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.”

Annual report ranks 4 Houston tech companies on list of fasting growing businesses

trending up

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.”

The four Houston companies that make the 2023 list are:

  • Direct Digital Holdings at No. 108 with 1,325 percent growth
  • Liongard at No. 208 with 680 percent growth
  • NatGasHub.com at No. 356 with 364 percent growth
  • P97 Networks at No. 506 with 225 percent growth

Thirty Texas companies made the list of the 541 ranked, making it the fourth most concentrated hub on the list behind the Bay Area, Tri-State Area, and New England. The companies on the list reported a revenue growth ranging from 201 percent to 222,189 percent over the three-year time frame from 2019 to 2022. The average growth rate was 1,934 percent and a median growth rate of 497 percent.

“Each year, we look forward to reviewing the progress and innovations of our Technology Fast 500 winners," Paul Silverglate, vice chair, Deloitte LLP and U.S. technology sector leader, says in the release. "This year is especially celebratory as we expand the number of winners to better represent just how many companies are developing new ideas to progress our society and the world, especially during a slow economy. While software and services and life sciences continue to dominate the top 10, we are encouraged to see other categories making their mark."

Software dominated the industry breakdown with 57 percent of the companies working in that field. However, the top company for 2023 was Vir Biotechnology Inc., a life science company that developed a COVID-19 treatment. Vir was also the top company in 2022.

Last year, only one Houston company made the list. At No. 372 Onit reported a revenue increase of 369 percent. The company also made the 2021 list, along with Graylog and Enercross.

A few Houston innovators have helped connect health care workers in Haiti to some PPE. Ana Rojas Bastidas, founder of Orolait, and Jacques and Smriti Agrawal Zaneveld of Lazarus 3D, teamed up to ship over 1,000 pieces of PPE to United States Foundation for the Children of Haiti which supported orphanages, schools, and a hospital called Hopital Espoir.

In the middle of April, Bastidas saw the organization's need for PPE and saw how Lazarus 3D was creating materials. The group in Haiti received the supplies by the beginning of June.

"I'm really proud of the collaboration between myself and the Lazarus 3D team," Bastidas says. "Smriti and Jacques are absolute gems and while our businesses are completely separate, we found a common problem we both had the resources to tackle."

Houston scores $120M in new cancer research and prevention grants

cancer funding

The Cancer Prevention and Research Institute of Texas has granted more than $120 million to Houston organizations and companies as part of 73 new awards issued statewide.

The funds are part of nearly $154 million approved by the CPRIT's governing board earlier this month, bringing the organization's total investment in cancer prevention and research to more than $4 billion since its inception.

“Today marks an important milestone for CPRIT and for every Texan affected by cancer,” CEO Kristen Doyle said in a news release. “Texas has invested $4 billion in the fight against one of the world’s greatest public health challenges. Over 16 years, that support has helped Texas lead the search for breakthrough treatments, develop new cancer-fighting drugs and devices, and—most importantly—save tens of thousands of lives through early cancer detection and prevention. Every Texan should know this effort matters, and we’re not finished yet. Together, we will conquer cancer.”

A portion of the funding will go toward recruiting leading cancer researchers to Houston. CPRIT granted $5 million to bring John Quackenbush to Baylor College of Medicine. Quackenbush comes from the Harvard T.H. Chan School of Public Health and is an expert in computational and systems biology. His research focuses on complex genomic data to understand cancer and develop targeted therapies.

The University of Texas M.D. Anderson Cancer Center also received $3 million to recruit Irfan Asangani, an associate professor at the University of Pennsylvania Perelman School of Medicine. His research focuses on how chromatin structure and epigenetic regulation drive the development and progression of cancer, especially prostate cancer.

Other funds will go towards research on a rare, aggressive kidney cancer that impacts children and young adults; screening programs for breast and cervical cancer; and diagnostic technology.

In total, cancer grants were given to:

  • The University of Texas M.D. Anderson Cancer Center: $29.02 million
  • Baylor College of Medicine: $15.04 million
  • The University of Texas Health Science Center at Houston: $9.37 million

U.S. News names 5 Houston suburbs as the best places to retire in 2026

Retirement Report

Houston-area suburbs should be on the lookout for an influx of retirees in 2026. A new study by U.S. News and World Report has declared The Woodlands and Spring as the fourth and fifth best cities to retire in America, with three other local cities making the top 25.

