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.”

ready, set, grow

Bellaire-based startup Instafuel is pumping up its revenue in a big way.

Among the 250 fastest-growing companies in Texas identified by Inc. magazine, Instafuel tops the group of businesses based in the Houston metro area and ranks fifth statewide. Houston-based companies make up 68 of the state's fast-growing companies — eight Houston companies make up the top 25 list.

Instafuel, whose official corporate name is Fuel Husky LLC, provides mobile refueling services to B2B clients. The Inc. ranking, released March 13, shows Instafuel posted revenue growth of 1,353 percent from 2016 to 2018.

According to a November 2019 article published by CSP magazine, Instafuel has expanded to 30 trucks that have dispensed nearly 10 million gallons of fuel to more than 150 B2B clients in major Texas metro markets like Houston, Dallas-Fort Worth, and Austin. CSP covers the convenience and petroleum retailing industry.

"We've been bootstrapping … in stealth mode for the last four years, just trying to grow this business one [client] by one, trying to truly understand what it means to be a mobile refueler, or what we call a compact mobile refueler, and trying to target and understand the business model for small- to medium-sized business fleets," Nour Baki, vice president and co-founder of Instafuel, told the magazine.

Ranked second in the Houston area and sixth statewide by Inc. is Spring-based Bellatorum Resources LLC, whose revenue shot up 1,261 percent from 2016 to 2018. Bellatorum, a veteran-owned and veteran-operated investment company, specializes in mineral rights and oil royalty acquisitions.

"I think our work ethic and customer service is what makes us different from our competitors," Chris Bentley, president and CEO of Bellatorum Resources, told the Oil & Gas Council in July 2018.

"Based on the feedback I consistently receive from mineral owners, they tell me that many of our competitors fail to return phone calls and emails, and sometimes even fail to treat them with common courtesy and respect during their business dealings," Bentley added. "We believe in putting the mineral owner first, which always pays off for us."

At No. 3 in the Houston area and No. 8 statewide is Houston-based Sarvicus LLC. Sarvicus, an IT services and utilities provider, grew revenue by 1,048 percent from 2016 to 2018.

"Whether it's a process, piece of equipment, or a tool, we try to optimize its efficiency. When we are successful, that often translates to benefits for our customers," Sarvicus co-founder and CEO Marc Packard told CIOReview magazine.

Houston-based SIA Solutions LLC appears at No. 4 among Houston-area companies and No. 9 among Texas companies. From 2016 to 2018, revenue at the professional services engineering and consulting firm soared 1,030 percent.

"Because of our client-first philosophy, we're willing to take on tough challenges and deliver. It's in our culture. It's natural to us," CEO Srini Neralla told the McFerrin Center for Entrepreneurship at Texas A&M University's Mays Business School in November 2019. We put together strong teams comprising of firms our size or larger, including universities, in order to deliver what our clients want."

With a 2016-18 growth rate of 824 percent, Houston-based Zahroof Valves Inc. nails down the No. 5 spot among Houston-area companies and No. 14 among Texas companies. Zahroof Values makes and markets specialized valves for reciprocating gas compressors. Its investors include Saudi Aramco Energy Ventures LLC, the investment arm of oil giant Saudi Aramco.

In an August 2019 release, Zahroof Valves CEO Tony Gioffredi said: "Our commitment to driving positive change [in] the oil and gas industry is shown through our innovative products … ."

Houston scientist wins prestigious Pew Scholar award for brain cancer research

standout scholar

Christina Tringides, an assistant professor of materials science and nanoengineering at Rice University, is one of 21 scientists to win a prestigious Pew Biomedical Scholar award.

She is the first faculty member from Rice to win the distinction, which provides $300,000 over four years for advances in biomedicine, according to the university. The awards are granted to researchers who are in the first few years at the assistant professor level.

In Tringides’ case, the funding will support her innovative new method of modeling glioblastoma, a common and extremely aggressive form of brain cancer. Thanks to producing its own blood supply, glioblastoma spreads quickly, weaving tendrils of blighted tissue throughout the brain. Because of this, surgery is difficult and conventional therapies ineffective.

Understanding the way glioblastoma spreads is crucial to the search for a cure. Tringides is using hydrogels that mimic the brain’s extracellular matrix. Using cultures and a microscopic labyrinth, her team can see how the cancer spreads, bonds with neurons and changes cell wall activity. Essentially, Tringides has devised an intelligence test for tumors in hopes of learning how to outsmart them.

“As cancer crawls through the maze, we can look at how it is interacting with the neurons more and more, and measure how electrical activity is changing as a result,” she said in a news release from Rice.

Examining how cancer cells grow can reveal which conditional changes slow them down. Finding ways to alter the structure of brain matter in a way that makes it inhospitable to the cancer could lead to therapies that would impede growth or even reverse it. Using her custom-made ersatz brain maze makes it easier to observe changes than it would be in a patient’s brain.

