Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from adtech to aerospace — recently making headlines in Houston innovation.

Mark Walker, CEO, co-founder and chairman of Direct Digital Holdings

Houston-based Direct Digital Holdings, an adtech platform, is celebrating one year after its IPO. Co-Founder Mark Walker shares on the Houston Innovators Platform how he took this experience in tech, advertising, and media to create his company's platform.

He also shared the story of how Direct Digital went public. Walker says the decision to IPO made the most sense for his company — though it wasn't an easy process. Direct Digital is only the ninth company founded by a Black entrepreneur to go public on a US stock exchange.

"If you think the process is hard — it actually is," Walker says on the journey to IPO. "We were a privately held company, and we knew we had a good growth trajectory and we looked a couple different options. We decided to go public in a very traditional way." Read more.

Intuitive Machines, a space tech company based in Southeast Houston, announced that it has completed the transaction to merge with Inflection Point Acquisition Corp., a special purpose acquisition company traded on Nasdaq.

“We are excited to begin this new chapter as a publicly traded company,” says Steve Altemus, co-founder, president, and CEO of Intuitive Machines, in a news release. “Intuitive Machines is in a leading position to replace footprints with a foothold in the development of lunar space. With our launch into the public sphere through Inflection Point, we have reached new heights financially and opened the doors for even greater exploration and innovation for the progress of humanity.”

The transaction, which was originally announced in September, was approved by Inflection Point’s shareholders in a general meeting on February 8. As a result of the deal, the company will receive around $55 million of committed capital from an affiliate of its sponsor and company founders, the release states. Read more.

Umbrage, founded in 2019, is proving once again that Space City is a software hub. Earlier this month, Founder Will Womble announced that Umbrage has been acquired by Bain & Company.

Umbrage creates custom software for companies by partnering with an internal technology team that makes the products. It’s a “teach a man to fish” method that has brought the company great success in creating software such as Shell’s TapUp app.

Bain & Company works with clients in 64 cities across 39 countries, meaning the global consultancy is positioned to bring Umbrage worldwide.

"Alongside Bain, we can deliver enhanced end-to-end solutions that will position our clients for success and to adapt during waves of disruptive emerging technologies," says CEO Womble in the release. Read more.

A Houston software company is celebrating an exit this month.

Umbrage, founded in 2019, is proving once again that Space City is a software hub. Earlier this month, Founder Will Womble announced that Umbrage has been acquired by Bain & Company.

Umbrage creates custom software for companies by partnering with an internal technology team that makes the products. It’s a “teach a man to fish” method that has brought the company great success in creating software such as Shell’s TapUp app.

Bain & Company works with clients in 64 cities across 39 countries, meaning the global consultancy is positioned to bring Umbrage worldwide.

"Alongside Bain, we can deliver enhanced end-to-end solutions that will position our clients for success and to adapt during waves of disruptive emerging technologies," says CEO Womble in the release.

Bain’s Vector program has advised more than 6,700 digital projects around the world and across industries. It works by creating joint teams featuring Bain’s consulting staff, allowing companies to reach their digital goals themselves, but with a little help, not unlike Umbrage’s own methods. Acquiring Umbrage gives Bain a boost in its ability to help clients on a larger scale.

"Bain's commitment to delivering results with clients requires expanding and enhancing its ability to innovate and industrialize digital solutions," says Arpan Sheth, global leader of Vector, Bain's digital delivery platform. "Joining forces with Umbrage will allow us to develop a best-in-class, craft-centric digital product and venture building studio that will enable our clients to not only develop successful digital strategies, but to also execute on these strategies through world-class software capabilities. Umbrage further enhances Bain's Next solution to support our clients in their business building missions.”

Once the deal is completed, Umbrage will operate independently, but as a branded service line that’s part of Bain Innovation & Design. But existing clients needn’t worry. Umbrage will continue to assist them, including clients in financial services, energy, natural resources, and other industries.

In 2021, Umbrage raised a $2 million round led by Rice Investment Group. Womble previously joined the Houston Innovators Podcast to share how Houston has played a role in the company's growth.

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from energy to health care — recently making headlines in Houston innovation.

Will Womble, CEO of Umbrage

Startup founder on how Houston has evolved as a software hub — and why there's no better place to be

Will Womble describes his company, Umbrage, as fiercely loyal to Houston. The business, which publicly launched earlier this year, supports companies large and small with their software design, development, and more. Womble says he saw a void in Houston for this type of company, and he's attempting to fill it.

"What makes us different is speed to market — we're all onshore. We're all Houston-based, with the exception of five of our 40 employees," Womble says. "Houston was our focus and mission."

Womble has seen Houston evolve as an innovation ecosystem over the years, and now the game has changed. Click here to read more.

Startup founder on how Houston has evolved as a software hub — and why there's no better place to be

HOUSTON INNOVATORS PODCAST EPISODE 94

It's no understatement to say that Will Womble is incredibly proud to be a Houstonian. The former actor and lawyer first got involved in the startup world by way of Austin — but he always advocated for his hometown.

