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.

by the numbers

Going against national trends, Houston-area startups raised 7 percent less venture capital last year than they did in 2024, according to the new PitchBook-NVCA Venture Monitor report.

The report shows local startups collected $1.75 billion in venture capital in 2025, down from $1.89 billion the previous year.

Houston-based geothermal energy company Fervo Energy received a big chunk of the region’s VC funding last year. Altogether, the startup snagged $562 million in investments, as well as a $60 million extension of an existing loan and $45.6 million in debt financing. The bulk of the 2025 haul was a $462 million Series E round.

In the fourth quarter of last year, Houston-area VC funding totaled $627.68 million. That was a 22 percent drop from $765.03 million during the same period in 2024. Still, the Q4 total was the biggest quarterly total in 2025.

Across the country, startups picked up $339.4 trillion in VC funding last year, a 59 percent increase from $213.2 trillion in 2024, according to the report. Over the last 10 years, only the VC total in 2021 ($358.2 trillion) surpassed the total from 2025.

Nationwide, startups in the artificial intelligence and machine learning sector accounted for the biggest share of VC funding (65.4 percent) in 2025, followed by software-as-a-service (SaaS), big data, manufacturing, life sciences and healthtech, according to the report.

“Despite an overall lack of new fundraising and a liquidity market that did not shape up as hoped in 2025, deal activity has begun a phase of regrowth, with deal count estimates showing increases at each stage, and deal value, though concentrated in a small number of deals, falling just [8 percent] short of the 2021 figure,” the report reads.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”

Female-founded companies in the U.S. raised $38.8 billion, up 27 percent from the previous year, but deal count dropped, according to VC data from PitchBook. Photo via Getty Images.

by the numbers

Female-founded companies in Dallas-Fort Worth may rack up more funding deals and more money than those in Houston. However, Bayou City beats DFW in one key category — but just barely.

Data from PitchBook shows that in the past 16 years, female-founded companies in DFW collected $2.7 billion across 488 deals. By comparison, female-founded companies in the Houston area picked up $1.9 billion in VC through 343 deals.

Yet if you do a little math, you find that Houston ekes out an edge over DFW in per-deal values. During the period covered by the PitchBook data, the value of each of the DFW deals averaged $5.53 million. But at $5,54 million, Houston was just $6,572 ahead of DFW for average deal value.

Not surprisingly, the Austin area clobbered Houston and DFW.

During the period covered by the PitchBook data, female-founded companies in the Austin area hauled in $7.5 billion across 1,114 deals. The average value of an Austin deal: more than $6.7 million.

Historically, funding for female-established companies has lagged behind funding for male-established companies. In 2024, female-founded companies accounted for about one-fourth of all VC deals in the U.S., according to PitchBook.

PitchBook noted that in 2024, female-founded companies raised $38.8 billion, up 27 percent from the previous year, but deal count dropped 13.1 percent, meaning more VC for fewer startups. In Texas, female-founded companies brought in $1.3 billion last year via 151 deals. The total raised is the same as 2023, when Texas female founders got $1.3 billion in capital across 190 deals.

“The VC industry is still trying to find solid footing after its peak in 2021. While some progress was made for female founders in 2024, particularly in exit activity, female founders and investors still face an uphill climb,” says Annemarie Donegan, senior research analyst at PitchBook.

Here's what Houston startups snagged fresh funding last quarter

Q3 in review

With Houston's business and innovation community firmly in its final leg of 2023, it's time to look back on funding from the previous quarter.

While last quarter revealed a decline in VC funding in line with the rest of the country, per PitchBook data, around 60 Houston-area companies secured venture funding in the third quarter. These deals spanned across angel and seed rounds all the way up to a monolith of a series C and unicorn status achievement.

According to InnovationMap reporting, 5 Houston-based companies announced VC funding between July and September. Here's a roundup of these second quarter deals — click on each story to read more.

Houston has another unicorn — a company valued at $1 billion or more — thanks to a recent round of funding.

Axiom Space released the news this week that it's closed its series C round of funding to the tune of $350 million. While the company didn't release its valuation, it confirmed to Bloomberg that it's over the $1 billion threshold. Axiom reports that, according to available data, it's now raised the second-most funding of any private space company in 2023 behind SpaceX.

Saudi Arabia-based Aljazira Capital and South Korea-based Boryung Co. led the round. To date, Axiom has raised over $505 million with $2.2 billion in customer contracts, according to the company.

“We are honored to team with investors like Aljazira Capital, Boryung and others, who are committed to realizing the Axiom Space vision,” Axiom Space CEO and president Michael Suffredini says in a news release. “Together, we are working to serve innovators in medicine, materials science, and on-orbit infrastructure who represent billions of dollars in demand over the coming decade.

