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.

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.

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.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”

Aegis Aerospace appoints Houston space leader as new president

moving up

Houston-based Aegis Aerospace's current chief strategy officer, Matt Ondler, will take on the additional role of president on Jan. 1. Ondler will succeed Bill Hollister, who is retiring.

“Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers,” Stephanie Murphy, CEO of Aegis Aerospace, said in a news release.

Hollister guided Aegis Aerospace through expansion and innovation in his three years as president, and will continue to serve in the role of chief technology officer (CTO) for six months and focus on the company's technical and intellectual property frameworks.

"Bill has played an instrumental role in shaping the success and growth of our company, and his contributions leave an indelible mark on both our culture and our achievements," Murphy said in a news release.

Ondler has a background in space hardware development and strategic leadership in government and commercial sectors. Ondler founded subsea robots and software company Houston Mechatronics, Inc., now known as Nauticus Robotics, and also served as president, CTO and CSO during a five-year tenure at Axiom Space. He held various roles in his 25 years at NASA and was also named to the Texas Aerospace Research and Space Economy Consortium Executive Committee last year.

"I am confident that with Matt at the helm as president and Bill supporting us as CTO, we will continue to build on our strong foundation and further elevate our impact in the space industry," Murphy said in a news release. "Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers."

Rice University launches new center to study roots of Alzheimer’s and Parkinson’s

neuro research

Rice University launched its new Amyloid Mechanism and Disease Center last month, which aims to uncover the molecular origins of Alzheimer’s, Parkinson’s and other amyloid-related diseases.

The center will bring together Rice faculty in chemistry, biophysics, cell biology and biochemistry to study how protein aggregates called amyloids form, spread and harm brain cells. It will serve as the neuroscience branch of the Rice Brain Institute, which was also recently established.

The team will work to ultimately increase its understanding of amyloid processes and will collaborate with the Texas Medical Center to turn lab discoveries into real progress for patients. It will hold its launch event on Jan. 21, 2026, and hopes to eventually be a launchpad for future external research funding.

The new hub will be led by Pernilla Wittung-Stafshed, a Rice biophysicist and the Charles W. Duncan Jr.-Welch Chair in Chemistry.

“To make a real difference, we have to go all the way and find a cure,” Wittung-Stafshede said in a news release. “At Rice, with the Amyloid Mechanism and Disease Center as a catalyst, we have the people and ideas to open new doors toward solutions.”

Wittung-Stafshede, who was recruited to Rice through a Cancer Prevention and Research Institute of Texas grant this summer, has led pioneering work on how metal-binding proteins impact neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. Her most recent study, published in Advanced Science, suggests a new way of understanding how amyloids may harm cells and consume the brain’s energy molecule, ATP.

According to Alzheimer’s Disease International, neurodegenerative disease cases could reach around 78 million by 2030 and 139 million by 2050. Wittung-Stafshede’s father died of dementia several years ago.

“This is close to my heart,” Wittung-Stafshede added in the news release. “Neurodegenerative diseases such as dementia, Alzheimer’s and Parkinson’s are on the rise as people live longer, and age is the largest risk factor. It affects everyone.”
