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.

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.

In light of COVID-19, it is more relevant than ever to discuss and support startups with sustainability and resiliency in mind. At The Ion Smart and Resilient Cities Cohort 2 Demo Day, a virtual audience was reminded of that.

"So, 2020 has certainly been a year of unprecedented uncertainty and change for Houston, for Texas, for our country, and for our world," says Christine Galib, director of the accelerator. "The past few months in particular have been especially difficult as the global pandemic and civil unrest continue to spotlight systemic and structural scars on the face of humanity."

The virtual event was streamed on July 1 and hosted several thought leaders and presenters before concluding with pitches from four of the cohort companies.

"Through it all, and in a virtual world, Cohort 2 startups, the mentors, and our Ion team have been the change we wish to see in the world," Galib continues. "For these startups, failure is simply not an option — and neither is going at it alone."

Earlier this year, Galib announced the second cohort would be focused on solutions for Houston's air quality, water purification, and other cleantech needs. The program, backed by Intel, Microsoft, and TX/RX, launched on Earth Day and commenced shortly after. Cohort 3 is expected later this year.

Here are the four companies that pitched and the problems they are trying to solve.

Re:3D

re:3D was founded just down the street from NASA's Johnson Space Center to address the need for a mid-market 3D printing solution. The Houston-based startup also wanted to create their 3D printer that operates on recycled plastics in order to prevent excess waste.

"Where some see trash, we see opportunity," Charlotte Craff, community liaison at Re:3D says in her presentation.

Re:3D's clients can get their hands on their own Gigabot for less than $10,000, and the printer uses pellets and flakes from recycled plastics —not filament — to print new designs. Clients are also supported by the company with design software and training.

"We can help the city of Houston help meet its climate action and resilient city goals by transforming the way people think about recycling," Craff says about Re:3D's future partnerships with the city.

Water Lens

While two-thirds of the world is covered in water, only 0.7 percent is drinkable. And of that fresh water, 92 percent of it is used in agricultural and industrial settings. This is how Keith Cole, CEO and founder of Water Lens, set the scene for his presentation.

Water Lens, which is based in Houston with a lab located in Austin, wants to solve the problem of cities and countries running out of fresh, drinkable water by equipping huge water-using companies with a water testing tool.

"We've developed a system to let anyone test any water literally anywhere in the world," Cole says, citing clients like ExxonMobil, Shell, and Halliburton.

S2G Energy

S2G Energy, based in Mexico, is focused on optimizing energy management in order to digitize, empower, and unlock potential for cost-saving efforts and technology.

In his pitch, Geronimo Martinez, founder of S2G Energy, points out that restaurants, commercial buildings, and other adjacent industries can save money by implementing energy management solutions that come out of S2G Energy's expertise. In Mexico, Martinez says, clients include the top two restaurant chains that — especially during COVID-19 — need optimization and cost saving now more than ever.

Eigen Control

A refinery's distillation columns are expensive — their fuel use accounts for 50 of operating costs, says Dean Guma, co-founder and CEO of Houston-based Eigen Control.

Guma explains in his pitch how Eigen Control's technology can plug into existing sensors, model networks based on data, and employ the startup's artificial intelligent technology to reduce carbon emissions and save money on operating costs.

New initiative to bring protective equipment to underserved parts of Houston

PPE for the people

Through a collaboration between a 3D printing company and a nonprofit organization, small businesses in underserved parts of town are able to apply to receive personal protective equipment donations.

Impact Hub Houston and re:3D have teamed up for an initiative called PPE For The People that will create and donate PPE to small businesses disproportionately affected by the coronavirus outbreak.

"All of the emerging data indicates that, while a coronavirus may not discriminate, disparities that already exist in society are putting communities of color at a disproportionately higher risk of infection, serious illness, and death from COVID-19," says Grace Rodriguez, CEO and executive director of Impact Hub Houston.

According to a news release, the initiative will support workers across industries — from restaurants employees and bus and delivery drivers to small businesses that seek to reopen safely, like barbershops and nail salons.

Impact Hub Houston works to prioritize inclusion in Houston, which has been recognized as the most diverse city in the nation.

"There a number of societal factors that are leading to disproportionately higher COVID-19 cases and deaths among minority communities," says Rodriguez, specifying that these factors include lack of access to health care, overrepresentation of people of color in jobs considered essential, and more.

To start, the initiative has identified the southeast, south, and southwest parts of Houston to deliver four types of 3D-printed PPE: face shields, ear savers, hands-free door opener, and splash guards.

"re:3D has extensively researched PPE production for COVID-19 throughout the crisis as well as collaborated with healthcare workers, first responders, and local businesses to identify where there are gaps in their ability to protect themselves and their customers," says re:3D's community liaison, Charlotte Craff. "We have started with these items because we are confident they fill those needs."

