Dozens of Houston-area businesses appear in this year’s Inc. 5000 ranking of the 5,000 fastest-growing private companies in the U.S., with a security software provider capturing the region’s No. 1 spot on the list.

Landing at No. 29 nationally and No. 1 in the software category, the top-ranked Houston-area private company is Houston-based Action1. The company recorded median revenue growth of 7,188 percent from 2021 to 2024, according to the Inc. 5000.

It’s the first appearance on the Inc. 5000 list for Action1, founded in 2018.

Action1 produces patch management software. A patch, or fix, quickly repairs software to resolve functionality problems, improve security or add features, according to TechTarget.

“Modern organizations understand that proactive patch management is essential to staying ahead of today’s rapidly evolving threat landscape,” Mike Walters, co-founder and president of Action1, said in a news release. “Our continued hypergrowth reflects the increased demand for enterprise cybersecurity innovation. You can’t be just powerful and secure — you must also be simple to deploy and scale and cost-effective.”
