Houston VC funding surged in 2024, fueled by major Q4 activity

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.”

show me the money

A Houston company that's responding to rising energy demand by harnessing geothermal energy through its technology has again secured millions in funding. The deal brings Fervo's total funding secured this year to around $600 million.

Fervo Energy announced that it has raised $255 million in new funding and capital availability. The $135 million corporate equity round was led by Capricorn’s Technology Impact Fund II with participating investors including Breakthrough Energy Ventures, CalSTRS, Congruent Ventures, CPP Investments, DCVC, Devon Energy, Galvanize Climate Solutions, Liberty Mutual Investments, Mercuria, and Sabanci Climate Ventures.

The funding will go toward supporting Fervo's ongoing and future geothermal projects.

“The demand for 24/7 carbon-free energy is at an all-time high, and Fervo is one of the only companies building large projects that will come online before the end of the decade,” Fervo CEO and Co-Founder Tim Latimer says in a news release. “Investors recognize that Fervo’s ability to get to scale quickly is vital in an evolving market that is seeing unprecedented energy demand from AI and other sources.”

Additionally, Fervo secured a $120 million letter of credit and term loan facility from Mercuria, an independent energy and commodity group that previously invested in the company.

“In surveying power markets across the U.S. today, the need for next-generation geothermal is undeniable,” Brian Falik, group chief investment officer of Mercuria, adds. “We believe in Fervo not just because their EGS approach is cost-effective, commercially viable, and already being deployed at scale, but because they set ambitious targets and consistently deliver.”

In February, Fervo secured $244 million in a financing round led by Devon Energy, and in September, the company received a $100 million bridge loan for the first phase of its ongoing project in Utah. This project, known as Project Cape, represents a 100x growth opportunity for Fervo, as Latimer explained to InnovationMap earlier this year. As of now, Project Cape is fully permitted up to 2 GW and will begin generating electricity in 2026, per the company.

Other wins for Fervo this year include moving into its new headquarters in downtown Houston, securing a power purchase agreement with California, growing its partnership with Google, and being named amongst the year's top inventions by Time magazine.

Expert: How to best repurpose Houston’s infrastructure for a clean energy future

guest column

Houston, often dubbed the “Energy Capital of the World,” is at a pivotal moment in its history. Known for its vast oil and gas reserves, the city is now embracing a new role as a leader in the clean energy transition. This shift is not just about adopting new technologies but also about creatively repurposing existing infrastructure to support sustainable energy solutions.

Houston’s offshore oil wells, many of which are old or abandoned, present a significant opportunity for carbon capture. By repurposing these wells, we can sequester carbon dioxide, reducing greenhouse gas emissions and mitigating climate change. This approach not only utilizes existing infrastructure but also provides a cost-effective solution for carbon management. According to the Greater Houston Partnership, initiatives like these are crucial as Houston aims to lower its climate-changing greenhouse gas emissions. Exxon estimates that just their proposed CCS hub could capture and store 50 million metric tons of CO2 annually by 2030 and 100 million metric tons by 2040.

The proximity of abandoned offshore platforms to the coast makes them ideal candidates for renewable energy substations. These platforms can be transformed into hubs for wind, solar or tidal energy, facilitating the integration of renewable energy into the grid. This repurposing not only maximizes the use of existing structures but also minimizes environmental disruption.

Decommissioned pipelines, which are already in place, offer a ready-made solution for routing renewable energy cables. By using these existing rights of way, Houston can avoid disturbing additional seafloor and reduce the environmental impact of new cable installations. This strategy ensures a smoother transition to renewable energy infrastructure. The U.S. Energy Information Administration notes that Texas, including Houston, leads the nation in wind-generated electricity, highlighting the potential for further renewable energy development.

Onshore oil and gas facilities in Houston also hold potential for clean energy repurposing. Wells that were drilled but never used for oil or gas can be adapted for geological thermal energy storage. This process involves storing excess renewable energy in the form of heat, which can be retrieved when needed, providing a reliable and sustainable energy source. This innovative use of existing wells aligns with Houston’s broader energy transition strategy, which aims to leverage the city’s industrial expertise for a low-carbon future.

Once the land has been remediated, old and abandoned oil fields can be converted into solar farms. This transformation not only provides a new use for previously contaminated land but also contributes to the generation of clean, renewable energy. Solar farms on these sites can help meet Houston’s energy needs while supporting environmental restoration. The Environmental Protection Agency in recent years recognized Houston as the top city in the U.S. for green energy usage, with annual green power usage topping 1 billion kilowatt-hours in 2021.

Houston’s journey towards a clean energy future is a testament to the power of innovation and adaptability. By repurposing existing infrastructure, we can create a sustainable energy landscape that honors the city’s industrial past while paving the way for a greener tomorrow. These strategies highlight the potential for Houston to lead in the clean energy transition, setting an example for cities worldwide.

Houston company secures $100M for 'world’s largest geothermal energy plant'

loan guaranteed

Houston-based geothermal energy company Fervo Energy has secured a $100 million bridge loan for the first phase of its ongoing project in Utah.

The loan came from an affiliate of Irvington, New York-based X-Caliber Rural Capital. Proceeds will support construction of Fervo’s Cape Station project, which is being touted as the world’s largest geothermal energy plant.

The first phase of Cape Station, which is on track to generate 90 megawatts of renewable energy, is expected to be completed in June 2026. Ultimately, the plant is supposed to supply 400 megawatts of clean energy by 2028 for customers in California.

