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billion share of their father's estate following his death in 2010, when the so-called "death tax" had temporarily been repealed, according to Forbes.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.

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."

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
