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 investor outlines how rare VCs are in Houston — and how to find them

guest column

As a venture capitalist and former startup founder living in Houston, I get asked a lot about the best way to find and connect with a venture capitalist in Houston. My usual advice is to start with a list, and reach out to everyone on that list. But no one has a comprehensive list. In fact, VCs are such a quiet bunch that I’ve yet to meet someone who personally knows everyone on this proverbial list.

So, I got together with a couple of VC friends of mine, and we put together our own Houston venture capitalist list.

There are, by our count, 11 active venture capital funds headquartered in Houston of any size and type, and outside of corporate venture capital and angel investors, there are 30 total venture capitalists running funds.

Houston has always been quite thin on the VC fund front. I’ve jokingly introduced myself for a while as “one of the 13 venture capitalists in Houston.”

Let’s put this scale in some brutal perspective. With 7.2 million people in the Greater Houston Metro Area, the odds of finding a partner level active venture capitalist in Houston is about 1 in 240,000, if you take a most expanded definition of venture capitalist that might come down to 1 in 100,000. We’re the fifth largest metropolitan area in the country with a tremendous economic engine; there is a ton of capital in Houston, but it’s residing in things like institutional fixed income and equities, real estate, wealth management, corporate, private equity, family office, energy and infrastructure Basically, mostly everywhere but in venture capital funds for tech startups.

By comparison, there are almost as many Fortune 500 CEOs in Houston — 24, by our count — as venture capitalists and fewer venture capitalists than Fortune 1000 CEOs, of which there are 43. That means running into a VC in the checkout line at HEB is about as rare as running into the CEO of CenterPoint, ConocoPhillips, or Academy. In fact, as there are 115 cities in the Greater Houston area, you are three times more likely to be a mayor in Greater Houston Area than a partner at an investor at a VC firm, and more likely to be a college or university president. While we’re at it, you’re 400 times more likely to be a lawyer, 250 times more likely to be a CPA, and over 650 times more likely to be a medical doctor.

Our 30 venture capitalists in the Greater Houston Area are spread across 20 firms and all major venture sectors and stages. Venture capitalist is defined for this list as a full time managing director or partner-level investment professional actively running a venture capital fund with limited partners, currently investing in new venture capital deals from their fund from seed to growth stage, and residing in the Greater Houston Metro area.

To get to 31 we added in a couple of people running venture set asides for PE funds, and a number who work from Houston for funds with no office here. We excluded CVCs, as the decision making is more corporate than individual and rarely includes the committed fund and carried interest structure that defines venture capital, and excluded professionals at angel networks, accelerators, and seed funds that provide investment, but don’t manage conventional venture capital funds, as well as PE funds that do the occasional venture deal. We might be able to triple the number if we include venture capitalists at any professional level, and add in those professionals at PE and angel and seed funds, and corporate venture capital teams who are actively investing. But we’ll get to those other sources of funding in the next list.

The 11 venture capital funds headquartered in Houston are: Mercury, Energy Transition Ventures (my fund), Montrose Lane (formerly called Cottonwood), Texas Medical Center Venture Fund, Artemis, New Climate Ventures, Fitz Gate Ventures, Curate Capital, Knightsgate Ventures, Amplo Ventures,and First Bight Ventures.

Another half a dozen firms have a partner level venture capital investor here, but are headquartered elsewhere: Energy Innovation Capital, Decarbonization Partners, 1984 Ventures, Altitude Ventures, Ascension Ventures, Moneta Ventures, and MKB & Co. Two others, CSL Ventures and SCF Partners, are local private equity funds with a venture capital partner in Houston and a dedicated allocation from a PE fund.

Culling these for partner or managing director level currently in Houston, in alphabetical order by first name, LinkedIn profile and all.

Abhinav Jain, CSL Ventures
Aziz Gilani, Mercury Fund
Blair Garrou, Mercury Fund
Brent Kelton, Moneta Ventures
Carrie Colbert, Curate Capital
David Hayes, Decarbonization Partners
Diana Murakhovskaya, Artemis Fund
Don Kendall, New Climate Ventures

We may have missed a couple of VCs hiding in plain sight, as venture capital is a pretty dynamic business.

VCs are just rare. And yes, perhaps more rare in Houston than in California. Something less than 1 in 100 VCs in the country live in Houston. Across the US there are somewhere around 1,000 to 2,000 active venture capital firms, and maybe another 1,000 to 2,000 active US based CVCs — so, plus or minus maybe at most 4,000 to 5,000 currently active partner level venture capitalists in the country excluding CVC professionals (active VCs and VC funds are really hard to count).

