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.

A Houston startup that is developing a technology to detect methane leaks has moved on to phase two in Chevron's unique business accelerator.

Aquanta Vision Technologies, a Houston-based climate-tech startup, was selected to participate in the scale-up phase of Chevron Studio, a Houston program that matches entrepreneurs with technologies to turn them into businesses. Aquanta's computer vision software completely automates the identification of methane in optical gas imaging, or OGI. The technology originated from Colorado State University and CSU STRATA Technology Transfer.

Babur Ozden, a tech startup entrepreneur, along with Marcus Martinez, the lead inventor and Dan Zimmerle, co-inventor and director of METEC at CSU Energy Institute, came up with the technology to identify the presence and motion of methane in live video streams. Currently, this process of identifying methane requires a human camera operator to interpret the images. This can often be unreliable in the collection of emissions data. Continue reading.

Houston advance care company closes $7M funding round

fresh funding

Houston-based digital advance care planning company Koda Health has closed an oversubscribed $7 million series A funding round.

The round, led by Evidenced, with participation from Mudita Venture Partners, Techstars and Texas Medical Center, will allow the company to scale operations and expand engineering, clinical strategy and customer success, according to a news release.

“This funding allows us to create more goals-of-care product lines, expand our national footprint, and bring goal-concordant care to millions more patients and families," Tatiana Fofanova, co-founder and CEO of Koda Health, said in the release.

Koda Health, which was born out of the TMC's Biodesign Fellowship in 2020, has seen major growth this year and said it now supports more than 1 million patients nationwide. The company integrated its end-of-life care planning platform with Dallas-based Guidehealth in April and with Epic Systems in July. Users of Epic's popular Mychart system and Guidehealth's clinically integrated networks can now document and share their care preferences, goals and advance directives for health systems using Koda Health's platform. It also has partnerships with Cigna, Privia and Memorial Hermann.

The company shared that the recent series A "marks a pivotal moment," as it has secured investments from influential leaders in the healthcare and venture capital space.

“Koda is the only company combining technology and service to deliver comprehensive solutions that help health plans, providers, and health systems scale goals-aligned care. With satisfied customers expanding their partnerships and policy shifts reinforcing the need for patient-centered care that also contains costs, we couldn’t be more excited to support the Koda team and their vision,” Sean Glass, managing partner at Evidenced, said in the release.

According to the company, a recent peer-reviewed study with Houston Methodist ACO showed that the platform can have a major impact on palliative care results and costs. The findings showed:

  • 79 percent reduction in terminal hospitalizations
  • 20 percent decrease in inpatient length of stay
  • 51 percent increase in hospice use among decedents
  • Nearly $9,000 in average savings per patient

“Patients long for clarity, families deserve peace of mind, and providers demand ease of use,” Dr. Desh Mohan, chief medical officer of Koda Health, added in the release. “At Koda, we make it possible to deliver all three — transforming Advance Care Planning into a compassionate, ongoing dialogue that honors patients and supports families every step of the way.”

Koda Health also closed an oversubscribed seed round for an undisclosed amount last year, with investments from AARP, Memorial Hermann Health System and the Texas Medical Center Venture Fund. Read more here.

TXSE Group wins SEC approval for Texas Stock Exchange to start in 2026

Trading in Texas

The U.S. Securities and Exchange Commission has given the go-ahead to the Dallas-based Texas Stock Exchange to operate as a national securities exchange, clearing the way for the TXSE to begin trading stocks and exchange-traded products by early 2026.

TXSE is the first fully integrated national securities exchange to receive SEC approval in decades. A release calls it "a milestone decision" that restores competition in America's public markets.

The organization has already laid the groundwork with an exchange platform utilizing the appropriate hardware and software that will function in an evolving trading and regulatory environment.

TXSE, which opened its headquarters in Dallas in spring 2025, will launch trading as well as ETP and corporate listings for companies that meet their standards and are fully transparent. Their goal is to compete with the NYSE and NASDAQ by building up a large roster of newly listed companies.

"Today's approval marks a pivotal moment in our effort to build a world-class exchange rooted in alignment, transparency, and partnership with issuers and investors," says TXSX founder and CEO James H Lee. "Real competition for corporate listings in the United States has finally arrived."

According to the release, TXSE's mission is to reverse a decades-long decline in the number of U.S. public companies by reducing the burden of going and staying public while maintaining high quantitative standards in the industry.

They've already pushed for legislative and legal reforms to strengthen Texas' pro-business environment and establish the state as the premier jurisdiction for corporate headquarters, listings, and exchange operators — working alongside Texas leadership to advocate on behalf of issuers and investors to reform policy.

"As the one and only national securities exchange built and headquartered in Texas, we are proud to have been the catalyst for the development of capital markets in our great state," Lee says.

TXSE's founding investors include financial institutions, retail, and institutional investment organizations, including BlackRock, Citadel Securities, and Charles Schwab, as well as major liquidity providers and corporate executives from across the U.S.

TXSE will be one of three exchanges to join Texas' so-called economic hub Y’all Street, along with the New York Stock Exchange and NASDAQ.
