New data from the PitchBook/NVCA Venture Monitor reveals a seesaw pattern in the Houston area’s venture capital funding.

VC fundraising by Houston-area companies climbed during the first part of this year compared with the same period last year, according to the latest PitchBook/NVCA Venture Monitor. But from 2023 to 2024, the region’s third-quarter VC haul fell by a double-digit percentage.

In the first three quarters of 2024, Houston-area companies collected $1.24 billion in venture capital, the PitchBook/NVCA Venture Monitor shows. That’s up eight percent from the $1.15 billion raised in the first three quarters of 2023.

A look at third-quarter data tells a different story. During the third quarter of 2024, Houston-area companies reaped $529.45 million in VC funding. That’s down 15 percent from $623 million in the third quarter of 2023.

The U.S. saw VC funding rise from $123.5 billion in the first nine months of 2023 to $131.8 billion during the same period in 2024, PitchBook/NVCA data shows. That works out to a 6.7 percent increase. However, Texas experienced a five percent drop — from $5.4 billion in the first nine months of 2023 to $5.13 billion during the same period in 2024.

“While we see some promising signals with lower rates and platform shifts related to AI, we expect the overall VC landscape to [remain] uncertain and strained for the time being,” says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

The new PitchBook/NVCA report forecasts that VC deal value in the U.S. will hit $175.2 billion this year. This figure is shy of annual fundraising totals during the peak of ultra-low interest rates but exceeds the sum for the pandemic year of 2020.

“Venture deal counts seem to have bottomed, but a meaningful market rebound has yet to occur,” says the report.

Report: Amid difficult market, Houston sees uptick in VC funding

seeing green

Houston-area startups saw a healthy increase in venture capital funding during the first half of 2024 compared with the same period last year, new data shows.

In the first six months of this year, Houston-area startups attracted $760.55 million in VC funding, according to the latest PitchBook-NVCA Venture Monitor. That’s up 17.7 percent from the $645.99 million collected in the first six months of 2023.

Keep in mind that these figures might not match previously reported numbers. That’s because PitchBook regularly adjusts data as new information becomes available.

In light of various factors, such as the ongoing hype over artificial intelligence, fundraising will likely continue to be challenging for U.S. startups as a whole, according to Nizar Tarhuni, vice president of institutional research and editorial at PitchBook, a provider of VC data.

Nonetheless, Bobby Franklin, president and CEO of the National Venture Capital Association (NVCA), points out that American venture capital “is finding its footing in 2024.”

Across the country, VC funding for startups in the first half of 2024 totaled $93.4 billion, up 6.5 percent from the $87.7 billion raised during the same period last year, according to the PitchBook-NVCA Venture Monitor.

“With steadily increasing deal values, especially across early-stage investments, more first-time financings, and increased crossover investor participation, [the second quarter of 2024] was a good one for VC,” says Franklin. “Now it’s up to founders, investors, and regulators to support, rather than stifle, these green shoots as the market heads toward a recovery.”

In the second quarter alone, VC funding in the U.S. jumped from $35.4 billion in 2023 to $55.6 billion in 2024. That’s an increase of 57 percent.

By contrast, the Houston area’s VC funding went in the opposite direction. Startups in the region scored $231.79 million in VC during the second quarter of 2024 vs. $333.17 million during the same period a year earlier. That’s a drop of 30 percent.

So far in 2024, Houston-based Fervo Energy dominates VC hauls for startups in the metro area. In March, the provider of geothermal power announced it had secured $244 million in funding, with Oklahoma City-based oil and gas company Devon Energy leading the round.

Fervo’s latest pot of VC represents more than 30 percent of all Houston-area VC funding during the first six months of 2024.

Tim Latimer, co-founder and CEO of Fervo, says the $244 million investment enables his company “to continue to position geothermal at the heart of 24/7 carbon-free energy production.”

Fervo says the latest VC round will support development of its 400-megawatt geothermal project in Beaver County, Utah. The Cape Station facility is expected to start generating power for the grid in 2026.

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.

