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.

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.

Houston poised to add 30,900 new jobs in 2026, forecast says

jobs forecast

Buoyed by the growing health care sector, the Houston metro area will add 30,900 jobs in 2026, according to a new forecast from the Greater Houston Partnership.

The report predicts the Houston area’s health care sector will tack on 14,000 jobs next year, which would make it the No. 1 industry for local job growth. The 14,000 health care jobs would represent 45 percent of the projected 30,900 new jobs. In the job-creation column, the health care industry is followed by:

  • Construction: addition of 6,100 jobs in 2026
  • Public education: Addition of 5,800 jobs
  • Public administration: Addition of 5,000 jobs

At the opposite end of the regional workforce, the administrative support services sector is expected to lose 7,500 jobs in 2026, preceded by:

  • Manufacturing: Loss of 3,400 jobs
  • Oil-and-gas extraction: Loss of 3,200 jobs
  • Retail: Loss of 1,800 jobs

“While current employment growth has moderated, the outlook remains robust and Houston’s broader economic foundation remains strong,” GHP president and CEO Steve Kean said in the report.

“Global companies are choosing to invest in Houston — Eli Lilly, Foxconn, Inventec, and others — because they believe in our workforce and our long-term trajectory,” Kean added. “These commitments reinforce that Houston is a place where companies can scale and where our economy continues to demonstrate its resilience as a major engine for growth and opportunity. These commitments and current prospects we are working on give us confidence in the future growth of our economy.”

The Greater Houston Partnership says that while the 30,900-job forecast falls short of the region’s recent average of roughly 50,000 new jobs per year, it’s “broadly in line with the muted national outlook” for employment gains anticipated in 2026.

“Even so, Houston’s young, skilled workforce and strong pipeline of major new projects should help offset energy sector pressures and keep regional growth on pace with the nation,” the report adds.

The report says that even though the health care sector faces rising insurance costs, which might cause some people to delay or skip medical appointments, and federal changes in Medicare and Medicaid, strong demographic trends in the region will ensure health care remains “a key pillar of Houston’s economy.”

As for the local oil-and-gas extraction industry, the report says fluctuations and uncertainty in the global oil-and-gas market will weigh on the Houston sector in 2026. Furthermore, oil-and-gas layoffs partly “reflect a longer-term trend as companies in the sector move toward greater efficiency using fewer workers to produce similar volumes,” according to the report.

Construction underway on first-of-its-kind 3D-printed community in Houston

Building a Sustainable Future

Houston is putting itself front-and-center to help make sustainable, affordable housing a reality for 80 homeowners in an innovative scalable housing community. Developer Cole Klein Builders has partnered with HiveASMBLD to pioneer what’s touted as the world’s first large-scale, one-of-a-kind, affordable housing development using 3D printing technology — merging robotics, design, and sustainability.

Located across from Sterling Aviation High School, near Hobby Airport, Zuri Gardens will offer 80 two-bedroom, two-bathroom homes of approximately 1,360 square feet, situated in a park-like setting that includes walking trails and a community green space.

Homes in Zuri Gardens will hit the market in early summer of 2026. Final pricing has yet to be determined, but Cole Klein Builders expects it to be in the mid-to-high 200s.

Interestingly, none of the homes will offer garages or driveways, which the developer says will provide a cost savings of $25,000-$40,000 per home. Instead of parking for individual units, 140 parking spaces will be provided.

Each two-story home is comprised of a ground floor printed by HiveASMBLD, using a proprietary low-carbon cement alternative by Eco Material Technologies that promises to enhance strength and reduce CO2 emissions. The hybrid homes will have a second floor built using engineered wood building products by LP Building Solutions. Overall, the homes are designed to be flood, fire, and possibly even tornado-proof.

The "Zuri" in Zuri Gardens is the Swahili word for “beautiful,” a choice that is fitting considering that the parks department will be introducing a five acre park to the project — with 3D-printed pavilions and benches — plus, a three-acre farm is located right across the street. The Garver Heights area is classified as a food desert, which means that access to fresh food is limited. Residents will have access to the farm’s fresh produce, plus opportunities to participate in gardening and nutrition workshops.

Cole Klein Builders created Zuri Gardens in partnership with the Houston Housing Community Development Department, who provided infrastructure reimbursements for the roads, sewer lines, and water lines. In return, CKB agreed to push the purchase prices for the homes as low as possible.

