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."

Intuitive Machines to buy satellite maker Lanteris for $800M

space deal

Houston-based aerospace company Intuitive Machines has agreed to buy satellite manufacturer Lanteris Space Systems for $800 million from private equity firm Advent International.

Intuitive Machines co-founder, president and CEO Steve Altemus said the combined revenue of his company and Palo Alto, California-based Lanteris exceeded $850 million as of Sept. 30, and their backlog of orders totaled $920 million.

Until recently, Lanteris operated as Maxar Space Systems. Its origins date back to 1957.

The deal—comprising $450 million in cash and $350 million in Class A shares of Intuitive Machines stock—is expected to close in the first quarter of 2026.

The acquisition “marks the moment Intuitive Machines transitions from a lunar company to a multi-domain space [company], setting the pace for how the industry’s next generation will operate,” Altemus said.

Altemus said the acquisition would enable Intuitive Machines to better compete for Earth orbit, lunar, Mars and deep space projects. Among the opportunities that would open up thanks to the Lanteris deal are the proposed Golden Dome missile defense system and a large lunar lander capable of carrying astronauts, he said.

“The new Intuitive Machines will combine rapid innovation and precision spacecraft production to meet the growing demand for responsive, high-reliability space infrastructure and services,” Altemus said.

Intuitive Machines, founded in 2013, develops lunar landers and provides aerospace services. In 2024, it became the first U.S. company to land a spacecraft on the moon in half a century.

Altemus said Intuitive Machines is already building three satellites for NASA’s near-space network, and it might upsize two more satellites now that it plans to buy Lanteris.

Aside from satellites, Lanteris is developing the power and propulsion element for NASA’s Gateway, a lunar orbiting command module that will support Artemis missions and deep space exploration.


Lanteris was a division of Maxar Technologies, which Advent and minority investor British Columbia Investment Management took private in a 2023 deal valued at $6.4 billion

Anil Shetty, InformAI

Anil Shetty serves as president and chief medical officer for biotech company Ferronova and chief innovation officer for InformAI. He's mentored numerous medical device and digital health companies at seed or Series A, including Pathex, Neurostasis, Vivifi Medical and many others. He mentors through organizations like Capital Factory, TMC Biodesign, UT Venture Mentoring, UTMB Innovation and Rice's Global Medical Innovation program.

"Being a mentor means empowering early-stage innovators to shape, test, and refine their ideas with clarity and purpose," Shetty says. "I’m driven by the opportunity to help them think strategically and pivot early before resources are wasted. At this critical stage, most founders lack the financial means to bring on seasoned experts and often haven’t yet gained real-world exposure. Mentorship allows me to fill that gap, offering guidance that accelerates their learning curve and increases the chances of meaningful, sustainable impact."

Jason Ethier, EnergyTech Nexus

Jason Ethier is the founding partner of EnergyTech Nexus, through which he has mentored numerous startups and Innovation Awards finalists, including Geokiln, Energy AI Solutions, Capwell Services and Corrolytics. He founded Dynamo Micropower in 2011 and served as its president and CEO. He later co-founded Greentown Labs in Massachusetts and helped bring the accelerator to Houston.

"Being a mentor means using my experience to help founders see a clearer path to success. I’ve spent years navigating the ups and downs of building companies, struggling with cash flow, and making all the mistakes; mentoring gives me the chance to share those lessons and show entrepreneurs the shortcuts I wish I’d known earlier," Ethier says. "At Energytech Nexus, that role goes beyond just helping individual founders — it’s about creating a flywheel effect for Houston’s entire innovation ecosystem."

Jeremy Pitts, Activate Houston

Jeremy Pitts serves as managing director of Activate Houston, which launched in Houston last year. He was one of the founders of Greentown Labs in the Boston area and served in a leadership role for the organization between 2011 and 2015. Through Activate, he has mentored numerous impactful startups and Innovation Awards finalists, including Solidec, Coflux Purification, Bairitone Health, Newfound Materials, Deep Anchor Solutions and others.

"Being a mentor to me is very much about supporting the person in whatever they need. Oftentimes that means supporting the business—providing guidance and advice, feedback, introductions, etc," But just as important is recognizing the person and helping them with whatever challenges they are going through ... Sometimes they need a hype man to tell them how awesome they are and that they can go do whatever hard thing they need to do. Sometimes they just need an empathetic listener who can relate to how hard these things are. Being there for the person and supporting them on their journey is key to my mentorship style."

Joe Alapat, Liongard

Joe Alapat founded and serves as chief strategy officer at Houston software company Liongard and chief information officer at Empact IT, which he also owns. He mentors through Founder Fridays Houston Group, Software Day by Mercury Fund, SUPERGirls SHINE Foundation, Cup of Joey and at the Ion. He's worked with founders of FlowCare, STEAM OnDemand, Lokum and many other early stage startups.

