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.

Houston investor on SaaS investing and cracking product-market fit

Houston innovators podcast episode 230

Aziz Gilani's career in tech dates back to when he'd ride his bike from Clear Lake High School to a local tech organization that was digitizing manuals from mission control. After years working on every side of the equation of software technology, he's in the driver's seat at a local venture capital firm deploying funding into innovative software businesses.

As managing director at Mercury, the firm he's been at since 2008, Gilani looks for promising startups within the software-as-a-service space — everything from cloud computing and data science and beyond.

"Once a year at Mercury, we sit down with our partners and talk about the next investment cycle and the focuses we have for what makes companies stand out," Gilani says on the Houston Innovators Podcast. "The current software investment cycle is very focused on companies that have truly achieved product-market fit and are showing large customer adoption."



An example of this type of company is Houston-based RepeatMD, which raised a $50 million series A round last November. Mercury's Fund V, which closed at an oversubscribed $160 million, contributed to RepeatMD's round.

"While looking at that investment, it really made me re-calibrate a lot of my thoughts in terms what product-market fit meant," Gilani says. "At RepeatMD, we had customers that were so eager for the service that they were literally buying into products while we were still making them."

Gilani says he's focused on finding more of these high-growth companies to add to Mercury's portfolio amidst what, admittedly, has been a tough time for venture capital. But 2024 has been looking better for those fundraising.

"We've some potential for improvement," Gilani says. "But overall, the environment is constrained, interest rates haven't budged, and we've seen some potential for IPO activity."

Gilani shares more insight into his investment thesis, what areas of tech he's been focused on recently, and how Houston has developed as an ecosystem on the podcast.

Houston energy startup closes $17M series A to fund Texas geothermal facility

money moves

A Houston geothermal startup has announced the close of its series A round of funding.

Houston-based Sage Geosystems announced the first close of $17 million round led by Chesapeake Energy Corp. The proceeds aim to fund its first commercial geopressured geothermal system facility, which will be built in Texas in Q4 of 2024. According to the company, the facility will be the first of its kind.

The venture is joined by technology investor Arch Meredith, Helium-3 Ventures and will include support from existing investors Virya, LLC, Nabors Industries Ltd., and Ignis Energy Inc.

“The first close of our Series A funding and our commercial facility are significant milestones in our mission to make geopressured geothermal system technologies a reality,” Cindy Taff, CEO of Sage Geosystems, says in a news release. “The success of our GGS technologies is not only critical to Sage Geosystems becoming post-revenue, but it is an essential step in accelerating the development of this proprietary geothermal baseload approach.

"This progress would not be possible without the ongoing support from our existing investors, and we look forward to continuing this work with our new investors," she continues.

The 3-megawatt commercial facility will be called EarthStore and will use Sage’s technology that harvests energy from pressurized water from underground. The facility will be able to store energy — for short and long periods of time — and can be paired with intermittent renewable energy sources like wind and solar. It will also be able to provide baseload, dispatchable power, and inertia to the electric grid.

In 2023, Sage Geosystems debuted the EarthStore system in a full-scale commercial pilot project in Texas. The pilot produced 200 kilowatt for more than 18 hours, 1 megawatt for 30 minutes, and generated electricity with Pelton turbines. The system had a water loss of less than 2 percent and a round-trip efficiency (RTE) of 70-75.

Rice University medical device spinout secures nearly $19M series A

fresh funding

A health tech startup based out of a newly formed accelerator program at Rice University has raised venture funding.

Motif Neurotech closed its series A round with an oversubscribed $18.75 million. The company, which develops minimally invasive bioelectronics for mental health treatment, was formed out of the Rice Biotech Launch Pad that launched last fall.

The round was led by Arboretum Ventures, with participation from new investors KdT Ventures, Satori Neuro, Dolby Family Ventures, re.Mind Capital and existing investors Divergent Capital, TMC Venture Fund, PsyMed Ventures, Empath Ventures and Capital Factory, according to a news release from Rice.

