Greentown Labs, a climatetech incubator with locations in the Houston and Boston areas, has announced it has received funding from a mix of investors.

The $4 million in funding came from both of the Houston and Massachusetts locations. Houston investors included Bobby Tudor, CEO of Artemis Energy Partners and chairman of the Houston Energy Transition Initiative; David Baldwin, co-founder of OpenMinds and TEX-E and partner at SCF Partners; and Rice University. Other investors included MassDevelopment and the City of Somerville.

“The challenges of the energy transition are immense, and the role played by technology incubators like Greentown Labs is essential,” Tudor says in a news release. “We believe this role, which is a partnership between academia, industry, philanthropists, entrepreneurs, and governments, is the best way to get to effective, scalable solutions in a time frame that the urgency of the challenge requires. We need all hands on deck, and this partnership between Massachusetts and Texas can be a role model for others.”

According to Greentown, the funding will support its financial position and contribute to preparing the incubator for its next chapter of supporting its its leadership team prepare for Greentown’s next chapter supporting and growing its 575 startups.

“Greentown’s mission aligns closely with the Houston Energy Transition Initiative’s goal of accelerating global solutions to address the dual challenge of meeting growing energy demand globally while also significantly reducing CO2 emissions,” adds Steve Kean, president and CEO of the Greater Houston Partnership.

With the announcement of the funding, Greentown named its board members, including Tudor, who will serve as Greentown Labs Board Chair. The other Houston-based board members are:

  • David Baldwin, co-founder of OpenMinds and TEX-E; partner atSCF Partners
  • Bob Harvey, former president and CEO of GHP; board member of TEX-E
  • Jane Stricker, senior vice president of energy transition and executive director of HETI

“With this new funding, Greentown is poised to expand its impact across its existing ecosystems and support even more climatetech startups,” adds Kevin Dutt, interim CEO of Greentown Labs. “We believe in the essential role entrepreneurship will play in the energy transition and we’re grateful for the support of our partners who share in that belief and our collective commitment to commercializing these technologies as quickly and efficiently as possible.”

According to Greentown, the incubator plans to announce its new CEO in the coming months.

Houston organization announces major partnership with DOE lab to spur energy innovation commercialization

R&D teammate

A new partnership between the Greater Houston Partnership and Argonne National Laboratory has been established to spur development of commercial-scale energy transition solutions.

The GHP and the Houston Energy Transition Initiative, or HETI, announced that it has signed a memorandum of understanding with Argonne National Laboratory, a federally-funded research and development facility in Illinois. The lab is owned by the United States Department of Energy and run by UChicago Argonne LLC of the University of Chicago.

“The U.S. Department of Energy’s national laboratories have long been the backbone of research, development, and demonstration for the energy sector," Bobby Tudor, CEO of Artemis Energy Partners and Chair of HETI, says in a news release. "The Partnership and HETI, working with our industry members, business community and top research and academic institutions, in collaboration with Argonne, will work across our energy innovation ecosystem to drive this critical effort for our region.”

The partnership, announced at HETI House at CERAWeek by S&P Global, is intended to provide resources and collaboration opportunities between Houston's energy innovation ecosystem — from corporates to startups — to "accelerate the translation, evaluation and pre-commercialization of breakthrough carbon reduction technologies," per the news release.

“A decarbonization center of excellence in Houston is the missing link in the region’s coordinated approach to advancing critical energy transition technologies needed to mitigate the risks associated with climate change, while also promoting economic growth and job creation for the region,” Tudor continues.

Established in 1946, Argonne works with universities, industry, and other national laboratories on large, collaborative projects that are expected to make a big impact on the energy transition.

“Partnerships are essential to realizing net zero goals,” Argonne Director Paul Kearns adds. “We are pleased to extend DOE national laboratory expertise and work with HETI to focus the region’s considerable energy and industrial assets, infrastructure, and talent on broad commercial deployment of needed technologies.”

Houston's history in oil and gas — as well as its momentum in the energy transition space — helped the city claim the top spot in this new report ranking. Photo via Getty Images

New report ranks Houston as the top city for foreign investment

by the numbers

For the second time, a report has analyzed the top markets in the United States for the rest of the world to do business in. This year, that top spot belongs to Houston.

