Conroe-based hardtech startup FluxWorks has closed a $5 million seed round.

The funding was led by Austin-based Scout Ventures, which invests in early-stage startups working to solve national security challenges.

Michigan Capital Network also contributed to the round from its MCN Venture Fund V. The fund is one of 18 selected by the Department of Defense and Small Business Administration to participate in the Small Business Investment Company Critical Technologies Initiative, which will invest $4 billion into over 1,700 portfolio companies.

FluxWorks reports that it will use the funding to drive the commercialization of its flagship Celestial Gear technology.

"At Scout, we invest in 'frontier tech' that is essential to national interest. FluxWorks is doing exactly that by solving critical hardware bottlenecks with its flagship Celestial Gear technology ... This is about more than just gears; it’s about strengthening our industrial infrastructure," Scout Ventures shared in a LinkedIn post.

Fluxworks specializes in making contactless magnetic gears for use in extreme conditions, which can enhance in-space manufacturing. Its contactless design leads to less wear, debris and maintenance. Its technology is particularly suited for space applications because it does not require lubricants, which can be difficult to control at harsh temperatures and in microgravity.

The company received a grant from the Texas Space Commission last year and was one of two startups to receive the Technology in Space Prize, funded by Boeing and the Center for the Advancement of Science in Space (CASIS), in 2024. It also landed $1.2 million through the National Science Foundation's SBIR Phase II grant this fall.

Fluxworks was founded in College Station by CEO Bryton Praslicka in 2021. Praslicka moved the company to Conroe 2024.

Houston small biz organization expands strategic partnerships

more support

In alliance with their mission of supporting Houston small businesses the Small Business Administration Houston District Office has expanded its partnerships.

The Houston SBA has joined forces with various organizations across a 32-county footprint.

“Small businesses represent an important and valuable resource in our community and our robust SBE program shows just how much small businesses can contribute when given the chance, and what it can mean in terms of overall economic benefits to the economy," Sabeeta Bidasie-Singh, director of business equity for Port Houston, says in a news release. “Collaborating with partners like the SBA is a key part of our success in supporting the small business ecosystem.”

Organizations signed a Strategic Alliance Memoranda to collaborate to further the interests of small businesses. In 2023, strategic partnerships included Greater Houston Partnership, Indo-American Chamber of Commerce, Houston Hispanic Chamber of Commerce, Fort Bend County Economic Opportunity & Development, Port Houston, Harris County Department of Economic Equity and Opportunity, Harris County Department of Education, Ion, Impact HUB, and Vision Galveston.

“Every small business deserves the chance to prosper,” Tim Jeffcoat, district director for Houston SBA, says in a news release. “SBA Houston strategically chose to partner with these important organizations so that small businesses of all kinds, everywhere in the 32-county Houston district, will benefit.”

SBA works with small business owners to assist with resources and support business growth and development. SBA also assists with businesses that need recovery from a declared disaster. SBA field offices and partnerships with public and private organizations like Ion help the city’s entrepreneurs.

“As a premiere destination for entrepreneurs to make their ideas a reality, we’re delighted to collaborate with the Small Business Administration to help Houstonians start, maintain and grow businesses,” Deanea LeFlore, senior director of Strategic Alliances at Ion, says in a news release. “We're excited to expand our relationships with the SBA to empower Houston’s small business community to scale their businesses, contributing to greater economic growth in the city.”

Expert: The major impact women of Texas have on the state's small biz exports

guest column

Everything is bigger in Texas, including its small business ecosystem. There are over three million small businesses in the state, which represent 99.8 percent of all Texas businesses. However, according to the latest official U.S. Census Bureau data on small business exporters (2020), only 35,124 Texas-based companies exported goods abroad.

During my time in the Administration, I have had the opportunity to visit Texas on several occasions, including trips to Houston, San Antonio, and El Paso. Like most everything in Texas, the entrepreneurial ecosystem is sizable and a rich source of opportunity and ideas. But with over a thousand miles of shared border with Mexico, and considerable trade infrastructure like the Port of Houston, you can’t tell me that just 1 percent of Texas small businesses are exporting their products or services. This data, which mirrors the published trend for small business exporters nationwide, seemed severely undercounted. So, we endeavored to dig into what was going on.

As a result, the Office of International Trade (OIT) commissioned a study to determine the total addressable market (TAM) of small business exporters. The research dug deep into available public data and private surveys, which better accounted for smaller shipment values and growth in service exports. Among the key findings from the study is new data that places the actual number of exporting small businesses at 1.3 million – an almost fivefold increase over the estimates previously published by the Federal Government. Interestingly, minority, women-owned firms were found to over-index in selling abroad. The research also revealed a high concentration of certain tradeable sectors ranging from consumer, industrial, and other manufactured goods to services businesses in software, architectural, and engineering sectors. Ultimately, the study estimated the potential market size, or total addressable market, at over 2.6 million small businesses.

With the proliferation of digital commerce tools and with over 95 percent of the world’s consumers living outside the United States, international sales represent a rich growth opportunity for small businesses. Indeed, businesses that export are more resilient, expand faster, and create higher paying jobs for Americans.

My colleague, District Director Tim Jeffcoat agrees. With his finger on the local pulse of the Houston-area economic market, he knows that exporting can be both an enormous growth opportunity, but at the same time filled with a daunting set of challenges to navigate. In his

Houston area network alone, they have over 200 advisors, mentors, and counselors that can guide you to develop a robust exporting plan, connect you with capital to fund your overseas expansion, and can even help you pursue a competitive grant to kick-start international sales.

