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.

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.

Houston investment firm closes $105M energy venture fund

seeing green

Houston-based investment firm Veriten has announced the initial close of its second flagship energy venture fund with more than $105 million in capital commitments.

Fund II will build on Veriten’s initial fund and aim to support “scalable technology solutions for energy, power and industrial applications,” according to a company news release.

"Our differentiated network, research-driven process, and first principles approach to investing are having an impact across multiple verticals including traditional energy, electrification, and industrial technology. Fund II builds on that platform,” John Sommers, partner, investments at Veriten, added in the release. “In this environment, the differentiator isn't capital – it's all about connectivity, deep sector expertise, and an economically-driven approach. As new technologies and approaches develop at breakneck speed, the need for more reliable, affordable energy and power continues to grow dramatically. The current backdrop accentuates the need for Veriten's solution."

Veriten is supported by over 50 strategic partnerships in the energy, power, industrial and technology sectors, including major players like Halliburton and Phillips 66.

"Veriten continues to build a differentiated platform at the intersection of energy, technology and industry expertise," Jeff Miller, chairman and CEO of Halliburton, said in the release. "We were early believers in the team and their ability to identify practical solutions to real challenges across the energy value chain. As all industries increasingly adopt digital tools, automation and AI-enabled technologies to improve performance and execution, we are proud to partner with Veriten again to help accelerate high-impact solutions across the broader energy landscape."

Veriten closed its debut fund, NexTen LP, of $85 million in committed capital in October 2023. It was launched in January 2022 by Maynard Holt, co-founder and former CEO of the energy investment bank Tudor, Pickering, Holt & Co.

It has invested in Houston-based AI-powered electricity analytics provider Amperon and led a $12 million Seed 2 funding round for Houston-based Helix Technologies to scale manufacturing of its energy-efficient commercial HVAC add-on earlier this year. In the past year it has contributed to funding rounds for San Francisco-based Armada and Calgary-based Veerum.

Veriten also named Nick Morriss as its new managing director earlier this month. Morriss most recently served as vice president of business development at next-generation nuclear technology company Natura Resources and spent nearly 20 years at NOV Inc.

Here's how Houston ranks among the best U.S. cities to start a career

New Horizons

College graduates staying in Houston are in the right place to be, according to a new WalletHub study. Houston has emerged on a new list of the 100 best places in America for starting a career.

Houston ranked 51st out of 182 U.S. cities based on its quality of life and vast opportunities for new college graduates transitioning into the workforce. The study compared each city based on 25 relevant metrics, like the availability of entry-level jobs, each city's annual job growth rate, workforce diversity, median annual income, housing affordability, and others.

Atlanta, Orlando, and Austin respectively comprised the top three best places to start a career.

Houston ranked 48th overall for its quality of life, and appeared No. 51 for its professional opportunities for new college graduates. Whether its starting a new business or entering a high-earning job field, Houston has many more opportunities than the vast majority of other cities on the list.

"The best cities for starting a career not only have a lot of job opportunities but also provide substantial income growth potential and satisfying work conditions," said WalletHub analyst Chip Lupo. "It’s also important to consider factors such as how fun a city is to live in or how good of a place it is for raising a family, to ensure life satisfaction outside of your career."

Other Texas hotspots for early career professionals
Austin boasts the best quality of life out of all 182 cities in the report, and the 10th best professional opportunities. The state capital also outperformed all other U.S. cities with the highest monthly average starting salaries for early career workers after being adjusted for the city's cost of living. Austin also offers the 15th highest number of entry level jobs per capita, the report said.

In a separate comparison of the cities with the largest share of residents aged 25 to 34, Austin ranked No. 5 nationally.

"In addition, Austin’s median annual household income is the 10th-highest in the nation, providing strong earning potential for those starting a career or a business," the report said. "Austin is also the sixth best city for singles, offering a vibrant social scene alongside strong career opportunities for young professionals."

Elsewhere in Texas, Dallas ranked as the second-best city in Texas for new grads to start a career and 12th nationally. Additional cities that made it into the top 100 best U.S. cities for early career professionals include Plano (No. 32), Irving (No. 42), Fort Worth (No. 64), Amarillo (No. 73), and San Antonio (No. 85).

The top 10 best cities for starting a career are:

  • No. 1 – Atlanta, Georgia
  • No. 2 – Orlando, Florida
  • No. 3 – Austin, Texas
  • No. 4 – Tampa, Florida
  • No. 5 – Miami, Florida
  • No. 6 – Charleston, South Carolina
  • No. 7 – Pittsburgh
  • No. 8 – Knoxville, Tennessee
  • No. 9 – Salt Lake City, Utah
  • No. 10 – Columbia, South Carolina

Persona AI teams with Under Armour to protect next-gen robots

Future Fabrics

Houston-based Persona AI has cemented a partnership with sportswear manufacturer Under Armour to provide materials to protect future robots operating in dangerous conditions.

Through the partnership, Persona AI and Under Armour will launch a research initiative to explore whether advanced performance textiles can improve the durability and resilience of humanoid robots operating in harsh industrial environments.

“This is an opportunity to apply our innovation expertise in a new context,” Kyle Blakely, senior vice president of innovation, design studio, development, and testing at Under Armour, said in a news release. “Robotics presents a fascinating new design challenge, and we aim to play a leading role in shaping performance solutions for these environments. As humanoid systems take on more physically demanding roles, we see real potential to create new market opportunities, and we’re exploring how concepts like thermal management, abrasion resistance, and flexibility translate beyond sport."

Founded in June 2024 by former NASA engineer Nicolaus Radford and former Figure AI CTO Jerry Pratt, Persona AI has quickly risen to be a top name in the development of humanoid robotic systems. Radford previously was the principal investigator at NASA’s Dexterous Robotics Lab before becoming CEO of Nauticus Robotics. While at NASA, he was the chief engineer behind Robotnaut 2, the first humanoid robot on the International Space Station.

Persona AI raised preseed funding to develop humanoid robots designed to operate in shipyards and other industrial sites. The company has inked partnerships with HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Robotic, and Korean manufacturing firm Vazil Company to create and deploy humanoid robots for complex welding tasks in shipyards.

These environments often involve exposure to dangerous chemicals, harsh weather and other potential hazards. The partnership between Persona AI and Under Armour will combine the clothing manufacturer’s development of resilient but flexible materials with the humanoid design of Persona AI.

Though best known for its sportswear, Under Armour produces a wide range of specialist fabrics and clothing, including an entire line used by the U.S. military. The company’s track record of developing high-performance fabrics built to withstand war zones and desert conditions makes it a strong partner in Persona AI’s latest endeavor.

“We chose to work with Under Armour because of their track record of innovation with these types of performance materials,” Radford said. “As we develop humanoids for intense and potentially hazardous environments, this collaboration helps us understand how advanced materials can enhance long-term reliability, thereby informing solutions to better protect workers in the field.”
