Houston had a strong showing at the 2025 SXSW Pitch showcase in Austin, with two local startups claiming top prizes, including a novel clean-tech startup.
Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.
"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.
Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.
“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.
Little Place Labs, a Houston space data startup, also walked away a winner in the Security, GovTech & Space competition. The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.
"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” Little Place Labs wrote on LinkedIn. "Today, that mission feels even stronger."
One of SWSX's marquee events, the pitch competition, held March 8-10, featured 45 finalists, selected from 589 applicants, in nine categories.
Two other Houston companies were finalists this year:
Trez, a Latino-focused fintech company that uses AI and voice-command payroll through WhatsApp to provide culturally relevant payroll and streamline financial operations for Latino business owners.
Tempesst Droneworx, a veteran-owned software company that's Harbinger software providing real-time contextual intelligence for early warning detection, reducing time to decision and speeding time to action.
Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.
According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.

“The United States has a unique opportunity to lead the global transition to a more sustainable economy. Our office in Houston, the energy transition capital of the world, will be a key component of our sustainability strategy, complementing and integrated with our New York operations,” Alvaro Aguilar, BBVA’s head of strategic projects in the U.S., says in a news release.
The new Houston office is part of BBVA’s corporate and investment banking unit in the U.S. The local hub will partner with BBVA cleantech finance teams in New York City, London, and Madrid.
“We aim to make sustainability a driver of growth, support decarbonization projects, and position BBVA as the leading player in sustainable finance in the United States,” says Javier Rodríguez Soler, BBVA’s global head of sustainability.
BBVA’s U.S. sustainability strategy supports energy companies and those that promote renewable energy, including wind and solar, as well as emerging cleantech options, such as energy storage systems, hydrogen, and carbon capture. It also covers sectors like electric vehicles and energy efficiency.
As of June 2024, BBVA had amassed $279 billion in sustainability business toward its 2025 goal of $332 billion.
Fervo Energy’s flagship project in Utah just generated its first geothermal power.
The electricity is now flowing to the power grid from one of Cape Station’s three generation units, Houston-based Fervo said in a news release. This represents an early but important milestone for the project, as the unit isn’t scheduled to deliver contracted power until Oct. 1.
The achievement, coming four months after Fervo’s roughly $2.2 billion IPO, demonstrates the viability of enhanced geothermal systems (EGS).
“This is a gamechanger for the geothermal industry. It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power,” Tim Latimer, co-founder and CEO of Fervo, said in the release.
The plant’s two other units are scheduled to launch commercial operations on Jan. 1.
The three units make up the project’s 99-megawatt first phase. The next phase, which will add 400 megawatts of capacity, is under construction. The second phase is set to go online in 2028.
Altogether, Cape Station will provide more than 4 gigawatts of capacity, with 900 megawatts already spoken for. The 900 megawatts of contracted electricity would be enough to power nearly 1 million U.S. homes per year.
“Cape Station works because we treated the subsurface like an engineering challenge,” Jack Norbeck, co-founder and chief technology officer of Fervo, added in the release. “Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most.”
Enhanced geothermal continuously draws on heat that’s deep underground, producing electricity around the clock regardless of weather or time of day. That makes it one of the only carbon-free resources capable of constant power delivery, which is critical for data centers and AI infrastructure.
While hundreds of thousands descend on New York for Climate Week, Houston offered a different proposition: come where the work is being built. And last week Houston proved that it’s solving for more energy and fewer emissions; reliability and affordability; speed and durability. We are solving for the “&.”
That equation sharpened last week. On Sept. 14, the Environmental Protection Agency announced it had repealed most 2024 federal carbon-pollution standards for power plants and proposed rescinding remaining greenhouse-gas requirements. Policy matters, but it can pivot. The need to build does not.
HECW is a proving ground, not another conference stop. As I wrote in the Houston Chronicle, Mayor Sylvester Turner planted the seed by insisting we bring people together across the city and industry to drive Houston’s energy future. He knew false choices have no place here: oil and gas and clean technology; prosperity and stewardship; industry and lower emissions.
ECW joined the Climate Week Network this year, connecting Houston to a growing community of more than 500,000 people across 22-plus cities. We now have a seat at the global table—and a responsibility to use it well, building with other cities and the wider clean-energy-solutions world rather than merely talking at them.
The capital is already moving. Since 2017, Houston Energy Transition Initiative member companies have invested more than $95 billion in low-carbon infrastructure, technologies, and research and development. This is where the transition is financed, engineered, tested and operated. But the work requires more than capital. It requires capital allocators who understand the difference between a promising idea and a project that can scale, hire and endure.
Last week was Houston’s show and tell. At ARTECHOUSE, The &Bassador Reception & Awards brought art, technology, culture, philanthropy and energy together. Then the week went beyond downtown.
Sugar Land Town Square became the launchpad for the Metro Innovation Tour & Market: a place for an ecosystem conversation about smart cities, clean energy, equitable access and next-generation mobility before participants boarded three tour routes across greater Houston. It was also the starting point for the Bay City South Innovation Tour to Erthos Project Bravo in Matagorda County, where small groups saw Earth Mount solar modules being installed in real time. The conversation did not end at a panel. It went to the project site.

