Missouri has the Busches. Nebraska has the Buffetts. New York has the Hearsts. These are among the best-known wealthy families in the U.S.

Lesser-known nationally but well-known in Texas is the Duncan family of Houston, identified by FamilyMinded.com as the richest family in Texas. The website, which rounded up a list of the richest family in each state, pegs the family's estimated net worth at $26 billion; Forbes puts it at $25.6 billion.

The Duncan family comprises the four children of the late pipeline mogul Dan Duncan.

The children — Dannine Avara, Scott Duncan, Milane Frantz, and Randa Williams — inherited a tax-free $10 billion share of their father's estate following his death in 2010, when the so-called "death tax" had temporarily been repealed, according to Forbes. Each of them has an estimated net worth of $6.4 billion, Forbes says.

Williams is perhaps the most visible of the four Duncan heirs.

Williams is the only Duncan sibling who's involved in running the family business. She is chairwoman of Houston-based Enterprise Products Partners LP, the pipeline company that her father founded in 1968. Last year, the company posted revenue of $36.5 billion. In June, Williams made a big splash with her purchase of Austin-based Texas Monthly magazine.

While the Duncans are worth close to $26 billion, their wealth doesn't come close to that of Alice Walton of Fort Worth, the richest person in Texas. Forbes estimates her net worth at $52.4 billion.

FamilyMinded.com lists Alice Walton and her fellow heirs to the Walmart fortune as the richest family in Arkansas (where Walmart is based), with an estimated net worth of $163 billion. They're also the richest family in the U.S.

For the second time in three years, Texas Monthly has a new owner. But if Randa Duncan Williams — energy exec and heiress worth over $6 billion — has anything to say about it, she'll be the last new owner of the magazine. Duncan Williams — who acquired the magazine by way of a privately held company, Enterprise Products Company, that's a subsidiary of Enterprise Products Partners, the company her late father founded — says she wants to own the magazine "forever." Read the full story here.

Media on media

For the second time in less than three years, Texas Monthly has a new owner. Randa Duncan Williams, chairman of Houston-based midstream oil and gas company, Enterprise Products Partners LP, has purchased the Austin-based magazine. The terms of the sale were not disclosed.

The magazine will become a part of Enterprise Products Company (EPCO), "a privately held company which owns interests in commercial real estate and ranching, as well as a substantial interest in Enterprise Products Partners L.P., a publicly traded midstream energy company," says a release.

"I have been an avid Texas Monthly reader since I was a teenager," says Duncan Williams, chairman of Texas Monthly, LLC, and of EPCO, in the release. "My family is delighted to provide the resources to support this iconic Texas institution which is nationally recognized for its editorial flair."

Williams is the daughter of EPP's late founder, Dan L. Duncan. She has a net worth of $6.2 billion, according to Forbes.

In TM's official statement, president Scott Brown is quoted as saying Duncan Williams wants to own the magazine "forever."

Forever may be what the magazine needs, following a tumultuous era for Texas Monthly, considered to be both a beacon of Texas culture and a shining example of long-form magazine journalism. In 2016, it was purchased from Emmis Communications by Genesis Park, a private investment firm led by Paul Hobby of the famed Houston-based Hobby family. Following that purchase, Hobby took over the role of chairman and CEO of the magazine, launching an arguably rocky tenure for Texas Monthly.

In February 2017, Hobby announced that Tim Taliaferro would be taking over the editor in chief position from Brian Sweany, a longtime TM staffer who climbed the ladder from intern in 1996 to taking the editor position following Jake Silverstein's departure for The New York Times Magazine in 2014. About a dozen notable writers left after Sweany's departure, though it's unfair to say it was a result of the masthead shakeup.

Just a few weeks into the Hobby-Taliaferro regime, journalism watchdog Columbia Journalism Review reported that Texas Monthly, a 13-time National Magazine Award winner, was going in a lifestyle direction. Reader reaction — not to mention the response from the journalism world — was swift, forcing the magazine to backpedal.

A year later, the magazine faced another misstep, this one involving Bumble and an alleged pay-for-play on social media. The somewhat salacious story also broke in the Columbia Journalism Review and eventually led to Taliaferro being moved into the newly created role of chief innovation officer. Thus began a year-long search that ended with Dan Goodgame being named editor in January 2019.

It's not breaking news to say it's an uncertain time for journalism, and Texas Monthly has clearly not survived unscathed. But hopefully Duncan Williams' purchase will help move the "national magazine of Texas" into a new era, one with a clear and bold vision.

For the sake of one of the nation's best magazines, we hope so.

Is Texas still full of wildcatters — but for tech and innovation? Some say yes, but with one caveat. Photo by Scott Halleran/Getty Images

Houston's innovation ecosystem channels the wildcatter's spirit — but with one major difference

Tech boom

Historically, Texas has been a land of opportunity, and that might ring true now more than ever since the state's oil boom. As Houston's innovation ecosystem grows and develops, are these entrepreneurs reminiscent of the wildcatter days of the early 1900s? Well, sort of.

"Wildcatting is supposed to be really wild. You're supposed to go out in the field and drill some holes and hope that you find something," says Marc Nathan, vice president of strategy at Egan Nelson in Austin. "Truth is, we're a lot more deliberate than that these days."

Wildcatting and deliberate innovation development were the topics of discussion at a panel in Austin during SXSW. The panel, which was hosted by Rice Business and Texas Monthly, was comprised of three panelists with Houston ties: Gabriella Rowe, CEO of Station Houston, Lawson Gow, CEO and founder of Houston-based The Cannon, and Nathan, who, though based in Austin now, was born and raised in Houston and has done business in town too.

Wildcatting new industries
All three panelists agreed that the entrepreneurial nature of the wildcatters is alive and well within Texas entrepreneurs, just now spread apart multiple industries. Among all of the major Texas cities — or DASH, as Nathan calls it, Dallas, Austin, San Antonio, and Houston — each has its specialty. Austin tends to specialize in consumer-facing technology, Dallas has a hold on B-to-B and transportation, and San Antonio has the military.

For Houston, which is most known for its energy, life sciences, and space technology, has some new territories it's growing in, says Rowe, from cybersecurity to sports technology. And all of these different industries seem to work together, which is encouraging to see for Rowe.

"That's the secret sauce that Houston has in many ways," Rowe says.

This ability to specialize is also what's also special about Houston. Rather than trying to compete with Austin and its consumer technology — Gow gave an example of a startup focusing on a doggy dating app — Houston is doing its own thing.

"What I love about Houston is we're trying to solve big problems," Gow, who is the son of InnovationMap's parent company's CEO, says. "We're not going to be the consumer software capital of the world and, for the most part, we're not going to mess around with doggy dating apps."

Houston's problems to overcome
One of the challenges Houston faces as an innovation ecosystem is access to funds. According to Nathan, putting money into tech is just not Houston investors are used to doing.

"Houstonians invest in the ground, with oil and gas, and on the ground, with real estate, but not in the cloud," Nathan says.

The reason being, Gow says, is investors tend to put money into industries they know, and there's a need for educating these investors in new industries.

"To compare to Austin, more people in Austin have tech startups that have been successful and they turn around and invest in what they know, which is tech startups," Gow says. "There's a generational effect."

Another challenge Houston faces is competition — but not with other Texas cities or the rest of the country. Competition between startups and accelerators for resources has the potential to hinder the city's growth as an ecosystem.

"We are fighting for very scarce resources — and it's not just money," Nathan says. "It's also talent."

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

“This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
“Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
