A Houston biotech company has won the Texas A&M New Ventures Competition (TNVC). Taurus Vascular took home $30,000 for its first-place victory.

Taurus Vascular is working on a new solution to stopping abdominal aortic aneurysms (AAA) before they rupture and become potentially fatal. The company arose out of the TMC Innovation Biodesign Program. Fellows Matthew Kuhn and Melanie Lowther had a year to bring a company to fruition. The highly qualified team can boast of Kuhn’s more than 40 patents and Lowther’s former role as director of entrepreneurship and innovation at Texas Children’s Hospital.

The competition’s intense process included presenting to commercialization experts across several rounds. In fact, vetting takes four months and includes coaching to help competitors thrive in their pitches. Read more.

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. Read more.

A clinical-stage Houston biotech company has expanded its collaboration with Houston Methodist Research Institute, or HMRI.

Coya Therapeutics is already sufficiently established to be publicly traded since late 2022, but there’s always room to grow. With the help of a new sponsored research agreement, Coya will work on multiple initiatives. Coya is led by co-founder and CEO Howard Berman, who was inspired by his father’s dementia diagnosis.

"I was interested in what I could do for my dad," Berman said on the Houston Innovators Podcast, explaining that he met with renowned Houston Methodist researcher and neurologist, Dr. Stanley Appel, who showed him that he was not only working on treatments that could help Berman’s now-deceased father, but that he’d been able to stop the progression of ALS.

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.

Houston startup with unique vascular innovation enrolls subjects in new trial

medical device momentum

A Houston-based company has enrolled the initial subjects in a first-of-its-kind trial.

VenoStent was created to improve vascular surgery outcomes for patients undergoing arteriovenous fistula (AVF) creation surgery.

“When a vein is connected to an artery, as in AVF creation, the vein experiences a 10x increase in pressure and flow that is traumatizing to veins. Many fail to become usable for dialysis,” Geoffrey Lucks, VenoStent COO and co-founder, says in a news release.

Enter VenoStent’s SelfWrap Bioabsorbable Perivascular Wrap, better known as simply SelfWrap. In May 2023, SelfWrap gained FDA approval to begin its US IDE Study, SAVE-FistulaS: The SelfWrap-Assisted ArterioVEnous Fistula Study.

Roughly half a million Americans need hemodialysis just to survive another day. Nearly all of those patients require a vascular access creation surgery, but the procedure has a 50-percent failure rate in its first year. VenoStent and SelfWrap are aimed at improving those odds. It works by using the body’s own healing mechanism.

SelfWrap is a flexible, bioabsorbable vascular wrap that helps to recreate the arterial environment in veins. Over time, the body replaces the SelfWrap with venous tissue.

The company has begun to enroll patients for what will eventually be a 200-subject study. Some of those people have radiocephalic fistulas, others have brachiocephalic ones. This is important, because it will likely prove that the technology works for most types of AVFs. The sites for this clinical trial are at the Surgical Specialists of Charlotte, P.A. in Charlotte, NC, and the Cardiothoracic and Vascular Surgeons in Austin.

“While it’s ambitious and sets a high bar for FDA Approval, we owe it to the chronic kidney disease (CKD) patient community to provide the highest level of clinical evidence,” Timothy Boire, CEO and cofounder, says in the release. “We’re confident based on years of preclinical and clinical data that we’ll demonstrate superiority to standard of care with this breakthrough technology.”

VenoStent recently completed a $16 million Series A, financed by Good Growth Capital and IAG Capital. This is the first-ever randomized controlled trial of a medical device designed to improve outcomes from arteriovenous fistula (AVF) creation surgery in the United States.

Activate named Jeremy Pitts as the Houston managing director this month. The nonprofit, which announced its new Houston program earlier this year, was founded in Berkeley, California, in 2015 to bridge the gap between the federal and public sectors to deploy capital and resources into the innovators creating transformative products.

For Activate Houston, the challenge is to focus on finding and supporting innovators within the energy sector.

"There are so many reasons to be excited about the energy transition and overall innovation ecosystem in Houston — the region's leadership in energy and desire to maintain that leadership through the energy transition, the many corporations leading the charge to be part of that change who are speaking with their actions and not just their words, the incredible access to talent, the region's diversity, the list goes on and on," Pitts tells InnovationMap.

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. Read more.

While not based in Houston, Kevin Knobloch, who served as chief of staff of the United States Department of Energy in President Barack Obama’s second term, is definitely going to be someone to know in the innovation ecosystem. He will be CEO of Greentown Labs, effective September 5. In his role, Knobloch will oversee both Greentown locations in Houston and Somerville, Massachusetts, outside of Boston.

“I’m honored and thrilled to have the opportunity to once again pass the leadership baton,” Greentown Co-Founder Jason Hanna says, who has been serving as interim CEO. “Especially so given Kevin’s incredible record of climate leadership. I’m excited for the future of this organization and the impact he can make as Greentown enters the second decade of its climate mission.” Read more.

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.

Houston health tech startup secures $16M series A, prepares for first U.S. clinical trials

money moves

Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.

NASA unveils Artemis III astronauts at Johnson Space Center in Houston

To the moon

NASA on Tuesday, June 9, revealed the crew for its Artemis III mission, the next step in the space agency's plan to eventually land astronauts on the moon.

The announcement came two months after Artemis II's record-breaking trip around the moon that surpassed the distance record of Apollo 13.

NASA's Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency's Luca Parmitano won't fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with two lunar landers.

“To the Artemis III crew, we wish you Godspeed on the journey ahead,” said NASA administrator Jared Isaacman.

Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin are racing to deliver the lunar landers. The two-week demo is targeted for 2027. Blue Origin suffered a recent setback when its massive rocket exploded during an engine-firing test on the launch pad in Florida, shaking nearby homes and illuminating the sky with an orange fireball.

NASA's Jeremy Parsons said the setback is a learning opportunity and that the space agency is confident Blue Origin's rocket will be ready in time.

NASA's Artemis program aims to return astronauts to the moon's surface for the first time since the 1970s. A recent revamp of the program announced by Isaacman aims to fast-track it similarly to the Apollo era, adding the upcoming spaceflight around Earth before eyeing a lunar landing in 2028.

“We are certainly humbled as a crew to be able to be your crew that executes this Artemis III mission in space,” said Bresnik, Artemis III commander.

Added Douglas, mission specialist: “My brain — it is going a mile a minute right now. But my heart, it is so warm. It is so full."

In May, NASA awarded hundreds of millions of dollars in contracts to four companies, including Blue Origin, to build landers, rovers and drones for a future moon base. Isaacman said the goal of the moon base is to lay the foundation for a Mars expedition.
