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.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
