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.”

Innovative Houston energy startup secures $10M investment

fresh funding

A next-generation geothermal tech company announced a new investment from an Oklahoma City-based oil and gas producer.

Fervo Energy secured the $10 million strategic investment from Devon Energy Corporation (NYSE: DVN) this week. The deal creates a partnership between the two entities.

“We are thrilled to have Devon as a partner,” says Tim Latimer, co-founder and CEO of Fervo, in a news release. “Devon is a technology leader with historic and unparalleled expertise in drilling and completing wells. We expect this partnership will help unlock further potential for geothermal as the primary 24/7 renewable energy source.”

Fervo's technology includes drilling horizontal wells for commercial geothermal production as well as distributed fiber optic sensing to geothermal reservoir development, per the release. The strategy allows for more accessible geothermal power.

“We are excited about this partnership with Fervo, an innovator and leader in the enhanced geothermal space,” says David Harris, chief corporate development officer and executive vice president at Devon. “This investment is a good match for Devon’s new energy ventures strategy.”

Former NASA astronaut, official joins Venus Aerospace board

astronaut appointment

Retired Air Force colonel and former NASA astronaut Pamela Melroy, who previously served as deputy administrator of NASA, recently joined the board of directors at Houston-based Venus Aerospace.

Venus Aerospace, a startup founded in 2020, develops rocket engine technology, including rotating rocket detonation engines for hypersonic flights. These engines promise higher power, greater fuel efficiency and lower emissions than conventional rocket engines or jet engines, according to the Interesting Engineering website. The global rocket propulsion market is expected to grow from $9.5 billion in 2025 to $29.9 billion by 2034, according to a forecast by ResearchAndMarkets.com.

“Advanced rocket propulsion has been of interest to me for over a decade, and Venus Aerospace’s recent achievements in demonstrating the stability of rotating detonation rocket engines represent a significant development,” says Melroy, who left NASA earlier this year and is now a self-employed consultant living in Arlington, Virginia.

Melroy, a member of the United States Astronaut Hall of Fame, has built an illustrious career in the aerospace sector. Aside from being a NASA official, she was:

  • One of only two female astronauts to command a space shuttle mission
  • Deputy program manager of Orion space exploration initiatives at aerospace and defense contractor Lockheed Martin
  • Senior technical adviser and director of field operations for the Federal Aviation Administration’s Office of Commercial Space Transportation, where she came up with the first safety guidelines for commercial human spaceflight
  • Deputy director of the Tactical Technology Office at the Defense Advanced Research Projects Agency (DARPA).
  • An adviser for the establishment of the Australian Space Agency

Venus Aerospace said in a news release that as a leader at three federal agencies, “Melroy shaped America’s strategy in space, accelerated commercial space partnerships, and deepened space exploration.”

Sassie Duggleby, co-founder and CEO of Venus Aerospace, called Melroy “a preeminent leader in the world of aerospace.”

In May, Venus Aerospace completed the inaugural test flight of its rotating detonation rocket engine. The startup, whose headquarters is at the Houston Spaceport, says it’s the only company in the world that has manufactured a flight-proven, high-thrust rotating detonation rocket engine.

On the horizon for Venus Aerospace is production of Stargazer M4, a high-speed aircraft capable of two-hour global travel.

Venus Aerospace’s investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. The startup also gets support from the Air Force Research Laboratory (AFWERX), the Air Force, NASA and DARPA.

Jordan Blashek, co-founder and managing partner of America’s Frontier Fund, which backs startups creating breakthrough technologies, said his firm’s investment in Venus Aerospace “underscores our focus on supporting American companies that are revolutionizing industries of the future.”

“With recent hypersonic advancements from China and Russia, safeguarding American innovation and securing our industrial base has never been more urgent,” Blashek added. “Venus Aerospace is poised to redefine hypersonic flight and ensure America’s continued leadership in aerospace innovation.”

Since its founding, Venus Aerospace has raised $78.3 million in investments, according to PitchBook data.
