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share of their father's estate following his death in 2010, when the so-called "death tax" had temporarily been repealed, according to Forbes.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

5 Texas entrepreneurs rank among Forbes' richest self-made women

Must be the money

It's common knowledge Houston Rockets owner Tilman Fertitta and Gulf States Toyota owner Dan Friedkin rank among the wealthiest people in Texas. But did you know that five other entrepreneurs — collectively worth more than $4 billion — stand among the richest self-made women in the country?

Billionaire Thai Lee and millionaires Kendra Scott, Kathleen Hildreth, Whitney Wolfe Herd, and Suzy Batiz appear on Forbes magazine's new list of America's 80 richest self-made women — women who garnered wealth on their own, rather than by inheriting or winning it. And they're in great company, joining the likes of Taylor Swift, Oprah Winfrey, Kylie Jenner, Rihanna, Madonna, Celine Dion, and Beyoncé.

Thai Lee, with an estimated net worth of $3 billion, appears at No. 5 on the Forbes list. She is president and CEO of SHI International Corp., a provider of IT products and services whose more than 17,000 customers include AT&T and Boeing. Revenue at the New Jersey-based company hit $10 billion in 2018; more than 4,000 people work at SHI. Austin is home to SHI's corporate call center and is the hub for its sales division catering to small and midsize businesses.

"In early 2015, we mapped a five-year goal to reach $10 billion in revenue by the end of 2019. Through the hard work of our employees, the strength of our partnerships, and our ability to discern and solve our customers' most pressing IT and business challenges, we reached that goal 12 months early," Lee says in a February release.

At No. 40 on the list, with an estimated net worth of $550 million, is Kendra Scott. She is founder and CEO of Kendra Scott Design Inc. Annual sales at the Austin-based jewelry company hover around $360 million.

In 2017, Boston-based private equity firm Berkshire Partners invested in Scott's company at a valuation of more than $1 billion. Scott started the company in 2002 in the spare bedroom of her home. Today, Scott's business operates 100 jewelry stores, runs massive e-commerce and wholesale units, and employs more than 2,000 people. Last year, the company opened its flagship store on South Congress Avenue.

"There were so many ups and downs through this journey. There were many times that I thought I was going to lose my business. I had no investment capital. I was carrying it all on my shoulders — bootstrapping it, literally," Scott told CNN in 2018.

Kathleen Hildreth, co-founder of aviation-maintenance company M1 Support Services, appears on the list at No. 57, with an estimated net worth of $370 million. She is a West Point graduate and Army veteran who served as a helicopter pilot. Before M1 Support, she worked with defense contractors, including Lockheed Martin and DynCorp. Hildreth calls Aubrey, Texas, in the DFW area, home.

"Anything in the government's [aircraft] inventory, we do work on," Hildreth told Forbes. "You name it." Forbes adds, "The U.S Air Force, U.S. Army, U.S. Navy, and NASA are all clients of M1 Support, which relies entirely on the federal government for business. Most of its revenues come from maintaining military aircraft, including fighter jets such as F15s, F16s, and A10 Thunderbolts."

The fourth Texas entrepreneur on the list is Whitney Wolfe Herd, founder and CEO of Austin-based Bumble Trading Inc., developer of the Bumble dating app for women, and the related Bumble BFF friend-finding app and Bumble Bizz networking app. Herd launched Bumble in 2014 after co-founding dating app Tinder. With an estimated net worth of $290 million, Herd claimed the No. 72 spot on the Forbes list. This is her first year to be ranked.

Bumble counts more than 60 million users in 150 countries. The company's estimated annual revenue totals $175 million, according to Forbes. Russian billionaire Andrey Andreev is the majority owner of Bumble.

"I want to take this sucker around the planet," Herd told Marie Claire last year about the future of Bumble. "Then, who knows, maybe we'll work with [Jeff] Bezos and [Elon] Musk and take it beyond."

At No. 77, with an estimated net worth of $270 million, is Dallas' Suzy Batiz, founder of Poo-Pourri, the before-you-go toilet spray available at major retailers. More than 60 million bottles have sold since the company's founding in 2007; Pou-Pourri is now expanding into shoe and pet odors and a cleaning line.

Asked in 2016 what the riskiest thing was she had ever done professionally, Batiz said not selling her company or taking on investors.

"I had no idea if it was going to work out. It's like being on a game show," she told Forbes. "They hand you the big briefcase and you think, 'You can take this thing of money, or you can gamble and try to stay in the game.' Somehow I knew that my baby, the company, was very similar to a child. It just wasn't ready to be released into the world yet without me."

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
