A Houston-based next-gen material startup has revealed a new strategic partnership.

Rheom Materials, formerly known as Bucha Bio, has announced a strategic partnership with thermoplastic extrusion and lamination company Bixby International, which is part of Rheom Material’s goal for commercial-scale production of its novel biobased material, Shorai.

Shorai is a biobased leather alternative that meets criteria for many companies wanting to incorporate sustainable materials. Shorai performs like traditional leather, but offers scalable production at a competitive price point. Extruded as a continuous sheet and having more than 92 percent biobased content, Shorai achieves an 80 percent reduction in carbon footprint compared to synthetic leather, according to Rheom.

Rheom, which is backed by Houston-based New Climate Ventures, will be allowing Bixby International to take a minority ownership stake in Rheom Materials as part of the deal.

“Partnering with Bixby International enables us to harness their extensive expertise in the extrusion industry and its entire supply chain, facilitating the successful scale-up of Shorai production,” Carolina Amin Ferril, CTO at Rheom Materials, says in a news release. “Their highly competitive and adaptable capabilities will allow us to offer more solutions and exceed our customers’ expectations.”

In late 2024, Rheom Materials started its first pilot-scale trial at the Bixby International facilities with the goal of producing Shorai for prototype samples.

"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," founder Zimri Hinshaw previously told InnovationMap.

Listen to Hinshaw on the Houston Innovators Podcast episode recorded in October.

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes an alternative materials founder, a Houston ecosystem builder, and the city's richest billionaire.

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." Read more.

What is your purpose in life? One Houstonian is asking that question of his fellow entrepreneurs all across town.

Joey Sanchez founded Cup of Joey, a weekly meetup opportunity for innovators, business leaders, and the whole Houston community. The events are a place not only to share a cup of coffee but also their very own mission in life.

It all started in 2021 at the Houston Tech Rodeo, an initiative from Houston Exponential, where Sanchez worked as a director of corporate engagement. Texas had just opened social distancing in public events since the beginning of the COVID-19 pandemic, and Sanchez was finding ways to reconnect the Houston community.

‘We thought what better way than over a cup of coffee?” Since then, Sanchez has connected thousands of people based on purpose every Friday for the past three and a half years. Read more.

A dozen of Houston's illustrious billionaires have made the cut on the new Forbes 400, a list of the 400 richest people in the United States for 2024.

Houston hospitality king and Rockets owner Tilman Fertitta is the 12th richest Texan and the 99th richest person in the United States, according to the new Forbes 400 list, released October 1.

Forbes estimates Fertitta's net worth in 2024 as $10.1 billion, which has steadily climbed from his 2023 net worth of $8.1 billion. Fertitta, 67, purchased the Houston Rockets in October 2017 for $2.2 billion. The billionaire also owns Texas-based hospitality and entertainment corporation Landry's. In 2019, Fertitta embarked on a new venture as an author. Read more.

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."

— Jay Manouchehri, CEO of Fluence Analytics, which relocated from Louisiana to Stafford last year, just outside of Houston. "We have been able to engage very actively with many customers since the move and also have developed valuable supplier relationships."

"In 2019, Chevron and EIC (both Houston based) became investors and we already had a lot of US clients, so we wanted to create a Houston footprint."

— John van Pol, co-founder and CEO of INGU, which opened its new Houston office in 2021. Van Pol adds that the pandemic delayed their expansion initially.

"Houston has a quickly-growing biotechnology sector and already has existing oil and gas talent, making it an ideal place to find the people we need to grow our business."

Here's the income it takes to live comfortably in Houston in 2026

Money Talk

2026 report analyzing how much it costs to live "in sustainable comfort" in the biggest U.S. cities has found Houston residents have the 11th lowest salary requirement to live a comfortable life in 2026.

SmartAsset's annual report found single adult residents in Houston need to make $89,981 a year to qualify as "financially stable." Compared to last year, single Houstonians needed to make $83 more to live comfortably in the city.

Families with two working parents and two children need to make a household income of $204,672 to have a financially stable life in Houston, the report found. That's almost $2,000 less than what families needed to make last year.

To determine the rankings, SmartAsset's analysts examined 100 of the largest U.S. cities and used the latest cost of living data – such as the costs for housing, food, transportation, and income taxes where applicable – from the MIT Living Wage Calculator for childless individuals and for two working adults with two children.

For the purpose of the study, the 50/30/20 budgeting strategy was used to determine "comfortable lifestyle" costs for both individuals and families: 50 percent of income to cover needs and living expenses, 30 percent for "wants," and 20 percent for savings or paying down debt.

Here's breakdown of a Houston resident's comfortable lifestyle based on SmartAsset's findings:

  • $44,991 dedicated to needs and living expenses
  • $26,994 dedicated to wants
  • $17,996 dedicated to savings or debt repayment

This is SmartAsset's interpretation of a comfortable lifestyle for families of four:

  • $102,336 dedicated to needs and living expenses
  • $61,402 dedicated to wants
  • $40,934 dedicated to savings or debt repayment
SmartAsset said single individuals and families should compare the fluctuating local cost of living and their long-term goals to fully "understand the context" of their respective household incomes. But it's worth pointing out that a financially stable life in Houston isn't quite attainable for many residents: The city had a median household income of $64,361 in 2024, according to the U.S. Census Bureau.

Comfortable salaries in other Texas cities

Elsewhere in Texas, the report found that families in the Dallas-Fort Worth suburbs Frisco and McKinney "are closest to a comfortable salary."

"In Frisco, the median household earns $145,444 – substantially higher than the national median of $83,730," the report's author wrote. "This figure also accounts for 63.1 percent of the $230,464 income a family of four in Frisco needs to live comfortably. In McKinney, TX, the $124,177 median household income accounts for 53.9 percent of the $230,464 needed."

Both cities also tied with Plano for the 29th highest salary needed nationally to live comfortably in 2026. Single adults living in these cities need to make $109,242 a year to live a financially stable life this year.


On the opposite end, San Antonio has the lowest salaries needed to live comfortably in the U.S. Single adults only need to make $83,242 a year, and $192,608 for families of four.

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization
