At first, Zimri T. Hinshaw just wanted to design a sustainable, vegan jacket inspired by bikers he saw in Tokyo. Now, he's running a bio-based materials company with two product lines and is ready to disrupt the fashion and automotive industries.

Hinshaw founded Rheom Materials (née Bucha Bio) in 2020, but a lot has changed since then. He moved the company from New York to Houston, built out a facility in Houston's East End Maker Hub, and rebranded to reflect the company's newest phase and extended product lines, deriving from dozens of different ingredients, including algae, seaweed, corn, other fruits and vegetables, and more.

"As a company, we pivoted our technology from growing kombucha sheets to grinding up bacteria nanocellulose from kombucha into our products and then we moved away from that entirely," Hinshaw says on the Houston Innovators Podcast. "Today, we're designing different materials that are more sustainable, and the inputs are varied."

Now, in addition to Rheom's leather-like alternative, Shorai, the company has a plastic-like material, Benree, that's 100 percent bio based.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," Hinshaw says.

With that major evolution past just kombucha-based textiles, it was time for a new name, ideated by the company's technical team. "Rheom" is the combination of "rheology" — the study of how polymers flow — and "form."

Rheom has also built a state-of-the-art chemicals testing lab at its new facility after moving into it early last year.

"We've got a ton of capabilities now — and we've been growing those since the beginning," Hinshaw says. "Now we have all this testing equipment — things that pull materials apart, things that test the flexibility of materials."

Next up, Rheom, which is backed by Houston-based New Climate Ventures, among other VCs, will raise a series A funding round to continue supporting its growth.

Houston nonprofit accelerator receives grant funding to advance bioindustrial startups

funds granted

A Houston-based nonprofit accelerator that works with early-stage synthetic biology startups has secured nearly $750,000 to support its mission.

First Bight Ventures' accelerator, BioWell, secured $741,925 of the $53 million doled out as a part of the "Build to Scale" Grant program that the U.S. Economic Development Administration, a division of the U.S. Department of Commerce, has established. First Bight was one of 60 organizations to receive funding.

The funding will support the BioWell's mission to establish a "vibrant bioeconomy" by helping startups scale and commercialize "through access to a unique combination of pilot bioproduction infrastructure," according to a news release from First Bight.

"Startups at BioWell will gain access to a robust ecosystem, expertise, mentorship, and financial resources essential for successfully commercializing their bio-industrial innovations," BioWell Executive Director Paul Palmer says in the release.

The BioWell is still working toward establishing a physical space and has worked out of the East End Maker Hub in the meantime. The organization has partnered with Urban Partnerships Community Development Corporation, or UP CDC, which led the application process on this federal grant.

"BioWell chose to partner with UP CDC for the EDA grant, to continue the successful model that UP CDC has created at the East End Maker Hub for advanced manufacturing. UP CDC looks forward to continuing our partnership with BioWell in the UP CDC's BioCity project that will position Houston at the forefront of bio-manufacturing," UP CDC's CEO Patrick Ezzell says in the release.

First Bight Ventures Founder Veronica Wu established the BioWell to target high-potential startups, which usually have to overcome lack of funding challenges early on.

"Often times, early-stage startups gain momentum and hit important milestones, but ultimately find themselves heading toward the 'Valley of Death,' where progress is made on their enterprise, but no sufficient revenue is generated for the company's stability and longevity," Wu says in the release. "This 'Build to Scale' program's support will help offset these inevitable challenges in our bio-industrial space."

She shares more about her mission for First Bight Ventures on the Houston Innovators Podcast. Listen to the interview from March below.

$32M resilience-focused hub to rise in Houston's East End

coming soon

A first-of-its-kind manufacturing hub designed to “future proof” residential, commercial, industrial, and public sector infrastructure is coming to Houston.

The 130,000-square-foot Resilience Manufacturing Hub will house functions such as R&D, manufacturing, and assembly for products aimed at improving the resilience of homes, office buildings, warehouses, and other components of the “built environment.”

“We are looking for any product or technology solution that can reduce the impact from the next generation of disasters … by helping people thrive, not just survive, in their own community,” says Richard Seline, co-founder and managing director of the Houston-based Resilience Innovation Hub. The innovation hub is a partner in the manufacturing hub.

Seline says the manufacturing hub, with an estimated price tag of $32 million, will directly employ about 60 people. He expects the facility to either generate or “upskill” about 240 off-site jobs.

The manufacturing hub will be built adjacent to the 300,000-square-foot East End Maker Hub, which is opened in Houston’s Second Ward neighborhood two years ago. Seline says five companies already have expressed interest in being tenants at the manufacturing hub, which is set to open by next summer.