The second annual FT-Nikkei Investing in America ranking, which came out this week from the Financial Times and international financial newspaper Nikkei, put the Bayou City — and six other Texas cities — at the top portion of the ranking. Houston's at No. 1, up four spots from last year, but Austin and four cities in the Dallas area also claim spots in the top 20.

The report looked at four dozen metrics, including workforce and talent, quality of life, openness, business environment, investment trends, and more.

In addition to the ranking, the Financial Times dove a little deeper into what made Houston a standout this year, interviewing many of Houston's most prominent business community members. The article points to the city's storied past as an oil and gas leader, also calling out its busy airports and global shipping ports, as well as its medical technology and aerospace industries. But one of the biggest factors in Houston's business climates success is its opportunity within the energy transition.

“We’re clear in Houston that if we’re going to continue to have prosperity — to the degree to define prosperity as job growth and wealth creation — it’s going to need to come from places other than the incumbent energy business,” Bobby Tudor, chief executive of Artemis Energy Partners, tells FT in the article.

Houston scored an overall 73 out of 100, and its scores across metrics in the report include:

  • Workforce and talent: 68/100
  • Openness: 80/100
  • Business environment: 64/100
  • Foreign business needs: 100/100
  • Quality of life: 47/100
  • Investment trends: 73/100
  • Aftercare: 69/100
Last year's top city was Miami, which ranks at No. 6 this year. Most of the top 10 cities in this year's report represent major gains on the ranking.This report falls in line with others in terms of noticing a change within the green economy in Houston. Earlier this year, personal finance website SmartAsset ranked the Houston metro area as the fifth best place in the U.S. for green jobs, which pay an average of 21 percent more than other jobs. The SmartAsset study found that 2.23 percent of workers in the Houston area hold down jobs classified as “green.”

Houston investors back Austin software startup in $3.25M seed round

money moves

Houston-based investment firm Goose Capital led a $3.25 million round of seed funding revealed recently by Austin-based cleantech software company P6 Technologies.

Other participants in the round are Houston-based investment firms Artemis Energy Partners, Tupper Lake Partners, and Veritec Ventures. The seed round represents the first outside funding for P6, which maintains an office in Houston.

In conjunction with the seed funding:

  • Artemis founder and CEO Bobby Tudor has joined P6’s board of directors. He is an investor in Goose Capital.
  • Paal Kibsgaard, managing partner of Veritec, also has joined the P6 board. Kibsgaard is former chairman and CEO of Houston-based oilfield services company Schlumberger, which now does business as SLB.

Joe Berti, CEO of P6, says Kibsgaard’s “unparalleled experience” will benefit his company.

“Veritec’s strategic vision and active support of energy transition solutions align perfectly with our goals, and I am confident their contribution will be instrumental in shaping our future success,” Berti says in a news release.

Berti is former chief product officer of IBM’s sustainability software unit.

P6, founded in 2022, sells enterprise software to businesses in the energy, transportation fuel, and petrochemical sectors. The startup’s software for product lifecycle assessment enables measurement of the product-level intensity of greenhouse gas (GHG) emissions as energy companies try to achieve sustainability goals.

Tudor applauds P6 for helping fossil fuel-anchored companies reduce GHG emissions.

“Energy is the sector that needs a solution like P6 the most,” says Tudor. “P6 has the right approach and is going to make a step-change improvement to how product-level carbon intensity and GHG emissions are tracked today.”

Houston has responsibility and opportunity to lead the energy transition, say local leaders

the future is here

Houston has an integral role to play in the energy transition, and that role was thoroughly discussed at a recent conference taking place in the Bayou City.

This week, Houston hosted the 10X Summit: The Future Is Here, an event by Ten Across — an organization that focuses on social, economic, and climate change issues across the region around Interstate 10 from Los Angeles to Jacksonville. The three-day conference featured guest speakers who spoke to resiliency, water, the future of energy, and more.