Zuri Gardens also received $1.8 million dollars from the Uptown Tourism Bond, 34 percent of which must be used with minority-owned small businesses. Qualified buyers must fit a certain area of median income according to HUD guidelines, and homes must be owner-occupied at all times. Zuri Gardens already has an 800-person waitlist.

“They’re trying to bridge that gap to make sure there is a community for the homebuyers who need it — educators, law enforcement, civil workers, etc.,” Cole Klein Builders’ co-principal Vanessa Cole says. “You have to go through a certification process with the housing department to make sure that your income is in alignment for this community. It has been great, and everyone has been really receptive.”

Cole has also brought insurance underwriters to visit the site and to help drive premiums below regular rates for Houston homeowners, as claim risks for one of the 3D homes are extremely low.

Tim Lankau, principal at HiveASMBLD, notes that the 3D hybrid design allows for a more traditional appearance, while having the benefits of a concrete structure: “That’s where the floodwaters would go, that’s where you can hide when there’s a tornado, and that’s where termites would eat. So you get the advantages of it while having a traditionally-framed second floor.”

It’s important to note that Zuri Gardens is not located in a flood prone area, nor did it flood during Hurricane Harvey — being flood-proof is merely a perk of a cement house. The concrete that Eco Material Technologies developed is impervious. The walls are printed into hollow forms, which house rebar, plumbing, and accessible conduits for things like electrical lines and smart house features. Those walls are then filled with a foamcrete product that expands to form a “monolithic concrete wall.”

David McNitt, of Eco Material Technologies, explains that his proprietary concrete is made of PCV, and contains zero Portland cement. Instead, McNitt’s cement is made from coal ash and is 99 percent green (there are a few chemicals added to the ash). Regardless, it’s made from 100 percent waste products.

“This is a product that has really been landfilled before,” says McNitt. “It’s coal ash, and it’ll set within 8-10 minutes. It’s all monolithic, and one continuous pour — it’s literally all one piece.”

Eco Material Technologies’ concrete product is impressively durable. A traditional cinderblock wall will crush at around 800 psi, while this material crushes at about 8,000 psi.

“It’s ten times stronger than a cinderblock wall that can withstand hurricanes,” claims McNitt. “I don’t think you’d even notice a hurricane. It’ll be really quiet inside, too — so you won’t get interrupted during your hurricane party. It’s way over-engineered, it really is.”

The second story is built using weatherproof and eco-friendly products by LP Building Solutions. Their treated, engineered wood products come with a 50 year warranty, and their radiant barrier roof decking product blocks 97% of UV rays, and keeps attic temperatures 30° cooler than traditional building materials. These materials, combined with the concrete first floor, will keep heating and cooling costs low — something the folks at HiveASMBLD refer to as “thermal mass performance.”

UH receives $2.6M gift to support opioid addiction research and treatment

drug research

The estate of Dr. William A. Gibson has granted the University of Houston a $2.6 million gift to support and expand its opioid addiction research, including the development of a fentanyl vaccine that could block the drug's ability to enter the brain.

The gift builds upon a previous donation from the Gibson estate that honored the scientist’s late son Michael, who died from drug addiction in 2019. The original donation established the Michael C. Gibson Addiction Research Program in UH's department of psychology. The latest donation will establish the Michael Conner Gibson Endowed Professorship in Psychology and the Michael Conner Gibson Research Endowment in the College of Liberal Arts and Social Sciences.

“This incredibly generous gift will accelerate UH’s addiction research program and advance new approaches to treatment,” Daniel O’Connor, dean of the College of Liberal Arts and Social Sciences, said in a news release.

The Michael C. Gibson Addiction Research Program is led by UH professor of psychology Therese Kosten and Colin Haile, a founding member of the UH Drug Discovery Institute. Currently, the program produces high-profile drug research, including the fentanyl vaccine.

According to UH, the vaccine can eliminate the drug’s “high” and could have major implications for the nation’s opioid epidemic, as research reveals Opioid Use Disorder (OUD) is treatable.

The endowed professorship is combined with a one-to-one match from the Aspire Fund Challenge, a $50 million grant program established in 2019 by an anonymous donor. UH says the program has helped the university increase its number of endowed chairs and professorships, including this new position in the department of psychology.

“Our future discoveries will forever honor the memory of Michael Conner Gibson and the Gibson family,” O’Connor added in the release. “And I expect that the work supported by these endowments will eventually save many thousands of lives.”