The campaign, which is raising money and seeking volunteers online, began Wednesday, May 6, and expects to deliver its first PPE next week. The organizations are looking into expanding the PPE offered, as well as their reach, but it depends on fundraising.

"We would like to expand the project to serve communities in the northeast and other high-risk areas of Houston, but that all depends on how much funding we can raise to keep producing and delivering PPE," Rodriguez explains.

According to the release, Impact Hub Houston is financially supporting the initiative through its Fiscal Sponsorship Program, which re:3D applied to. The H-Force network, a crisis collaboration, is also lending its support to this initiative.

"We are honored to help those who are most vulnerable," says Craff in the release. "Data from the CDC has shown minority communities are at greater risk of critical illness from COVID-19, and we want to help local small businesses protect their employees as best as possible without it being an added financial burden on already strained industries."

Texas cybersecurity co. expands unique train-to-hire model to Houston

job search

It’s increasingly more difficult to ensure the confidentiality, integrity, and availability of proprietary data and information in the ever-changing, ever-evolving digital world.

Cyberattacks, including malware, phishing, and ransomware, are becoming increasingly common and sophisticated, posing a consistent threat to a company’s sustainability and bottom line.

To combat that trend, Nukudo, a San Antonio-based cybersecurity workforce development company, is expanding its initiative to bridge the global cybersecurity talent gap through immersive training and job placement to Houston.

“We saw that there was a need in the market because there's a shortage of skilled manpower within the cybersecurity industry and other digital domains,” says Dean Gefen, CEO of NukuDo. “So, our initial goal was to take a large pool of people and then make them to be fully operational in cybersecurity in the shortest amount of time.”

The company refers to the plan as the “training-to-employment model,” which focuses on providing structured training to select individuals who then acquire the skills and knowledge necessary to secure and maintain fruitful careers.

The company identifies potential associates through its proprietary aptitude test, which recognizes individuals who possess the innate technical acumen and potential for success in various cybersecurity roles, regardless of their level of education.

“We take in people from all walks of life, meaning the program is purely based on the associate’s potential,” Gefen says. “We have people who were previously aircraft engineers, teachers, graphic designers, lawyers, insurance agents and so forth.”

Once selected, associates are trained by cybersecurity experts while gaining hands-on experience through scenario-based learning, enabling them to be deployed immediately as fully operational cybersecurity professionals.

The program training lasts just six months—all paid—followed by three years of guaranteed employment with NukuDo.

While in training, associates are paid $ 4,000 per month; then, they’re compensated by nearly double that amount over the next three years, ultimately pushing their salaries to well into the six figures after completing the entire commitment.

In addition to fostering a diverse talent pipeline in the cybersecurity field, NukuDo is creating a comprehensive solution to address the growing shortage of technical talent in the global workforce.

And arming people with new marketable skills has a litany of benefits, both professional and personal, Gefen says.

“Sometimes, we have associates who go on to make five times their previous salary,” says Gefen. “Add to that fact that we had someone that had a very difficult life beforehand and we were able to put him on a different path. That really hits home for us that we are making a difference.

Nulkudo currently has partnerships with companies such as Accenture Singapore and Singapore Airlines. Gefen says he and his team plans to have a new class of associates begin training every month by next year and take the model to the Texas Triangle (Houston, Austin and Dallas)—then possibly nationwide.

“The great thing about our program is that we train people above the level of possible threat of replacement by artificial intelligence,” Gefen says. “But what we are also doing, and this is due to requirements that we have received from clients that are already hiring our cyber professionals, is that we are now starting to deliver AI engineers and data scientists in other domains.”

“That means that we have added more programs to our cybersecurity program. So, we're also training people in data science and machine learning,” he continues.

All interested candidates for the program should be aware that a college degree is not required. NukuDo is genuinely interested in talented individuals, regardless of their background.

“The minimum that we are asking for is high school graduates,” Gefen says. “They don't need to have a college degree; they just need to have aptitude. And, of course, they need to be hungry to make this change.”

2 Houston universities declared among world’s best in 2026 rankings

Declaring the Best

Two Houston universities are in a class of their own, earning top spots on a new global ranking of the world's best universities.

Rice University and University of Houston are among the top 1,200 schools included in the QS World University Rankings 2026. Ten more schools across Texas make the list.

QS (Quacquarelli Symonds), a London-based provider of higher education data and analytics, compiles the prestigious list each year; the 2026 edition includes more than 1,500 universities from around the world. Factors used to rank the schools include academic reputation; employer reputation; faculty-student ratio; faculty research; and international research, students, and faculty.