Approximately 100 startups from around the world pitched at Rice Alliance, Greentown Labs and Halliburton Labs events. At Astros Night at Daikin Park, builders, backers, and believers traded conference rooms for the diamond, creating an experience, not just another event. That is how this work becomes civic fabric.
Activation also means making the energy story felt, not merely explained. AY Young brought the Battery Tour for live performances. It was a reminder that the “Power of &” is not confined to a boardroom or a laboratory. Art and technology, culture and commerce, a new generation and established industry can share the same stage—and help more people see themselves in the work ahead.
Perhaps no activation made the “Power of &” more immediate and real than the Houston, We Have Solutions open mic night. At Creatopia’s Innovation Studio, people took the mic—or simply listened—to share what they were building, the problem they could not stop thinking about, and the connection they hoped to make. It put founders, artists, community builders, researchers and future-makers in one room. That is collaboration in real time: different kinds of expertise meeting before anyone knows exactly what the solution will be.
FOX26 helped carry that story beyond the rooms we convened, hosting Erthos COO Jessica Knight, Mars Materials co-founder Aaron Fitzgerald, and investors Taylor Chapman and Juliana Garaizar to discuss building and backing the future in Houston. Our region should be proud—not as self-congratulation, but because the world is beginning to experience energy and climate solutions firsthand.
This was also a week to give back. Allies in Energy awarded $27,500 to nine organizations advancing energy and climate literacy, civil dialogue, workforce pathways and community action. NRG Energy’s Brighter Communities provided a founding gift to expand the week and fund local grants. It took partners, hosts, sponsors, volunteers, funders and community organizations. That is the “Power of &”: collaboration that leaves a stronger community behind.
The “Power of &” cannot stop at Houston’s city limits. Louisiana’s participation—through its support of the Digital Delta Symposium & Expo—made clear that Houston’s builder ecosystem is regional by necessity. Gulf Coast infrastructure, supply chains, talent, and industrial decisions do not recognize state lines. Neither should our collaboration. If we are serious about building more energy with fewer emissions, we must align capital, resources and opportunity across the entire Gulf Coast.
That same commitment to practical collaboration means listening, learning and adjusting. A builder’s mindset does not protect a plan simply because it came first; it improves the conditions for the work to succeed. That is why Houston Energy and Climate Week will move to April 4–10, 2027—better weather, more time and space for connection, and a stronger city-wide experience for the people building what comes next.
But the real test begins now. Can we keep widening the circle? Can we continue to turn research into projects, pilots into infrastructure, capital into good jobs and climate ambition into results that families and communities can see? Can we make every new solution stronger by bringing in the people who must finance it, build it, operate it, live beside it and benefit from it?
That is the work ahead. Turner understood that Houston does not move forward by asking who wins the argument. It moves forward by asking who is ready to solve the problem. His legacy—and the promise of the “&”—is an invitation to choose collaboration over division, action over performance and possibility over false choices.
The future does not need another city to talk about it. It needs Houston to keep building it. And it will only be built if we keep choosing the "&."
Responding to public outcry, Gov. Greg Abbott has stepped up his campaign against data centers by temporarily halting approval of environmental permits for data center projects.
This and previous moves by Abbott essentially amount to a temporary freeze on the development of new data centers in Texas. His actions come at a time when Texas’ stature as a data center hub has been soaring.
On Monday, Abbott directed the Texas Commission on Environmental Quality to stop issuing permits for data center developments until the Electric Reliability Council of Texas (ERCOT) and Public Utility Commission of Texas complete their review of projects seeking power grid connections.
With regulatory reviews underway and environmental permitting now frozen, state regulators currently cannot approve or deny requests from data center developers, Abbott said.
In a letter to the environmental quality commission’s executive director, Kelly Keel, Abbott said this directive is “consistent with my whole-of-government approach to ensure Texans’ natural resources and way of life are protected.”
Abbott previously ordered the Texas Water Development Board to require data centers to meet reporting requirements for water use. He also told the board to impose penalties for failure to comply with those requirements and to collaborate with ERCOT on its review.
Abbott launched his crackdown on data centers in August by ordering the Public Utility Commission and ERCOT to review data center projects in Texas. The audits will examine all data centers in the queue for interconnections before any more projects can move forward. Interconnections enable data centers to share power, data and computing resources.
In calling for those audits, Abbott cited concerns over data centers’ use of water and electricity, and the centers’ effect on infrastructure expenses and consumers’ utility rates.
“Simply put, Texans must come first,” the governor said.
During next year’s legislation session, Abbott will push for the elimination of state financial incentives for data center projects.
Ed Hirs, an energy fellow at the University of Houston, told Reuters that Abbott was backtracking on “his earlier pronouncements about data centers leading to lower electricity prices.”
Abbott’s actions come amid growing public backlash over data centers. A recent University of Houston survey found that nearly 63 percent of Houston-area residents opposed construction of a data center within a mile of their home.