Texas university's new flight academy opens at Houston Spaceport

cleared for takeoff

The vehicles may not have “student driver” stickers on them, but Texas Southern University has moved a dozen planes into its new training facility at the Houston Spaceport, opening the way for student flyers to use the facility.

TSU previously reached a deal with Houston Airports and the City of Houston in 2023 to house its prospective Flight Academy at Ellington Field. At the time, TSU had a small fleet of nine planes for student use, but a $5.5 million investment from the city greatly expanded the space available.

The Flight Academy includes a 20,000-square-foot hangar that serves as a TSU satellite campus. The school now has a fleet of 12 Cirrus SR20 aircraft that were acquired last year through state and alumni funding. An additional 4,500 square feet is used as classroom and office space. An 8,000-gallon fuel tank will support flight training operations.

TSU first launched its Aviation Science Management program in 1986 and added a professional pilot program in 2016. The school is now part of the United Airlines pipeline program and has also forged relationships with Delta and Southwest.

“I want to commend Texas Southern University and Houston Airports for their leadership and partnership in advancing aviation education right here in our city,” Houston City Councilwoman Dr. Carolyn Evans-Shabazz in a press release.

“It connects our students to high-paying, high-demand careers in aviation and aerospace. This is how we grow a city in the right way—by investing in workforce development, aligning education with industry and making sure our residents are prepared to lead in the industries of tomorrow. Houston is already a global leader in aerospace and projects like this strengthen that position even further, especially here at Ellington, where innovation and opportunity continue to take flight.”

The City of Houston signed an agreement to continue funding the academy for five years.

Amazon launches ultrafast, 30-minute delivery service across Houston

Amazon Now

More than 20 years after it redefined fast shipping, Amazon is preparing to raise the bar on consumer expectations again by offering to fulfill customers' most urgent product needs in Houston and other parts of the world in a half-hour or less for an extra fee.

The company, which revolutionized online shopping in 2005 with two-day deliveries for Prime members, is rapidly opening small order-processing hubs in dozens of U.S. and foreign cities to cater to shoppers who can't or don't want to wait for cough medicine to relieve flu symptoms or tomatoes for tonight's dinner salad.

The ultrafast service, called Amazon Now, first launched in India last June. Amazon says 30-minute deliveries now are also available in urban areas of the United States, Brazil, Mexico, Japan, the United Arab Emirates, the United Kingdom.

The mini-warehouses devoted to Amazon Now are about the size of a CVS drugstore. They stock about 3,500 products for expedited delivery, including beer, diapers, pet food, meat, nonprescription medications, playing cards and cellphone charging cables.

“We know that customers love speed and always have,” Beryl Tomay, Amazon’s head of transportation, told The Associated Press on Monday. “What we see customers doing, when we offer faster speeds, are they purchase more from Amazon. And Amazon becomes more top of mind for that or other types of items as well.”

In the U.S., the company first tested Amazon Now in Seattle, the home of its headquarters, and in Philadelphia. Most residents of the Dallas-Fort Worth area and Atlanta now have access as well. The service is also live in Dallas-Fort Worth, Denver, Minneapolis, Phoenix, Oklahoma City, Orlando, and dozens of other cities, Amazon said, with New York City and others expected by year-end.

The service charges for Amazon Now start at $3.99 for Prime members, who pay an annual fee of $139, and $13.99 for non-members. A $1.99 small basket fee applies to orders under $15, Amazon said.

The company's bet on a need for speed also comes as some consumers are rebelling against rushed deliveries as they weigh the potential impact on the environment and the workers tasked with preparing orders at a rapid rate.

Amazon’s approach
A relentless focus on speed helped Amazon build a logistics and e-commerce empire. After it made two days the new delivery time normal, Amazon moved into one-day and same-day deliveries for its Prime members. This spring, the company began making 90,000 products available in one hour or three hours at an extra cost.

The scaled down and sped up microhubs that are designed to handle 30-minute orders represent another step in Amazon's pursuit.

Only a handful of people prepare orders from aisles of shelves in the 5,000- to 10,000-square-foot facilities, unlike the sprawling fulfillment centers storing millions of items where Amazon employs a mix of human workers and robotics to pick and pack orders.

Amazon tailors the product inventory to each location and uses artificial intelligence and other technology to analyze what customers buy, as well as when and how often. The most popular U.S. purchases so far include soap, toothpaste, mouthwash, toilet plungers, bananas, limes and wireless earbuds, Amazon said.

The competition
Amazon’s attempt to up the instant gratification ante provides direct competition to on-demand food delivery platforms like Instacart, Uber Eats, DoorDash and Grubhub, which don't have the scale of the e-commerce titan, according to independent retail analyst Bruce Winder.

“What Amazon brings is their prowess in supply chain,” Winder said.

These smaller companies said they don't see Amazon as a threat, though, citing the hundreds of thousands of items they are able to deliver to users' doorsteps by partnering with various merchants and restaurants.