“Helping this significant project advance and grow in rural America is a true testament to how investing in communities and businesses not only has local influence, but can have a global, long-lasting impact by promoting sustainability and stimulating rural economies,” Jordan Blanchard, co-founder of X-Caliber Rural Capital, says in a news release.

X-Caliber Rural Capital is an affiliate of commercial real estate financing company X-Caliber Capital Holdings.

Fervo says its drilling operations Utah’s Cape Station show a 70 percent reduction in drilling times, paving the way for advancement of its geothermal energy system.

Tim Latimer, co-founder and CEO of Fervo, says his company’s drilling advancements, purchase deals, transmission rights, permit approvals, and equipment acquisitions make Fervo “an ideal candidate” for debt financing. In May, Latimer joined the Houston Innovators Podcast to discuss the company's growth and latest project.

With a new office in downtown Houston, Fervo recently signed up one of the country’s largest utilities as a new customer and expanded its collaboration with Google.

To date, Fervo has raised $531 million in venture capital funding, per Crunchbase data.

big tech

A Houston company has signed a new agreement with Meta Platforms Inc. — Facebook's parent company — to power the tech giant's data center growth.

Houston-based Sage Geosystems agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta. The companies made the announcement this week at the United States Department Energy’s Catalyzing Next Generation Geothermal Development Workshop.

The deal is significant because it's the first next-generation geothermal project located to the east of the Rocky Mountains, the companies report in a news release.

“This announcement is the perfect example of how the public and private sector can work together to make the clean energy transition a reality,” Cindy Taff, CEO of Sage Geosystems, says in the release. “We are thrilled to be at the forefront of the next generation of geothermal technology and applaud the DOE for supporting the commercialization of innovation solutions.

"As energy demand continues to grow, the need for reliable, resilient and sustainable power is paramount and our partnership with Meta underscores the critical need for innovative and sustainable energy solutions like ours,” she continues.

The project's first phase will aim to be operating in 2027. The plans reflect how geothermal is being recognized as a growing carbon-free energy source in the country, and how Meta is committed to clean energy initiatives.

“The U.S. has seen unprecedented growth in demand for energy as our economy grows, the manufacturing sector booms thanks to the Biden-Harris Administration’s Investing in America agenda, and new industries like AI expand,” U.S. Energy Deputy Secretary David Turk says. “The Administration views this increased demand as a huge opportunity to add more clean, firm power to the grid and geothermal energy is a game-changer as we work to grow our clean power supply.”

Sage's technology — called Geopressured Geothermal System — works deep in the earth to develop energy storage and geothermal baseload power.

“Meta thanks the Department of Energy’s leadership on promoting and supporting the exploration of new energy sources like geothermal," Urvi Parekh, head of renewable energy at Meta, says. "That leadership supports Meta’s goal to enable the addition of reliable, affordable, and carbon-free power to the grid with this geothermal energy deal. We are excited to partner with such an innovative company like Sage Geosystems that is a proven leader in geothermal development on this project and beyond.”

Sage recently teamed up with a utility provider for an energy storage facility in the San Antonio metro area to build its three-megawatt EarthStore facility.

The company is also working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas, which is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

Texas is the 4th hardest working state in America, report finds

Ranking It

It's no secret that Texans are hardworking people. To align with the Labor Day holiday, a new WalletHub study asserts that the Lone Star State is one of the five most hardworking states in America for 2025.

The report ranked Texas the fourth most hardworking state this year, indicating that its residents are working harder than ever after the state fell into seventh place in 2024. Texas previously ranked No. 4 in 2019 and 2020, slipped into No. 5 in 2021 and 2022, then continued falling into sixth place in 2023. But now the state is making its way back to the top of the list.

WalletHub's analysts compared all 50 states based on "direct" and "indirect" work factors. The six "direct" work factors included each state's average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, and other data. The four "indirect" work factors consisted of workers' average commute times, the share of workers with multiple jobs, the annual volunteer hours per resident, and the average leisure time spent per day.

North Dakota landed on top as the most hardworking state in America for 2025 for another year in a row, earning a score of 66.17 points out of a possible 100. For comparison, Texas ranked No. 4 with 57.06 points. Alaska (No. 2), South Dakota (No. 3), and Hawaii (No. 5) round out the top five hardest working states.

Across the study's two main categories, Texas ranked No. 5 in the "direct" work factors ranking, and earned a respectable No. 18 rank for its "indirect" work factors.

Broken down further, Texans have the second-longest average workweek hours in America, and they have the 12th best average commute times. Texans have the 6th lowest amount of average leisure time spent per day, the report also found.

According to the study's findings, many Americans nationwide won't take the chance to not work as hard when presented with the opportunity. A 2024 Sorbet PTO report found 33 percent of Americans' paid time off was left unused in 2023.

"While leaving vacation time on the table may seem strange to some people, there are plenty of reasons why workers choose to do so," the report's author wrote. "Some fear that if they take time off they will look less dedicated to the job than other employees, risking a layoff. Others worry about falling behind on their work or are concerned that the normal workflow will not be able to function without them."

The top 10 hardest working states are:

  • No. 1 – North Dakota
  • No. 2 – Alaska
  • No. 3 – South Dakota
  • No. 4 – Texas
  • No. 5 – Hawaii
  • No. 6 – Virginia
  • No. 7 – New Hampshire
  • No. 8 – Wyoming
  • No. 9 – Maryland
  • No. 10 – Nebraska