“Minimally invasive bioelectronics are the future of mental health treatment,” Jacob Robinson, CEO and founder of Motif Neurotech, says in the release. “Thirty percent of patients with depression don’t respond to two or more medications, and there is a significant need for additional treatment options that are effective and easily accessible."

The fresh funding will go toward developing the inaugural product, the DOT microstimulator, a wireless, battery-free device that can provide at-home therapy for treatment-resistant depression, or TRD, a major depressive disorder.

“This is a pivotal moment for the company as it closes its Series A in addition to the recent successful completion of the proof-of-concept first-in-human implant of the DOT stimulator device," Tom Shehab, managing partner of Arboretum Ventures, says in the release. "We believe Motif’s device will greatly improve the quality of life for patients who have been diagnosed with difficult to treat mental health disorders, including TRD."

Shehab, along with Amy Kruse, chief investment officer of Satori Neuro, will reportedly join Motif Neurotech's board of directors alongside Anthony Arnold, president and CEO of Sensydia Corporation, and Jacob Robinson, professor of electrical and computer engineering and bioengineering at Rice.

The Rice Biotech Launch Pad was established to take biotech innovations from concept to clinical trials in five years or less. It occupies 15,000 square feet of space on campus and is funded through federal grants and donations.

This Houston medical device innovator plans to lead a 'paradigm shift' in vascular surgery

HOUSTON INNOVATORS PODCAST EPISODE 199

Commercializing a health tech innovation is a long game — fraught with regulatory obstacles, cyclical rounds of funding, and continuous improvement — all fueled by the desire to enhance treatment and save lives.

That's Tim Boire's plan. And it's a thorough one at that. On this week's episode of the Houston Innovators Podcast, Boire — president and CEO of VenoStent, a medical device startup that’s designing a unique material for hemodialysis patients — shares his roadmap for his company.

"We believe we can be pioneers of a paradigm shift in vascular surgery — to not just treat problems after they've already occurred, but actually prevent them from occurring in the first place," he says in the episode.

VenoStent's most recent hurdle cleared is closing a $16 million series A round of venture funding. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round. The TMC Venture Fund also contributed.

Now, VenoStent is headed for a 200-patient trial in the United States, with an ultimate goal of product launch in 2026. The company's unique medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

Boire had the idea for VenoStend when he was completing his PhD at Vanderbilt University. He completed the program, and then joined the HealthWildcatters accelerator in 2017 in Dallas. After that, Boire and his co-founder, Geoff Lucks, decided to take the leap and move to Houston to join JLABS at TMC. The rest, as they say, is history.

“Houston’s been a great place to hire,” Boire says. “We've been I think very fortunate to find our employees who are stellar, true believers in the technology — amazing engineers, and amazing people.”

And, of course, Boire has a plan to continue this hiring success. He says the goal is to grow to a team of 16 by the end of the year. Marketing and sales roles will likely be filled in 2025 ahead of product launch.

“When we think about what our mission is at VenoStent, it’s to ultimately improve patient care — and we are very passionate about this specific problem that patients experience and go through,” Boire says.

“That's what drives everything we're doing as a company to improve quality and length of life for patients who have chronic kidney disease that progresses to a point where they need dialysis to sustain life," he continues. "We believe that we can become the standard care for vascular surgery starting with hemodialysis access."

As VenoStent's trials and growth goes according to plan, Boire says this product can be used for other implications.

Boire shares more on his grand plan, plus how he weathered the storm that is fundraising at a time where so much venture capital activity has slowed. Listen to the interview here — or wherever you stream your podcasts — and subscribe for weekly episodes.

UH scores $18M NIH grant for chronic disease research

research funding

The University of Houston has received a coveted $18.8 million grant from the National Institutes of Health to launch a program to address the root causes of chronic disease.

Only 22 institutions nationwide receive this NIH award, and the 5-year process aligns with the newly established UH Health’s mission to expand healthcare innovations in Texas and beyond. The initiative will be housed in the UH Population Health department.

