Three Houston startups were granted awards from NASA this month to develop new technologies for the space agency.

The companies are among nearly 300 recipients that received a total agency investment of $44.85 million through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Phase I grant programs, according to NASA.

Each selected company will receive $150,000 and, based on their progress, will be eligible to submit proposals for up to $850,000 in Phase II funding to develop prototypes.

The SBIR program lasts for six months and contracts small businesses. The Houston NASA 2025 SBIR awardees include:

Solidec Inc.

  • Principal investigator: Yang Xia
  • Proposal: Highly reliable and energy-efficient electrosynthesis of high-purity hydrogen peroxide from air and water in a nanobubble facilitated porous solid electrolyte reactor

Rarefied Studios LLC

  • Principal investigator: Kyle Higdon
  • Proposal: Plume impingement module for autonomous proximity operations

The STTR program contracts small businesses in partnership with a research institution and lasts for 13 months. The Houston NASA 2025 STTR awardees include:

Affekta LLC

  • Principal investigator: Hedinn Steingrimsson
  • Proposal: Verifiable success in handling unknown unknowns in space habitat simulations and a cyber-physical system

Solidec and Affekta have ties to Rice University.

Solidec extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions. It was co-founded by Rice professor Haotian Wang and and was an Innovation Fellow at Rice’s Liu Idea Lab for Innovation and Entrepreneurship. It was previouslt selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

Affekta, an AI course, AI assistance and e-learning platform, was a part of Rice's OwlSpark in 2023.

Houston 3D printing company lands funding from NASA

funds granted

Houston-based re:3D Inc was recently one of 12 innovative companies from around the country to be granted Phase II awards from a NASA small business initiative, the space giant announced earlier this week.

The grants of up to $850,000 are awarded to early-stage, high-risk technology concepts that could be commercialized for use in space and on Earth as part of NASA's SBIR Ignite pilot, which is part of NASA’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs.

The program was launched to support emerging companies "whose end customers may not be only NASA but are still creating technology that NASA cares about,” Jason L. Kessler, program executive for the NASA SBIR/STTR program, says in a previous statement. And it aims to attract companies that have not yet worked with NASA.

The concepts from the cohort have applications in climate resilience, low-cost solar cells and active debris remediation. Re:3D Inc.'s project looks to develop a recycling system that uses a 3D printer to turn thermoplastic waste generated in orbit into functional and useful objects, according to the project's proposal.

SBIR Ignite made its inaugural Phase I awards in 2022, granting about $2 million in total to the 12 companies, including re:3D Inc. The Phase II grants are intended to help the companies create their prototypes.

“We are proud that all 12 of the small businesses are continuing with our program and persevering through the tough realities of early-stage research and development,” Kessler said in a statement made this month. "These awards foster a unique range of technologies that we hope will have positive impacts on the lives of everyday Americans in the future."

Re3D Inc. is the only company from Texas in the cohort. The other 11 awarded companies and their projects include:

  • Ampaire Inc.: High Efficiency Powertrain for Hybrid Aircraft
  • Canopy Aerospace Inc.: Reusable Heatshields through Additive Manufacturing
  • Cecilia Energy: Catalytic Conversion of Waste Plastic to Hydrogen
  • Crystal Sonic Inc.: Reducing Cost of Space Photovoltaics via Sound-Assisted Substrate Reuse
  • H3X Technologies Inc.: HPDM-30 – A 10 kW/kg Integrated Motor Drive for UAV and Aircraft Electric Propulsion
  • Outpost Technologies Corporation: Outpost Cargo Ferry: A Rapid Cargo Downmass Vehicle
  • Solestial, Inc.: Next Generation Silicon Based Solar Arrays for Space Stations and Other Permanent Space Infrastructure
  • StormImpact Inc.: Optimizing vegetation management to improve the resilience of the electrical power system to extreme weather
  • Terrafuse, Inc.: Wildfire Mitigation through Explainable Risk Predictions
  • Trans Astronautica Corporation: Mini Bee Capture Bag for Active Debris Remediation
  • Turion Space Corp.: Low-Cost CubeSat for Active Removal of Sizable Space Debris Utilizing a Mothership Architecture

Re:3D Inc. was founded in 2013 by NASA contractors Samantha Snabes and Matthew Fiedler and is based in Clear Lake. It's known for its GigaBot 3D printer, which uses recycled materials to create larger devices.

Since its founding it's been named to numerous accelerators and has earned national recognition, like the Tibbetts Award from the U.S. Small Business Administration, which honors small businesses that are at the forefront of technology. It was selected by the SBA to participate in its inaugural America’s Seed Fund Startup Expo last year.

They say it’s all in the timing. For CellChorus, it’s all in the TIMING. That’s Time-lapse Imaging Microscopy In Nanowell Grids. TIMING is a visual AI program that evaluates cell activation, killing and movement, which allows scientists to better understand how cells function.

The technology is important to the development of novel therapies in the realms of oncology, infectious diseases, and countless other disorders and diseases. By allowing scientists to observe those maladies at their roots, it will enable them to create, and ultimately deliver new medications and other therapies faster, at lower cost, and with a higher success rate.

CellChorus is a spinoff of the Single Cell Lab at the University of Houston. Part of UH’s Technology Bridge, CEO Daniel Meyer connected with co-founder and leader of Single Cell Lab, Navin Varadarajan, through co-founder Laurence Cooper.

“The company had been established, but there were limited operations,” recalls Meyer during a phone call with InnovationMap.

