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."

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.

2 Houston suburbs named among 10 best places to live by U.S. News & World Report

Where to Live

The Houston suburbs of Pearland and League City have landed among the top 10 best places to live in 2025, according to U.S. News & World Report.

New for the 2025-2026 "Best Places to Live in the U.S." rankings, U.S. News expanded its coverage from 150 to 250 U.S. cities, and updated its methodology to examine each city based on five livability indexes: Quality of life, value, desirability, job market, and net migration.

Pearland ranked No. 3 nationwide, earning a 7.0 score alongside No. 1-winning Johns Creek, Georgia and No. 2 winner Carmel, Indiana.

Pearland also landed on top of U.S. News separate rankings of the best places to live in Texas for 2025-2026.

Some facts about Pearland that put it at the top of the list include its median household income ($115,504), its median home values ($319,753), and its bustling population of nearly 124,000 residents.

Housing costs in Pearland are extremely attractive compared to other places in the country, as the national average home is worth over $370,000. It's no wonder this Houston neighbor has been adding more high-income households than many other places in Texas.

Pearland's population is a healthy mix of young individuals and families, with 29 percent of residents under 20 years old and 36 percent of the population between the ages of 20-44. Nearly a quarter of Pearland's population is between 45-64-years-old, while only 12 percent of residents are over 65, the report says.

Pearland's reputation as one of the safest cities in America is also boosting its community appeal.

"Finding a community to be part of can play a major role in making a place feel like home," U.S. News said. "If you’re a parent with young children, you may want to live in a neighborhood with other people in that phase of life. If you’re a professional moving to a hot job market for your field, you may want to live in an apartment close to the office or within walking distance of friends and colleagues."

Pearland also enjoys a better job market than other cities, the report added. Pearland's unemployment rate as of 2023 was only 3.6 percent, lower than the national average unemployment rate of 4.5 percent.

However, if people are looking for a public transportation-friendly city, they may need to look elsewhere. Almost all commuters in Pearland drive to their workplaces, making access to a vehicle absolutely necessary for living in the suburb. Pearland's 31.2-minute average commute time is also 9.2 minutes higher than the national average, U.S. News said.

Other Houston-area suburbs

League City ranked three spots behind Pearland as the 6th best place to live in the U.S., and No. 2 in Texas. The city boasts a median household income of $120,670, and affordable median home values at $327,511.

Workers in League City also predominantly rely on vehicles for their daily commutes, and only 3.7 percent of the population use public transport to get to work. Commuters spend an average time of 27.5 minutes driving to work, U.S. News determined.

More than half (63.5 percent) of all League City residents are married, and 54 percent of the population are between the ages of 25 and 64-years-old.

Here's how other Houston-area cities faired among the top 100:

  • No. 16 – Sugar Land
  • No. 44 – The Woodlands
  • No. 45 – Katy
  • No. 67 – Missouri City
  • No. 73 – Spring

Houston drops out of the top 100

Though Houston proper made substantial improvements to land among the top 100 best places to live in U.S. News' 2024-2025 report, the city has once again plummeted toward the bottom of the list for 2025-2026.

Houston slumped to No. 381 this year, and only ranked No. 63 in the statewide comparison, showing that the city has lost its charm in favor of its appealing suburban neighbors.

The top 10 best places to live in the U.S. are:

  • No. 1 – Johns Creek, Georgia
  • No. 2 – Carmel, Indiana
  • No. 3 – Pearland, Texas
  • No. 4 – Fishers, Indiana
  • No. 5 – Cary, North Carolina
  • No. 6 – League City, Texas
  • No. 7 – Apex, North Carolina
  • No. 8 – Leander, Texas
  • No. 9 – Rochester Hills, Michigan
  • No. 10 – Troy, Michigan
