3 Houston companies land on Deloitte’s Technology Fast 500 list

trending up

Three Houston companies have made this year’s Deloitte North America Technology Fast 500 list.

The report ranks the fastest-growing technology, media, telecommunications, life sciences, fintech, and energy tech companies in North America. The Houston companies to make the list, along with their revenue growth rates from 2021-2024, include:

  • No. 16 Action1 Corp., a provider of cybersecurity software. Growth rate: 7,265 percent
  • No. 92 Cart.com, a commerce and logistics platform. Growth rate: 1,053 percent
  • No. 312 Tellihealth, a remote health care platform. Growth rate: 244 percent

“Houston’s unique blend of entrepreneurial energy and innovation continues to strengthen the local business community, and I’m thrilled to see Houston companies honored on the 2025 Deloitte Technology Fast 500 list. Congratulations to all the winners,” said Melinda Yee, managing partner in Deloitte’s Houston office.

Action1 is no stranger to lists like the Deloitte Technology Fast 500. For instance, the company ranked first among software companies and 29th overall on this year’s Inc. 5000, a list of the country’s fastest-growing private companies. Its growth rate from 2021 to 2024 reached 7,188 percent.

Mike Walters, president and co-founder of Action1, said in August that the Inc. 5000 achievement “reflects the dedication of Action1’s global team, who continue to execute against an ambitious vision: a world where cyberattacks exploiting vulnerabilities are entirely prevented across all types of devices, operating systems, and applications.”

Atlanta-based Impericus, operator of an AI-powered platform that connects health care providers with pharmaceutical and life sciences companies, topped the Deloitte list with a 2021-24 growth rate of 29,738 percent.

“Our mission is to set the standard for ethical AI-powered physician connections to pharma resources, accelerating and expanding patient access to needed treatments,” said Dr. Osama Hashmi, a dermatologist who’s co-founder and CEO of Impiricus. “As we continue to innovate quickly, we remain committed to building ethical bridges across this vital ecosystem.”

3+ Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from hardtech to digital solutions — recently making headlines in Houston innovation.

Wogbe Ofori, founder and chief strategist of WRX Companies

To Wogbe Ofori, the definition of entrepreneurship is simple: "To be more opportunity centric than risk averse." And Houston, as he says, has be entrepreneurial for a very long time — despite it being considered the specialty of a certain coastal region.

"Silicon Valley has hijacked the concept of innovation and entrepreneurship, and this city has been filled with entrepreneurs long before the concept of 'tech entrepreneurs,'" Ofori says on this week's episode of the Houston Innovators Podcast.

Ofori, the founder and chief strategist of WRX Companies, has developed a keen eye for entrepreneurship and innovation activity in Houston and shares his observations on the show. An adviser to Nauticus Robotics and strategist to Intuitive Machines and Jacobs, he's also served as a mentor across the local innovation community. Read more or listen below.

Deloitte just unveiled the fastest-growing technology companies in North America — and four businesses from Houston made the cut.

For the 29th year, 2023 Technology Fast 500 ranked top tech, media, telecommunications, life sciences, and energy technology companies based on fiscal year revenue growth from 2019 to 2022. While no Houston business was able to break into the top 100, four did make the cut for this year's list.

“It is great to see Houston represented alongside established technology hubs on this year’s Fast 500 list,” Amy Chronis, vice chair, US Energy and Chemicals Leader and Houston managing partner at Deloitte, says in a statement. “Houston is planting seeds for future innovation, and the companies named to this year’s list confirm our city’s value proposition as an innovative community. We look forward to this growth continuing in the future and extend our congratulations to this year’s Houston winners.” Read more.

Intuitive Machines has landed a nearly $9.5 million Air Force contract to develop technology for NASA’s Gateway project, the first space station that will orbit the moon. Specifically, the technology will support a high-powered nuclear fission system that will supply electricity for satellites, bypassing the need for power from solar, battery, or fuel-cell sources.

“As space exploration ventures become more ambitious and diverse, the need for efficient and reliable power sources in space is paramount,” Pete McGrath, vice president of business development at Intuitive Machines, says in a news release. “Developing the ability to expand power sources beyond solar, which requires heavy battery storage, could remove the burden of constantly worrying about a spacecraft’s arrays relative to the sun, and potentially deliver long-term stability for satellites that would otherwise lose power over time.”

Second, Intuitive Machines has set January window for the launch of its IM-1 lunar mission in conjunction with private aerospace company SpaceX. The liftoff is targeted for a multiday window that opens January 12, 2024. Read more.