In Texas, University of Texas at Austin lands at No. 1 in the state, No. 20 in the U.S., and No. 68 globally.

Houston's Rice University is close behind as Texas' No. 2 school. It ranks 29th in the U.S. and No. 119 in the world. Unlike UT, which fell two spots globally this year (from No. 66 to 68), Rice climbed up the charts, moving from 141st last year to No. 119.

University of Houston impresses as Texas' 4th highest-ranked school. It lands at No. 80 in the U.S. and No. 556 globally, also climbing about 100 spots up the chart.

Rice and UH are on a roll in regional, national, and international rankings this year.

Rice earned top-15 national rankings by both Niche.com and Forbes last fall. Rice claimed No. 1 and UH ranked No. 8 in Texas in U.S. News & World Report's 2025 rankings. Rice also topped WalletHub's 2025 list of the best colleges and universities in Texas for 2025.

More recently, in April, both UH and Rice made U.S. News' 2025 list of top grad schools.

In all, 192 U.S. universities made the 2026 QS World University Rankings — the most of any country. Topping the global list is the Massachusetts Institute of Technology (MIT).

“The results show that while U.S. higher education remains the global leader, its dominance is increasingly challenged by fast-rising emerging systems,” says the QS World University Rankings report. “A decade ago, 32 American universities [were] featured in the world’s top 100; today, that number has dropped to 26, and only 11 of these institutions have improved their position this year."

The 12 Texas universities that appear in the QS World University Rankings 2026 list are:

  • University of Texas at Austin, No. 20 in the U.S. and No. 68 in the world (down from No. 66 last year).
  • Rice University, No. 29 in the U.S. and No. 119 in the world (up from No. 141 last year).
  • Texas A&M University, No. 32 in the U.S. and No. 144 in the world (up from No. 154 last year).
  • University of Houston, No. 80 in the U.S. and No. 556 in the world (up from 651-660 last year).
  • University of Texas at Dallas, No. 85 in the U.S. and No. 597 in the world (down from 596 last year).
  • Texas Tech University, No. 104 in the U.S. and No. 731-740 in the world (unchanged from last year).
  • University of North Texas, No. 123 in the U.S. and No. 901-950 in the world (up from 1,001-1,200 last year)
  • Baylor University, tied for No. 136 in the U.S. and at No. 1,001-1,200 in the world (unchanged from last year).
  • Southern Methodist University, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas Arlington, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at San Antonio, tied for No. 136 in the U.S. and at 1,001-1,200 in the world (unchanged from last year).
  • University of Texas at El Paso, No. 172 in the U.S. and at 1,201-1,400 in the world (down from 1,001-1,200 last year).

Houston students develop new device to prepare astronauts for outer space

space race

Rice University students from the George R. Brown School of Engineering and Computing designed a space exercise harness that is comfortable, responsive, and adaptable and has the potential to assist with complex and demanding spacewalks.

A group of students—Emily Yao, Nikhil Ashri, Jose Noriega, Ben Bridges and graduate student Jack Kalicak—mentored by assistant professor of mechanical engineering Vanessa Sanchez, modernized harnesses that astronauts use to perform rigorous exercises. The harnesses are particularly important in preparing astronauts for a reduced-gravity space environment, where human muscles and bones atrophy faster than they do on Earth. However, traditional versions of the harnesses had many limitations that included chafing and bruising.

The new harnesses include sensors for astronauts to customize their workouts by using real-time data and feedback. An additional two sensors measure astronauts’ comfort and exercise performance based on temperature and humidity changes during exercise and load distribution at common pressure points.

“Our student-led team addressed this issue by adding pneumatic padding that offers a customized fit, distributes pressure over a large surface area to reduce discomfort or injuries and also seamlessly adapts to load shifts — all of which together improved astronauts’ performance,” Sanchez said in a news release. “It was very fulfilling to watch these young engineers work together to find innovative and tangible solutions to real-world problems … This innovative adjustable exercise harness transforms how astronauts exercise in space and will significantly improve their health and safety during spaceflights.”

The project was developed in response to a challenge posted by the HumanWorks Lab and Life Science Labs at NASA and NASA Johnson Space Center for the 2025 Technology Collaboration Center’s (TCC) Wearables Workshop and University Challenge, where teams worked to solve problems for industry leaders.

Rice’s adaptive harness won the Best Challenge Response Award. It was funded by the National Science Foundation and Rice’s Office of Undergraduate Research and Inquiry.

“This challenge gave us the freedom to innovate and explore possibilities beyond the current harness technology,” Yao added in the release. “I’m especially proud of how our team worked together to build a working prototype that not only has real-world impact but also provides a foundation that NASA and space companies can build and iterate upon.”