Perhaps in the most stunning statistic, the 7,386 elected state legislators in the US today outnumber the total number of American venture capitalists. Luckily for startup founders, the venture capitalists are more likely to return your phone call.

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.”

A sustainable fashion company has relocated to Houston. Bucha Bio, founded in 2019, creates in textiles and composite materials made from bacterial nanocellulose, a much more sustainable materials production, that can be used instead of animal leather, polyurethane, latex, vinyl, epoxy, and more. The company announced in a press release today that it's moving from New York City and opening a next-gen materials headquarters at the East End Maker Hub. Bucha Bio has also been accepted as a member company at Greentown Labs.

According to the release, over 20 locations were considered, and Houston stood out for its hiring potential, local universities, Texas's business-friendly regulation, and more.

“We’ve signed on senior scientists and their experiences from the oil and plastic industry are perfectly suited to biomaterials,” says Zimri T. Hinshaw, CEO of Bucha Bio, in the release. Click here to read more.

Climate tech investor says Houston has a multifaceted role to play in the energy transition

houston innovators podcast episode 122

If the city of Houston wants to maintain its moniker of Energy Capital of the World, it has make strides within the energy transition — and that needs to be accomplished in a myriad of ways.

"Houston's role (within the energy transition) is multifaceted," says Eric Rubenstein, founding managing partner of New Climate Ventures, on this week's episode of the Houston Innovators Podcast.

"We have a talent pool here that fits pretty well in climate tech, alternative materials, and other spaces," he continues. "We have a customer base here that is going to adopt these new technologies."

The fact that Houston's major energy companies — of which there are many in town — will be the customers of emerging clean energy technologies positions the city as a hub for attracting innovative startups. Just last week, Bucha Bio, one of NCV's portfolio companies expanded into Houston. The New-York founded startup creates in textiles and composite materials made from bacterial nanocellulose, a much more sustainable materials production, that can be used instead of animal leather, polyurethane, latex, vinyl, epoxy, and more.

Rubenstein says Bucha Bio narrowed down its options to San Diego and Houston, before ultimately deciding on the Bayou City for its talent pool. The company, which is a member of Greentown Houston, is now based out of the East End Maker Hub.

"As these technologies are being spun out of labs, Houston has become a destination for these companies," Rubenstein says. "Bucha Bio isn't an irregular occurrence these days."

The missing piece of the puzzle is still venture dollars — and Rubenstein is on a mission to move that needle. This year, NCV is focused on closing its fund and deploying capital into early-staged climate tech companies.

"Our goal is really to watch for transformational change in the industries we're investing in," he says. "We're really excited about the technologies in the space and will continue looking for what's to come."

Rubenstein shares more about New Climate Ventures and the trend that is impact investing on the podcast. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Sustainable biomaterials startup expands to Houston

new to hou

A New York-founded biomaterials company has announced the opening of operations in Houston after research found the region's workforce “perfectly suited to biomaterials.”

Bucha Bio, founded in 2019, creates in textiles and composite materials made from bacterial nanocellulose, a much more sustainable materials production, that can be used instead of animal leather, polyurethane, latex, vinyl, epoxy, and more. The company announced in a press release today that it's moving from New York City and opening a next-gen materials headquarters at the East End Maker Hub. Bucha Bio has also been accepted as a member company at Greentown Labs.

According to the release, over 20 locations were considered, and Houston stood out for its hiring potential, local universities, Texas's business-friendly regulation, and more.

“We’ve signed on senior scientists and their experiences from the oil and plastic industry are perfectly suited to biomaterials,” says Zimri T. Hinshaw, CEO of Bucha Bio, in the release.

One of these new local hires was Alex Kalin, who joined the company as senior materials scientist from Halliburton.

“It’s a great time to be involved in developing sustainable materials technologies," Kalin says in the release. "Having the opportunity to make a positive impact on the environment was a key factor for me joining Bucha Bio.”

Houston's chemical plant carbon footprint includes 56 gigatons tons of carbon that will be produced from now until 2050 — this number could be shrunk with sustainable alternatives like the one Bucha Bio provides. This potential has been recognized by Greentown Labs.

