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.

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.

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 clean energy to software — recently making headlines in Houston innovation.

A few years ago, Rice Management Company saw an opportunity a few years back to make an investment in Houston's nascent innovation and tech ecosystem, and announced the plans for the Ion, a 266,000-square-foot innovation hub in an renovated and rehabilitated Sears.

"In some ways innovation is not necessarily about creating something completely new — it's oftentimes building upon something that exists and making it better," says Sam Dike, manager of strategic initiatives at Rice Management Company, on the most recent episode of the Houston Innovators Podcast. "I think that's what we've done with the building itself.

"We took something that had really strong bones and a strong identity here in Houston," he continues, "and we did something that's often atypical in Houston and preserved and repurposed it — not an easy logistical or financial decision to make, but we believed it was the best for Houston and for the project."

In her previous role at Chevron, she spearheaded the energy company's support of Greentown Labs since 2013 and the opening of its Houston incubator. After announcing her retirement in December, she has continued being active at Greentown and hosts semi-annual Women of Greentown Houston dinners.

“I am honored and excited to join the Greentown Labs Board of Directors,” says Burger in the release. “Combatting the effects of climate change requires bringing a wide range of innovative solutions to scale. There is work for incumbents and startups alike in this enormous challenge that WE all face. Greentown Labs plays an essential role in providing facilities, tools, programs, and an inclusive community to nurture and grow innovation that matters.” Click here to continue reading.

Houston team develops innovative soft skeleton for kids with cerebral palsy

health tech

A team from the NSF University of Houston Building Reliable Advances and Innovation in Neurotechnology (UH BRAIN) Center and TIRR Memorial Hermann has introduced the MyoStep soft exoskeleton for children with cerebral palsy, according to a news release from UH.

The soft skeleton aims to address motor impairments caused by cerebral palsy that impact children’s ability to participate in physical activities, self-care and academics.

“The MyoStep project represents a significant advancement in the field of pediatric mobility aids, particularly for children with cerebral palsy,” Jose Luis Contreras-Vidal, director of UH BRAIN and the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering, said in a news release.

The next-generation lightweight, soft exoskeleton was funded by the IEEE Electron Devices Society (EDS) Award.

The MyoStep is made to be lightweight and discreetly fit under clothes. It includes a wireless sensor network embedded inside the smart and flexible fabrics that is the backbone of the suit and collects and sends real-time data about the user’s movements It also includes safety features with temperature monitoring and emergency shut-off mechanisms.

“By integrating cutting-edge technologies such as artificial muscles, smart fabrics, and a comprehensive sensor network, MyoStep offers a promising solution to the challenges faced by existing exoskeletons,” Contreras-Vidal said in a news release.

Cerebral palsy is a neurological disorder that impacts motor skills. It occurs in one to four out of every 1,000 births worldwide.

“What makes the MyoStep project so compelling is that it’s not just about the technology: it’s about restoring confidence, function, and hope,” Dr. Gerard Francisco, a clinical partner on the technology, The Wulfe Family Chair of Physical Medicine and Rehabilitation at UTHealth Houston and medical officer at TIRR Memorial Hermann, said in a news release. “This kind of innovation has the potential to dramatically improve quality of life, helping children move through the world with greater ease and dignity.”
