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.

Houston climatetech startup raises $21.5M series A to grow robotics solution

seeing green

A Houston energy tech startup has raised a $21.5 million series a round of funding to support the advancement of its automated technology that converts field wastes into stable carbon.

Applied Carbon, previously known as Climate Robotics, announced that its fresh round of funding was led by TO VC, with participation from Congruent Ventures, Grantham Foundation, Microsoft Climate Innovation Fund, S2G Ventures, Overture.vc, Wireframe Ventures, Autodesk Foundation, Anglo American, Susquehanna Foundation, US Endowment for Forestry and Communities, TELUS Pollinator Fund for Good, and Elemental Excelerator.

The series A funding will support the deployment of its biochar machines across Texas, Oklahoma, Arkansas, and Louisiana.

"Multiple independent studies indicate that converting crop waste into biochar has the potential to remove gigatons of CO2 from the atmosphere each year, while creating trillions of dollars in value for the world's farmers," Jason Aramburu, co-founder and CEO of Applied Carbon, says in a news release. "However, there is no commercially available technology to convert these wastes at low cost.

"Applied Carbon's patented in-field biochar production system is the first solution that can convert crop waste into biochar at a scale and a cost that makes sense for broad acre farming," he continues.

Applied Carbon rebranded in June shortly after being named a top 20 finalist in XPRIZE's four-year, $100 million global Carbon Removal Competition. The company also was named a semi-finalist and awarded $50,000 from the Department of Energy's Carbon Dioxide Removal Purchase Pilot Prize program in May.

"Up to one-third of excess CO2 that has accumulated in the atmosphere since the start of human civilization has come from humans disturbing soil through agriculture," Joshua Phitoussi, co-founder and managing partner at TO VC, adds. "To reach our net-zero objectives, we need to put that carbon back where it belongs.

"Biochar is unique in its potential to do so at a permanence and price point that are conducive to mass-scale adoption of carbon dioxide removal solutions, while also leaving farmers and consumers better off thanks to better soil health and nutrition," he continues. "Thanks to its technology and business model, Applied Carbon is the only company that turns that potential into reality."

The company's robotic technology works in field, picking up agricultural crop residue following harvesting and converts it into biochar in a single pass. The benefits included increasing soil health, improving agronomic productivity, and reducing lime and fertilizer requirements, while also providing a carbon removal and storage solution.

"We've been looking at the biochar sector for over a decade and Applied Carbon's in-field proposition is incredibly compelling," adds Joshua Posamentier, co-founder and managing partner of Congruent Ventures. "The two most exciting things about this approach are that it profitably swings the agricultural sector from carbon positive to carbon negative and that it can get to world-scale impact, on a meaningful timeline, while saving farmers money."

What to expect from the inaugural TiECon Texas event this week

where to be

Innovators and entrepreneurs will gather in Houston this week to show off their latest advancements in automation during the first-ever TiECon Texas conference at the Ion District.

“Automation is not simply changing how we work. It is redefining how value is created across every industry,” Somesh Singh, president of TiE Houston, said in a release. “Texas has the talent, the infrastructure, and the entrepreneurial spirit to lead this transformation. TiEcon Texas 2026 is where the people building that future will come together to shape it."

The Indus Entrepreneurs (TiE) started in Silicon Valley in 1994 as a two-day seminar, but has grown into a worldwide network of events celebrating technological advancement. TiECon in Houston is a merger of the TiE networks across Texas for one large-scale event taking place at the Ion on Wednesday, October 28, and Thursday, October 29. Tickets are available here.

The event includes a partnership with Hatch Pitch, a founder-first startup showcase that has raised over $20 billion in funding for new companies in the tech industry. Participants will come from industries like space exploration, healthcare, energy, and the AI sector to present their ideas in front of an investor network for possible development.

“Over 80 percent of the teams we have coached have gone on to receive funding,” Greg Wright, founder of Hatch Pitch, added in a release.

In addition, there will be forums and talks on a variety of automation subjects, everything from robotic surgery to automation in government. Educators from Baylor College of Medicine, UTHealth Houston, and the University of Houston plan to discuss the raising of children in a world with extensive artificial intelligence integrated into so many areas. Steven Kean, President and CEO of the Greater Houston Partnership, will give the keynote speech on the Bayou City’s place in these emerging technological spheres.

Singh highlighted how the large-scale disruptions in the technological status quo by the rise of AI could be a sign of potential growth and innovation. The entrepreneurs presenting at TiECon may be the ones to harness the sometimes unsteady AI industry for good causes.

“History shows that periods of technological disruption create extraordinary opportunities for those prepared to act,” he said. “TiEcon Texas is designed to help founders, investors, and enterprises understand where the automation economy is headed and how to participate in building it."