“Imaging synapses is time-intensive ⎯ it can involve large data files that are hard to visualize, but if we know that the only place where we might have a synapse is this tiny 1-by-4-by-10 micron channel, it makes it much faster and reliable to image them,” Tringides said.

Born in Ames, Iowa, Tringides received her doctorate in biophysics from Harvard before joining Rice in 2024 through a Cancer Prevention and Research Institute of Texas (CPRIT) recruitment award.

Her research was also one of the first four projects to receive research awards through the Rice Brain Institute and TMC Neuro Collaboration Seed Grant Program.

Texas residents earn 11th highest income in U.S., says 2026 study

Money Matters

A new WalletHub study comparing income disparities across America has ranked Texas residents No. 11 on the list of states with the highest earning residents in the nation.

The report, "States Where People Have the Highest Income (2026)," analyzed U.S. Census Bureau income data in all 50 states and the District of Columbia. The report evaluated the average annual income of the top five percent, the median annual household income, and the average annual income of the bottom 20 percent of residents in every state, all adjusted for the cost of living.

The report's data revealed the top five percent of Texans, the highest earners, make $520,378 on average yearly after adjusting for the cost of living. That's the seventh-highest income among the top five percent of earners nationwide.

Meanwhile, the median annual income of a Texas household is just under $76,000. The bottom 20 percent of Texas residents make $17,651 a year, the report found.

For additional context, the latest data from the Federal Reserve shows an American household's median yearly income is about $83,700. WalletHub analyst Chip Lupo also found that the highest earning 10 percent of individuals in the U.S. earn over 12 times more than those in the lowest-earning 10 percent, based on the latest Census data.

"By measuring the income of various percentiles against a state's median income, we can better identify where income disparities are more prevalent, which could help us better understand why residents of certain states struggle more to make ends meet," said Lupo.

Virginia is the state where residents earn the highest income in the U.S., WalletHub said. Based on the report's findings, the top five percent of Virginians make $545,097 on average per year after adjusting for the cost of living. The median annual income of a Virginia household comes out to $95,339, and the bottom 20 percent of residents make $19,671 annually on average.

Conversely, West Virginia is the state where people have the lowest income in the U.S. A West Virginia household makes a median annual income of $56,610, the third-lowest nationally, and the bottom 20 percent of residents make $13,260 on average per year, which is the fifth-lowest in the nation. The top five percent of West Virginians make $372,218 on average per year.

The top 10 states where residents have the highest income are:

  • No. 1 – Virginia
  • No. 2 – New York
  • No. 3 – New Jersey
  • No. 4 – Washington
  • No. 5 – Connecticut
  • No. 6 – Utah
  • No. 7 – Colorado
  • No. 8 – Minnesota
  • No. 9 – Illinois
  • No. 10 – Massachusetts

23 Houston companies rank among America’s most future-ready businesses

future focused

By one measure, Spring-based tech giant Hewlett Packard Enterprises reigns as the most future-ready Houston-area company on the S&P 500 stock index.

HPE sits at No. 72 in a first-time ranking of the best S&P 500 companies for the future. Including HPE, 23 Houston-area companies appear on the list.

Published by The Wall Street Journal, the ranking was created by Bendable Labs for the WSJ Leadership Institute. It evaluates how S&P 500 companies stack up in six areas: AI readiness, innovation, talent readiness, financial fitness, resilience and agility. To be ranked, a company had to be part of the S&P 500 as of Dec. 31.

Among the six categories, HPE ranked highest for innovation (No. 30) among local companies. The WSJ didn’t say why HPE scored so well for innovation. However, the company stands out in this category thanks to:

  • Creation of the El Capitan and Frontier supercomputing systems
  • Research into photonic computing and quantum networking
  • Last year’s $14 billion acquisition of Juniper Networks, giving HPE an edge in AI-native networking
  • Establishment of the everything-as-a-service GreenLake hybrid cloud platform for data centers, colocation facilities and edge computing environments

In an interview with the Six Five podcast at HPE Discover 2025 in Las Vegas, CEO Antonio Neri said the company’s strategy is “basically founded on innovation, and that innovation drives shareholder value over the long term.”

While HPE fared well in the innovation category, it ranked toward the bottom for financial fitness. What’s behind the No. 430 ranking in the financial category? HPE’s low score likely reflects a debt-heavy acquisition strategy coupled with a historically low-margin hardware business.

Here’s the full list of the 23 Houston-area companies included in the ranking of the best companies for the future:

  • No. 72 Hewlett Packard Enterprise
  • No. 105 SLB
  • No. 120 Baker Hughes

  • No. 158 NRG Energy
  • No. 176 Targa Resources
  • No. 185 Chevron
  • No. 195 Halliburton
  • No. 223 Coterra Energy
  • No. 229 Waste Management
  • No. 235 Exxon Mobil
  • No. 250 Kinder Morgan
  • No. 257 Quanta Services
  • No. 276 CenterPoint Energy
  • No. 285 Sysco
  • No. 313 Occidental Petroleum
  • No. 318 Camden Property Trust