The annual report, called "250 Best Places to Retire in the U.S. in 2026" initially compared 850 U.S. cities, and narrowed the list down to a final 250 cities (up from 150 previously). Each locale was analyzed across six indexes: quality of life for individuals reaching retirement age, value (housing affordability and cost of living), health care quality, tax-friendliness for retirees, senior population and migration rates, and the strength of each city's job market.

Midland, Michigan was crowned the No. 1 best place to retire in 2026. The remaining cities that round out the top five are Weirton, West Virginia (No. 2) and Homosassa Springs, Florida (No. 3).

According to U.S. News, about 15 percent of The Woodlands' population is over the age of 65. The median household income in this suburb is $139,696, far above the national average median household income of $79,466.

Though The Woodlands has a higher cost of living than many other places in the country, the report maintains that the city "offers a higher value of living compared to similarly sized cities."

"If you want to buy a house in The Woodlands, the median home value is $474,279," the city's profile on U.S. News says. "And if you're a renter, you can expect the median rent here to be $1,449." For comparison, the report says the national average home value is $370,489.

Spring ranked as the fifth best place to retire in 2026, boasting a population of more than 68,000 residents, 11 percent of whom are seniors. This suburb is located less than 10 miles south of The Woodlands, while still being far enough away from Houston (about 25 miles) for seniors to escape big city life for the comfort of a smaller community.

"Retirees are prioritizing quality of life over affordability for the first time since the beginning of the COVID-19 pandemic," said U.S. News contributing editor Tim Smart in a press release.

The median home value in Spring is lower than the national average, at $251,247, making it one of the more affordable places to buy a home in the Houston area. Renters can expect to pay a median $1,326 in monthly rent, the report added.

Elsewhere in Houston, Pearland ranked as the 17th best place to retire for 2026, followed by Conroe (No. 20) and League City (No. 25).

Other Texas cities that ranked among the top 50 best places to retire nationwide include Victoria (No. 12), San Angelo (No. 28), and Flower Mound (No. 37).

The top 10 best U.S. cities to retire in 2026 are:

  • No. 1 – Midland, Michigan
  • No. 2 – Weirton, West Virginia
  • No. 3 – Homosassa Springs, Florida
  • No. 4 – The Woodlands, Texas
  • No. 5 – Spring, Texas
  • No. 6 – Rancho Rio, New Mexico
  • No. 7 – Spring Hill, Florida
  • No. 8 – Altoona, Pennsylvania
  • No. 9 – Palm Coast, Florida
  • No. 10 – Lynchburg, Virginia

Micro-nuclear reactor to launch at Texas A&M innovation campus in 2026

nuclear pilot

The Texas A&M University System and Last Energy plan to launch a micro-nuclear reactor pilot project next summer at the Texas A&M-RELLIS technology and innovation campus in Bryan.

Washington, D.C.-based Last Energy will build a 5-megawatt reactor that’s a scaled-down version of its 20-megawatt reactor. The micro-reactor initially will aim to demonstrate safety and stability, and test the ability to generate electricity for the grid.

The U.S. Department of Energy (DOE) fast-tracked the project under its New Reactor Pilot Program. The project will mark Last Energy’s first installation of a nuclear reactor in the U.S.

Private funds are paying for the project, which Robert Albritton, chairman of the Texas A&M system’s board of regents, said is “an example of what’s possible when we try to meet the needs of the state and tap into the latest technologies.”

Glenn Hegar, chancellor of the Texas A&M system, said the 5-megawatt reactor is the kind of project the system had in mind when it built the 2,400-acre Texas A&M-RELLIS campus.

The project is “bold, it’s forward-looking, and it brings together private innovation and public research to solve today’s energy challenges,” Hegar said.

As it gears up to build the reactor, Last Energy has secured a land lease at Texas A&M-RELLIS, obtained uranium fuel, and signed an agreement with DOE. Founder and CEO Bret Kugelmass said the project will usher in “the next atomic era.”

In February, John Sharp, chancellor of Texas A&M’s flagship campus, said the university had offered land at Texas A&M-RELLIS to four companies to build small modular nuclear reactors. Power generated by reactors at Texas A&M-RELLIS may someday be supplied to the Electric Reliability Council of Texas (ERCOT) grid.

Also in February, Last Energy announced plans to develop 30 micro-nuclear reactors at a 200-acre site about halfway between Lubbock and Fort Worth.
