Nine Arizona companies, led by Freestar, make prestigious Inc. 500 list

Nine Arizona companies, all of them based in the Valley, made the cut for Inc. magazine’s list of the top 500 fastest-growing firms in the nation for 2020.

Topping the state list was last year’s national leader and Inc.’s 2019 cover story, Freestar LLC, a company that helps publishers boost revenue by optimizing their online advertising. This year, Freestar dropped to No. 36 overall on a still-staggering growth rate of 7,239%.
