone public or been acquired.)
The minimum revenue required for 2009 is $100,000; the minimum for 2012 is $2 million. Revenue figures given in the company profiles are for calendar year 2012.
Employee counts are as of December 31, 2012. Full-time and part-time employees are included in the employee counts; independent contractors are not.
As always, Inc. reserves the right to reject applicants for subjective reasons.
