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.

Q&A: Newly named Houston corporate energy, chemicals leader on navigating dynamic energy transition sector

Featured Innovator

Deloitte is undergoing a leadership shift — and this evolution for the nearly 200-year-old company directly affects its Houston office and the energy transition line of business.

Earlier this year, Teresa Thomas was named vice chair and national sector leader for energy and chemicals at Deloitte. Based in Houston, she will also serve as an advisory partner and leader in Deloitte & Touche LLP's Risk & Financial Advisory energy and chemicals practice. She succeeds Amy Chronis, partner at Deloitte LLP, who will continue to serve within the energy and chemicals practice until her retirement in June 2024.

In an interview with EnergyCapital, Thomas shares a bit about what she plans on focusing as she takes on her new role.

EnergyCapital: As you transition into your new role, how would you describe your focus and priorities?

Teresa Thomas: I am excited about what lies ahead for the energy and chemicals sector. The sector is moving into the new year with strong production and a focus on returning value and achieving efficiency. The sector is innovating with new technologies, such as artificial intelligence, including generative AI. that can capture value from data to transform and reinvent business processes and optimize the workforce.

The mission for my leadership role is to grow our practice by serving our clients with world-class solutions; venture into new innovative areas that exceed the changing needs in our sector; and attract, retain, and develop the best talent across Deloitte’s four businesses. I am bullish about the sector's role in leading on the forefront through the energy transition, pioneering innovative technologies and solutions that will help solve some of society’s most pressing issues, and contributing unique and differentiated ideas to help transform the energy and chemicals sector to meet global demands in a sustainable and profitable way.

EC: How is Deloitte navigating the trends and progression of the energy transition? What are clients’ expectations, and how does the company plan to stay a step ahead?

TT: At Deloitte, we proactively navigate the dynamic landscape of the energy transition with a strategic, collaborative, and innovative edge. Our extensive global presence and diverse partnerships, spanning industries, regions, and academic institutions, keep us abreast of emerging trends, regulatory shifts, and technological advancements. Client expectations are evolving towards sustainable practices, and we respond by providing innovative solutions that align with their goals.

Our commitment to staying a step ahead involves continuous investment in talent development and innovative technologies. Central to our strategy is taking ownership of pivotal marketplace issues and adeptly guiding clients through the intricacies of their business challenges. Through harnessing our extensive expertise that cuts across our four business, we aim to create growth opportunities and offer innovative solutions.

EC: Energy companies have been known to more slowly adopt and adapt to new technologies. Is that changing?

TT: We believe the energy and chemicals industries is at the forefront of adopting cutting-edge technologies to bolster operational efficiency, increase productivity, reduce costs, and advance safety and sustainability measures. From bringing new materials to consumers, pioneering offshore operations, transforming shale resources into one of the most competitive resources, to developing new and sustainable molecules, the industry has highlighted its adaptability. The industry continues to be a leader of groundbreaking technologies including the development of biofuels, biomaterials, carbon capture, hydrogen production, and more.

Additionally, energy companies are increasingly leveraging digital technologies, including GenAI to enhance operational efficiency, optimize resource management, and drive innovation across various segments of the industry. From interpreting seismic data and predicting reservoir behavior, to employing carbon analytics and tracking GHG emissions, the industry is transforming its operations and contributing to a more sustainable and efficient energy landscape. While there is much more to be done, we remain confident that the energy industry will continue to help lead the way in innovation.

The oil and gas industry has been increasingly investing in clean energy over recent years, wherein the clean energy investments by the oil and gas industry as a share of their upstream capex quadrupled between 2020 and 2022. Yet, this clean energy investment remains less than 2 percent of the overall clean energy investments made in 2022.

After having outperformed the broader S&P 500 by over 45 percent since 2021, the oil and gas industry faces a threefold mandate:

uphold financial stability,
sustain high dividends, and
augment investments in low-carbon ventures.

However, the central challenge lies in scaling the energy transition while maintaining profitability and shareholder value.

EC: The chemicals sector, in particular, seems ripe for disruption with new and developing alternative materials on the scene. What do you expect to see from this industry in 2024?