Here are the 10 startups pitching during the TiE Hatch Pitch competition:

Houston startup makes Time's list of the best inventions of 2026

Innovation Station

One of the year's most buzzworthy innovations comes from a Houston-based leader in the energy transition. Utility Global's H2Gen recently made Time magazine’s list of the 300 best inventions of 2026.

The H2Gen is an innovative system that produces low-cost clean hydrogen from water and industrial off-gases. The company says the process doesn’t require electricity, a notable claim since hydrogen production typically consumes a lot of power.

"Using a tubular electrochemical cell containing a proprietary electrolyte and water, the company can turn industrial off-gases into hydrogen at scale—no extra electricity required," writes Time. "Bonus: the process also pulls out carbon dioxide as a separate stream, where it can be captured and kept out of the atmosphere.

CEO Parker Meeks tells Time, it's “a practical pathway to decarbonize existing industrial assets."

The startup is on a roll. It has raised $100 million so far in an ongoing Series D round to offer its decarbonization technology at industrial scale around the world.

H2Gen is joined by 10 other inventions with Texas connections onTime's list, as well as one "special mention."

In North Texas, they are:

Samsung
Plano-based Samsung Electronics America pulled off a hat trick this year, with three products making Time’s list. First up is the Galaxy S26 Ultra smartphone. It packs a more powerful camera, Galaxy AI features, and pro-level content creation tools. But Time singled out its new built-in privacy display as the phone’s “biggest selling point.”

Samsung’s Bespoke AI Family Hub refrigerator also got smarter. When AI first came to the Family Hub in 2024, it could recognize some fresh foods, but you still had to log packaged items by hand, Time noted. Now, with Google Gemini built in, the fridge can identify more than 2,000 packaged foods, read handwritten labels, and warn you when food is about to expire. It then uses what’s inside to build grocery lists and suggest recipes.

And for gamers, there’s the Odyssey G8 monitor. Its 6K resolution leapfrogs the 4K standard, delivering what Samsung calls “exceptional visual clarity and detail” on a screen big enough for gaming and multitasking.

OxeFit
Plano-based OxeFit’s XS1 Peak is about the size of a treadmill but works like an entire gym. It can be set up for strength training, simulated skiing or kayaking, Pilates, or rowing. What makes it stand out is a built-in virtual spotter. According to Time, the machine “uses AI, computer vision and sensors to correct the user’s form, change resistance in the middle of a rep and reduce the weight when the user is struggling, much like a human spotter.”

EssilorLuxottica
EssilorLuxottica, the French eyewear giant whose U.S. headquarters is in Farmers Branch, makes Essilor Stellest lenses. The lenses correct nearsightedness while also slowing the eye growth that makes it worse over time. Stellest is the first and only eyeglass lens authorized by the U.S. Food and Drug Administration to control myopia, Time said. The lenses look like regular glasses but contain 1,021 tiny lenslets. In a U.S. trial of kids ages 6-12, myopia progression slowed by an average of 71 percent over two years compared with standard lenses.

Helpany
Helpany, a startup based in Phoenix that manufactures its devices in DFW, makes Paul, a ceiling-mounted gadget that uses radar and AI to spot subtle changes in how residents move and flag those at higher risk of falling. Helpany says the technology can cut falls by as much as 72 percent.

Aurora Innovation
Aurora, based in Pittsburgh with a corporate and operations hub in Coppell, rolled out its second-generation Driver 2 system in July. By September, Driver 2 trucks had logged more than 500,000 driverless miles without a single at-fault crash, Time reported, and the company expects 200 of them on the road by the end of 2026.

Colossal Biosciences
Dallas-based Colossal Biosciences built an artificial egg by placing an ultra-thin, transparent silicone membrane inside a rigid 3D-printed cup, letting scientists watch the embryo develop. Twenty-six chickens have already been hatched.

In Austin, they are:
Cedar Park-based Hyliion landed on Time’s list with its Karno Power Module, a modular generator designed to produce power wherever it’s needed. The Karno represents a big pivot for the company. Hyliion got its start building electrified powertrains for 18-wheelers before shifting into power generation after acquiring the Karno generator technology from GE Aerospace. Founded in Pittsburgh in 2015, the company relocated to Cedar Park in 2018.

The other Austin-associated honoree is Moment Energy. As more electric vehicles hit the road, a growing number of their batteries are nearing retirement, while demand for power keeps climbing. Moment Energy found a way to tackle both problems at once. The company’s Megafactory 1, which opened in Vancouver, Canada, in June, turns old EV batteries into modular energy storage systems for hospitals, factories, data centers, and other big power users. “Our goal is to make sure these batteries don’t end up in landfills,” founder Edward Chiang told Time.

In the “Special Mentions” category, Austin-based Renzoe Box gained notice for its refillable custom makeup palette for on-the-go people. Licensed architect René Graham designed the box. She graduated from Houston's Rice University, and was born and raised in Dallas.
