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.

A View From HETI

Texas falls among the middle of the pack when it comes to EV adoption, according to a new report. Photo via Unsplash

Even though Texas is home to Tesla, a major manufacturer of electric vehicles, motorists in the Lone Star State aren’t in the fast lane when it comes to getting behind the wheel of an EV.

U.S. Department of Energy data compiled by Visual Capitalist shows Texas has 689.9 EV registrations per 100,000 people, putting it in 20th place for EV adoption among the 50 states and the District of Columbia. A report released in 2023 by the University of Houston and Texas Southern University found that a little over 5 percent of Texans drove EVs.

California leads all states for EV adoption, with 3,025.6 registrations per 100,000 people, according to Visual Capitalist. In second place is Washington, with an EV adoption rate of 1,805.4 per 100,000.

A recent survey by AAA revealed lingering reluctance among Americans to drive all-electric vehicles.

In the survey, just 16 percent of U.S. adults reported being “very likely” or “likely” to buy an all-electric vehicle as their next car. That’s the lowest level of interest in EVs recorded by AAA since 1999. The share of consumers indicating they’d be “very unlikely” or “unlikely” to buy an EV rose to 63 percent, the highest level since 2022.

Factors cited by EV critics included:

  • High cost to repair batteries (62 percent).
  • High purchase price (59 percent).
  • Ineffective transportation for long-distance travel (57 percent).
  • Lack of convenient public charging stations (56 percent).
  • Fear of battery running out of power while driving (55 percent).

“Since AAA began tracking consumer interest in fully electric vehicles, we’ve observed fluctuations in enthusiasm,” said Doug Shupe, corporate communications manager for AAA Texas. “While automakers continue investing in electrification and expanding EV offerings, many drivers still express hesitation — often tied to concerns about cost, range, and charging infrastructure.”