“We know that the supply chains keep failing over and over again in regard to responding to and rebuilding after disasters. This is a way to address that,” Seline says of the manufacturing hub.

Aside from the innovation hub and East End Maker Hub, partners in the manufacturing venture are the nonprofit Urban Partnerships Community Development Corp. (UPC) and modular construction company VEMAS. UPC is based in Houston, and VEMAS has a Houston office.

“The Resilience Manufacturing Hub is one of four pillars in UPC’s vision for an Invest Houston strategy to grow our economy from within by directly impacting middle-income employment — vital for the 1 million jobs projected as a gap in greater Houston’s long-term competitiveness,” says Patrick Ezzell, president and chairman of UPC and founder of the East End Maker Hub.

The manufacturing hub will work hand in hand with the innovation hub. The innovation hub assesses and addresses risks triggered by climate-produced, manmade, pandemic-related and cybersecurity threats. Hub participants work on innovations aimed at alleviating these risks.

In 2012, the National Academy of Sciences defined resilience as “the ability to prepare and plan for, absorb, recover from, and more successfully adapt to adverse events.” Those events include hurricanes and floods.

The resilience movement got a substantial boost last year thanks to passage of the federal Community Disaster Resilience Zones Act. The law allows for designation of resilience zones in communities that are at high risk of natural disasters and have limited resources. These zones will qualify for federal funding earmarked for resilience efforts.

Harris County scores nearly 98 out of 100 on the National Risk Index, generated by the Federal Emergency Management Agency (FEMA), putting it into the “very high” risk category for natural hazards.

Yet Harris County ekes out a score of 12.73 out of 100 for community resilience, landing it in the “very low” category. This means the county has a poor ability to prepare for natural hazards, adapt to changing conditions, and withstand and recover from disruptions.

Houston-based biomaterials company raises $1.1M to grow team, build new HQ

money moves

A Houston company that has created a plant-based material that can replace unsustainable conventional leathers and plastics has announced the close of its oversubscribed seed funding round.

BUCHA BIO announced it's raised $1.1 million in seed funding. The round included participation from existing partners New Climate Ventures, Lifely VC, and Beni VC, as well as from new partners Prithvi VC, Asymmetry VC, and investors from the Glasswall Syndicate, including Alwyn Capital, as well as Chris Zarou, CEO & Founder of Visionary Music Group and manager of multi-platinum Grammy-nominated rapper, Logic, the startup reports in a news release.

“I’m excited to back BUCHA BIO’s amazing early market traction," Zarou says in the release. "Their next-gen bio-based materials are game-changing, and their goals align with my personal vision for a more sustainable future within the entertainment industry and beyond.”

The company, which relocated its headquarters from New York to Houston in February, was founded by Zimri T. Hinshaw in 2020 and is based out of the East End Makers Hub and Greentown Houston.

BUCHA BIO has created two bio-based materials using bacterial nanocellulose and other plant-based components. The two materials are SHORAI, which can be used as a leather alternative, and HIKARI, a translucent material that is expected to be formally introduced in November.

The fresh funding will help the company to accelerate its move into the marketplace next year by securing co-manufacturers to scale production. Additionally, the company is growing its team and is hiring for a new supply chain lead as well as some technician roles.

Per the release, BUCHA BIO is working on constructing a new headquarters in Houston that will house a materials development laboratory, prototype manufacturing line, and offices.

BUCHA BIO has the potential to impact several industries from fashion and automotive to construction and electronics. According to the Material Innovation Initiative, the alternative materials industry has seen an increased level of interest from investors who have dedicated over $2 billion into the sector since 2015.

“The time for rapid growth for biomaterials is now," says repeat investor Eric Rubenstein, founding managing partner at Houston-based New Climate Ventures, in the release. "BUCHA BIO's team and technical development are advancing hand in hand with the demands of brand partnerships, and we are excited to support them as they capitalize on this global opportunity.”

Houston bioprinting startup to be acquired for up to $400M

big move

Houston-based Volumetric Biotechnologies has gone from startup to nine-figure acquisition in a mere three years.

Volumetric, which makes 3D-printed human organs and tissues, agreed October 27 to be purchased by publicly traded 3D Systems, a Rock Hill, South Carolina-based company that specializes in 3D technology, for as much as $400 million. The cash-and-stock deal, expected to be completed this year, will provide $45 million at closing and up to $355 million if Volumetric reaches certain benchmarks.

"Volumetric is already successful in its space with innovative light-based bioprinting," says Jeffrey Graves, president and CEO of 3D Systems. "This acquisition and integration of Volumetric into the 3D Systems family advances our commitment to health care."

