Atlanta can go ahead and claim its place as a bona fide startup hotbed. This year's Inc. 5000 list of fastest-growing companies in America is proof: The Georgia capital's 101 businesses on the list, the fourth-most of any U.S. city, boast an average revenue growth rate of 86 percent. The only city above Atlanta in both metrics is New York City.

From bridge building to custom lunch catering, here are the top 10 Atlanta-based companies from the 2019 Inc. 5000:
