AMERICA'S WEALTHIEST FAMILIES

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share of their father's estate following his death in 2010, when the so-called "death tax" had temporarily been repealed, according to Forbes.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

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

Casimir

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

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.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.
