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.”

Abbott highlights Texas AI boom, with Houston projects on the horizon

AI investments are booming in Texas, Gov. Greg Abbott says. And Houston is poised to benefit from this surge.

At a recent Texas Economic Development Corp. gathering in the Dallas-Fort Worth area, Abbott said AI projects on the horizon in the Lone Star State would be bigger than the $500 billion multistate Project Stargate, according to the Dallas Business Journal. So far, Stargate includes three AI data centers in Texas.

Stargate, a new partnership among OpenAI, Oracle, Softbank, and the federal government, is building AI infrastructure around the country. The project’s first data center is in Abilene, and the center’s second phase is underway. Once the second phase is finished, the 875-acre site will host eight buildings totaling about 4 million square feet with a power capacity of 1.2 gigawatts. An additional 600 megawatts of capacity might be added later.

On Sept. 23, Stargate announced the development of another five AI data centers in the U.S., including a new facility in Shackelford County, Texas, near Abilene. That facility is likely a roughly $25 billion, 1.4-gigawatt AI data center that Vantage Data Centers is building on a 1,200-acre site in Shackelford County.

Another will be in Milam County, between Waco and Austin. In conjunction with Stargate, OpenAI plans to occupy the more than $3 billion center, which will be situated on a nearly 600-acre site, the Austin Business Journal reported. OpenAI has teamed up with Softbank-backed SB Energy Global to build the facility.

Abbott said several unannounced AI projects in Texas — namely, data centers — will be larger than Stargate.

“Bottom line is ... when you look at diversification, the hottest thing going on right now is artificial intelligence,” Abbott said.

The Houston area almost certainly stands to attract some of the projects teased by the governor.

In Houston, Taiwanese tech manufacturer Foxconn already is investing $450 million to make AI servers at the 100-acre Fairbanks Logistics Park, which Foxconn recently purchased for a reported $142 million. The park features four industrial buildings totaling one million square feet. It appears Foxconn will manufacture the servers for Apple and Nvidia, both of which have announced they’ll open server factories in Houston.

The Foxconn, Apple, and Nvidia initiatives are high-profile examples of Houston’s ascent in the AI economy. A report released in July by the Brookings Institution identified Houston as one of the country’s 28 “star” hubs for AI.

The Greater Houston Partnership says the Houston area is undergoing an "AI-driven data revolution."

“As Houston rapidly evolves into a hub for AI, cloud computing, and data infrastructure, the city is experiencing a surge in data center investments driven by its unique position at the intersection of energy, technology, and innovation,” the partnership says.

A team of engineers and pediatric surgeons led by Rice University’s Rice360 Institute for Global Health Technologies has developed a cost-effective treatment for infants born with gastroschisis, a congenital condition in which intestines and other organs are developed outside of the body.

The condition can be life-threatening in economically disadvantaged regions without access to equipment.

The Rice-developed device, known as SimpleSilo, is “simple, low-cost and locally manufacturable,” according to the university. It consists of a saline bag, oxygen tubing and a commercially available heat sealer, while mimicking the function of commercial silo bags, which are used in high-income countries to protect exposed organs and gently return them into the abdominal cavity gradually.

Houston native picked for 2025 class of NASA astronaut candidates

space crew

NASA has selected 10 new astronaut candidates, including one whose hometown is Houston, for its 2025 training class. The candidates will undergo nearly two years of training before they can assume flight assignments.

The 10 future astronauts were introduced during a recent ceremony at NASA’s Johnson Space Center, whose facilities include an astronaut training center. NASA received more than 8,000 applications for the 10 slots.

“Representing America’s best and brightest, this astronaut candidate class will usher in the Golden Age of innovation and exploration as we push toward the moon and Mars,” said Vanessa Wyche, director of NASA Johnson.

NASA’s 24th astronaut class reported for duty in mid-September at Johnson Space Center. Their training will prepare them for missions to the International Space Station and the moon, among other activities. Graduates will become members of NASA’s astronaut corps.

Among the recently selected candidates is Anna Menon, who was born in Houston and considers it her hometown. She’s married to NASA astronaut Dr. Anil Menon, a flight surgeon who completed his training in 2022.

Most recently, Anna Menon was a senior engineer at Elon Musk’s SpaceX, where she spent seven years managing crew operations for the Dragon and Starship spacecraft. Previously, Menon worked at NASA’s Mission Control Center in Houston, where she supported medical software and hardware aboard the International Space Station.

In 2024, Menon flew into space as a mission specialist and medical officer aboard SpaceX’s Polaris Dawn private spacecraft. A highlight of the low-orbit trip was the first commercial spacewalk.

Texas native Rebecca Lawler, a native of the Dallas-Fort Worth suburb of Little Elm, is one of Menon’s nine classmates.

Lawler, a former lieutenant commander in the Navy, was a Navy P-3 pilot and experimental test pilot who logged over 2,800 flight hours aboard more than 45 aircraft. At the time she was chosen to be an astronaut candidate, Lawler was a test pilot for United Airlines.

The eight other astronaut candidates in the 2025 class are:

  • Ben Bailey, who was born and raised in Charlottesville, Virginia
  • Lauren Edgar, whose hometown is Sammamish, Washington
  • Adam Fuhrmann, who’s from Leesburg, Virginia
  • Cameron Jones, a native of Savanna, Illinois
  • Yuri Kubo, a native of Columbus, Indiana
  • Imelda Muller, whose hometown is Copake Falls, New York
  • Erin Overcash, who’s from Goshen, Kentucky
  • Katherine Spies, a native of San Diego
