Three Houston startups were granted awards from NASA this month to develop new technologies for the space agency.

The companies are among nearly 300 recipients that received a total agency investment of $44.85 million through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Phase I grant programs, according to NASA.

Each selected company will receive $150,000 and, based on their progress, will be eligible to submit proposals for up to $850,000 in Phase II funding to develop prototypes.

The SBIR program lasts for six months and contracts small businesses. The Houston NASA 2025 SBIR awardees include:

Solidec Inc.

  • Principal investigator: Yang Xia
  • Proposal: Highly reliable and energy-efficient electrosynthesis of high-purity hydrogen peroxide from air and water in a nanobubble facilitated porous solid electrolyte reactor

Rarefied Studios LLC

  • Principal investigator: Kyle Higdon
  • Proposal: Plume impingement module for autonomous proximity operations

The STTR program contracts small businesses in partnership with a research institution and lasts for 13 months. The Houston NASA 2025 STTR awardees include:

Affekta LLC

  • Principal investigator: Hedinn Steingrimsson
  • Proposal: Verifiable success in handling unknown unknowns in space habitat simulations and a cyber-physical system

Solidec and Affekta have ties to Rice University.

Solidec extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions. It was co-founded by Rice professor Haotian Wang and and was an Innovation Fellow at Rice’s Liu Idea Lab for Innovation and Entrepreneurship. It was previouslt selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

Affekta, an AI course, AI assistance and e-learning platform, was a part of Rice's OwlSpark in 2023.

taking off

Houston-based Venus Aerospace successfully completed the first U.S. flight test of its proprietary engine at a demonstration at Spaceport America in New Mexico.

Venus’ next-generation rotating detonation rocket engine (RDRE) is supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA and aims to enable vehicles to travel four to six times the speed of sound from a conventional runway. The recent flight test was the first of an American-developed engine of its kind.

"With this flight test, Venus Aerospace is transforming a decades-old engineering challenge into an operational reality,” Thomas d'Halluin, managing partner at Airbus Ventures, an investor in Venus, said in a news release. “Getting a rotating detonation engine integrated, launch-ready, and validated under real conditions is no small feat. Venus has shown an extraordinary ability to translate deep technical insight into hardware progress, and we're proud to support their bold approach in their attempt to unlock the hypersonic economy and forge the future of propulsion."

Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel. It is designed to be affordable and scalable for defense and commercial systems.

The RDRE is also engineered to work with the company's air-breathing detonation ramjet, the VDR2, which helps enable aircraft to take off from a runway and transition to speeds exceeding Mach 6. Venus plans for full-scale propulsion testing and vehicle integration of this system. Venus’ ultimate goal is to develop a Mach 4 reusable passenger aircraft, known as the Stargazer M4.

"This milestone proves our engine works outside the lab, under real flight conditions," Andrew Duggleby, Venus co-founder and chief technology officer, said in the release. "Rotating detonation has been a long-sought gain in performance. Venus' RDRE solved the last but critical steps to harness the theoretical benefits of pressure gain combustion. We've built an engine that not only runs, but runs reliably and efficiently—and that's what makes it scalable. This is the foundation we need that, combined with a ramjet, completes the system from take-off to sustained hypersonic flight."

The hypersonic market is projected to surpass $12 billion by 2030, according to Venus.

"This is the moment we've been working toward for five years," Sassie Duggleby, CEO and co-founder of Venus Aerospace, added in the release. "We've proven that this technology works—not just in simulations or the lab, but in the air. With this milestone, we're one step closer to making high-speed flight accessible, affordable, and sustainable."

testing 1, 2, 3

Outfitted with a new type of aerospace technology, a rocket engine developed by Houston startup Venus Aerospace for hypersonic flights will undergo testing this summer.

Supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA, Venus Aerospace came up with a new design for nozzles — engine parts that help manage power — for its compact rocket engine. Venus Aerospace says the newly configured nozzles have “exceeded expectations” and will be incorporated into Venus’ upcoming ground-based engine testing.

“We’ve already proven our engine outperforms traditional systems on both efficiency and size,” Venus Aerospace CEO Sassie Duggleby says. “The technology we developed with NASA’s support will now be part of our integrated engine platform — bringing us one step closer to proving that efficient, compact, and affordable hypersonic flight can be scaled.”

The engine at the heart of Venus’ flight platform is called a rotating detonation rocket engine (RDRE). Venus says it’s the first U.S. company to make a scalable, affordable, flight-ready RDRE.

Unlike conventional rocket engines, Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel.