TT: There is a chemicals and material transition taking place as companies are pushed to develop more sustainable, lower-carbon materials. And given that 96 percent of all manufactured goods are touched by chemistry, this transition could also be transformational. Over the next year, we expect chemical companies to continue positioning themselves for this high-tech, low-carbon future in three notable ways.

First, we expect companies to increase automation and digitalization to improve productivity and accelerate innovation.
Second, we see companies continuing to invest in circular solutions, whether it's designing materials for a sustainable end-of-life or using renewable feedstocks.
Third, we expect some companies to lean into the new chemicals and materials needed to support the energy transition.

EC: As a Houstonian, what do you see the city’s role amidst the future of energy?

TT: Houston is a top global city, driving transformational change and a convener to an ecosystem of players that are leading the charge in the energy transition through biofuels, biomaterials, and advanced methods for carbon capture and hydrogen production.

Although not a native, I did find the energy and chemicals sector early in my career which brought me to this dynamic city. Houston’s advanced network of partners are working together toward creating innovative solutions that are accelerating the advancement of a lower carbon future.

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.

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.

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.

Whatever the future holds, it’s a sure bet that health tech will remain a strong sector that attracts investors. Photo via Getty Images

How a shifting business model in Houston can keep health tech attractive to investors

guest column

Investment in health tech, in Houston and nationwide, took off in 2021. Despite a dip in funding in 2022, the sector is hardly losing its luster. In fact, it continues to attract investor attention as it evolves into a more mature, and equally exciting, market.

Health tech is especially vibrant in Houston. With a strong life sciences ecosystem, Houston is home to Texas Medical Center – the world’s largest medical research complex. That ecosystem is set to become even stronger with the completion of TMC’s Helix Park, a 37-acre life sciences campus, later this year. Couple this with analysis suggesting that Houston is the country’s third fastest-growing tech ecosystem and the future looks promising.

Houston is currently home to 339 health tech startups, according to Tracxn, ranging from companies that make apps to track cognitive health to those offering solutions for chronic disease management, and initiatives are in place to help grow the depth and breadth of that bench. For example, Texas Medical Center Innovation helps health-tech startups launch and build relationships with the state’s medical community. And, Houston Methodist has announced plans to build a digital health technology hub at The Ion, the tech-focused office and collaboration space that serves as the anchor to Houston’s innovation district.

Deloitte recently released a new Health Tech Investment Trends Report, based on data analysis of venture-capital deals in health tech, as well as interviews with investors and startup executives. The findings indicate several key shifts affecting health-tech companies and startup scenes, both here in Houston and nationwide. Namely, changes are occurring in three discrete areas: in investors’ area of focus, in the type of health challenges startups are addressing, and in the creation of a new business model for health-tech companies.

Investors seek stability. Nationwide, funding for health-tech startups dipped to $27.5 billion in 2022 from $39.3 billion in 2021, a decline of 30 percent. To be sure, a 30 percent drop in anything can cause concern, but here, it’s an indication that investors are putting more money into older, more established companies – late-stage companies received 75 percent of investments in 2022 – rather than growth companies. In Houston, startup funding overall in the first quarter of 2023 totaled $106 million across five deals, with health-tech startups nabbing 20 percent of the pie, and with an average of $21.2 million per deal.

Startups refocus. Health-tech entrepreneurs are moving away from telehealth and general mental health and moving towards specific mental-health areas, for instance those directed toward certain populations such as the elderly or women. Health equity is front and center, with both diverse founders and solutions for diverse communities attracting attention. Companies offering back-office efficiencies to healthcare providers are also garnering investor interest.

Business models shift. The news here: Toward platforms and away from pipelines. Many traditional businesses use the pipeline model. They create products and deliver them to end users, handling manufacturing, marketing, and distribution along the way. A platform model works a bit differently. It creates the product, then establishes a network of users and partners who exchange information and resources and work together to deliver products and services to the end user.

Investors seem to like platforms, as eight of the top 10 later-stage companies funded in 2022 utilize this platform model, according to Deloitte’s analysis of Pitchbook’s Health Tech Funding Database. The platform ecosystem also may be the way our healthcare system can transform from one that reacts to one that focuses on prevention and wellbeing.