Founded in 2018, Volumetric is a privately held spin-out of Rice University's bioengineering department. Its co-founders are Jordan Miller, the company's president, and Bagrat Grigoryan, the chief operating officer. Volumetric participated in the San Francisco-based accelerator Y Combinator in 2020. Investors include two health care nonprofits, the Methuselah Foundation and Methuselah Fund.

Miller, an associate professor of bioengineering at Rice University, will join 3D Systems as chief scientist for regenerative medicine, and Grigoryan will come aboard as vice president of regenerative medicine.

In conjunction with the acquisition, 3D Systems and business partner United Therapeutics, based in Manchester, New Hampshire, will conduct R&D for organ and tissue manufacturing at Volumetric's 20,000-square-foot facility in Houston's East End Maker Hub. Last December, Volumetric moved its operations to the hub. The startup produces human organs and tissues like the liver, kidney, pancreas, lung, and heart using a combination of human cells and medical-grade plastics.

"The vital organs inside of the human body are the most complicated structures in the known universe," Miller says in a news release. "Just as a vibrant city needs roads, a vital organ needs vasculature. Our work to date at Volumetric has focused on 3D bioprinting the intricate blood vessel architecture that is crucial for the function of these organs."

Grigoryan says manufacturing human organs represents a "transformative opportunity" to combat organ diseases.

"Broadening our team's ability to deliver on the promise of organ therapy is a win for patients and medical care around the world, as well as Volumetric shareholders who believed in our promise from early phase development," Grigoryan says.

Houston has all the ingredients to thrive as a manufacturing hub, says expert

guest column

Manufacturing is critical to building the economy on both local and national levels.

According to Deloitte and The Manufacturing Institute, 4.6 million U.S. manufacturing jobs will be needed by 2030. The National Association of Manufacturing estimates that each $1 spent in manufacturing adds $2.79 to the economy and each $1 earned in direct manufacturing labor income yields $3.14 in labor income elsewhere. Failing to fill these jobs could cost the U.S. $1 trillion and thwart economic growth.

Manufacturing is a win-win for Houston. With Houston's manufacturing sectors tied to the overall U.S. economy, the Greater Houston area has the opportunity to thrive as a manufacturing powerhouse by returning manufacturing to the U.S.

"Houston is an amazing city with a wide variety of entrepreneurs, inventors and industry specialties. To support these firms, we need tens of thousands of skilled employees in a plethora of manufacturing jobs. On the product side, they include Space, Medical Devices, Robotics, Additive Manufacturing, BioEngineering, and next generation energy devices. From the process side - refined products, chemicals, beverages and plastics," said Michael Holthouse, CEO and founder of Holthouse Foundation For Kids.

In an effort to increase awareness of these advanced manufacturing careers, TXRX East End Maker Hub is hosting Manufacturing Day Houston on Friday, October 1. The event is attracting hundreds of middle- and high-school youth along with their teachers from the Greater Houston area.

EEMH is opening its doors to allow students the opportunity to engage in hands-on experiences, demonstrations, and interact with subject matter experts to learn the latest technologies in Process Manufacturing, Product Manufacturing, Bioengineering, Virtual Reality, Robotics, 3D printing and more. The keynote speaker, Jim "Mattress Mack" McIngvale of Gallery Furniture, will open the event.

Manufacturing Day Houston is a local effort to join National Manufacturing Day and Creators Wanted, both industry initiatives supported by the National Association of Manufacturers and the Manufacturing Institute. Manufacturing Day Houston has been created to reshape the perception of the advanced manufacturing industry and help today's youth understand how they can match their talents with in-demand product and process manufacturing careers that average $87,185 annually.

While attractive, many of these skilled manufacturing jobs go unfilled due to misinterpretations about the industry and educational opportunities. Houston's community colleges and technical programs offer affordable training for these opportunities, which can be completed in two years or less.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”

Baylor College of Medicine received $3.5 million to help hospitals in Texas better care for and diagnose some of the state's most vulnerable patients.

The funds come from the National Human Genome Research Institute for the Making Genomics Accessible to Newborns in Texas, or MAGNET, program. They'll be used to adapt BCM's Consultagene telehealth platform to be used in underserved neonatal intensive care units in West and South Texas, according to a statement.

Families in this region of the state currently can travel up to 300 miles to reach the nearest in-state geneticist, according to MAGNET. The program aims to help close that gap through BCM's established remote consultation service. Investigators also plan to create educational videos in English and Spanish to educate providers and patient caregivers on genetic diagnoses.

“Only 20 years ago, less than 3 percent of genetic conditions in newborns could be molecularly diagnosed,” Dr. Brendan Lee, co-principal investigator and professor and chair of the Department of Molecular and Human Genetics and Robert and Janice McNair Endowed Chair in Molecular and Human Genetics at BCM, says in a statement.
