Houston-area startups raised more than $1 billion in venture capital during the first half of 2025 — almost double the haul for the first half of last year.

According to the new PitchBook-NCVA Venture Monitor, Houston-area startups raised $417.2 million in the second quarter of this year, compared with $281 million during the same period last year. In the first quarter of 2025, local startups collected $607.5 million in venture capital, compared with $281 million during the same period a year earlier.

Based on those figures, Houston-area startups picked up slightly over $1 billion in VC during the first half of this year, compared with $535 million in the first half of 2024.

Nationally, startups gained almost $70 billion in VC in the second quarter, down 25 percent from the same period a year ago, the PitchBook-NCVA Venture Monitor says.

Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook, explained that “the VC landscape continues to navigate a fragile recovery” and is constrained by economic uncertainty.

However, startups in certain sectors are poised to attract a great deal of attention and venture capital over the next several years, according to the report.

“Companies operating in AI, national security, defense tech, fintech, and crypto — sectors aligned with the administration’s priorities — are attracting disproportionately more investor interest, and this trend will likely continue throughout President Donald Trump’s term,” the report says.

The AI sector accounted for 64 percent of VC deal value in the first half of 2025, according to the report.

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.”

by the numbers

The venture capital haul for Houston-area startups jumped 23 percent from 2023 to 2024, according to the latest PitchBook-NVCA Venture Monitor.

The fundraising total for startups in the region climbed from $1.49 billion in 2023 to $1.83 billion in 2024, PitchBook-NVCA Venture Monitor data shows.

Roughly half of the 2024 sum, $914.3 million, came in the fourth quarter. By comparison, Houston-area startups collected $291.3 million in VC during the fourth quarter of 2023.

Among the Houston-area startups contributing to the impressive VC total in the fourth quarter of 2024 was geothermal energy startup Fervo Energy. PitchBook attributes $634 million in fourth-quarter VC to Fervo, with fulfillment services company Cart.com at $50 million, and chemical manufacturing platform Mstack and superconducting wire manufacturer MetOx International at $40 million each.

Across the country, VC deals total $209 billion in 2024, compared with $162.2 billion in 2023. Nearly half (46 percent) of all VC funding in North America last year went to AI startups, PitchBook says. PitchBook’s lead VC analyst for the U.S., Kyle Stanford, says that AI “continues to be the story of the market.”

PitchBook forecasts a “moderately positive” 2025 for venture capital in the U.S.

“That does not mean that challenges are gone. Flat and down rounds will likely continue at higher paces than the market is accustomed to. More companies will likely shut down or fall out of the venture funding cycle,” says PitchBook. “However, both of those expectations are holdovers from 2021.”

Report: Houston's VC trends so far in 2024 and what to watch for the rest of the year

by the numbers

Houston-based geothermal company Fervo Energy accounted for more than half of the venture capital raised by Houston-area startups in the first quarter of 2024.

The region’s VC haul in the first quarter totaled $462.4 million, according to the PitchBook-NCVA Venture Monitor. That’s up from $290.4 million during the same period in 2023 and from $285.8 million in the fourth quarter of last year. Click here to see the Q1 rounds as reported by InnovationMap.

Fervo’s latest funding round, announced in February, represented $244 million (52 percent) of the region’s VC total for the first quarter of 2024.

A report released in March by PitchBook indicated that VC funding last year for geothermal power reached $431 million across 21 deals. As of late February 25 — four days ahead of the Fervo announcement — $165.5 million in VC funding had been pumped into the geothermal sector this year, according to PitchBook.

“The recent VC deal activity with the geothermal power sector underscores a vibrant and evolving market, but still one that garners far less VC than other renewables,” says the report.

In all, Houston-area startups made 38 VC deals in this year’s first quarter, the PitchBook-NVCA Venture Monitor says. That’s down from 42 in the fourth quarter of 2023 and 43 in the first quarter of 2023. Nationwide, the deal count fell sharply in the first quarter of 2024 vs. the first and fourth quarters of last year.

The PitchBook-NVCA Venture Monitor report shows that nationwide, the $36.6 billion in VC investments recorded during the first quarter of 2024 “remained relatively on pace with the past year.”

“However, it would be a mistake to hyperfocus on the results of a single quarter whose results were a bit farther left on the bell curve than usual. The venture capital … business cycle effectively reset in recent years, and as of early 2024, it still appears to be searching for its level,” says the report.

“It is too early to tell where 2024 is going, but the game is on, and America’s VCs are ready for it,” the report adds. “In 2022, our world changed; in 2023, we accepted it was not changing back; and in 2024, we are building what is next.”

In a bit of good news for the Houston area, the report cites cleantech/energy as one of two sectors that venture capitalists should not overlook. The other sector: cybersecurity.

But in a bit of not-so-good news for the region, the report notes a slowdown in VC deals in the healthcare sector over the past two years in the wake of “pandemic-fueled capital exuberance.”

“Yet the healthcare sector differentiates itself from the rest of the market by demonstrating many unmet needs that could have a profound impact on society, particularly around disease diagnosis and treatment,” the report goes on to say. “On top of the immense opportunity set for disruption within healthcare, investor enthusiasm around AI adoption in drug development further speaks to the demand for better solutions in biotech through groundbreaking innovations.”

Venus Aerospace picks up investment from Lockheed Martin Ventures

space funding

Venus Aerospace, a Houston-based startup specializing in next-generation rocket engine propulsion, has received funding from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, for an undisclosed amount. The product lineup at Lockheed Martin includes rockets.

The investment follows Venus’ successful high-thrust test flight of its rotating detonation rocket engine (RDRE) in May. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

Venus says the Lockheed Martin Ventures investment reflects the potential of Venus’ dual-use technology for defense and commercial uses.

“Venus has proven in flight the most efficient rocket engine technology in history,” Venus co-founder and CEO Sassie Duggleby, a board member of the Texas Space Commission, said in a news release. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

Chris Moran, executive director and general manager of Lockheed Martin Ventures, said Lockheed Martin has been a longtime supporter of early-stage “transformational” technologies.

“Our investment in Venus Aerospace reflects a conviction that next-generation propulsion will define which nations lead in space and defense for decades to come,” Moran added in the release. “We are committed to helping Venus scale this technology and integrate it into critical systems.”

Since its founding in 2020, Venus has secured more than $106 million in funding. In addition to Lockheed Martin Ventures, investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. Supporters of Venus include NASA, the Air Force Research Lab and the Defense Advanced Research Projects Agency (DARPA).
