Fourteen years ago this week, Hurricane Katrina ravaged New Orleans, leaving more than 11,000 residents homeless and hundreds of businesses shuttered. Rebuilding has been a major focus since then: According to the Bureau of Labor Statistics, there were 32,100 construction jobs in the city in July, an increase of about 2,200 from the month before the storm.

Construction is far from the only industry now growing in the Big Easy, though. For example, the hospitality and entertainment sectors have gotten a boost, thanks to the city's low cost of living and high rate of entrepreneurship. Further, investor groups like the NO/LA Angel Network are providing funding and mentorship to companies in biotech, food, education, and many others.

This year's Inc. 5000, an annual ranking of the fastest-growing private companies in the U.S., shows that growing variety. Here are the top six New Orleans businesses on the list, ranked by their three-year revenue growth rate.
