8 Houston companies earn spots on Fortune's most innovative list for 2025

top honor

Eight Houston companies have been named to Fortune’s third annual list of America’s Most Innovative Companies, joining another 16 from the state of Texas.

The group of 300 companies nationwide was rated based on production innovation, process innovation, and innovation culture, according to Fortune. In partnership with Statista, the magazine considered IP portfolios, employee, expert and customer opinions; and many other factors.

While many of the top-rated companies fell into the tech sector, Fortune reports that health care companies made up the largest portion of the 2025 list. Sixty-three honorees fell into the health care category, including Houston’s top-rated company, Houston Methodist.

Here’s what Houston companies made the list and where they ranked:

No. 35 Houston Methodist
No. 54. ExxonMobil
No. 137 NRG Energy
No. 158 Hewlett-Packard Enterprise
No. 169 BMC Software
No. 175 Texas Children’s Hospital
No. 227 Sysco
No. 268 Chevron

“This award is a true credit to the culture we have created around innovation and the incredible work of Roberta Schwartz, our Chief Innovation Officer, and her team at the Center for Innovation,” Marc Boom, CEO of Houston Methodist, said in a LinkedIn post. “They have really set the tone for how we can use innovation and technology to continue to deliver the highest quality care for our patients.”

Of the 16 companies from Texas, Houston was home to the second-most with eight hailing from the Bayou City. Dallas-Fort Worth claimed the largest number of Texas companies on the list, with 11 headquartered in the metroplex.

Austin is home to only four of the companies on the list, however, companies from the capital city ranked higher on average, with Oracle, Tesla and Dell Technologies claiming the top 3 spots for the state. Beloved Texas grocer H-E-B was the one company to represent San Antonio on the list.

Here's what other Texas companies made the list and where they ranked:

No. 6 Oracle
No. 11 Tesla
No. 14 Dell Technologies
No. 37 AT&T
No. 59 Texas Instruments
No. 89 Charles Schwab
No. 91 McKesson
No. 113 Jacobs Solutions
No. 125 Baylor, Scott & White Health
No. 165 Frontier Communications
No. 201 H-E-B
No. 210 CBRE Group
No. 219 TTEC Holdings
No. 223 GameStop
No. 251 American Airlines Group
No. 271 Caterpillar

California-based tech conglomerate Alphabet Inc. topped the list for the third year in a row, and California companies again represented the majority of companies on the list, according to Fortune. Alphabet, Microsoft, Apple, IBM and Salesforce made up the top five, of which three are headquartered in California.

The 2025 group had a median revenue of $22 billion over the last 12 months, according to Fortune. See the full report here.

Intuitive Machines engineer talks STEM, innovation, and second chances

Innovator Interview

Mario Romero is an assembly, integration, and test engineer at the innovative Houston aerospace company Intuitive Machines. He previously served as a Navy SEAL and an EVA Flight Simulator Specialist at NASA.

Intuitive Machines landed its IM-2 mission on the moon last month, before calling an early end of mission. The company reported that its lunar lander was on its side, preventing it from completing the mission as planned.

Still, the IM-2 mission landed closer to the lunar South Pole than any previous lander, according to NASA. And the company still has plenty of innovative projects in the works.

The company secured about $2.5 million from NASA to study challenges related to carrying cargo on the company’s lunar lander and hauling cargo on the moon. The lander will be used for NASA’s Artemis missions to the moon and eventually to Mars.

“Someone has to do it; in fact, the more the merrier,” Romero says on being part of an innovative culture.

“Competition forces innovation, and if I can be selfish for a moment, I think it’s of particular importance for Intuitive Machines because my extremely capable team is more than worthy of having their place stamped in history. We, as a species, have to strive to become a multiplanetary species. Incidentally, part of the trickle-down effect of innovation often leads to spin-off technology that in some way benefits humanity here on Earth.”

Last year, Romero was awarded the key to the city from his hometown of Vineland, New Jersey, and made it a point in his speech to give kids a chance to succeed in the future.

“I am the product of many chances, secondary, tertiary, and more, given to me,” Romero says. “Many of these were admittedly entirely undeserving. I look back now and recognize that those teachers, judges, police, etc. might have all seen something in me that I couldn’t then see in myself. … This is precisely why I often emphasize giving kids multiple chances. Kids are kids, and you can never fully know how you’re inspiring them in the moment, nor how the chances that you give them will affect the trajectory of their lives.”

Texas is expected to represent nearly 10 percent of future STEM opportunities in the nation, and nine of the 20 biggest employers in Texas are STEM-related.

As STEM has become increasingly popular in high schools and at the university level, and the aerospace industry continues to innovate, it is possible that many young future innovators may take the same path a young Romero did.

“I think it’s natural that when new leaps are made in the STEM fields, and in the aerospace realm at large, the youth in general become galvanized by it,” Romero says.

“It’s exciting and reinvigorating to understand that humanity is on the cusp of the next great adventure. As fantastic and essential as this is, I want to emphasize the importance of the arts as well. It has an important place and an important role to play in our evolution, so I personally don’t limit youthful interest to STEM alone. There are fantastic works of art awaiting us, in all their variety, that will come as a result of the efforts and innovation.”

18 Houstonians land on Forbes world's billionaires list for 2025

World's Richest

The world’s richest people are wealthier now than they've ever been, and more billionaires have made it onto the 2025 World's Billionaires List than ever before, according to Forbes. This year, 18 Houston-based billionaires are among the richest people in the world, with hospitality honcho Tilman Fertitta leading as the richest Houstonian.

Fertitta, 67, ranked No. 220 overall with an estimated net worth of $11.3 billion, which steadily increased from his 2024 net worth of $9.4 billion.

In addition to owning the Houston Rockets, the busy billionaire owns Texas-based hospitality and entertainment corporation Landry's, and he authored a book about business leadership in 2019. He most recently was nominated as the new United States ambassador to Italy by President Donald Trump.

Forbes declared Musk the first person to reach the $300 billion status. His current net worth stands at $342 billion, which is a staggering $147 billion more than his 2024 net worth.

"It’s another record-breaking year for the world’s richest people, despite financial uncertainty for many and geopolitical tensions on the rise," said Forbes senior editor of wealth Chase Peterson-Withorn. "And, from Elon Musk to Howard Lutnick and the other billionaires taking over the U.S. government, they’re growing more and more powerful."

In Dallas-Fort Worth, Walmart heiress Alice Walton became the wealthiest woman in the world in 2025. Forbes declared Walton's net worth at $101 billion, which is $28.7 billion more than her 2024 net worth of $72.3 billion. She is now one of 15 individuals to claim 12-figure fortunes, also known as the "$100 Billion Club."
