Houston had a strong showing at this week's SXSW Pitch showcase in Austin, with two local startups claiming top prizes in their respective categories.

Little Place Labs, a Houston space data startup, won the Security, GovTech & Space competition. 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.

As one of SWSX's marquee events, held March 8-10, the pitch competition featured 45 finalists, selected from 589 applicants, in nine categories.

"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 echoed that sentiment with a post on LinkedIn celebrating the win.

"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,” the post read. "Today, that mission feels even stronger."

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.

Two other Houston companies were selected as finalists:

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.

Rice University professor earns $550k NSF award for wearable imaging tech

science supported

Another Houston scientist has won one of the highly competitive National Science Foundation (NSF) CAREER Awards.

Lei Li, an assistant professor of electrical and computer engineering at Rice University, has received a $550,000, five-year grant to develop wearable, hospital-grade medical imaging technology capable of visualizing deep tissue function in real-time, according to the NSF. The CAREER grants are given to "early career faculty members who demonstrate the potential to serve as academic models and leaders in research and education."

“This is about giving people access to powerful diagnostic tools that were once confined to hospitals,” Li said in a news release from Rice. “If we can make imaging affordable, wearable and continuous, we can catch disease earlier and treat it more effectively.”

Li’s research focuses on photoacoustic imaging, which merges light and sound to produce high-resolution images of structures deep inside the body. It relies on pulses of laser light that are absorbed by tissue, leading to a rapid temperature rise. During this process, the heat causes the tissue to expand by a fraction, generating ultrasound waves that travel back to the surface and are detected and converted into an image. The process is known to yield more detailed images without dyes or contrast agents used in some traditional ultrasounds.

However, current photoacoustic systems tend to use a variety of sensors, making them bulky, expensive and impractical. Li and his team are taking a different approach.

Instead of using hundreds of separate sensors, Li and his researchers are developing a method that allows a single sensor to capture the same information via a specially designed encoder. The encoder assigns a unique spatiotemporal signature to each incoming sound wave. A reconstruction algorithm then interprets and decodes the signals.

These advances have the potential to lower the size, cost and power consumption of imaging systems. The researchers believe the device could be used in telemedicine, remote diagnostics and real-time disease monitoring. Li’s lab will also collaborate with clinicians to explore how the miniaturized technology could help monitor cancer treatment and other conditions.

“Reducing the number of detection channels from hundreds to one could shrink these devices from bench-top systems into compact, energy-efficient wearables,” Li said in the release. “That opens the door to continuous health monitoring in daily life—not just in hospitals.”

Amanda Marciel, the William Marsh Rice Trustee Chair of chemical and biomolecular engineering and an assistant professor at Rice, received an NSF CAREER Award last year. Read more here.

Houston Spaceport launches $12M expansion for leading space tech co.

to the moon

Houston will get one step closer to the moon, as the Houston Spaceport at Ellington Airport (EFD) has announced an expansion of the lease for Intuitive Machines, the Houston space tech leader dedicated to furthering lunar exploration.

On July 15, the City of Houston announced passage of Amendment 1, which would add three acres of commercial space for Intuitive Machines at the spaceport and a $12 million infrastructure expansion. Approved by the city council and Mayor John Whitmire, the expansion will include new production, testing and support facilities. The amendment extends the current lease for Intuitive Machines from 20 years to 25 years.

"I want to shout out to Intuitive Machines about everything they’re doing at the Houston Spaceport. It’s exciting to see them expand. We’re starting to reach a critical mass out there — more and more aerospace companies want to be at the Spaceport because that’s where innovation is happening,” said Fred Flinkinger, who represents District E on the Houston City Council. “It’s a great sign of momentum, and we’re proud to have them here in Houston."

Intuitive Machines was the first commercial tenant for the Houston Spaceport when it moved into the facility in August 2016. Founded by Stephen Altemus, Kam Ghaffarian, and Tim Crain in 2013, the company holds three contracts with the National Aeronautics and Space Administration (NASA) to deliver payloads to the lunar surface. In 2023, the company opened its doors in Houston with a 105,572-square-foot Lunar Production and Operations Center that contains research and development labs, clean rooms, mission control centers, and a spacecraft assembly floor.

Intuitive Machines landed Odysseus on the moon in February 2024, the first privately owned soft lunar landing ever and the first soft landing since 1972.

The Houston Spaceport is owned and operated by the City of Houston and Houston Airports, who have an eye of keeping the city a prime name in space exploration. As "Houston" was the first word spoken on the moon when Apollo 11 landed in 1969, lunar exploration in particular has a soft place in the heart of the metropolis formerly known as Space City.

“This agreement reinforces Houston’s leadership in space innovation,” said Jim Szczesniak, director of aviation for Houston Airports. “We’re building infrastructure and supporting the next era of lunar and deep space exploration, right here at Houston Spaceport. This partnership represents the forward-thinking development that fuels job creation and drives long-term economic growth.”
