The 2010 Inc. 5000: Top 10 States
Texas, 404 companies
Texas hosts the No. 1 company on this year's Inc. 500 list. Ambit Energy is a Dallas-based energy company that was one of many to take advantage of the state's deregulation of the energy markets in 2002, growing an astonishing 20,300 percent over the past few years. Of course, it helps that Texans consume the most energy in the nation, both per capita and as a whole.