“Bringing world class energy transition companies like Bucha Bio to Houston is a win-win; not only is Bucha positioned to tap into a diverse talent pool from Universities such as Rice, University of Houston, and Texas A&M, but a wealth of extant talent which is looking to transition their careers; Zimri and his team bring more than technology to Houston, they bring the knowhow, vigor, and network it takes to build meaningful disruptive technology company," says Jason Ethier, senior director of memberships at Greentown Houston.

Last fall, Bucha Bio raised $550,000 in funding led by Houston-based New Climate Ventures with support from SOSV’s IndieBio.

“Bucha Bio’s move to Houston marks a milestone for their ability to keep up with the growing demand for their products and for our shared vision of a clean environment for generations to come," Eric Rubenstein of NCV says.

Biosciences startup becomes Texas' first decacorn after latest funding

A Dallas-based biosciences startup whose backers include millionaire investors from Austin and Dallas has reached decacorn status — a valuation of at least $10 billion — after hauling in a series C funding round of $200 million, the company announced this month. Colossal Biosciences is reportedly the first Texas startup to rise to the decacorn level.

Colossal, which specializes in genetic engineering technology designed to bring back or protect various species, received the $200 million from TWG Global, an investment conglomerate led by billionaire investors Mark Walter and Thomas Tull. Walter is part owner of Major League Baseball’s Los Angeles Dodgers, and Tull is part owner of the NFL’s Pittsburgh Steelers.

Among the projects Colossal is tackling is the resurrection of three extinct animals — the dodo bird, Tasmanian tiger and woolly mammoth — through the use of DNA and genomics.

The latest round of funding values Colossal at $10.2 billion. Since launching in 2021, the startup has raised $435 million in venture capital.

In addition to Walter and Tull, Colossal’s investors include prominent video game developer Richard Garriott of Austin and private equity veteran Victor Vescov of Dallas. The two millionaires are known for their exploits as undersea explorers and tourist astronauts.

Aside from Colossal’s ties to Dallas and Austin, the startup has a Houston connection.

The company teamed up with Baylor College of Medicine researcher Paul Ling to develop a vaccine for elephant endotheliotropic herpesvirus (EEHV), the deadliest disease among young elephants. In partnership with the Houston Zoo, Ling’s lab at the Baylor College of Medicine has set up a research program that focuses on diagnosing and treating EEHV, and on coming up with a vaccine to protect elephants against the disease. Ling and the BCMe are members of the North American EEHV Advisory Group.

Colossal operates research labs Dallas, Boston and Melbourne, Australia.

“Colossal is the leading company working at the intersection of AI, computational biology, and genetic engineering for both de-extinction and species preservation,” Walter, CEO of TWG Globa, said in a news release. “Colossal has assembled a world-class team that has already driven, in a short period of time, significant technology innovations and impact in advancing conservation, which is a core value of TWG Global.”

Well-known genetics researcher George Church, co-founder of Colossal, calls the startup “a revolutionary genetics company making science fiction into science fact.”

“We are creating the technology to build de-extinction science and scale conservation biology,” he added, “particularly for endangered and at-risk species.”

Houston investment firm names tech exec as new partner

new hire

Houston tech executive Robert Kester has joined Houston-based Veriten, an energy-focused research, investment and strategy firm, as technology and innovation partner.

Kester most recently served as chief technology officer for emissions solutions at Honeywell Process Solutions, where he worked for five years. Honeywell International acquired Houston-based oil and gas technology company Rebellion Photonics, where Kester was co-founder and CEO, in 2019.

Honeywell Process Solutions shares offices in Houston with the global headquarters of Honeywell Performance Materials and Technologies. Honeywell, a Fortune 100 conglomerate, employs more than 850 people in Houston.

“We are thrilled to welcome Robert to the Veriten team,” founder and CEO Maynard Holt said in a statement, “and are confident that his technical expertise and skills will make a big contribution to Veriten’s partner and investor community. He will [oversee] every aspect of what we do, with the use case for AI in energy high on the 2025 priority list.”

Kester earned a doctoral degree in bioengineering from Rice University, a master’s degree in optical sciences from the University of Arizona and a bachelor’s degree in laser optical engineering technology from the Oregon Institute of Technology. He holds 25 patents and has more than 25 patents pending.

Veriten celebrated its third anniversary on January 10, the day that the hiring of Kester was announced. The startup launched with seven employees.

“With the addition of Dr. Kester, we are a 26-person team and are as enthusiastic as ever about improving the energy dialogue and researching the future paths for energy,” Holt added.
