Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

Houston bio-based materials founder rebrands, evolves future-focused sustainability startup

HOUSTON INNOVATORS PODCAST EPISODE 255

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.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from esports to biomaterials — recently making headlines in Houston innovation.

Zimri Hinshaw, CEO of BUCHA BIO

After raising a seed round of funding, BUCHA BIO is gearing up to move into its new facility. The biomaterials company was founded in New York City in 2020, but CEO Zimri T. Hinshaw shares how he started looking for a new headquarters for the company — one that was more affordable, had a solid talent pool, and offered a better quality of life for employees. He narrowed it down from over 20 cities to two — San Diego and Houston — before ultimately deciding on the Bayou City.

Since officially relocating, Hinshaw says he's fully committed to the city's innovation ecosystem. BUCHA BIO has a presence at the University of Houston, Greentown Labs, and the East End Maker Hub — where the startup is building out a new space to fit the growing team.

"By the end of this month, our laboratories will be up and running, we'll have office space adjacent, as well as chemical storage," Hinshaw says on the Houston Innovators Podcast. Listen to the episode and read more.

For many video games is getaway from reality, but for those with disabilities — thanks to a nonprofit organization —gaming can mean a lot more. On Saturday Dec. 3 — International Day of Persons with Disabilities — from 1 to 9 pm, Easter Seals Greater Houston will be joining forces with ES Gaming for the inaugural Game4Access Streamathon.

Gaming helps enhance cognitive skills, motor skills, improve mental well-being, and can help reduce feelings of social isolation due to the interactive nature of playing with others.

“This is really a unique way for (people) to form a community without having to leave their house, and being part of an inclusive environment,” says Kelly Klein, development director of Easter Seals Greater Houston. ”The adaptive equipment and specialized technology just does so many miraculous things for people with disabilities on so many levels — not just gaming. With gaming, it is an entrance into a whole new world.” Read more.

Levit Green, a 53-acre mixed-use life science district next to the Texas Medical Center and expected to deliver this year, has leased approximately 10,000 square feet of commercial lab and office space to Sino Biological Inc. The Bejing-based company is an international reagent supplier and service provider. Houston-based real estate investor, development, and property manager Hines announced the new lease in partnership with 2ML Real Estate Interests and Harrison Street.

“Levit Green was meticulously designed to provide best-in-class life science space that can accommodate a multitude of uses. Welcoming Sino Biological is a testament to the market need for sophisticated, flexible space that allows diversified firms to perform a variety of research,” says John Mooz, senior managing director at Hines, in a press release. “Sino is an excellent addition to the district’s growing life science ecosystem, and we look forward to supporting their continued growth and success.” Read more.Read more.

Houston sustainable materials startup moves into new facility, plans to hire

HOUSTON INNOVATORS PODCAST EPISODE 161

After raising a seed round of funding, an alternative materials startup is gearing up to move into its new facility.

BUCHA BIO, a climatetech company that's creating sustainable materials to replace plastics and leather for the fashion industry and beyond, closed its most recent round of funding at $1.1 million in September. Now, the company is full speed ahead getting ready to move into a larger office and lab space this month while hiring within technical roles, supply chain, quality control scientists, and more to make sure BUCHA BIO is ready to scale.

"That's the biggest deployment of capital — making sure we have the team that can scale this and so we can set up the logistics needed," CEO Zimri T. Hinshaw says on this week's episode of the Houston Innovators Podcast. "It's not all fun innovative materials — it's also really fun international supply chain logistics. Some of these things we don't always talk about are equally important to make sure we are creating a product that has the potential to displace plastic and leather at scale."

Hinshaw shares on the podcast how his technology takes the raw material from bacterial and plant-based ingredients — basically a thick malleable substance — and turns it into a durable sheet of material that can be used in fashion, but also automotive and energy-adjacent industries.

BUCHA BIO was founded in New York City in 2020, but after the company participated in SOSV's IndieBio program, Hinshaw shares how he started looking for a new headquarters for the company — one that was more affordable, had a solid talent pool, and offered a better quality of life for employees.

"Manhattan is a notoriously difficult place to live and work — and to grow a company like this. It just came to a point where we couldn't afford to give the talent a high quality of life, and that's important to me as a leader," Hinshaw says. "We couldn't afford the space. ... That was the tipping point for us."

Hinshaw says he looked at over 20 cities closely — Austin; Akron, Ohio; Dallas; Miami; and more. He narrowed it down to San Diego and Houston, before ultimately deciding on the Bayou City.

Since officially relocating, Hinshaw says he's fully committed to the city's innovation ecosystem. BUCHA BIO has a presence at the University of Houston, Greentown Labs, and the East End Maker Hub — where the startup is building out a new space to fit the growing team.

"By the end of this month, our laboratories will be up and running, we'll have office space adjacent, as well as chemical storage," Hinshaw says. "We aren't manufacturing onsite — we're prototyping and improving manufacturing onsite."

The technology BUCHA BIO uses to produce its materials is called an extruder, and the company has its own smaller scale model within its facilities. Hinshaw says the process includes outsourcing the larger scale process at existing facilities.

After fully moving in and hiring the new team members the company needs at this phase of scaling, Hinshaw says he'll execute on his current plan to raise more funding from investors.

"As of right now, we are looking to catch up to the competition and to be a major player," Hinshaw says, adding that, as of now, he's aiming for a $10 million series A round. "We're breaking out, and this next round is going to prove that."

Hinshaw shares more about his game plan for BUCHA BIO and his passion for helping to make Houston a leader within the sustainability space on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Overheard: Why these 3 startups relocated to Houston

eavesdropping at the houston innovation awards gala

Houston is attracting more and more businesses big and small, old and new. So much that it seemed worthy of an award for the Houston Innovation Awards Gala.

The awards event, which is on November 9 and hosted by InnovationMap and Houston Exponential at the Ion, is honoring five finalists selected by judges — and naming one winner — who have recently relocated or significantly expanded to Houston.

Here's why three of these New to Hou finalists have committed to Houston.

"The move to the Houston area allowed us to be much closer to our strategic partners, customers and suppliers. We are also impressed by the vast talent pool in the area. Houston has a highly skilled workforce with diverse experiences, particularly in oil and gas, petrochemicals, and a broad range of technical areas."

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."