"Being a mentor to me means unleashing an individual’s 10x—their purpose, their ikigai (a Japanese concept that speaks to a person’s reason for being)," Alapat says. "Mentoring founders in the Houston community of early stage, high-growth startups is an honor for me. I get to live vicariously through a founder’s vision of the future. Once they show me that compelling vision, I’m drawn to bring the future forward with them so the vision becomes reality with a sense of urgency."

Neal Dikeman, Energy Transition Ventures

Neal Dikeman serves as partner at early stage venture fund Energy Transition Ventures, executive in residence at Greentown Labs, and offices in and supports Rice Nexus at the Ion. He mentors startups, like Geokiln, personally. He also mentored Helix Earth through Greentown Labs. The company went on to win in the Smart Cities, Transportation & Sustainability contest at SXSW earlier this year. Dikeman has helped launch several successful startups himself, most recently serving on the board of directors for Resilient Power Systems, which was acquired by Eaton Corp for $150 million.

"Founders have to find their own path, and most founders need a safe space where they can discuss hard truths outside of being 'on' in sales mode with their team or board or investors, to let them be able to work on their business, not just in it," Dikeman says.

Nisha Desai, Intention

Nisha Desai serves as CEO of investment firm Intention and mentors through Greentown Labs, TEX-E, Open Minds, the Rice Alliance Clean Energy Accelerator, Avatar Innovations and The Greenhouse. She currently works with founders from Solidec, Deep Anchor Solutions, CLS Wind and several other local startups, several of which have been nominated for Innovation Awards this year. She's served a board member for Greentown Labs since 2021.

"When I first started mentoring, I viewed my role as someone who was supposed to prevent the founder from making bad decisions. Now, I see my role as a mentor as enabling the founder to develop their own decision-making capability," Desai says. "Sometimes that means giving them the space to make decisions that might be good, that might be bad, but that they can be accountable for. At the end of the day, being a mentor is like being granted a place on the founder's leadership development journey, and it's a privilege I'm grateful for."

Rice, Houston Methodist developing soft 'sleep cap' for brain health research

Researchers and scientists at Rice University and Houston Methodist are developing a “sleep cap” that aims to protect the brain against dementia and other similar diseases by measuring and improving deep sleep.

The project is a collaboration between Rice University engineering professors Daniel Preston, Vanessa Sanchez and Behnaam Aazhang; and Houston Methodist neurologist Dr. Timea Hodics and Dr. Gavin Britz, director of the Houston Methodist Neurological Institute and chairman of the Department of Neurosurgery.

According to Rice, deep sleep is essential for clearing waste products from the brain and nightly “cleaning cycles” help remove toxic proteins. These toxic proteins, like amyloids, can accumulate during the day and are linked to Alzheimer’s disease and other neurological issues.

Aazhang, director of the Rice Neuroengineering Initiative, and his team are building a system that not only tracks the brain’s clearing process but can also stimulate it, improving natural mechanisms that protect against neurodegeneration.

Earlier proof-of-concept versions of the caps successfully demonstrated the promise of this approach; however, they were rigid and uncomfortable for sleep.

Preston and Sanchez will work to transform the design of the cap into a soft, lightweight, textile-based version to make sleep easier, while also allowing the caps to be customizable and tailored for each patient.

“One of the areas of expertise we have here at Rice is designing wearable devices from soft and flexible materials,” Preston, an assistant professor of mechanical engineering, said in a news release. “We’ve already shown this concept works in rigid device prototypes. Now we’re building a soft, breathable cap that people can comfortably wear while they sleep.”

Additionally, the research team is pursuing ways to adapt their technology to measure neuroinflammation and stimulate the brain’s natural plasticity. Neuroinflammation, or swelling in the brain, can be caused by injury, stroke, disease or lifestyle factors and is increasingly recognized as a driver of neurodegeneration, according to Rice.

“Our brain has an incredible ability to rewire itself,” Aazhang added in the release. “If we can harness that through technology, we can open new doors for treating not just dementia but also traumatic brain injury, stroke, Parkinson’s disease and more.”

The project represents Rice’s broader commitment to brain health research and its support for the Dementia Prevention Research Institute of Texas (DPRIT), which passed voter approval last week. The university also recently launched its Rice Brain Institute.

As part of the project, Houston Methodist will provide access to clinicians and patients for early trials, which include studies on patients who have suffered traumatic brain injury and stroke.

“We have entered an era in neuroscience that will result in transformational cures in diseases of the brain and spinal cord,” Britz said in the release. “DPRIT could make Texas the hub of these discoveries.”
