Four Houston businesses made the cut on Deloitte's recently unveiled list of the fastest-growing technology companies in North America — and two are energy tech companies.

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.”

Houston's two energy representatives are NatGasHub.com, a pipeline data source, at No. 356 with 364 percent growth and P97 Networks, a fintech company for gas stations, at No. 506 with 225 percent growth.

The other two Houston businesses are digital media company Direct Digital Holdings at No. 108 with 1,325 percent growth and B2B software solutions business Liongard at No. 208 with 680 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.