“This is just the beginning of what can be achieved with Venus propulsion technology,” says Andrew Duggleby, chief technology officer at Venus, founded in 2020. “We’ve built a compact high-performance system that unlocks speed, range, and agility across aerospace, defense, and many other applications. And we’re confident in its readiness for flight.”

Last fall, the company unveiled a high-speed engine system that enables takeoff, acceleration, and hypersonic cruising — all powered by a single engine. While most high-speed systems require multiple engines to operate at different speeds, Venus’ innovation does away with the cost, weight and complexity of traditional propulsion technology.

Among other applications, the Venus system supports:

  • Spacecraft landers
  • Low-earth-orbit satellites
  • Vehicles that haul space cargo
  • Hypersonic drones and missiles

Houston health tech startup secures $20M series A, NIH grant amid clinical trials

fresh funding

A clinical-stage Houston health tech company with a novel therapeutic device has raised venture capital funding and secured a grant from the National Institutes of Health.

VenoStent Inc., which is currently in clinical trials with its bioabsorbable perivascular wrap, announced the closing of a $20 million series A round co-led by Good Growth Capital and IAG Capital Partners. The two Charleston, South Carolina-based firms also led VenoStent's 2023 series A round that closed last year at $16 million.

Additionally, the company secured a $3.6 million Small Business Innovation Research (SBIR) Phase II Grant from NIH, which will help fund its multi-center, 200-patient, randomized controlled trial in the United States.

Tim Boire, VenoStent CEO and co-founder, describes 2024 so far as "a momentous year" so far for his company.

"In the span of a few months, we initiated our first clinical sites, enrolled the first patients in our large RCT and closed our Series A with Norwest," Boire says in a news release. "We also received the NIH grant, which enables us to execute our trial with the highest degree of quality and rigor to make it as scientifically robust and impactful to patients as possible.

'Each of these are major company milestones that collectively represent many years of intensive and fruitful R&D and collaboration," he continues. "These recent milestones will propel our company forward to an exciting next phase."

The company's innovation, the SelfWrap, goes around arteriovenous (AV) access sites at the time of AV fistula creation surgery. The device is intended "to accelerate the usability and increase the durability of the fistula sites for chronic kidney disease (CKD) patients requiring hemodialysis," reads the release, "mimicking the arterial environment in veins, which experience a 10x increase in pressure and flow during AV creation and causes the veins to become unusable in dialysis."

Along with the investment, VenoStent announced two new board observers. Norwest General Partner Dr. Zack Scott and Investor Dr. Ehi Akhirome are bringing their expertise to the growing company.

"Norwest's investment is tremendous validation for VenoStent, and we are thrilled to have both Zack and Ehi joining the company's board," VenoStent COO and Co-Founder Geoffrey Lucks adds in the release. "Zack and Ehi have extensive knowledge in our space, and their added value will match the capital and cache of Norwest dollar-for-dollar."

Last year at the same time VenoStent announced its last funding round, the SelfWrap was approved by the U.S. Food and Drug Administration to begin its U.S. Investigational Device Exemption (IDE) study.

"Over half a million people in the U.S. rely on hemodialysis to survive and require an arteriovenous fistula creation surgery in order to receive the treatment. However, the AV fistula procedure has a one-year failure rate of more than 60 percent, which significantly impacts patients' survival rates and quality of life," Scott says in the release. "VenoStent's groundbreaking technology for AV fistula formation, SelfWrap, has the potential to significantly improve these odds. We look forward to working with the VenoStent team as it proves the efficacy of this breakthrough technology in order to improve the lives of hundreds of thousands of CKD patients."

Last summer, Boire told InnovationMap on the Houston Innovators Podcast that he's looking to launch the product in 2026.

NASA doles out $98M in funding to small business innovators, including 6 Texas firms

grants lifting off

Almost 100 small businesses with aerospace technology received the greenlight from NASA on their proposals for grant funding.

NASA approved 112 proposals from 92 small businesses in April. These businesses will receive a slice of the $98 million Phase II funding from the Small Business Innovation Research program. The early-stage $850,000 SBIR grants allow awardees to build on their success from the program's first phase. The firms will have 24 months to execute on their proposals with the fresh funding.

“These Phase II awards support a breadth of technologies that have the potential to be transformational for so many different projects and missions across NASA,” says Jenn Gustetic, director of early stage innovation and partnerships for NASA's Space Technology Mission Directorate, in a news release. “In addition, it’s important that we’re including the innovative potential of all of America’s small businesses and entrepreneurs, so we’re proud that 28% of these awards are to underrepresented small businesses and 31% are to first time SBIR Phase II awardees."