Report: Houston snags spot on worldwide ranking of top startup ecosystems in 2024

on the rise

Houston is moving up in the startup world.

The city rises to No. 48 on StartupBlink’s list of the world’s top startup ecosystems for 2024. That’s four spots higher than Houston’s No. 52 ranking on the 2023 list. StartupBlink is an economic research platform.

The Greater Houston Partnership recently noted the ascent of Houston’s ecosystem for startups.

“Houston’s tech scene has made many strides in recent years to set a foundation for startups to thrive, from founding to late stage, across industries,” the partnership says. “With a wealth of incubators coming online and a sharp uptick in venture capital funding, startups now have more landing spots and opportunity for growth in Houston than ever before.”

Elsewhere in Texas:

  • Austin lands at No. 17, up four spots from last year.
  • Dallas-Fort Worth appears at No. 25, up one spot from last year.

The world’s three top-ranked startup ecosystems are the San Francisco Bay Area, New York City, and London.

“As we navigate through 2024, it is undeniably a challenging year for the global startup ecosystem,” Eli David Rokah, CEO of StartupBlink, says in the report. “The funding landscape has entered deeper into a ‘winter,’ signaling a significant

tightening in capital availability for startups. This financial constriction coincides with heightened geopolitical tensions and a noticeable retreat from globalization.”

In this climate, the decision about where to nurture a startup ecosystem is more important than ever, says Rokah.

“As the bubble bursts, and capital becomes increasingly concentrated in specific geographic regions, startups must strategically select their locations to access essential resources and funding opportunities,” he says.

The Senior Member Induction Ceremony will honor the 2026 class at NAI’s Annual Conference June 1-4 in Los Angeles.

Texas takes the No. 1 spot on new energy resilience report

Ranking It

A new report by mineral group Texas Royalty Brokers ranks Texas as the No. 1 most energy-resilient state.

The study focused on four main sources of electricity in hydroelectric dams, natural gas plants, nuclear reactors and petroleum facilities. Each state was given an Energy Resilience Score based on size and diversity of its power infrastructure, energy production and affordability for residents.

Texas earned a score of 71.3 on the report, outpacing much of the rest of the country. Pennsylvania came in at No. 2 with a score of 55.8, followed by New York (49.1) and California (48.4).

According to the report, Texas produces 11.7 percent of the country’s total energy, made possible by the state’s 141,000-megawatt power infrastructure—the largest in America.

Other key stats in the report for Texas included:

  • Per-capita consumption: 165,300 kWh per year
  • Per-capita expenditures: $5,130 annually
  • Total summer capacity: 141,200 megawatts

Despite recent failures in the ERCOT grid, including the 2021 power grid failure during Winter Storm Uri and continued power outages with climate events like 2024’s Hurricane Beryl that left2.7 million without power, Texas still was able to land No. 1 on an energy resilience list. Texas has had the most weather-related power outages in the country in recent years, with 210 events from 2000 to 2023, according to an analysis by the nonprofit Climate Central. It's also the only state in the lower 48 with no major connections to neighboring states' power grids.

Still, the report argues that “(Texas’ infrastructure) is enough to provide energy to 140 million homes. In total, Texas operates 732 power facilities with over 3,000 generators spread across the state, so a single failure can’t knock out the entire grid here.”

The report acknowledges that a potential problem for Texas will be meeting the demands of AI data centers. Eric Winegar, managing partner at Texas Royalty Brokers, warns that these projects consume large amounts of energy and water.

According to another Texas Royalty Brokers report, Texas has 17 GPU cluster sites across the state, which is more than any other region in the United States. GPUs are specialized chips that run AI models and perform calculations.

"Energy resilience is especially important in the age of AI. The data centers that these technologies use are popping up across America, and they consume huge amounts of electricity. Some estimates even suggest that AI could account for 8% of total U.S. power consumption by 2030,” Winegar commented in the report. “We see that Texas is attracting most of these new facilities because it already has the infrastructure to support them. But we think the state needs to keep expanding capacity to meet growing demand."
