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.

Even in 2021, women face discrimination in the workplace — whether it's running their own businesses or climbing the corporate ladder.

The five female finalists of the Female-Founded Business category for the InnovationMap Awards presented by Techwave were asked to share their challenges overcame as female founders. Here's what they had to say. Click here to register for the livestream.

Raising capital

Carolyn Rodz, founder of Hello Alice, says raising capital was her biggest challenge.

"We overcame it through insane networking and persistence," she continues. "Each round got easier as we proved that we knew how to grow this business and build a fiercely loyal owner community.

Katharine Forth, co-founder of Zibrio, agrees that raising early funding was her biggest challenge.

"To overcome it, I was very creative with the limited funds to generate the progress we created until we reached a threshold that was more comfortable for investors," she explains.

Being the only woman in the room

"This is a hurdle in and of itself, but it brings lots of other little behavioral hurdles too," says Kim Raath, CEO and co-founder of Topl. "Because men and women are socialized so differently, women often have to adapt to or accommodate for male-pattern behaviors."

Raath continues, saying how men tend to up-sell what they are doing, while women undersell. Additionally, she says, men are more likely to make statements while women suggest their ideas.

"It takes a lot of courage to fight for yourself and your ideas in a room full of men," Raath says. "You can't expect others to do it for you. Even further, those of us that are in the room have a duty to speak up, not just for our own sake, but for other voices that are still excluded. Being a woman in the tech space means learning how to accommodate, navigate, and hold your ground."

Being treated equally

For Samantha Snabes, co-founder of re:3D, her biggest challenge was being treated the same as her male co-founder.

"I've learned that I need to be more confident and to be proud of the differences in my leadership or communication style," she explains.

Being mistaken for the secretary

Shoshi Kaganovsky, founder of RingOn, says electronics is a very male dominated arena.

"Every time I approach a man — whether to interview him for a job or to partner up on another level — they think I'm the CEO's secretary," she says.

"When male investors talk to me they often times think I don't understand what I'm doing or that they need to dumb it down for me," continues Kaganovsky, who speaks five languages and has six degrees. "Second conversations are completely different usually."

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.

3 Houston innovators to know this week

who's who

Editor's note: In today's Monday roundup of Houston innovators to know as we start a new week, we introduce you to two forward-thinking 3D printing experts and a startup founder with fresh funds to tackle smart contracts in the industrial sector.

Houston-based Re:3D has no shortage of exciting business opportunities — from developing bigger and better 3D printers to hosting tours in their lab. But, one thing co-founder Samantha Snabes and community expert Charlotte Craff are proud of is their partnership with local organizations to create PPE for the People, a movement that helped create and provide PPE for workers in need.

"As the pandemic continued, the data was emerging that people of color in Black and Brown communities and underserved communities were at greater risk of critical illness from COVID-19," Craff says on the podcast. "We wanted to specifically target people of color who were working as Texas opened back up its doors." Read more.

Andrew Bruce, CEO of Data Gumbo

While the intersection of dropping oil prices earlier this year and a global pandemic provided its own set of challenges, one thing Andrew Bruce of Data Gumbo Corp. observed is that it was more important than ever for the energy industry to focus on their bottom line. And that's exactly what his technology allows to happen.

"The opportunity in all this is companies have got to cut expenses," Andrew Bruce, CEO and founder, tells InnovationMap. "What's happened to us is our sales have absolutely exploded — in a good way. We have a huge number of leads, and we have to be able to deliver on those leads."

Last month, Data Gumbo closed a $4 million series B funding round led by new investor L37, which has operations in the Bay Area and in Houston. The round also saw contribution from returning investors Equinor Ventures and Saudi Aramco Energy Venture. Read more.

Houston-based 3D printing company plans to change the world — one piece of trash at a time

Houston Innovators Podcast Episode 51

Aside from collecting their plastics throughout the week and dragging the bin to the curb, people aren't usually preoccupied with the recycling of materials. Houston-based Re:3D wants to change that.

The company was founded in 2013 by NASA contractors Samantha Snabes and Matthew Fiedler to tackle to challenge of larger scale 3D printing and give people the power to create things larger than a breadbox. The bootstrapped company has received grants and crowdfunding and grown to a 20-person team with a lab in Clear Lake.

