An innovative project led by Houston-founded re:3D Inc. is one of six to move forward to the next phase of the National Science Foundation's Convergence Accelerator that aims to drive solutions with societal and economic impact.

The sustainable 3D printer company will receive up to $5 million over three years as it advances on to Phase 2 of the program for its ReCreateIt project, according to a statement from the NSF. Co-funded by Australia's national science agency, the Commonwealth Scientific and Industrial Research Organisation, or CSIRO, ReCreateIt enables low-income homeowners to design sustainable home goods using recycled plastic waste through 3D-printing at its net-zero manufacturing lab.

The project is in partnership with Austin Habitat for Humanity ReStores and researchers from the University of Wollongong and Western Sydney University. CSIRO is funding the Australian researchers.

In Phase II the teams will receive training on product development, intellectual property, financial resources, sustainability planning and communications and outreach. The goal of the accelerator is to promote a "circular economy," in which resources are reused, repaired, recycled or refurbished for as long as possible.

"Progress toward a circular economy is vital for our planet's health, but it is a complex challenge to tackle," Douglas Maughan, head of the NSF Convergence Accelerator program, said in the statement. "The NSF Convergence Accelerator program is bringing together a wide range of expertise to develop critical, game-changing solutions to transition toward a regenerative growth model that reduces pressure on natural resources, creates sustainable growth and jobs, drastically reduces waste and ultimately has a positive impact on our environment and society. Phase 2 teams are expected to have strong partnerships to ensure their solutions are sustained beyond NSF support."

Other teams that are moving forward in the accelerator include:

  • FUTUR-IC: A global microchip sustainability alliance led by MIT
  • PFACTS: Led by IBM's Almaden Research Center and aiming to replace, redesign and remediate fluorine-containing per- and polyfluoroalkyl substances (PFAS)
  • SOLAR: A team led by Battelle Memorial Institute using photovoltaic circularity to develop the technology needed to achieve sustainable solar recycling
  • SpheriCity: A cross-sector tool that examines how plastics, organics and construction and demolition materials flow through local communities developed by the University of Georgia Research Foundation Inc.
  • Topological Electric: Another MIT-led team, this group aims to develop electronic and energy-harvesting device prototypes based on topological materials.

Re:3d and 15 other teams were first named to the Convergence Accelerator in 2022 with a total investment of $11.5 million. At the end of Phase 1, the teams participated in a formal Phase 2 proposal and pitch, according to the NSF. The Convergence Accelerator was launched in 2019 as part of the NSF's Directorate for Technology, Innovation and Partnerships.

This is the latest project from re:3D to land national attention and funding. Last year the company was one of 12 to receive up to $850,000 from NASA's SBIR Ignite pilot for its project that aimed 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.

In 2022, it was also among the winners of an inaugural seed fund expo from the U.S. Small Business Administration. It also earned the prestigious Tibbetts Award from the SBA in 2021. The award honors small businesses that are at the forefront of technology.

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. The company announced its new Austin headquarters earlier this year.

Houston 3D printing company lands funding from NASA

funds granted

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.

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 doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
