First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

Houston investors back Austin software startup in $3.25M seed round

money moves

Houston-based investment firm Goose Capital led a $3.25 million round of seed funding revealed recently by Austin-based cleantech software company P6 Technologies.

Other participants in the round are Houston-based investment firms Artemis Energy Partners, Tupper Lake Partners, and Veritec Ventures. The seed round represents the first outside funding for P6, which maintains an office in Houston.

In conjunction with the seed funding:

  • Artemis founder and CEO Bobby Tudor has joined P6’s board of directors. He is an investor in Goose Capital.
  • Paal Kibsgaard, managing partner of Veritec, also has joined the P6 board. Kibsgaard is former chairman and CEO of Houston-based oilfield services company Schlumberger, which now does business as SLB.

Joe Berti, CEO of P6, says Kibsgaard’s “unparalleled experience” will benefit his company.

“Veritec’s strategic vision and active support of energy transition solutions align perfectly with our goals, and I am confident their contribution will be instrumental in shaping our future success,” Berti says in a news release.

Berti is former chief product officer of IBM’s sustainability software unit.

P6, founded in 2022, sells enterprise software to businesses in the energy, transportation fuel, and petrochemical sectors. The startup’s software for product lifecycle assessment enables measurement of the product-level intensity of greenhouse gas (GHG) emissions as energy companies try to achieve sustainability goals.

Tudor applauds P6 for helping fossil fuel-anchored companies reduce GHG emissions.

“Energy is the sector that needs a solution like P6 the most,” says Tudor. “P6 has the right approach and is going to make a step-change improvement to how product-level carbon intensity and GHG emissions are tracked today.”

Angel investors, corporate venture, and more options for Houston startups outside of the traditional venture capital model.

Houston innovator shares investment opportunities outside traditional VC model

guest column

In my last column about tapping into Houston's venture capital ecosystem, I identified the 31 venture capitalists in Houston. By most measures Houston is around 0.5 to 1 percent of US venture capital activity, and that low volume is reflected in the limited number of venture capitalists locally.

But outside of venture capital funds, founders often pull money from other places including angel investors, seed funds and corporate venture capital arms as well as cross-over investors. I got asked this morning by a founder at the Ion, where’s the rest of the list?

Houston has five active corporate venture capital funds, or CVCs, with at least one senior investment professional in Houston with and one with headquarters here (Chevron). A short list of the key investment professionals in the group includes:

There are maybe half a dozen other corporates In Houston that organize around a fund structure and governance of some type, and have been actively investing in venture capital rounds with professionals in Houston. Equinor, a long time corporate investor, Baker Hughes which relaunched a CVC effort in 2021, Mitsubishi has investment professionals in Houston, and Williams which launched a new CVC effort in 2022, as well as Occidental, BHP, and Waste Management which had active CVC efforts in the past that have gone a bit on ice, as did ConocoPhillips, P66 and Schlumberger. Two larger private equity funds Ara Partners and Quantum are active in venture capital deals, but in a more mixed model. This universe would probably add another 30 to 40 Houston based active investment professionals.

The city also has around 10 angel networks, pre-seed funds, pre-seed investors, and accelerators that write checks, typically in the $100K to $1 million range, but either without committed venture funds in an acceleration model, at varying degrees of active, scale, model, and type.

Layering them in no particular order the Houston universe expands by another dozen full time or mostly full time professionals, and a few dozen angels. I’ve included their main contacts below:

These are certainly not large numbers for a city our size, and commensurate with the size of the Houston startup market. But while the cupboard may be a bit bare, it’s not empty. As a founder chasing money, that’s about 75 to 100 names to go chase, with probably double that in active or semi-active angel investors investing through these pools.

Houston alternative energy startup raises $23M series B with global support

money moves

A Houston startup founded based off research coming out of Rice University has closed its series B funding, the company announced this week.

Founded in 2017, Syzygy Plasmonics is a chemical company developing a photocatalyst-powered hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions. As of this week, the company has $23 million more to fund its scaling and grow its team thanks to the closing of its series B financing led by Hong Kong-based Horizons Venture. Equinor Ventures, a new investor, also joined in on the round, along with previous seed and series A investors including The Engine, GOOSE Capital, and Evok Innovations.

"With renewable electricity as an energy source, our technology is cleaner, and because of the stability and activity of our photocatalysts, we can drive dozens of possibilities, tuning reactions that produce different chemicals," says Trevor Best, Syzygy Plasmonics' co-founder and CEO, in a news release. "Our initial product will focus on eliminating emissions from hydrogen production, transforming the industrial process involved in making semiconductors, LEDs and metals. Our system will also enable industries that are consumers of hydrogen fuel cells, like fuel cell vehicles."

The hydrogen-fueled technology originated out of research done over two decades by two Rice University professors, Naomi Halas and Peter Nordlander and further developed by the company's co-founder and CTO, Suman Khatiwada. The technology has the ability to both lower costs and emissions at industrial plants. According to the release, Syzygy's first product focused on hydrogen and the technology has the potential to cut the cost of zero emission hydrogen in half, when compared to other alternatives such as electrolysis.