In the near future, a few factors might further shape this health-tech evolution. Macroeconomics, for instance, could put more emphasis on unit economics at startups. Startups that previously sold their services to employers may increasingly look at healthcare systems as potential customers. Whatever the future holds, it’s a sure bet that health tech will remain a strong sector that attracts investors.

Rice University MBA programs rank among top 5 in prestigious annual report

top of class

Rice University’s Jones Graduate School of Business MBA programs have been ranked among the top five in the country again in The Princeton Review’s 2025 Best Business Schools rankings.

The university's MBA program in finance earned a No. 3 ranking, climbing up two spots from its 2024 ranking. Finance MBA programs at the University of Virginia's Darden Graduate School of Business and New York University's Leonard N. Stern School of Business were the only ones to outrank Rice, claiming No. 2 and No. 1 spots, respectively.

Rice's online MBA program was ranked No. 5, compared to No. 4 last year. Indiana University's Bloomington Kelley School of Business' online program claimed the top spot.

“These rankings reflect the commitment of our faculty and staff, the drive and talent of our students and the strong support of our alumni and partners,” Peter Rodriguez, dean of Rice Business, said in a news release. “They are exceptional honors but also reminders — not just of our top-tier programs and world-class faculty and students but of our broader impact on the future of business education.”

Rice also ranked at No. 6 for “greatest resources for minority students."

The Princeton Review’s 2025 business school rankings are based on data from surveys of administrators at 244 business schools as well as surveys of 22,800 students enrolled in the schools’ MBA programs during the previous three academic years.

"The schools that made our lists for 2025 share four characteristics that inform our criteria for designating them as 'best': excellent academics, robust experiential learning components, outstanding career services, and positive feedback about them from enrolled students we surveyed," Rob Franek, The Princeton Review's editor-in-chief, said in a press release. "No b-school is best overall or best for all students, but to all students considering earning an MBA, we highly recommend these b-schools and salute them for their impressive programs."

Rice's finance program has ranked in the top 10 for eight consecutive years, and its online MBA has ranked in the top five for four years.

Rice and the University of Houston also claimed top marks on the Princeton Review's entrepreneurship rankings. Rice ranks as No. 1 on the Top 50 Entrepreneurship: Grad list, and the University of Houston ranked No. 1 on Top 50 Entrepreneurship: Ugrad. Read more here.

Houston named ‘star’ metro for artificial intelligence in new report

eyes on AI

A new report declares Houston one of the country’s 28 “star” hubs for artificial intelligence.

The Houston metro area appears at No. 16 in the Brookings Institution’s ranking of metros that are AI “stars.” The metro areas earned star status based on data from three AI buckets: talent, innovation and adoption. Only two places, the San Francisco Bay Area and Silicon Valley, made Brookings’ “superstar” list.

According to Brookings, the Houston area had 11,369 job postings in 2024 that sought candidates with AI skills, 210 AI startups (based on Crunchbase data from 2014 to 2024), and 113 venture capital deals for AI startups (based on PitchBook data from 2023 to 2024).

A number of developments are boosting Houston’s AI profile, such as:

Apple is opening a 250,000-square-foot factory in Houston that will make servers for its data centers in support of the tech giant’s AI business.
Nvidia has teamed up with Foxconn to build a factory in Houston that will produce AI supercomputers.
Aramco, whose Americas headquarters is in Houston, has signed a preliminary deal with Nvidia to develop advanced industrial AI computing and tackle other AI initiatives.
Rice University is introducing a bachelor’s degree program in AI this fall.

Brookings also named Texas’s three other major metros as AI stars:

No. 11 Austin
No. 13 Dallas-Fort Worth
No. 40 San Antonio

Brookings said star metros like Houston “are bridging the gap” between the two superstar regions and the rest of the country. In 2025, the 28 star metros made up 46 percent of the country’s metro-area employment but 54 percent of AI job postings. Across the 28 metros, the number of AI job postings soared 139 percent between 2018 and 2025, according to Brookings.

Around the country, dozens of metros fell into three other categories on Brookings’ AI list: “emerging centers” (14 metros), “focused movers” (29 metros) and “nascent adopters” (79 metros).
