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.”

4 fast-growing Houston tech companies secure spots on Deloitte list

big wins

Deloitte’s annual North America Technology Fast 500 list includes four Houston companies this year — all boasting of significant growth.

For Houston, Direct Digital Holdings, Inc. took the highest-ranking spot at No. 101 (up from 108 previous year) with 1,184 percent growth. NatGas Hub LLC (No. 286, 407 percent growth), Liongard (No. 437, 246 percent growth), and Stratus Medical LLC (No. 483, 212 percent growth) also made the list, which is an annual ranking of the fastest-growing North American companies in technology, energy tech sectors, telecommunications, life sciences, media, and fintech.

"Houston continues to demonstrate its prowess in fostering growth and technological advancement and I’m incredibly proud to see some of our local companies making significant strides and earning their well-deserved spots on the 2024 Deloitte Technology Fast 500 list,” Houston managing partner at Deloitte Melinda Yee says in a news release.

Award winners were selected based on fiscal year revenue growth from 2019 to 2022.

The companies achieved revenue growth ranging from 201 percent to 153,625 percent over the three-year time frame with an average growth rate of 1,981 percent and a median growth rate of 460 percent, according to a news release. Texas accounts for 6 percent of the winning companies with 73 percent of the companies from Texas are in the software sector.

“These companies exemplify the entrepreneurial spirit and innovative mindset that define Houston's dynamic business ecosystem,” Yee adds.

In 2023, the Houston representation looked similar. Direct Digital Holdings again topped the Houston rankings at No. 108, with Liongard, NatGasHub.com, and P97 Networks also showing substantial growth. As a state, Texas had 30 companies that made the list of the 541 ranked. In 2022, just one Houston company was recognized, as at No. 372 Onit reported revenue increase of 369 percent.

Biopharmaceutical company TG Therapeutics, Inc. was the No.1 spot in 2024 with a growth rate of 153,625 percent from 2020 to 2023. See the full list here.

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.

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.

Rice University launches new venture fund for university-affiliated startups

startup support

Rice University has launched its new One Giant Leap Ventures Fund I, which will invest in the university’s spinouts and alumni-founded startups.

The early-stage institutional venture fund will function with a hybrid structure that allows for participation from traditional equity investors and philanthropic investors. According to the university, the fund will invest up to $500,000 per Rice-affiliated company.

To be considered eligible for funds, companies must use intellectual property licensed by the university or be led or founded by alumni.

One Giant Leap will draw on support and mentorship from Rice’s pool of 60,000 alumni and aims to create educational opportunities within the investment phases, work with graduate and undergraduate venture students, explore the scaling and commercialization of their ideas, and help investigate all the facets of venture capital.

“Rice alumni bring an extraordinary depth of experience as entrepreneurs, investors and industry leaders, and One Giant Leap creates new ways to put that expertise to work for the next generation of Rice innovators,” Stephen Bayer, vice president for development and alumni relations, said in a news release. “It strengthens the connection between our alumni and the university while giving them meaningful opportunities to mentor, advise and support Rice-affiliated companies as they grow.”

The fund held its first close in August and made its first investment into Rice brain health spinout Motif Neurotech. Led by Rice faculty member Jacob Robinson, Motif is working to commercialize a minimally invasive neurostimulator that targets treatment-resistant depression. In May, the FDA approved the company to move forward with its first clinical trial.

“Research produces breakthrough technologies and our academic environment forms outstanding entrepreneurs,” said Adrian Trömel, the fund’s managing director, a Rice alumnus and a startup founder who also serves as Rice’s interim chief innovation officer.

One Giant Leap joins the already long list of Rice-led programs that foster innovation, including the Liu Idea Labs for Innovation and Entrepreneurship’s Innovation Fellows and Summer Venture Studio, the Rice Alliance’s Business Plan Competition, the Ion District, Woodside Rice Decarbonization Accelerator, Rice Nexus, the Biotech Launchpad and RBL Ventures and its upcoming 200,000 square-foot research lab the Arc.

“With One Giant Leap, I am excited that we are creating a unique structure that brings together traditional investment and philanthropic participation to invest in and help catalyze our startups, engage the deep expertise within the Rice ecosystem and transform those strengths into real-world impact,” Trömel added in the release.

New statewide plan aims to eliminate cervical cancer in Texas by 2032

fighting cancer

MD Anderson, on behalf of a coalition of health systems, has announced a new plan to eliminate cervical cancer in Texas.

The five-year Texas Lone Star Cervical Cancer Elimination Plan was launched during the Cancer Prevention and Research Institute of Texas (CPRIT) 2026 Innovations Conference in Galveston this month.

The plan focuses on three major pillars with goals to be achieved by 2032:

  • HPV vaccination: Increase the percentage of Texas boys and girls up to date on human papillomavirus (HPV) vaccination by age 15 from 50.5 percent to 80 percent
  • Cervical cancer screening: Raise the share of Texas women up to date on cervical cancer screening from 64 percent to 80 percent
  • Timely follow-up, diagnosis and treatment: Ensure 80 percent of women receive diagnostic follow-up and treatment when needed through community outreach, patient navigation, provider training and survivorship support

Overall, the coalition wants to see fewer than four new cases of cervical cancer annually per 100,000 Texas women by 2032, according to a news release from MD Anderson. Currently, Texas has an incidence rate of 9.5 women per 100,000 diagnosed with cervical cancer, compared with 7.5 women per 100,000 nationally.

“Texas has the tools to prevent nearly every case of cervical cancer, but tools can save lives only when people can utilize them,” Dr. Ernest Hawk, vice president and division head of Cancer Prevention and Population Sciences at MD Anderson, said in the release. “The Lone Star Cervical Cancer Elimination Plan gives us a shared roadmap to vaccinate more of our children, screen more of our women and make sure every abnormal result leads to care. With innovations like HPV self-collection and the commitment of partners across the state, elimination is within reach.”

About 40 other hospitals, health care organizations and companies join MD Anderson in the coalition that launched the Lonestar Plan. Those based in Houston include Houston Methodist, Rice University, UTHealth Houston, Texas Children's Hospital, Houston Health Department and others.

The CPRIT also announced its Texans Conquer Cancer Awards and its CPRIT Champion awards during the Innovations Conference this week. Several are based in Houston, including:

  • Zhiqiang An, co-founder of CrossBridge Bio, Director of the Texas Therapeutics Institute, and Vice President of Drug Discovery at the University of Texas Health Science Center at Houston
  • Dr. Abbey Berenson, Director of the UTMB Center for Interdisciplinary Research in Women's Health Care
  • Dr. Michael Taylor, Chair of Pediatric Neuro-Oncology at Texas Children's Cancer and Hematology Center and Director of Texas Children's Pediatric Brain Tumor Research Program

To date, the CPRIT has awarded more than $4.2 billion in grants to fight cancer in the state. Over the summer, it awarded four $2 million grants to institutions in Houston and Bryan for the creation or expansion of “core” cancer research facilities.

Texas Medical Center Innovation recently announced that its $2 million grant would renew its Accelerator for Cancer Therapeutics for five years. Read more from TMCi about the renewal here.