Six of the award recipients are based in Texas. Here are the companies and their proposal technology:

  • Ad Astra Rocket Company, headquartered in Webster: Improved Thermo-Mechanical Design of the VASIMR RF Coupler
  • Lunar Resources Inc., headquartered in Houston: Ultra-Electrical-Efficient Process to Perform Regolith Additive Manufacturing of Complex Structures
  • Lynntech Inc., headquartered in College Station: Miniaturized Reagent Regenerative Ion Analyzer for Elemental Analysis

  • Stone Aerospace Inc., headquartered in Del Valle: Sediment Sequestration for Hot Water Drilling Cryobots
  • Texas Research Institute Austin Inc., headquartered in Austin: Accelerated Creep Test Methodologies for Space Habitat Softgood Structural Materials

The Ad Astra Rocket Company's technology, the Variable Specific Impulse Magnetoplasma Rocket, or VASIMR, is an electrothermal thruster that, once developed using the grant, would allow for faster space travel.

“Our program has the responsibility of supporting ideas and technologies that will have impact on NASA’s work and have strong commercial potential,” says Jason L. Kessler, program executive for NASA's SBIR and Small Business Technology Transfer program, in the release. “We're always excited when we can find technologies that help our agency's missions while also having direct benefits for all."

NASA's SBIR program, which takes no equity, offers up to $1 million to selected business during the first three years. Post Phase II opportunities include up to nearly $3 million in funding. The program is a part of NASA's Space Technology Mission Directorate and managed by NASA’s Ames Research Center in California's Silicon Valley.

Texas voters OK $3 billion for new dementia research institute

state funding

Texas voters on Nov. 4 overwhelmingly approved a ballot measure that provides $3 billion in state funding over a 10-year span for the newly established Dementia Prevention and Research Institute of Texas (DPRIT).

Thanks to the passage of Proposition 14, Texas now boasts the country’s largest state-funded initiative dedicated to dementia research and prevention, according to the Alzheimer’s Association. Up to $300 million in grants will be awarded during the 10-year funding period.

“This is a transformative moment for Texas and for the fight against Alzheimer’s and all other dementia,” said Joanne Pike, president and CEO of the Alzheimer’s Association. “Texans have chosen to invest in hope, innovation, and solutions for the millions of families affected by these devastating diseases. With the passage of Proposition 14, Texas is now poised to lead the nation in dementia research and prevention.”

The association says DPRIT will drive scientific breakthroughs, attract top-notch dementia researchers to Texas, and generate thousands of jobs statewide.

An estimated 460,000 Texans are living with dementia, the association says, and more than one million caregivers support them.

DPRIT is modeled after the Cancer Prevention and Research Institute of Texas (CPRIT). Since 2008, the state agency has awarded nearly $4 billion in grants to research organizations for cancer-related academic research, prevention programs, and product development.

An analysis by the McKinsey Health Institute found that investing in brain health initiatives like DPRIT could boost Texas’ GDP by $260 billion. Much of that GDP bump could benefit the Houston area, which is home to dementia-focused organizations such as UTHealth Houston Neurosciences, Baylor College of Medicine’s Center for Alzheimer’s and Neurodegenerative Diseases, the University of Texas Medical Branch at Galveston’s Collaborative Alzheimer’s Disease and Memory Disorders Program, and the Houston Methodist Research Institute’s John M. O’Quinn Foundation Neurodegenerative Disorders Laboratory.

The Greater Houston Partnership says DPRIT holds the potential “to elevate Texas — particularly Houston — as a hub for brain health research.”

State Sen. Joan Huffman, a Houston Republican, is one of DPRIT’s champions. She sponsored legislation this year to create the institute and ask Texas voters to approve the $3 billion in funding.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said in May. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our health care community.”

Houston Innovation Awards to honor Wade Pinder as 2025 Trailblazer

And the award goes to...

On Nov. 13, we'll gather for the 2025 Houston Innovation Awards to celebrate the best and brightest in Houston innovation right now. And, as is tradition with the annual program, we'll honor one longstanding Houston innovator with the Trailblazer Award.

The award was established to recognize an individual who has left a profound impact on Houston's business and innovation ecosystem and is dedicated to continuing to support Houston and its entrepreneurs. The recipient is selected by our esteemed panel of judges from a pool of internal and external recommendations.

The 2025 Trailblazer Award recipient is Wade Pinder of Product Houston. A familiar face to those active in Houston's innovation sector, Pinder identifies as an "Ecosystem Wayseeker" and is the founder of Product Houston.

Pinder, a former product manager at Blinds.com, arrived in Houston in 2008 and has been deeply engaged in Houston’s startup and innovation scene since 2012. Over the years, he has supported hundreds of founders, product leaders, and community builders across the Houston area.

