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 energy leaders back battery startup's $15.8M series A

Money moves

A California startup that's revolutionizing polymer cathode battery technology has announced its series A round of funding with support from Houston-based energy transition leaders.

LiNova Energy Inc. closed a $15.8 million series A round led by Catalus Capital. Saft, a subsidiary of TotalEnergies, which has its US HQ in Houston, and Houston-based Chevron Technology Ventures, also participated in the round with a coalition of other investors.

LiNova will use the funds with its polymer cathode battery to advance the energy storage landscape, according to the company. The company uses a high-energy polymer battery technology that is designed to allow material replacement of the traditional cathode that is made up of cobalt, nickel, and other materials.

The joint development agreement with Saft will have them collaborate to develop the battery technology for commercialization in Saft's key markets.

“We are proud to collaborate with LiNova in scaling up its technology, leveraging the extensive experience of Saft's research teams, our newest prototype lines, and our industrial expertise in battery cell production," Cedric Duclos, CEO of Saft, says in a news release.

CTV recently announced its $500 million Future Energy Fund III, which aims to lead on emerging mobility, energy decentralization, industrial decarbonization, and the growing circular economy. Chevron has promised to spend $10 billion on lower carbon energy investments and projects by 2028.

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.

Intuitive Machines lands $600M satellite deal, NASA ‘spacecraft bus’ contract

space deals

Houston-based space infrastructure company Intuitive Machines has scored two astronomical deals.

The deals add to the company’s soaring success. As of June 30, Intuitive Machines had a record-high $1.8 billion backlog of orders, a $1.5 billion increase from the end of last year. The current backlog includes orders for more than 80 spacecraft.

The company, which went public in 2023, expects this year’s revenue to total $900 million to $1 billion. In the first half of 2026, Intuitive Machines generated nearly $393 million in revenue.

Intuitive Machines estimates its total available market is valued at more than $150 billion.

$600 million-plus deal represents ‘important milestone’

On Monday, Intuitive Machines said it picked up a $600 million-plus deal to develop three commercial satellites for an undisclosed customer over the course of about two years.

Intuitive Machines says it will design, manufacture, set up and support several spacecraft “for a critical communications infrastructure mission.”

Steve Altemus, the company’s CEO, says the deal represents “an important milestone for Intuitive Machines and reflects the confidence our customers place in our ability to deliver high-performance spacecraft for a broad range of mission needs.”

Company nails down NASA deal for ‘spacecraft bus’

A day after announcing the $600 million-plus deal, Intuitive Machines said it secured a new contract with NASA.

Intuitive Machines says NASA’s Jet Propulsion Laboratory in Southern California will use the company’s IM 300 “spacecraft bus” for an EAGLE-VSWIR Earth observation mission. The mission is scheduled to launch in 2028.

Aside from supplying the IM 300 bus, Intuitive Machines will carry out mission support services.

The low-Earth-orbit mission will be equipped with Intuitive Machines’ hyperspectral visible to shortwave infrared (VSWIR) instrument. This technology sees colors and details that aren’t visible to the human eye.

The instrument is “designed to perform surface biology and geology observations from Earth orbit while demonstrating technologies that could support future lunar and Mars exploration missions,” Intuitive Machines says.

Intuitive Machines builds mission-critical spacecraft, systems, and infrastructure for business and government customers. To date, the company has produced more than 300 spacecraft, delivered over 575 pounds of payload to the moon and launched about 100 satellites.

9 Houston-based companies make Fortune Global 500 list in 2026

Worldwide Rankings

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.

Fast-growing Houston real estate startup surges to No. 7 on Inc. 5000

growth report

Houston-based Epique Realty has ridden the AI wave to rank among the Inc. 5000’s 10 fastest-growing private companies.

With three-year revenue growth of 23,210 percent, the AI-powered real estate brokerage appears at No. 7 on this year’s Inc. 5000 list. The 2026 list ranks private companies based on percentage revenue growth from 2022 to 2025.

Epique, founded in 2021, also ranks as the No. 1 fastest-growing company in Houston, No. 1 fastest-growing real estate company in the U.S., and No. 2 fastest-growing company in Texas.

Epique’s annual revenue surpasses $91 million

Between 2022 and 2025, the company’s annual revenue skyrocketed from $391,654 to more than $91.2 million. In 2025, the brokerage closed more than 23,000 deals and surpassed $7 billion in total sales, elevating Epique to the country’s 14th-largest real estate brokerage as measured by volume.

Epique’s network has more than 4,000 agents.

“To debut in the top 10 of the Inc. 5000 is absolute proof that when you relentlessly put agents first, exponential growth takes care of itself,” co-founder and CEO Joshua Miller said in a news release.

“We didn’t achieve this by following the industry playbook; we achieved this by burning it,” Miller added. “By fully funding our agents’ success through free health care, proprietary AI, and world-class leads, we’ve built a company where agents can finally thrive.”

The company’s other co-founders are Chris Miller, chief operating officer and vice president of expansion, and Janice Delci, chief financial officer.

Epique expands business to Canada, Mexico, Australia

The Millers and Delci have guided the company’s rapid expansion.

“Scaling our corporate support team to match [our] hyper-growth while seamlessly expanding across all 50 states and internationally to Canada, Australia, and Mexico takes an incomparable operational infrastructure,” Miller said.

“We have built an enterprise-grade technology ecosystem that allows us to absorb overhead and empower our agents at lightning speed,” he added. “This ranking validates that our disruptive model is working, and it is completely redefining the global industry standard.”

Epique launched its platform in 2023, touting itself as the industry’s first AI-powered brokerage. The startup’s platform provides AI tools for real estate agents to improve their marketing, streamline content creation, and boost engagement with clients and prospects.

Among Epique’s AI tools are:

  • ChatGPT for generation of property descriptions
  • AI-assisted creation of blog posts and agents’ bios
  • Production of Instagram quotes for social media marketing

“When we started Epique, we wanted to build a company that genuinely cared for its agents’ financial and physical well-being,” Delci says. “To see that vision translate into this level of historic record-breaking growth is a beautiful testament to the true power of radical generosity.”

Epique and fellow honorees will be recognized Oct. 14-16 at the 2026 Inc. 5000 Conference & Gala in Dallas.