Over the past seven years, Re:3D has evolved its technology, from enhancing its GigaBot 3D printers to print from recycled materials to creating larger devices, like a six-foot-tall 3D printer. A true testament to its growth, Re:3D was recognized as the Company of the Year for 2020 by the Consumer Technology Association.

The company has completed accelerators and pitch competitions and even recently finished The Ion Smart and Resilient Cities Accelerator this year, which has really set the team 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 says on this week's episode of the Houston Innovators Podcast.

Of course, like many startups, the emergence of COVID-19 affected Re:3D's sales cycle, but the pandemic did open a door to an opportunity to 3D print personal protection equipment. Through a partnership with Impact Hub Houston called PPE for the People, Charlotte Craff, who oversees community outreach, Re:3D started a months-long mission of printing PPE for at-risk workers who otherwise couldn't afford it.

"As the pandemic continued, the data was emerging that people of color in Black and Brown communities and underserved communities were at greater risk of critical illness from COVID-19," Craff says on the podcast. "We wanted to specifically target people of color who were working as Texas opened back up its doors."

PPE for the People is still hard at work — and even seeking donations and volunteers to help print and deliver the equipment — as the need to help keep these communities safe continues to be imperative.

Craff and Snabes share more about Re:3D — from its success on TripAdvisor as a top educational tour attraction in Houston to the future of 3D printing — on the episode. The duo even discusses an upcoming virtual tour of the Re:3D lab that's open to anyone on the Re:3D website.

You now have access to large-scale 3D printers, thanks to re:3D. The Houston company opened its community space in its factory located next to the NASA Johnson Space Center in southeast Houston.

The company makes an affordable and customizable 3D printer, called the Gigabot, and has clients across industries in over 50 countries. Recently, re:3D introduced sustainable options, including printing using plastic waste. The 7,000-square-foot space opened to the public on Saturday, April 13, with free tours and mingling.

This unveiled area allows for anyone in the community to learn about the 3D printing process, tour the facility, attend social events or workshops, or even buy a printer or some of the company's merchandise.

"re:3D couldn't be more thrilled to connect with our neighbors and share our desire to grow in Houston," says Co-Founder and Catalyst Samantha Snabes in a release. "In addition to offering regular classes and tours, we're seeking feedback on how we support innovation in Houston whether it be partnerships, cross-activations, meetups or other creative connections."

re:3D launched in 2013 — Snabes and her co-founder, Matthew Fiedler, were involved at NASA before founding the company. The company hasn't taken any investment money and has bootstrapped for the most part, receiving $1 million from WeWork's Creator Award, a $250,000 NSF Phase I Grant, and some other pitch competitions. The team also received $40,000 equity-free funding from Parallel18 and $40,000 from Startup Chile. Last year, the company, which has a presence in Austin and completed MassChallenge Texas. The company has raised over $300,000 in a couple Kickstarter campaigns over the years.

2 Houston startups win big at SXSW 2025 pitch competition

winner, winner

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.

A legacy of industrial technology excellence: UTSI International turns 40

Cheers to 40 Years

As UTSI International celebrates its 40th anniversary, president and CEO Shaun Six reflects on the company's history, achievements, and exciting future.

---

In March 1985, Dan Nagala and a few friends took a risk, leaving their full-time jobs to pursue their passion and start their own company.

They founded UTSI Internationalamidst groundbreaking advancements in Industrial Control Systems and SCADA technology, revolutionizing remote operations for critical infrastructure. From the start, UTSI has been at the forefront of OT innovation and integration — a legacy we proudly carry forward today.

The legacy of Dan Nagala

Dan Nagala’s 50-plus-year career is too vast to cover every accomplishment, but if you’ve ever heard the phrase “Houston, we have a problem” in a movie, those screens in the control room and the logic causing the “blinky lights” to alert the operators, you’ve seen some of his work. Dan and his team ultimately paved the way for field communications to detect and communicate leaks on pipelines and give operators in remote locations situational awareness, expanding their ability to safely monitor and control their operations.

This capability was requested early on in the first pipeline control rooms, leading to UTSI’s first check-in 1985 (which I proudly have framed on my bookshelf). The protocols to communicate and do advanced calculations — which many would be tempted to call AI today — for the purpose of monitoring and control, was created from this group of enthusiasts who open sourced it and allowed it to proliferate, leading to over 80 percent of all critical infrastructure in the world now utilizing a variant thereof.