“DoorDash has a mission to empower grocers and retailers and augment their existing footprint, not to replace them,” DoorDash spokesperson Ali Musa said in an emailed statement. “We win only when they win, which is how we can offer over half a million grocery and retail items in under an hour across the country.”

Amazon also is in a race with Walmart to become the retailer that reliably gets orders to online shoppers in under an hour.

For an additional $10 on top of standard delivery charges, shoppers can place Walmart Express Delivery orders from among more than 100,000 products that are guaranteed to arrive in an hour. Many customers, however, are receiving the items under 30 minutes, Walmart CEO John Furner told analysts in February.

Domino's cautionary tale
Companies have promised deliveries in 30 minutes or less before, but the landscape also is littered with failed attempts to break the speed barrier.

The COVID-19 pandemic produced a flurry of companies that promised 10- to 15-minute grocery deliveries from microwarehouses in dense neighborhoods, according to Sucharita Kodali, an analyst at market research firm Forrester Research.

But soaring operating costs, low customer loyalty and the drying up of investor money ultimately caused most to fail before the pandemic was over, analysts said.

Domino’s in 1984 pushed a guarantee that customers would receive their pizzas for free if they weren't delivered in under a half-hour. The company amended the “30 minutes or it’s free” policy after two years, providing only a $3 discount for late deliveries.

The promotion helped Domino’s win market share, but it ended up tarnishing the company's reputation. It dropped the guarantee in December 1993 after a string of crashes and lawsuits involving drivers racing to meet the deadline.

Brad Jashinsky, a retail analyst at information technology research and consulting firm Gartner, said he thinks Amazon should take the pizza chain's experience as a cautionary tale.

“You get in trouble when you start overpromising something like that,” he said.

Amazon won't be making any time guarantees and instead plans to keep customers who chose the 30-minute delivery option updated on the progress of their orders, Tomay said.

“There's no rushing either in our building workers or the gig workers,” she said.

Taking it slow
Kodali thinks Amazon will need a lot of people placing orders around the same time from the same or adjacent apartment buildings for the 30-minute service to be cost-effective.

Consumers may appreciate rapid receipt of products like toilet paper and batteries, but retailers and logistics experts said they also see some online shoppers, especially members of Generation Z, choosing no-rush shipping for products they don't need in a hurry.

Amazon for several years has invited customers to skip one- or two-day delivery and to receive their orders on the same day in as few parcels as possible. Consolidating orders into fewer packages by electing to have them delivered at the same time cuts down on boxes, shipping envelopes and fuel use, analysts said.

“The millennials who came to age in an era that was on fast delivery came to expect it de facto, whereas ... Gen Z is more accepting of a slower speed than previous generations before them,” said Darby Meegan, a general manager at Flexport, a supply chain and logistics company that fulfills orders for thousands of online merchants.

Still, Amazon executives have cited positive early results for Amazon Now in India, where they said Prime members tripled their requests for 30-minute deliveries once they started using the service.

Amazon Now also is attracting more repeat American customers, Tomay said.

“It’s in early days and time will tell,” she said. “I think that it will be interesting to see how it evolves.”

Houston company partners on AI-powered medical support for space missions

AI in space

Houston-based Aexa Aerospace has partnered with SpacePort Australia (SPA) to build medical AI solutions for space crews.

Known as The Hamilton Project, the collaboration aims to complete the training and refinement of a “deductive medical AI model” designed to aid and treat astronauts and space travellers. With limited to no real-time access to doctors on Earth during space missions, the project's goal is to create an AI model that would serve as a medical resource.

“‘The Hamilton Project’ is a sophisticated AI model, integrating academic and clinical knowledge in a unique way,” Aexa founder and CEO Feranando De La Peña Llaca said in a news release. “It is paving the way for future autonomous attending.”

The project is named after NASA flight surgeon Dr. Douglas Hamilton, who participated in 50 missions.

SPA, an independent research organization, will bring its practical medical knowledge and clinical experience to The Hamilton Project, which builds on Australia’s rural and remote medical training programs. SPA founder Dr. Gabrielle Caswell brings 20 years of remote medicine experience that SPA believes will help address the issues that could be encountered in space.

“Rural general practitioners in Australia practice ‘pre-cradle to grave’ medicine, including areas considered sub-specialities in most western countries: OBYN, paediatrics, trauma management, anaesthetics, general surgery, mental health and geriatrics,” Caswell added in the release. “This broad clinical skill set encompasses all stages and phases of human life. And importantly practitioners are also trained in the management of severe trauma. "It is anticipated that doctors and medical staff will become embedded into missions, and all these skills will be required over time, to create successful space economic zones.”

Aexa Aerospace’s previous work includes developing holographic medical devices that have been trialled on the International Space Station. Read more here.