"Houston is always third in line when it comes to the 'cool kid' in Texas," Womble says on this week's episode of the Houston Innovators Podcast. "But when you look at what's here, there's not a city outside of New York City with as many Fortune 500 companies. ... I just wanted to go prove that Houston has some really talented software developers just clamoring for the opportunity to show the talent."

An early hire at Chaotic Moon — later acquired by Accenture, Womble co-founded Austin-based Hypergiant before founding his latest venture, Umbrage. The company, which publicly launched earlier this year, supports companies large and small with their software design, development, and more.

The company, which Womble describes as a service-focused, crafts-based digital studio, works with its clients to design, develop, and deliver enterprise software that's cutting edge and scalable. The other thing? Umbrage is fiercely loyal to Houston. Womble says he saw a void in Houston for this type of company, and he's attempting to fill it.

"What makes us different is speed to market — we're all onshore. We're all Houston-based, with the exception of five of our 40 employees," Womble says. "Houston was our focus and mission."

Womble has seen Houston evolve as an innovation ecosystem over the years, and now the game has changed — especially when it comes to hiring, which has gotten very competitive.

"You see all of these great companies that aren't just bootstrapping but raising significant venture funding," Womble says. "It's awesome, but it's also making the landscape from the talent perspective very competitive. It was hard enough for a lot of industrial enterprise to attract talent before all of these startups were infused with capital to build their own teams."

These types of challenges aren't a deterrant for Womble — it's exciting for him.

"It's a really awesome time to be called a Houstonian," he says.

Womble shares more on his circuitous career and how he's seen the Houston innovation ecosystem evolve on the podcast. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Texas cybersecurity co. expands unique train-to-hire model to Houston

job search

It’s increasingly more difficult to ensure the confidentiality, integrity, and availability of proprietary data and information in the ever-changing, ever-evolving digital world.

Cyberattacks, including malware, phishing, and ransomware, are becoming increasingly common and sophisticated, posing a consistent threat to a company’s sustainability and bottom line.

To combat that trend, Nukudo, a San Antonio-based cybersecurity workforce development company, is expanding its initiative to bridge the global cybersecurity talent gap through immersive training and job placement to Houston.

“We saw that there was a need in the market because there's a shortage of skilled manpower within the cybersecurity industry and other digital domains,” says Dean Gefen, CEO of NukuDo. “So, our initial goal was to take a large pool of people and then make them to be fully operational in cybersecurity in the shortest amount of time.”

The company refers to the plan as the “training-to-employment model,” which focuses on providing structured training to select individuals who then acquire the skills and knowledge necessary to secure and maintain fruitful careers.

The company identifies potential associates through its proprietary aptitude test, which recognizes individuals who possess the innate technical acumen and potential for success in various cybersecurity roles, regardless of their level of education.

“We take in people from all walks of life, meaning the program is purely based on the associate’s potential,” Gefen says. “We have people who were previously aircraft engineers, teachers, graphic designers, lawyers, insurance agents and so forth.”

Once selected, associates are trained by cybersecurity experts while gaining hands-on experience through scenario-based learning, enabling them to be deployed immediately as fully operational cybersecurity professionals.

The program training lasts just six months—all paid—followed by three years of guaranteed employment with NukuDo.

While in training, associates are paid $ 4,000 per month; then, they’re compensated by nearly double that amount over the next three years, ultimately pushing their salaries to well into the six figures after completing the entire commitment.

In addition to fostering a diverse talent pipeline in the cybersecurity field, NukuDo is creating a comprehensive solution to address the growing shortage of technical talent in the global workforce.

And arming people with new marketable skills has a litany of benefits, both professional and personal, Gefen says.

“Sometimes, we have associates who go on to make five times their previous salary,” says Gefen. “Add to that fact that we had someone that had a very difficult life beforehand and we were able to put him on a different path. That really hits home for us that we are making a difference.

Nulkudo currently has partnerships with companies such as Accenture Singapore and Singapore Airlines. Gefen says he and his team plans to have a new class of associates begin training every month by next year and take the model to the Texas Triangle (Houston, Austin and Dallas)—then possibly nationwide.

“The great thing about our program is that we train people above the level of possible threat of replacement by artificial intelligence,” Gefen says. “But what we are also doing, and this is due to requirements that we have received from clients that are already hiring our cyber professionals, is that we are now starting to deliver AI engineers and data scientists in other domains.”

“That means that we have added more programs to our cybersecurity program. So, we're also training people in data science and machine learning,” he continues.

All interested candidates for the program should be aware that a college degree is not required. NukuDo is genuinely interested in talented individuals, regardless of their background.

“The minimum that we are asking for is high school graduates,” Gefen says. “They don't need to have a college degree; they just need to have aptitude. And, of course, they need to be hungry to make this change.”

2 Houston universities declared among world’s best in 2026 rankings

Declaring the Best

Two Houston universities are in a class of their own, earning top spots on a new global ranking of the world's best universities.