Given the novelty of the technology and the experience of UTSI, having implemented control systems and automation for pipelines in over 22 countries, Dan was asked to collaborate with industry experts, creating the first API leak detection and control room management standards for the American Petroleum Institute. These would later become regulation under PHMSA, DoT, and TSA, placing UTSI as the go-to experts in compliance in addition to their traditional expertise.

UTSI has delivered for the world’s largest infrastructure owners in multiple critical infrastructure sectors, like mining, water/wastewater, oil and gas, green energy, transportation authorities, etc. We have also done AI and cybersecurity, in addition to SCADA and ICS work for the DoD and DoE.

Strength in partners

I joined UTSI in 2022 as vice president, working under Dan, with the goal of gradually stepping into leadership. In 2023, I became CEO, president, and majority shareholder. While no one can truly fill Dan’s shoes alone, we’ve focused on strengthening our team, partnerships, and capabilities to continue UTSI’s legacy of excellence.

One of our first strategic partnerships was with Tory Tech, a leading API-compliant Control Room Management tool. UTSI has worked as integrators with Tory Tech for years and Dan worked as a CRM compliance advisor for them in the U.S. while they were setting up their headquarters in Houston. In 2024 we made it an official partnership, becoming a preferred integrator and focusing our team on training and development in the MaCRoM (Master Control Room Management) tool.

We've also made significant investments in our OT cybersecurity capabilities, expanding our team and partnering with industry leaders like Dennis Parker, Derrik Oates, Nozomi Networks, Fortinet, and Schneider Electric. These strategic moves ensure we deliver top-tier expertise, products, and solutions to better serve our customers.

Our partnership with ThreatGEN and the utilization of their AI-driven “AutoTableTop” tool not only utilizes our experience with TSA guidelines, but adds an element of reality that the traditional methods are lacking, making these engagements more interactive and beneficial for operators who are required to participate annually.

In 2024, UTSI also invested heavily in AI and Data Science by acquiring Houston-based AI company Pandata Tech and leveraging their Data-Quality-Methodology (DQM), Leak Geek, and time-series data science expertise to solve industry specific problems.

Moving up – in and around Houston

Building on our recent successes, we strategically relocated our office to the Netrality building (1301 Fannin St.), bringing us closer to clients and partners, while getting access to a Tier 3 Data Center with an uninterrupted 40-year power record.

Netrality is a SOC2-compliant facility with seven points of detection from the street to our server, including biometric screening. Our very own Roberto deLeon has architected our upgraded servers using the Purdue model as a basis of design while leveraging our relationship with Fortinet to standardize our hardware and software to the highest standards. We practice what we preach — every architecture, framework, and hardware recommendation we make is not just advised but actively implemented within our own operations.

Our investment in this space includes increasing our “SCADA R&D Lab” to play with toys from vendors, testing them out in our environment before we recommend and advise them to our clients and partners. Currently we’re working on LLMs for OT, building our own “DANN2.0” for use in-house. DANN is an homage to Dan Nagala (and, for the nerds, stands for Dan Artificial Neural Network), which we started in 2022 when I realized that knowledge capture is an industry wide epidemic and we need to be ready to integrate for our clients in a safe and local way at scale, in the OT environment.

Additionally, having come from a startup before joining UTSI, I wanted to get us closer to the heart of innovation, so we’ve added additional office space at The Cannon downtown. While there are many tech hubs around Houston, and we are proud to work with and partner with companies from Greentown Labs and the Ion, to name a few, we’ve found that The Cannon community is incredibly active and innovative, with experience in industrial use-cases.

Houston is set to become the Energy Transition capital, leading in hydrogen, carbon capture, and repurposing. With a 5:1 ratio of engineers leaving the industry and an average age over 60, we must innovate. The solution lies in combining a secure, cloud-free "ChatGPT for OT" with digital twins. Bringing the field to engineers is essential. We've partnered with a satellite constellation for asset imaging and U.K.-based Mods Solutions to leverage their CFIHOS-driven platform for intelligent digital twins — more on that partnership soon!

And we will need to leverage enhanced automation tools and actively monitor control networks to ensure security and respond quickly to issues, which is why we’ve partnered with Nozomi Networks.

