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.

A handful of Houstonians have been named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

Kip Daujotas is an investment associate at Aramco Ventures, a $7.5 billion venture capital arm of the world's largest energy company. Houston is the Americas headquarters for Saudi Aramco. Since its inception in 2012, Aramco Ventures has invested in more than 100 tech startups. Daujotas joined the team over two years ago after studying for an MBA at Yale University. He led Aramco’s first direct air capture (DAC) investment — in Los Alamos, New Mexico-based Spiritus.

Also representing the corporate side of the industry, Wenting Gao immigrated from Beijing to obtain an economics degree from Harvard University, then got a job at consulting giant McKinsey, where she recently became the firm’s youngest partner. Gao works on bringing sustainability strategies to energy and materials companies as well as investors. Her areas of expertise include battery materials, waste, biofuels, and low-carbon products.

Last but not least, Houston entrepreneur Rawand Rasheed is co-founder and CEO of Houston-based Helix Earth. He co-founded the startup after earning a doctoral degree from Rice University and co-inventing Helix’s core technology while at NASA, first as a graduate research fellow and then as an engineer. The core technology, a space capsule air filtration system, has been applied to retrofitting HVAC systems for commercial buildings.

Each year, Forbes 30 Under 30 recognizes 600 honorees in 20 categories. The 2025 honorees were selected from more than 10,000 nominees by Forbes staff and a panel of independent judges based on factors such as funding, revenue, social impact, scale, inventiveness, and potential.

Specifically, the Energy & Green Tech category recognizes young entrepreneurs driving innovation that’s aimed at creating a cleaner, greener future.

“Gen Z is one of the fastest-growing groups of entrepreneurs and creators, who are reshaping the way the world conducts business, and our Under 30 class of 2025 proves that you can never begin your career journey too early,” says Alexandra York, editor of Forbes Under 30. “With the expansion across AI, technology, social media, and other industries, the honorees on this year’s list are pushing the boundaries and building their brands beyond traditional scopes.”

After working for years in the downstream energy industry where safety and efficiency were top priorities, Dianna Liu thought there was a way technology could make a huge difference.

Despite loving her company and her job, she took a leap of faith to start a robotics company to create technology to more safely and efficiently monitor corrosion in pipelines. ARIX Technologies has developed software and hardware solutions for its customers with pipelines in downstream and beyond.

"Overall, this industry is an industry that really harps on doing things safely, doing things well, and having all the data to make really informed decisions," Liu says on the Houston Innovators Podcast. "Because these are huge companies with huge problems, it takes a lot of time to set up the right systems, adopt new things, and make changes." Continue reading.

In a guest column, Nada Ahmed, founding partner at Houston-based Energy Tech Nexus, draws a uniquely Houston comparison between the health tech innovation sector and that of the climate tech world.

"Over the past several decades, climate tech has faced numerous challenges, ranging from inconsistent public support to a lack of funding from cautious investors. While grassroots organizations and climate innovators have made notable efforts to address urgent environmental issues, we have yet to see large-scale, lasting impact," she writes.

"A common tendency is to compare climate tech to the rapid advancements made in digital and software technology, but perhaps a more appropriate parallel is the health tech sector, which encountered many of the same struggles in its early days," she continues. Continue reading.

health tech

A team from the NSF University of Houston Building Reliable Advances and Innovation in Neurotechnology (UH BRAIN) Center and TIRR Memorial Hermann has introduced the MyoStep soft exoskeleton for children with cerebral palsy, according to a news release from UH.

The soft skeleton aims to address motor impairments caused by cerebral palsy that impact children’s ability to participate in physical activities, self-care and academics.

“The MyoStep project represents a significant advancement in the field of pediatric mobility aids, particularly for children with cerebral palsy,” Jose Luis Contreras-Vidal, director of UH BRAIN and the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering, said in a news release.

The next-generation lightweight, soft exoskeleton was funded by the IEEE Electron Devices Society (EDS) Award.

The MyoStep is made to be lightweight and discreetly fit under clothes. It includes a wireless sensor network embedded inside the smart and flexible fabrics that is the backbone of the suit and collects and sends real-time data about the user’s movements It also includes safety features with temperature monitoring and emergency shut-off mechanisms.

“By integrating cutting-edge technologies such as artificial muscles, smart fabrics, and a comprehensive sensor network, MyoStep offers a promising solution to the challenges faced by existing exoskeletons,” Contreras-Vidal said in a news release.

Cerebral palsy is a neurological disorder that impacts motor skills. It occurs in one to four out of every 1,000 births worldwide.

“What makes the MyoStep project so compelling is that it’s not just about the technology: it’s about restoring confidence, function, and hope,” Dr. Gerard Francisco, a clinical partner on the technology, The Wulfe Family Chair of Physical Medicine and Rehabilitation at UTHealth Houston and medical officer at TIRR Memorial Hermann, said in a news release. “This kind of innovation has the potential to dramatically improve quality of life, helping children move through the world with greater ease and dignity.”