Attendees can expect to hear from leaders of global institutions, including the World Economic Forum, U.S. Chamber of Commerce, McKinsey Health Institute, Global Brain Economy Initiative, Davos Alzheimer’s Collaborative, Business Collaborative for Brain Health (UsAgainstAlzheimer’s), Rice University, Memorial Hermann, MD Anderson and many others.

Day 1 of the conference will focus on "Enabling Human Flourishing & Economic Growth." Day 2 will focus on "Scaling Innovation & AI Solutions in the Brain Economy."

Keynotes will be delivered by:

  • Lexi Branson, vice president of health policy at the U.S. Chamber of Commerce
  • Kana Enomoto, director of the McKinsey Health Institute
  • Megan Henshall, founder of Google Experience Institute (Xi)
  • Ryan Howard, co-lead of Google Experience Institute (Xi)

Texas solar power poised to surpass coal for the first time in 2026

Powering Texas

Solar power promises to shine even brighter in Texas this year.

A new forecast from the U.S. Energy Information Administration (EIA) indicates that for the first time, annual power generation from utility-scale solar will surpass annual power generation from coal across the territory covered by the Electric Reliability Council of Texas (ERCOT).

Solar generation is expected to reach 78 billion kilowatt-hours in 2026 in the ERCOT grid, compared with 60 billion kilowatt-hours for coal, the EIA forecast says. The ERCOT grid supplies power to about 90 percent of Texas, including the Houston area.

“Utility-scale solar generation has been increasing steadily in ERCOT as solar capacity additions help meet rapid electricity demand growth,” the forecast says.

Although natural gas remains the dominant source of electricity generation in ERCOT, accounting for an average 44 percent of electricity generation from 2021 to 2025, solar’s share of the generation mix rose from four percent to 12 percent. During the same period, coal’s share dropped from 19 percent to 13 percent.

EIA predicts about 40 percent of U.S. solar capacity, or 14 billion kilowatt-hours, added in 2026 will come from Texas.

Although EIA expects annual solar generation to exceed annual coal generation in 2026, solar surpassed coal in ERCOT on a monthly basis for the first time in March 2025, when solar generation totaled 4.33 billion kilowatt-hours and coal’s totaled 4.16 billion kilowatt-hours. Solar generation continued to exceed that of coal until August of that year.

“In 2026, we estimate that solar exceeded coal for the first time in March, and we forecast generation from solar installations in ERCOT will continue to exceed that from coal until December, when coal generation exceeds solar,” says EIA. “We expect solar generation to exceed that of coal for every month in 2027 except January and December.”

For 2027, EIA forecasts annual solar generation of 99 billion kilowatt-hours in the ERCOT grid, compared with 66 billion kilowatt-hours of annual coal generation.

In April, ERCOT projected almost 368 billion kilowatt-hours of demand in ERCOT’s territory by 2032. ERCOT’s all-time peak demand hit 85.5 billion kilowatt-hours in August 2023.

“Texas is experiencing exceptional growth and development, which is reshaping how large load demand is identified, verified, and incorporated into long-term planning,” ERCOT President and CEO Pablo Vegas said. “As a result of a changing landscape, we believe this forecast to be higher than expected … load growth.”

Intuitive Machines strikes $49.3M deal to expand lunar communications network

space deal

Houston-based Intuitive Machines is bulking up its space-to-ground data network with the acquisition of United Kingdom-based Goonhilly Earth Station and its U.S. arm, COMSAT.

The $49.3 million cash-and-stock deal would add 44 antennas to Intuitive Machines’ network. The acquisition is expected to close in the third quarter.

Intuitive Machines, a space infrastructure and services company, designs, builds, and operates spacecraft and data networks for lunar and deep-space missions. Goonhilly operates a satellite Earth station in Cornwall, England.

Intuitive Machines says Goonhilly’s and COMSAT’s civil, commercial, and government customers will complement its current customer base and broaden its reach into related sectors.

“Customers have been clear that they want a single, integrated, and resilient solution for their communications and [position, navigation, and timing] needs as they accelerate missions at an unprecedented pace,” Steve Altemus, co‑founder and CEO of Intuitive Machines, said in a news release.

Kenn Herskind, executive chairman of Goonhilly, says the acquisition “will allow us to scale that capability globally and directly support the next era of lunar exploration. Together, we will be creating a commercial lunar communications network that is interoperable, resilient, and ready to support Artemis and international missions.”