Shaping the future

Although Dan has semi-retired to his cabin in Montana, he continues to do “the fun stuff” that brings him joy, such as conducting research for PRCI and assisting long-time clients. He also has been a mentor and advisor to me since I started at UTSI three years ago. I’m grateful for him and the group of industry experts he gathered around him to make UTSI such a well-known systems integrator and OT advisor for the world’s largest asset owners.

Our group of experts are active in the industry and will be speaking at events throughout the year, with a presence at Entellec, Level Zero, and participating at this year's API Cybernetics and PSIGs biannual conferences. We proudly serve on the BCarbon advisory board and GHPs Energy Committee.

Lastly, we have one request: We see a critical need for H2 and supercritical CO2 studies to develop simulation models, response plans, and leak detection best practices. These gases differ from those covered in existing standards. If you know anyone interested in funding or contributing, we’re collaborating with industry partners to secure support.

Houston named No. 2 most diverse major U.S. city for 2025

Ranking It

Houston has always been a diverse place, embracing people of many different cultural and socioeconomic backgrounds. And the city is earning new recognition in WalletHub's rankings of the most diverse large American cities for 2025.

The 2025 edition is the final installment in WalletHub's diversity study series, which annually compared 501 U.S. cities across 13 metrics in five categories that encompass "diversity" across socioeconomic, cultural, economic, household, and religious factors.

Cities were also ranked by population, with large cities defined as those with over 300,000 residents, midsize cities with 100,000 to 300,000 residents, and small cities with fewer than 100,000 residents.

Houston nearly topped the list of large U.S. cities, coming in at No. 2, and ranked at No. 5 in the overall national comparison.

The top three most diverse American cities, which have held their positions for the second consecutive year, are all located in Maryland: Gaithersburg (No. 1), Silver Spring (No. 2), and Germantown (No. 3).

Houston performed spectacularly in the study's overall rankings for socioeconomic (No. 14), cultural (No. 32), and religious diversity (No. 63), but fell behind in the categories for household (No. 129) and economic diversity (No. 165).

In the more detailed comparisons across educational-attainment, linguistic, and industry diversity, Houston ranked among the top 30 in all three categories out of the 501 cities included in the report.

Here's how Houston performed across the remaining eight categories in the study:

  • No. 44 – Racial and ethnic diversity
  • No. 129 – Household type diversity
  • No. 200 – Household size diversity
  • No. 201 – Income diversity
  • No. 207 – Occupational diversity
  • No. 239 – Birthplace diversity
  • No. 284 – Age diversity
  • No. 343 – Worker-class diversity

Embracing diversity is not only good for local communities, it's also beneficial for the economy, the report says.

"Not only have waves of immigration changed the face of the nation, they’ve also brought in fresh perspectives, skills, and technologies to help the U.S. develop a strong adaptability to change," the report's author wrote. "Economies generally fare better when they openly embrace and capitalize on new ideas. Conversely, those relying on old ways and specialized industries tend to be hurt more by changes in the market."

Houston is a repeat performer: It slipped one spot from its 2024 ranking, and previously topped the overall list in 2021 — showing that the city has consistently maintained in diversity over the years.

Other diverse Texas cities
Elsewhere in Texas, Arlington surpassed Houston as the No. 4 overall most diverse city, and took the No. 1 spot in the "large city" category.

Dallas ranked just outside the top 10 this year, landing in 11th place after previously ranking eighth overall in 2024. Dallas also appeared in sixth place in the national rankings for the most diverse large cities, so the city still has some catching up to do.

Fort Worth fell into No. 25 overall this year, in a three-place slip from last year's ranking. The city performed the best in the overall categories for socioeconomic and cultural diversity, earning a respective No. 58 and No. 61.

The top 10 most diverse cities in America in 2025 are:

  • No. 1 – Gaithersburg, Maryland
  • No. 2 – Silver Spring, Maryland
  • No. 3 – Germantown, Maryland
  • No. 4 – Arlington, Texas
  • No. 5 – Houston, Texas
  • No. 6 – New York, New York
  • No. 7 – Charlotte, North Carolina
  • No. 8 – Jersey City, New Jersey
  • No. 9 – Danbury, Connecticut
  • No. 10 – Los Angeles, California