In 2023, he was honored as Mentor of the Year in the Houston Innovation Awards. Today, he fosters collaboration, clarity, and connection through his work at Product Houston, and he helps innovators find their place in the local sector via his monthly "Houston Ecosystem Mapping" sessions.

Read below for Pinder's insightful takes on the Houston innovation scene and what it means to blaze a new trail. Then, join us as we celebrate Pinder and all of our nominees and winners at the 2025 Houston Innovation Awards on Nov. 13 at Greentown Labs. Tickets are available now.

InnovationMap: Describe the growth of the Houston innovation ecosystem from your arrival in 2008 to now.

Wade Pinder: When I first arrived in Houston in 2008, the innovation ecosystem was more fragmented than it is today. Connecting with other innovators often meant attending a lot of hit-or-miss events. Over the years, it’s been incredible to see the network take shape and grow into a true community. I’ve had the privilege of being involved with several coworking spaces and accelerator programs along the way, and it’s been especially exciting to see Station Houston evolve into what is now the Ion District. What makes the Ion unique is how it blends openness and opportunity… ideas spill into and out of the space, and anyone can walk in, participate in programming, and find themselves in proximity to people who might help them take the next steps.

Additionally, the expansion of spaces like Texas Medical Center Innovation, Helix Park, The Cannon, and many others, have broadened Houston’s innovation landscape in powerful ways.

Today, when someone new moves to Houston and wants to plug into the startup and innovation scene, it’s much easier for them to find their way than when I moved here in 2008. I think that’s something Houston can really be proud of.

IM: As someone who engages with the broader Houston innovation community on a regular basis, what are the shared characteristics and traits that you see among its members?

WP: One of the things that makes Houston’s innovation community unique is how deeply it’s rooted in industry. So many of the innovators I meet come from within Houston’s major sectors, and they’ve seen firsthand where opportunities lie, which gives their innovation a certain practicality. They’re developing solutions that solve real, often complex, business and industry problems, not chasing trends or trying to create the next flashy consumer app.

What I admire most is that this community is growing in its understanding of the value of collaboration. They work with the systems and expertise that already exist, and find better ways to make them work together. Another shared trait I see across Houston’s innovators is a deep sense of curiosity and a drive to question the status quo while looking for better ways to build, improve, and solve.

IM: You’ve said, "Houston has Houston problems, and Houston needs Houston solutions." How do you see this taking shape in the innovation sector right now?

WP: When I first started getting connected to Houston’s startup and innovation scene in 2012, I noticed folks had a tendency to look at other cities and ask, "How can we do what they did?" Back then, we saw phrases like "Silicon Bayou" pop up, and while that enthusiasm was hopeful, it often discounted the things that make Houston unique. Over time, I’ve come to believe that the better question is: "What are we already great at, and how can we innovate from there?" The flip side of that question is to reflect on the things that hold us back as an ecosystem… identifying the friction points and finding practical ways to smooth them out.

From my time wandering around our ecosystem, I’ve come to understand Houston is great at infrastructure at scale, solving life-and-death challenges in the global spotlight, and "boldly going where no one’s gone before." These three things, in my opinion, capture the essence of Houston does best: We do hard things here.

What excites me today is that we’re applying innovation to those core strengths in ways that feel authentically Houston. One area I’m especially excited about is the emergence of the “New Space Economy,” captured beautifully in Wogbe Ofori’s thought piece “The Astropreneur’s Startup Journey Map.” It's a great example of how the next wave of space-related innovation might connect to Houston’s long-standing strengths in manufacturing, logistics, and problem-solving at scale.

Another challenge Houston faces is what I call a "proximity problem." Even when events are only a few miles apart, traffic can make it difficult for people to stay connected across the city. That’s why I’m so encouraged by the rise of what I think of as "intent-based gatherings" around the city: events designed with purpose, where people know they’ll find real connection and value once they arrive.

IM: Finally, what does being a "Trailblazer" mean to you?
WP: To me, trailblazing in the Houston innovation ecosystem means being willing to wander through the many different corners of the community and look for value in places we often overlook. It’s about showing up at events, community meetings, and pitch competitions — not just to participate, but to notice how each of these "nodes" in the ecosystem connects and adds value to the others.

Sometimes the trailblazer only walks a trail once: as they are discovering it. If you can help others see a newfound trail’s purpose and potential, it becomes a path others can follow more easily in the future. That’s the real work of a trailblazer: mapping connections, framing their value, and helping people recognize how those pathways strengthen the ecosystem as a whole.

In a broader sense, trailblazing is about seeing things not just as they are, but as they could be. Then taking the steps, however small, that make that vision real.