Among these speakers included a handful of Houston researchers, political figures, and innovators — and much of their conversations overlapped related topics and themes, from Hurricane Harvey's legacy and impact on the business community to the role the city will play in the energy transition.

When it comes to the energy transition, here are the key messages Houston leaders shared with 10X attendees.

The energy transition can't happen without Houston

The topic of the energy transition came up right out of the gate for the summit. At the welcome reception on Tuesday, Bobby Tudor, CEO of Artemis Energy Partners and founder and former CEO of Tudor, Pickering, Holt & Co., spoke to the evolution of the industry and how Houston is a major factor in the energy transition's success.

“I don’t think (the energy transition) is going to happen without (Houston)," Tudor says at the fireside chat with Wellington Reiter, executive director of Ten Across. "There's a notion that the transition is inevitable. It’s inevitable — only if our technology continues to advance and improve, only if new assets get deployed, only if capital supports it, and only if the people who know and understand the energy systems are leaning in to make it happen.”

For Tudor, who served as chair of the Greater Houston Partnership in 2020 and made it his mission to communicate the importance of industry evolution during his tenure, Houston businesses motivated by opportunities in business should be looking at the energy transition.

“We’re very good in Houston that, when we see a dollar bill lying on the ground, we bend over and pick it up. Right now, there’s fantastic opportunity in the energy transition space," he says. "We have both a responsibility and an opportunity to be the leaders in the global energy transition.”

Mayor Sylvester Turner in his chat with Reiter on Thursday addressed how some might think that Houston — a headquarters for some of the biggest oil and gas giants — might not be the right city to lead a cleaner energy system, but Turner argued that's exactly why it has to happen here.

“We are the energy capital of the world," he says. "The reality is we have some of the largest greenhouse gas emitters principally located right here in Houston. To the extent of leading an energy transition, the impact is not just locally. The impact is globally.”

Barbara Burger, former president of Chevron Technology Ventures and an energy tech startup adviser, explained how integral the relationship between the energy industry and Houston is.

“As the energy system evolves, so does Houston," she says. “I think it’s our opportunity to lose."

The role of corporate incumbents 

Burger's discussion, which took place on Wednesday, spoke to the role of incumbents — corporations that have been operating in the energy industry for decades — in the transition. She explained how the process can't move forward without these parties.

“The incumbents need to be a part of the energy transition. There are parts of our society that don’t want them to be, and I find that unfortunate," she says. "For one, we’re not going to decarbonize the energy system unless they are a part of it. Two, there are a lot of skills and capabilities and assets in the incumbents to do that.

"What I don’t think the incumbents will do is they won’t lead it," she continues. "Many will be leaders in the new energy system, but they won’t be the ones first up the hill.”

Burger compares the energy and the automotive industries. Tesla acted as a disruptor to major auto companies, and then they followed suit. The disruptors and catalysts the energy industry will be a combination of startups, investors, governments, universities, and employee bases.

“We’re not going to throw away the current energy system," she says. "We’re going to evolve it and repurpose it.”

Houston has the ingredients

Tudor addressed the existing infrastructure — from physical pipes to expertise and workforce — that Houston has, which makes for an ideal location for innovation and progress in the transition.

“For a lot of reasons, it’s very clear that unless Houston leans in, we’re not going to find the solutions we need to transition our energy systems to much lower CO2 emissions," he says.

The GHP established the Houston Energy Transition Initiative in 2021 to concentrate Houston efforts within the future of energy. Tudor says this initiative is focused on what can be done now in town — attracting clean energy startups, developing a hydrogen hub, building facilities for green hydrogen production — to lead to a better future.

“We want to look up 20 years from now and find Houston is still — if not more than ever — the energy capital of the world," he says. "We believe that energy systems globally in 20 years will look quite different from how they look today. And that means Houston will look very different from how it looks today."

Burger emphasized some of the challenges — as well as opportunities — the city has considering its long history within the sector.

“Houston has benefitted from a vibrant, strong U.S. energy industry,” she says. “Keeping strong companies and keeping Houston attractive for the energy business is critical.”

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