This is exactly the case for Pat Hartmann, founder of Hartmann’s Inc., an Abilene, TX-based woman-owned small business. As a manufacturer of high-quality parts from state-of-the-art metal fabrication and welding departments, Hartmann has leveraged international sales to grow her company over three generations. In her words: “exporting has allowed us to become competitive in multiple markets throughout the entire world. It has diversified our knowledge base allowing us to work in manufacturing situations that span multiple types of standards including European and Japanese. Exporting now makes up 20 percent of our sales.”

As a result, Regional Administrator Ted James and I are among the many Administration officials who are pleased to recognize Pat Hartmann of Hartmann’s Inc. as the 2023 South Central Regional Exporter of the Year. She has established herself as a personal and professional role model due to their expansion and contributions to the community. We are confident that small businesses like these, as well as those identified in our Total Addressable Market study, can start and continue to leverage SBA resources to scale their business and access international opportunities, just as Hartmann did.

Pat Hartmann is one of the more than 11 million female founders the SBA is recognizing during Women’s History Month this March. While the post-pandemic recovery has complicated the economic landscape, we continue to better understand the important role women-owned small businesses play in our entrepreneurial ecosystem. They continue to contribute substantially to the national economy, showcasing innovative solutions and trailblazing techniques to lead the way forward.

If you are a current or future entrepreneur looking for assistance in how to get started or grow internationally, contact the SBA’s Office of International Trade or our network of 68 district offices which offer access to counseling, access to contracts, and access to capital.

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.

SBA launches Virtual Business Recovery Center to assist Texas loan applicants after winter storm

funds for small biz

Texas small businesses impacted by Winter Storm Uri are now eligible for up to $2 million in low-interest loans from the U.S. Small Business Administration as a result of President Joe Biden's major disaster declaration last week.

"Getting our businesses and communities up and running after a disaster is our highest priority at SBA," says SBA's acting Administrator Tami Perriello.

According to a release from the SBA, businesses in 77 counties are covered under the declaration for damages incurred during the storm, starting February 11. Loans can be used to repair or replace damaged or destroyed real estate, machinery and equipment, inventory and other business assets. The funds can also be used to make improvements that will protect, prevent, or minimize damage from any future freezes.

Interest rates for businesses start at 3 percent. Loans to private nonprofit organizations will start at 2 percent and homeowners and renters will incur interest at 1.25. All loans are set with 30 years terms.

Loan amounts and terms are determined by the SBA based on each applicant's financial condition.

The SBA will also launch a Virtual Business Recovery Center on February 23 — similar to the Women Business Centers it launched across the country in 2020, but all virtual due to COVID-related health concerns.

Applicants can call or email the virtual center to receive personalized assistance in their online loan applications at 800-659-2955 or FOCWAssistance@sba.gov, from 8 a.m. to 8 p.m.

Assistance will also be provided to help homeowners and renters through a similar Virtual Disaster Loan Outreach Center, which applicants can reach through the same number and email address.

Homeowners are eligible for up to $200,000 to repair or replace damaged or destroyed real estate.Renters and homeowners are also eligible for up to $40,000 for destroyed personal property.

To get started, applicants must contact FEMA at disasterassistance.gov. To download an application visit disasterloanassistance.sba.gov. Individuals who are deaf or hard‑of‑hearing can call 800-877-8339.

2 Houston startups win national technology award from SBA

winner, winner

A couple of Houston startups have something to celebrate. The United States Small Business Administration announced the winners of its Tibbetts Award, which honors small businesses that are at the forefront of technology, and two Houston startups have made the list.

Re:3D, a sustainable 3D printer company, and Raptamer Discovery Group, a biotech company that's focused on therapeutic solutions, were Houston's two representatives in the Tibbetts Award, named after Roland Tibbetts, the founder of the SBIR Program.

"I am incredibly proud that Houston's technology ecosystem cultivates innovative businesses such as re:3D and Raptamer. It is with great honor and privilege that we recognize their accomplishments, and continue to support their efforts," says Tim Jeffcoat, district director of the SBA Houston District Office, in a press release.

Re:3D, which was founded in 2013 by NASA contractors Samantha Snabes and Matthew Fiedler to tackle to challenge of larger scale 3D printing, is no stranger to awards. The company's printer, the GigaBot 3D, recently was recognized as the Company of the Year for 2020 by the Consumer Technology Association. Re:3D also recently completed The Ion Smart and Resilient Cities Accelerator this year, which has really set the 20-person team with offices in Clear Lake and Puerto Rico up for new opportunities in sustainability.

"We're keen to start to explore strategic pilots and partnerships with groups thinking about close-loop economies and sustainable manufacturing," Snabes recently told InnovationMap on the Houston Innovators Podcast.

Raptamer's unique technology is making moves in the biotech industry. The company has created a process that makes high-quality DNA Molecules, called Raptamers™, that can target small molecules, proteins, and whole cells to be used as therapeutic, diagnostic, or research agents. Raptamer is in the portfolio of Houston-based Fannin Innovation Studio, which also won a Tibbetts Award that Fannin Innovation Studio in 2016.

"We are excited by the research and clinical utility of the Raptamer technology, and its broad application across therapeutics and diagnostics including biomarker discovery in several diseases, for which we currently have an SBIR grant," says Dr. Atul Varadhachary, managing partner at Fannin Innovation Studio.

This year, 38 companies were honored online with Tibbetts Awards. Since its inception in 1982, the awards have recognized over 170,000 honorees, according to the release, with over $50 billion in funding to small businesses through the 11 participating federal agencies.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

So, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”
