Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes three innovators across Houston's energy transition.

Bobby Tudor, board chair of Greentown Labs

Greentown Labs, a climatetech incubator with locations in the Houston and Boston areas, has announced it has received $4 million in funding 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, who also joins the organization as board chair.

“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.” Read more.

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. 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.” Read more.

Casey Brown, executive director of Evolve Houston

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced.

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.” Read more.

13 initiatives receive grant funding from new EV-focused, Houston-led program

driving toward net-zero

Evolve Houston awarded its inaugural microgrants this week to 13 groups, neighborhoods and an individual working to make electric vehicles accessible to all Houstonians.

Launched in 2022, Evolve's eMobility Microgrant Initiative supports community efforts that propose electric vehicle, micro-mobility and charging infrastructure projects in some of Houston's most underserved neighborhoods. The grants ranged from $10,000 to $15,000.

Shell, NRG, CenterPoint, the University of Houston, and the city of Houston are partners in Evolve Houston. GM and bp America helped found the microgrant program.

“The eMobility Microgrant Initiative is a culmination of my vision and the collaborative efforts from many individuals and corporate supporters who recognize the importance of the transition to electric transportation,” Houston Mayor Sylvester Turner says in a statement. “The grant winners we recognized today are trailblazers in their communities, leveraging EV technology to residents in neighborhoods that have been historically underserved.”

Winners of the Round 1 eMobility Microgrants and their proposed projects included:

  • Alliance for Multicultural Community Services: Adding a charging station for the Gulfton area and a youth advocacy initiative
  • Third Ward Real Estate Council & Northern Third Ward Neighborhood Implementation Project: Introducing an interactive “mobility hub” to show what EV infrastructure would look like in Third Ward
  • Coalition of Community Organizations: Bringing eBikes and a charging station in the Fifth Ward
  • Edison Arts Foundation: Installing an EV charging station and green energy awareness at the Edison Center in Fort Bend
  • GROW: Promoting green energy careers to youth in underserved communities through EV education and outreach events
  • Hiram Clarke Fort Bend Houston Redevelopment Authority: Brining a bike share program to Southwest Houston
  • Houston Southeast: Expanding its existing rideshare program that offers free and reduced rides in partnership with Uber EV fleet of electric vehicles
  • Pangea Charging: Adding EV chargers to two Complete Communities apartment complexes/buildings
  • RYDE: Brining a free micro-transit service in the Third Ward, including two electric shuttles that could serve more than 1,000 passengers per month
  • Shawn R. Owens: Introducing a new eBike food delivery service, called Electric Eats, to bring food from from the Third Ward food pantries to the area's senior, underserved and immobile residents
  • South Union Community Development Corporation: Creating a workforce development program for green energy careers
  • The Reflections of Christ's Kingdom (The R.O.C.K.) Church–BroadwayCampus: Adding a DC-Fast charger in the South Houston/Hobby Airport area
  • University of Houston-Downtown: Installing a no-cost EV charging station on campus

“This program is designed to provide launch funding to community-based, EV ecosystem-related projects," says Evolve Houston President and Executive Director Casey Brown. "We see significant opportunities to make meaningful progress by using an exciting new technology that is centered around community-based direction. Our governance system puts the community in charge and knows that the ideas of those that know their communities best will carry the greatest impact.”

Applications for the second round of microgrants are now open.Information can be found here. The application deadline is Friday, September 22, 2023.

Evolve Houston was founded in 2019 through Houston's Climate Action Plan. The nonprofit relaunched in 2022, naming Brown as its new president and executive director. The organization's main goal is to improve air quality, reduce greenhouse gas and to accelerate EV adoption so that half of all new vehicles sold in the Houston area would be EVs by 2030.

Houston nonprofit relaunches, names new leader, and introduces electromobility initiative

evolve evolves

A Houston organization focused on promoting electromobility in Houston has announced some big updates.

Evolve Houston, founded in 2019 through Houston's Climate Action Plan, has relaunched as of its event Thursday, August 18. The nonprofit has also named Casey Brown as the new president and executive director. Formerly at Halliburton and Coretrax, Brown's appointment went into effect this month.

"I am honored to have been appointed by the board to lead Evolve into the next phase of our electric vehicle journey," says Brown. "I look forward to working with our partners to get more electric cars, buses, and bikes on the road, and to publish Evolve's electrification roadmap 2.0 early next year."

Additionally, thanks to funding from Evolve Corporate Catalysts General Motors and bp, the organization has introduced the eMobility Microgrant Initiative, which will facilitate a peer-review process to award microgrants to local electromobility projects. Applications for the grants are now open online and will be accepted through September 16 at 6 pm.

"Evolve Houston is committed to supporting a just transition to a more sustainable transportation system, so all residents can receive the benefits of eMobility," says Grace Millsap, Evolve Houston director of equity and investment, in a news release. "The Greater Houston area has made significant progress in improving livability. We must continue and bring the eMobility revolution to Houston's communities that remain disproportionately in need of a cleaner environment, better services, and diversified economic development.

"Evolve's eMobility Microgrant Initiative will empower and elevate residents' voices, drive further community investment, and prioritize the communities who are most impacted by climate and mobility challenges," she continues.

A community-focused initiative, the Equity Program has been established to address poor air quality and limited access to public transportation in vulnerable communities, per the release. This fall, Evolve will invest the microgrants into community-led efforts that are increasing access to all forms of electric mobility and EV charging stations.

"The Complete Communities Initiative bridges the gap between equity and opportunity for our city's most under-resourced and underserved neighborhoods. Residents living in the Complete Communities have made it clear that its past time to address the transportation and climate change challenges that impact their quality of life," says Shannon Buggs, director of the Mayor's Office for Complete Communities, in the release.

"Increasing chronic air pollution and lack of equitable mobility has disproportionately affected low-to-moderate income neighborhoods," she continues. "With the help of community leaders, the Evolve Houston Equity Program provides a pathway for our City to ensure that every resident lives in a healthy, sustainable and thriving community."

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.