Rice University and University of Houston are among the top 1,200 schools included in the QS World University Rankings 2026. Ten more schools across Texas make the list.

QS (Quacquarelli Symonds), a London-based provider of higher education data and analytics, compiles the prestigious list each year; the 2026 edition includes more than 1,500 universities from around the world. Factors used to rank the schools include academic reputation; employer reputation; faculty-student ratio; faculty research; and international research, students, and faculty.

In Texas, University of Texas at Austin lands at No. 1 in the state, No. 20 in the U.S., and No. 68 globally.

Houston's Rice University is close behind as Texas' No. 2 school. It ranks 29th in the U.S. and No. 119 in the world. Unlike UT, which fell two spots globally this year (from No. 66 to 68), Rice climbed up the charts, moving from 141st last year to No. 119.

University of Houston impresses as Texas' 4th highest-ranked school. It lands at No. 80 in the U.S. and No. 556 globally, also climbing about 100 spots up the chart.

Rice and UH are on a roll in regional, national, and international rankings this year.

Rice earned top-15 national rankings by both Niche.com and Forbes last fall. Rice claimed No. 1 and UH ranked No. 8 in Texas in U.S. News & World Report's 2025 rankings. Rice also topped WalletHub's 2025 list of the best colleges and universities in Texas for 2025.

More recently, in April, both UH and Rice made U.S. News' 2025 list of top grad schools.

In all, 192 U.S. universities made the 2026 QS World University Rankings — the most of any country. Topping the global list is the Massachusetts Institute of Technology (MIT).

“The results show that while U.S. higher education remains the global leader, its dominance is increasingly challenged by fast-rising emerging systems,” says the QS World University Rankings report. “A decade ago, 32 American universities [were] featured in the world’s top 100; today, that number has dropped to 26, and only 11 of these institutions have improved their position this year."

The 12 Texas universities that appear in the QS World University Rankings 2026 list are:

  • University of Texas at Austin, No. 20 in the U.S. and No. 68 in the world (down from No. 66 last year).
  • Rice University, No. 29 in the U.S. and No. 119 in the world (up from No. 141 last year).
  • Texas A&M University, No. 32 in the U.S. and No. 144 in the world (up from No. 154 last year).
  • University of Houston, No. 80 in the U.S. and No. 556 in the world (up from 651-660 last year).
  • University of Texas at Dallas, No. 85 in the U.S. and No. 597 in the world (down from 596 last year).
  • Texas Tech University, No. 104 in the U.S. and No. 731-740 in the world (unchanged from last year).
  • University of North Texas, No. 123 in the U.S. and No. 901-950 in the world (up from 1,001-1,200 last year)
  • Baylor University, tied for No. 136 in the U.S. and at No. 1,001-1,200 in the world (unchanged from last year).
  • Southern Methodist University, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas Arlington, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at San Antonio, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at El Paso, No. 172 in the U.S. and at 1,201-1,400 in the world (down from 1,001-1,200 last year).

Houston students develop new device to prepare astronauts for outer space

space race

Rice University students from the George R. Brown School of Engineering and Computing designed a space exercise harness that is comfortable, responsive, and adaptable and has the potential to assist with complex and demanding spacewalks.

A group of students—Emily Yao, Nikhil Ashri, Jose Noriega, Ben Bridges and graduate student Jack Kalicak—mentored by assistant professor of mechanical engineering Vanessa Sanchez, modernized harnesses that astronauts use to perform rigorous exercises. The harnesses are particularly important in preparing astronauts for a reduced-gravity space environment, where human muscles and bones atrophy faster than they do on Earth. However, traditional versions of the harnesses had many limitations that included chafing and bruising.

The new harnesses include sensors for astronauts to customize their workouts by using real-time data and feedback. An additional two sensors measure astronauts’ comfort and exercise performance based on temperature and humidity changes during exercise and load distribution at common pressure points.

“Our student-led team addressed this issue by adding pneumatic padding that offers a customized fit, distributes pressure over a large surface area to reduce discomfort or injuries and also seamlessly adapts to load shifts — all of which together improved astronauts’ performance,” Sanchez said in a news release. “It was very fulfilling to watch these young engineers work together to find innovative and tangible solutions to real-world problems … This innovative adjustable exercise harness transforms how astronauts exercise in space and will significantly improve their health and safety during spaceflights.”

The project was developed in response to a challenge posted by the HumanWorks Lab and Life Science Labs at NASA and NASA Johnson Space Center for the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge, where teams worked to solve problems for industry leaders.

Rice’s adaptive harness won the Best Challenge Response Award. It was funded by the National Science Foundation and Rice’s Office of Undergraduate Research and Inquiry.

“This challenge gave us the freedom to innovate and explore possibilities beyond the current harness technology,” Yao added in the release. “I’m especially proud of how our team worked together to build a working prototype that not only has real-world impact but also provides a foundation that NASA and space companies can build and iterate upon.”
