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.

Experts address Houston's energy transition role — from research to commercialization

HOUSTON @ SXSW

Every part of the energy industry is going to have a role in the energy transition — from the universities where the research and development is happening to the startups and the incumbent industry leaders, as a recent SXSW panel discussed.

“We are well known in Houston for being the energy capital of the world," Jane Stricker, executive director of the Houston Energy Transition Initiative, says as moderator of the panel. "The industry typically comes together with stakeholders to think about the solutions and how to solve this dual challenge of continuing to provide more energy to the world but doing it in a way that significantly reduces emissions at the same time.”

The panel, entitled "Ground Zero: Creating Pathways from Research to Scale Deployment," was put on by HETI, an organization under the Greater Houston Partnership, and took place Sunday, March 12, in Austin at SXSW.

“I often say that I believe Houston is ground zero for the transition because we have this unique combination of assets, infrastructure, innovation, research at universities, and a collective understanding of the importance of energy to people’s lives that allows us to tackle this problem in new ways," she continues.

Sticker was joined by Paul Cherukuri, vice president for innovation at Rice University; Juliana Garaizar, chief development and investment officer at Greentown Labs; and Tara Karimi, co-founder and CTO of Cemvita Factory. The panel highlighted the challenges facing Houston as it promises to lead the energy transition.

For Cherukuri, whose innovation-focused position was newly created when he was appointed to it last August, it's a pivotal moment for research institutions.

"It's really an exciting time in Houston because universities are changing," says Cherukuri. "Rice University itself is changing in dramatic ways, and it's a great opportunity to really plug into the energy transition inside of Houston."

The role he plays, as he explains, is to connect Rice innovators to the rest of the city and the world.

"We have to partner through the accelerators as well as with with companies who can catch what we've made and take it to scale," he continues. "That's uniquely something that we can do in Houston. It's not something that a lot of cities can do."

Representing the scaling efforts is Greentown Labs, and Garaizar explains how the Massachusetts-based organization, which has its second outpost in Houston, connects its member companies to corporate partners that can become funders, pilot partners, customers, and more. But scaling can only be accomplished with the right technologies and the proper funding behind them.

"Sixty percent of the technologies that are going to be used to decarbonize the world haven't yet been invented," she says on the panel. "So, there's a huge pull for technology right now. And we see people who are only on the private equity space now finally invested in a lot of earlier series like series A, but there's still some road to to be made there."

Houston-based Cemvita Factory is in the scale phase, and Karimi explains how she's actively working with companies to apply the company's unique biotechnology to convert CO2 to natural resources to accommodate each customer's needs. Cemvita is on the front lines of interacting with incumbent energy businesses that play a major role in the future of energy.

"The way we communicate with energy companies, we tell them that us to be the innovation arm for you and we work together," Karimi says. "I think it's everybody needs to understand it's a transition. There is no way to just change the way that chemicals are produced just immediately and replace it with something new. It's a transition that needs both aspects."

Japanese company plans $357M solar manufacturing plant in Houston area

coming soon

Japanese solar manufacturing company TOYO Co. Ltd. plans to invest $357 million to bring a 1.5-gigwatt solar cell manufacturing facility to the Houston area.

TOYO’s latest state-of-the-art facility will be co-located at its existing solar module site in Humble, according to a news release from the company. It will produce heterojunction (HJT) solar cells, which are known to be more durable and efficient with a higher heat threshold.

TOYO reports that the new facility will create 400 full-time manufacturing jobs. The project is expected to be completed in 20 months, which includes an initial pilot production.

"Expanding into domestic cell manufacturing is the natural next step in our commitment to creating an integrated onshore solar supply chain from polysilicon to panels," Takahiko Onozuka, chairman and CEO of TOYO, said in the news release. "Co-locating 1.5 GW of HJT cell capacity at our Houston module site significantly optimizes our capital allocation and infrastructure spend.”

TOYO entered the Houston market in 2024 through its acquisition of a majority stake in Solar Plus Technology Texas LLC.

Earlier this year, it began producing solar modules at its 567,140-square-foot plant in Lovett Industrial’s Nexus North Logistics Park. At the time, the company said it planned to expand manufacturing capacity to 6.5 gigawatts.

"The new cell plant reflects TOYO's long-term strategy to build a fully FEOC-compliant domestic manufacturing platform focused on serving the needs of the U.S. utility-scale solar market," Rhone Resch, TOYO's chief strategy officer, added in the release. "By producing premium solar products in the United States, we will be well positioned to meet the market's evolving domestic content requirements while strengthening supply chain security and reliability. Looking ahead, we believe HJT is the optimal technology platform for integrating next-generation perovskite solar cells, which we expect will drive the next major advancement in solar conversion efficiency and support TOYO's long-term technology roadmap.”

New survey reveals concerns over AI data center growth in Houston

data findings

A new report out of the University of Houston shows that area residents remain wary of the long-term effects of operating data centers.

The recent survey from the University of Houston’s latest SPACE City Panel, conducted by the Center for Public Policy at the Hobby School of Public Affairs, shows that while 85 percent of Houston-area residents use AI, nearly 63 percent oppose the construction of AI data centers within 1 mile of their homes.

Respondents’ concerns centered around data centers’ high energy demand and the area’s power grid reliability. According to the survey, 32 percent of residents who oppose local data center projects would be more likely to support the centers if they relied on renewable energy over fossil fuels.

“Respondents understand that AI can bring economic and educational benefits, but they are also concerned about the physical infrastructure needed to fuel AI, especially data centers,” Soran Mohtadi, post-doctoral fellow at the Hobby School and a researcher on the report, said in a news release. “This physical infrastructure demands more electricity and water, leading to environmental impacts.”

Experts estimate that 6.5 gigawatts of data center capacity will be added to the Texas grid by 2030. And Houston’s data center capacity is predicted to more than double by 2028.

The Electric Reliability Council of Texas also projects electricity demand could reach 218 gigawatts by 2031, which would be more than double the record peak set in August 2023. Data centers are expected to account for 86 gigawatts of that new demand.

Survey respondents also said they are concerned about the state's future water supply, given the large amounts of water that data centers need to stay cool.

In terms of who’s responsible for that issue, 57.6 percent of respondents said they put the onus on Texas lawmakers, while 31.5 percent say tech companies should be responsible.

Additionally, more than 75 percent of respondents believed that data center developers and technology companies—not residents—should bear the cost of infrastructure upgrades to support data centers.

“Every decision legislators make has implications on residents’ everyday lives and local infrastructure now and in the future,” Maria P. Perez Arguelles, lead researcher on the report and research assistant professor at the Hobby School, added in the news release. “This issue is going to become more important in years to come, so this is just the beginning.”
