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.”

Last year, Fervo raised a $138 million series C round to support the completion of power plants in Nevada and Utah and evaluate new projects in California, Idaho, Oregon, Colorado, and New Mexico, as well as in other countries. This latest investment brings the company's total funds raised to $187 million since its inception in 2017.

This Houston neighbor is the fastest growing wealthy suburb in America

By The Numbers

The Houston-area city of Fulshear is booming like nowhere else: It's now the No. 1 fast-growing affluent suburb in the country.

Fulshear's No. 1 status was unveiled in a new GoBankingRates' study that ranked the "30 Fastest Growing Wealthy Suburbs in America" for 2025. The report examined population changes from 2018 to 2023 among cities and towns in major U.S. metro areas with populations between 25,000 and 100,000 residents. Median household income, average home value, and a "livability score" were also calculated for each locale.

Fulshear, located 34 miles west of downtown Houston, experienced the most dramatic population increase out of all 30 cities in the report. Though the suburb only has an estimated population of 42,616 residents, that number has skyrocketed 237 percent during the five-year period.

A Fulshear resident's median income is $178,398 annually, and the average value of a home in the city comes out to $521,157, the report additionally found.

Fulshear was the second fastest growing city in America in 2023. The city's growth is further reflected by the number of new apartments that were built in the area in 2024.

Texas is tops
Texas cities took the top three fastest growing U.S. suburbs for 2025, with Dallas-area cities of Celina (No. 2) and Prosper (No. 3) experiencing wildly different (yet still sky high) population changes. Celina's population ballooned 190 percent to 43,317 residents, while Prosper's grew 81 percent to an estimated 41,660 people.

Other Texas cities that earned spots in the report include Flower Mound (No. 19), Southlake (No. 27), University Park (No. 28) and Colleyville (No. 29), all in the Dallas-Fort Worth area.

"The old adage that everything is bigger in Texas is true, considering the number of Lone Star State suburbs that are quickly growing in population and overall wealth," the report's author wrote.

The top 10 fastest growing wealthy suburbs in America are:

  • No. 1 – Fulshear, Texas
  • No. 2 – Celina, Texas
  • No. 3 – Prosper, Texas
  • No. 4 – Erie, Colorado
  • No. 5 – Clarksburg, Maryland
  • No. 6 – Zionsville, Indiana
  • No. 7 – Redmond, Washington
  • No. 8 – Dublin, California
  • No. 9 – Parkland, Florida
  • No. 10 – Eastvale, California

Rice research breakthrough paves the way for advanced disease therapies

study up

Bioengineers at Rice University have developed a “new construction kit” for building custom sense-and-respond circuits in human cells, representing a major breakthrough in the field of synthetic biology, which could "revolutionize" autoimmune disease and cancer therapeutics.

In a study published in the journal Science, the team focused on phosphorylation, a cellular process in the body in which a phosphate group is added to a protein, signaling a response. In multicellular organisms, phosphorylation-based signaling can involve a multistage, or a cascading-like effect. Rice’s team set out to show that each cycle in a cascade can be treated as an elementary unit, meaning that they can be reassembled in new configurations to form entirely novel pathways linking cellular inputs and outputs.

Previous research on using phosphorylation-based signaling for therapeutic purposes has focused on re-engineering pathways.

“This opens up the signaling circuit design space dramatically,” Caleb Bashor, assistant professor of bioengineering and biosciences and corresponding author on the study, said in a news release. “It turns out, phosphorylation cycles are not just interconnected but interconnectable … Our design strategy enabled us to engineer synthetic phosphorylation circuits that are not only highly tunable but that can also function in parallel with cells’ own processes without impacting their viability or growth rate.”

Bashor is the deputy director for the Rice Synthetic Biology Institute, which launched last year.

The Rice lab's sense-and-respond cellular circuit design is also innovative because phosphorylation occurs rapidly. Thus, the new circuits could potentially be programmed to respond to physiological events in minutes, compared to other methods, which take hours to activate.

Rice’s team successfully tested the circuits for sensitivity and their ability to respond to external signals, such as inflammatory issues. The researchers then used the framework to engineer a cellular circuit that can detect certain factors, control autoimmune flare-ups and reduce immunotherapy-associated toxicity.

“This work brings us a whole lot closer to being able to build ‘smart cells’ that can detect signs of disease and immediately release customizable treatments in response,” Xiaoyu Yang, a graduate student in the Systems, Synthetic and Physical Biology Ph.D. program at Rice who is the lead author on the study, said in a news release.

Ajo-Franklin, a professor of biosciences, bioengineering, chemical and biomolecular engineering and a Cancer Prevention and Research Institute of Texas Scholar, added “the Bashor lab’s work vaults us forward to a new frontier — controlling mammalian cells’ immediate response to change.”

Greentown Labs names new CEO to lead pioneering climate tech incubator

Transition News

Houston and Boston climate tech incubator Greentown Labs has named Georgina Campbell Flatter as the organization’s incoming CEO.

Flatter will transition to Greentown from her role as co-founder and executive director of TomorrowNow.org, a global nonprofit that studies and connects next-generation weather and climate technologies with communities most affected by climate change.

“We are at a transformational moment in the energy transition, with an unprecedented opportunity to drive solutions in energy production, sustainability, and climate resilience,” Flatter said in a news release. “Greentown Labs is, and has always been, a home for entrepreneurs and a powerhouse of collaboration and innovation.”

Previously, Flatter worked to launch TomorrowNow out of tomorrow.io, a Boston-based AI-powered weather intelligence and satellite technology company. The organization secured millions in climate philanthropy from partners, including the Gates Foundation, which helped deliver cutting-edge climate solutions to millions of African farmers weekly.

Flatter also spent 10 years at the Massachusetts Institute of Technology (MIT), where she was a senior lecturer and led global initiatives at the intersection of technology and social impact. Her research work includes time at Langer Lab and Sun Catalytix, an MIT – ARPA-E-funded spin-out that focused on energy storage solutions inspired by natural photosynthesis. Flatter is also an Acumen Rockefeller Global Food Systems Fellow and was closely involved with Greentown Labs when it was founded in Boston in 2011, according to the release.

“It’s rare to find an individual who has impressive climate and energy expertise along with nonprofit and entrepreneurial leadership—we’re fortunate Georgie brings all of this and more to Greentown Labs,” Bobby Tudor, Greentown Labs Board Chair and Chairman of the Houston Energy Transition Initiative, said in a news release.

Flatter will collaborate with Kevin Dutt, Greentown’s Interim CEO, and also continue to serve on Greentown’s Board of Directors, which was recently announced in December and contributed to a successful $4 million funding round. She’s also slated to speak at CERAWeek next month.

“In this next chapter, I’m excited to build on our entrepreneurial roots and the strength of our ever-growing communities in Boston and Houston,” Flatter added in a news release. “Together, we will unite entrepreneurs, partners, and resources to tackle frontier challenges and scale breakthrough technologies.”

Greentown also named Naheed Malik its new chief financial officer last month. The announcements come after Greentown’s former CEO and president, Kevin Knobloch, announced that he would step down in July 2024 after less than a year in the role.
