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.

Researchers at Rice University, the University of Houston and other Texas universities have been awarded the Department of Energy’s Early Career Award for their work in quantum science, AI and more.

Each professor who received the honor will be awarded $875,000 over five years to continue their work.

The Houston-area recipients include:

  • James Shee, assistant professor of chemistry at Rice University
  • Tony Geng, assistant professor of electrical and computer engineering at Rice
  • Naihao Chiang, assistant professor in the department of chemistry at the University of Houston

For Shee, the award will support his work to advance a “first principles platform to simulate the quantum dynamics of chemical systems of relevance to sustainable energy consumption and generation,” according to a news release from Rice.

“Support from the Department of Energy will enable my group to pursue the ambitious quantum chemistry development required to simulate the dynamics of transition metal-based molecular computing paradigms and multi-excitonic processes in a purely ab initio manner,” Shee said in the release.

Geng is developing next-generation AI for real-time digital twins for scientific systems. Geng and his team will make microchips that function as trainable electronic dynamical systems computing through natural, continuous evolution rather than digital instructions, according to the university.

Chiang’s work at UH addresses the DOE’s Quantum Information Science priority. Chiang leads a team that develops and applies “plasmonic-enhanced near-field optical techniques” to investigate fundamental light-matter interactions at the quantum limit before applying them to emerging technologies. In addition, the team will use AI to help with data acquisition and will utilize STEM workforce development.

Dr. Joshua Burby, an assistant professor in the Department of Physics at the University of Texas at Austin, and Junyeong Ahn, who is part of the University’s Texas Quantum Institute, also received early career awards for their work in superconducting and fusion technologies. See the full list of recipients from around the country here.

“The energy and creativity of early-career scientists is crucial for propelling scientific discovery forward. The Department of Energy is committed to nurturing this talent through programs like the Early Career Research Program,” Darío Gil, DOE under secretary for science, added in a release. “These awards provide essential resources and opportunities for collaboration, enabling these researchers to explore novel concepts and accelerate the development of solutions for our nation’s energy and scientific landscape.”

The DOE has also doled out funding to Houston researchers and companies in recent months through its Genesis Mission and geothermal initiatives.

Researchers from Rice, UH and Halliburton were named in July among the nearly 300 projects selected under the Trump administration's Genesis Mission, which aims to address some of the largest science and technology challenges in the country

In September, three Houston companies also received more than $45 million in funding from the DOE's Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation initiative to advance geothermal technologies and field tests. The projects were among 21 selected from around the country to receive a total of $99 million. Read more here.