"There are rules in chemical engineering, and you can't break them, but we follow them in a different way," CEO Trevor Best previously told InnovationMap. "What we're doing is fundamentally different. We're using light instead of heat to drive chemical reactions."

Currently, Syzygy employs 26 people and plans to double its workforce in the next year in order to launch its first full-size, commercial-ready chemical reactors in 2022.

In August of 2019, Syzygy raised its $5.8 million series A and secured Department of Energy ARPA-E and National Science Foundation SBIR Program grants.

"The keys to unlock the potential of hydrogen energy lie within production cost reduction and safety enhancements. Syzygy uses a photocatalysis process to produce H2 on premises, therefore mitigating risks of explosion imposed by the transportation of liquid hydrogen while lowering production costs to increase overall energy efficiency. This technology will be applicable to a wide-range of use-cases, enabling a faster path toward zero-emissions," says Patrick Poon of Horizons Ventures, who is also a new board member at Syzygy.

The international fundraise also attracted interest from Norway-based Equinor's venture arm, which has operations in more than 30 countries.

"We have announced our ambition to become a net-zero energy company by 2050 and in order for society at large to meet its climate goals it will require new solutions and technologies. We are pleased to announce the investment in Syzygy as one potential contributor to help the energy industry reduce emissions as part of our effort to shape the future of energy," says Gareth Burns, head of Equinor Ventures, in the release.

New report ranks Houston as America's No. 2 least safe city

Ranking It

A new study contains bad news for Houston. A report from personal finance website SmartAsset ranks the Bayou City as the second-least safe city in the U.S. among cities with at least 250,000 residents.

Only Memphis ranked worse than Houston.

The 2026 study looked at 83 U.S. cities' violent crimes, property crimes, traffic deaths, and disaster risk.

Houston fared poorly in all four: 11.5 violent crimes per 1,000 residents, 42.9 property crimes per 1,000 residents, 11.6 traffic deaths per 100,000 residents, and “very high” risk for natural disasters, which makes sense in a city prone to tropical weather and flooding.

For all cities in the study, disaster risk and traffic deaths were measured at the county level.

Houston is the only Texas city to rank in the bottom 10. The other cities are:

  • 1. Memphis, Tennessee
  • 2. Houston, Texas
  • 3. St. Louis, Missouri
  • 4. San Francisco, California
  • 5. Kansas City, Missouri
  • 6. Albuquerque, New Mexico
  • 7. Oakland, California
  • 8. Nashville, Tennessee
  • 9. Philadelphia, Pennsylvania
  • 10. Detroit, Michigan

“While no major population center is entirely free from danger, some are more successful than others at creating environments where people can live, work and travel with confidence,” SmartAsset says.

Although this study paints Houston in a poor light, other reports take a more positive view. The "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy ranked as No. 9 in America out of 393 cities with a population of 500,000 or more. Houston also boasts Texas’ 10th best park system, according to its ParkScore Index.

While SmartAsset has bad news for Houston, the Dallas suburb of Plano ranked as the study’s second-safest big city. Compared to Houston, Plano fared well in three of the four categories: 1.5 violent crimes per 1,000 residents, 14.7 property crimes per 1,000 residents, and 6.9 traffic deaths per 100,000 residents. Its only shortcoming is a “relatively high” risk for natural disasters.

Elsewhere in Texas:

  • Fort Worth ranked No. 22
  • Austin ranked No. 26
  • San Antonio ranked No. 54
  • Dallas ranked No. 73

TYBR Health said it plans to use the funding to broaden the B3 GEL System's clinical applications, expand commercialization and conduct studies to evaluate its ability to protect tissue and improve healing outcomes.

"Surgeons are exceptionally good at the structural repair, but the biology that follows is what determines how it heals. That part of the equation has gone largely unaddressed ... There's a shift underway across surgical specialties, from focusing almost entirely on the mechanical repair to also weighing the biological conditions that repair needs to succeed," Tim Keane, co-founder and CEO of TYBR Health, said in the news release. "This financing lets us reach more surgeons and generate the clinical evidence to move that shift forward."

As part of the financing round, Greg Banker of Vensana Capital and Liz Todia Zambory of Mutual Capital Partners will join the TYBR board, alongside independent director Aaron Smith.

"TYBR Health is addressing a gap surgeons have lived with for a long time, with a product that fits the way they already work," Zambory, principal at Mutual Capital Partners, added in the release. "We're excited to co-lead this round and support the company's growth."

TYBR was founded in 2020 and originated from the TMCi’s Biodesign fellowship and participated in the TMC's Accelerator for HealthTech. Its B3 GEL System is a flowable extracellular matrix hydrogel designed to protect tendons, ligaments, muscles, and the surrounding soft tissue while they heal from orthopedic surgery. It received FDA 510(k) clearance last June and launched an Australian clinical trial in the fall.

The B3 GEL System has been used in hand, wrist, shoulder, foot and ankle, and sports medicine procedures since it launched, according to the company, and was first used in the clinical setting earlier this year by Dr. Tammam Hanna with Texas Tech University Health Sciences Center.