That was the fall of 2020. Now, the team has just announced a $2.3 million SBIR (Small Business Innovation Research) Fast-Track grant from the National Institute of General Medical Sciences.

“This funding will support development of a product offering that builds on the success of our early access laboratory,” Cooper said in a press release. “As the next frontier of cellular analysis, dynamic single-cell analysis will increase the impact that immunotherapies have in improving the lives of patients.”

Meyer is based in the Bay Area, but the rest of the team is in Houston. Meyer has a proven track record as an investor and early stage entrepreneur in life sciences companies, including work as COO of Genospace, which was acquired by HCA Healthcare.

Meyer says that what attracted him to CellChorus was a combination of a clear need for the technology and the fact that it was “very well validated.“

“Developers of immunotherapies need better functional data earlier so that they can develop and deliver better therapies,” he explains.

Another aspect of its appeal was the fact that more than 10 publications featured data from the TIMING platform.

“We’ve had both large and small biopharmas publish data,” says Meyer. “That’s important as well because it shows there’s applicability in both nonprofit and for-profit research.”

Though Meyer himself doesn’t currently live in Houston, he recognizes its importance to CellChorus. He says that it can be difficult for an early stage company to find appropriate lab space, so Technology Bridge was of exceptional importance for CellChorus. Since opening the lab a year and a half ago, Varadarajan and his team have been busy.

“Example projects we have completed include understanding mechanism of action for cell therapy products, selecting lead candidates for T cell engagers, identifying biomarkers of response to cell therapies, and quantifying potency and viability for cell therapy manufacturing technologies,” says Meyer.

And now, CellChorus is collaborating with leaders in the industry.

“These include top-25 biopharmaceutical companies and promising venture-backed biotechnology companies, as well as leading not-for-profit research institutions,” says Meyer in a press release. It’s clear that the TIMING is right for CellChorus to excel.

OpenStax, a tech initiative from Rice University that uploads free learning resources, has announced it will publish the 10th edition of an organic chemistry textbook by Cornell University professor emeritus John McMurry.

“This is a watershed moment for OpenStax and the open educational resources (OER) movement,” says Richard Baraniuk, founder and director of OpenStax, in a news release. “This publication will quickly provide a free, openly licensed, high-quality resource to hundreds of thousands of students in the U.S. taking organic chemistry, removing what can be a considerable cost and access barrier.”

Usually a big expense for organic chemistry students, McMurry, with the support of publisher Cengage, made the decision to offer the latest edition online as a tribute to his son, Peter McMurry, who died in 2019 after a long struggle with cystic fibrosis.

“If Peter were still alive, I have no doubt that he would want me to work on this 10th edition with a publisher that made the book free to students,” McMurry says in the release. “To make this possible, I am not receiving any payment for this book, and generous supporters have covered not only the production costs but have also made a donation of $500,000 to the Cystic Fibrosis Foundation to help find a cure for this terrible disease.”

Houston startup with life-saving innovation receives $2M grant

for the children

A $2 million federal grant will enable Houston-based PolyVascular to launch human trials of what it hails as the first polymer-based heart valve for children.

In conjunction with the grant, Dr. Will Clifton has joined the medical device company as chief operating officer. He will oversee the grant as principal investigator, and will manage the company's operations and R&D. Clifton is president and co-founder of Houston-based Enventure, a medical innovation incubator and education hub. He previously was senior director of medical affairs at Houston-based Procyrion, a clinical-stage medical device company.

PolyVascular's Phase II grant came from the Small Business Innovation Research (SBIR) program, which promotes technological projects.

The PolyVascular heart valve will help treat congenital heart disease affecting more than 1 million around the world. PolyVascular plans to launch clinical trials of the valve in children 5 and over within two years.

"Congenital heart disease remains the most common category of birth defect and a leading cause of childhood death in the developed world," reads a March 30 news release from PolyVascular, founded in 2014.

PolyVascular says the valve can be implanted without surgery, and can avoid the use of valve replacements from humans or animals. Those valve replacements are difficult to find and often don't last too long, leading to frequent follow-up surgeries.

"Our aim at PolyVascular is to transform the care of children with congenital heart disease by developing an entirely new generation of valves made of medical-grade polymer devoid of any biological tissue," Dr. Henri Justino, chief medical officer at PolyVascular, says in a release. "The valves in use so far for children have been made of biological tissue. Unfortunately, our immune systems target and destroy this biological tissue, sometimes rapidly, rendering the valve ineffective."

The SBIR grant isn't the only win for PolyVascular in recent years.

In 2019, the startup came away with several honors in the 2019 Texas A&M New Ventures Competition. It won the pitch competition (complete with a $5,000 cash award), and received the Biotex Investment Prize, Amerra Visualization Services Prize, and GOOSE Society Investment Prize.

Also in 2019, PolyVascular, a member of TMCx's 2017 medical device cohort, won in the medical device and health disparities and equity categories at the fifth annual Impact Pediatric Health pitch competition. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

Last year, MedTech Innovator, a nonprofit accelerator in the medical technology sector, announced PolyVascular was one of 50 companies chosen to participate in the organization's flagship four-month accelerator program.

"During these uncertain and challenging times, the need for health innovations — specifically those that promise to deliver long-term value to the health care system and patients — is more critical than ever," said Paul Grand, CEO of MedTech Innovator.

Another Houston startup, Vivante Health, also was picked for the MedTech Innovator program. Vivante is a digital health company that helps people address digestive health and wellness.

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