"This generous funding allows us to directly confront the root causes of chronic illness that place a heavy burden on so many families," Dr. Jonathan McCullers, vice president for health affairs at UH, said in a news release. "With the recent launch of UH Health, we have an unprecedented opportunity to translate scientific discovery into healthier outcomes for our communities by bringing together experts from across the university to improve health where it matters most.”

Through the program, UH researchers from different areas of expertise will work together to address the challenges of chronic illness by looking at biological, social and behavioral factors.

According to the university, chronic diseases like heart disease, diabetes, strokes and others are the leading cause of illness, disability and death in the U.S. They account for 90 percent of the nation’s $5.3 trillion in annual healthcare spending.

Bettina Beech, chief of population health and translational science at UH, serves as principal investigator for the program.

“Chronic disease management largely happens during the 8,700 hours each year that people are not visiting their healthcare provider,” Beech added in the news release. “While healthcare is indispensable, it only accounts for 20 percent of how health is created — genetics accounts for another 10 percent, and the other 70 percent is determined by behavior, social conditions and environment.”

With the funds from the grant, UH will also be able to expand research infrastructure, add to community partnerships, support complementary research, and invest in early-career investigators, according to the news release. UH also aims to develop solutions that could help ease the economic burden of chronic disease.

Report: Where Texas ranks among best and worst states to live in 2026

Texas Talk

After earning its worst-ever ranking last year, Texas has improved slightly on an evaluation of the best states to live, but it's still at the bottom of the pack.

Each year, WalletHub's analysts compare all 50 states using 51 livability metrics to measure their affordability, economy, education and health, quality of life, and safety. Factors that were weighed include the cost of living, homeownership rates, population and income growth rates, wealth gaps, public school system quality, road quality, crime rates, and many others.

The Lone Star State landed at No. 36 in 2026, making it the 15th worth state to live right now. That's on par with its 2024 ranking, and it's a two-spot improvement over its 2025 performance.

While Texas residents can brag about living in a state with the No. 1 highest number of restaurants per capita and the 7th best quality of life in the country, that's about it. Texas earned middling-to-poor scores among the four remaining livability rankings: safety (No. 33), affordability (No. 35), economy (No. 37), and education and health (No. 40).

Here's how Texas fared in other nationwide rankings in the study:

  • No. 27 – Income Growth
  • No. 30 – Housing Costs
  • No. 39 – Percentage of Population in Poverty
  • No. 42 – Percentage of Adults in Fair or Poor Health
  • No. 46 – Homeownership Rate
  • No. 49 – Percentage of Population Aged 25 and Older with a High School Diploma or Higher
  • No. 48 – Average Weekly Work Hours
  • No. 50 – Percentage of Insured Population

Texas has a lot of work to do to improve its livability for all of its residents, but especially for women, according to several other 2026 WalletHub studies. Texas is the fourth-worst state for women, the ninth-worst state for working mothers, and the seventh-worst place to have a baby based on limited access to maternal and pediatric healthcare.

At the very bottom of the report is New Mexico, ranking 50th overall, with Louisiana (No. 49), Mississippi (No. 48), Alaska (No. 47), and Arkansas (No. 46) rounding out the bottom five.

After holding on as the No. 1 best state to live for a few years in a row, Massachusetts now ranks No. 4 and was overtaken by Idaho (No. 1), New Jersey (No. 2), and Wisconsin (No. 3). New Hampshire rounds out the top five best states to live.

WalletHub's top 10 best states to live in 2026 are:

  • No. 1 – Idaho
  • No. 2 – New Jersey
  • No. 3 – Wisconsin
  • No. 4 – Massachusetts
  • No. 5 – New Hampshire
  • No. 6 – Wyoming
  • No. 7 – Utah
  • No. 8 – Minnesota
  • No. 9 – Pennsylvania
  • No. 10 – Florida
