EnergyTech Cypher has opened applications for its second Liftoff fundraising program.

Applications close May 20 for the 10-week virtual fundraising sprint. The program is geared toward energy and climatech founders preparing to raise their first institutional round. It will cover fundraising requisites, like pitch materials, term sheet negotiation and round closing, according to a release from EnergyTech Cypher.

The program kicks off June 1 and runs every Monday from 1-3 p.m. CST. It will conclude with an in-person capstone simulation in Houston on August 3, where founders will work to close a mock round.

Jason Ethier, EnergyTech Cypher founder and CEO, will lead the program with Payal Patel, an EnergyTech fellow and entrepreneur in residence.

The program is available through Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders. Users must have a Cephyron Boost membership to participate in the Liftoff program.

The Cephyron IRM app recently went live and is available to founders at any point in their fundraising process, according to the news release. The platform aggregates investor data, tracks market signals and delivers curated weekly recommendations.

EnergyTech Cypher launched Liftoff last year. The inaugural cohort included 19 startups, including Houston-based AtmoSpark Technologies, The Woodlands-based Resollant and others. Each participant closed at least one fundraising deal, according to EnergyTech Cypher.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. It also launched its CoPilot accelerator in 2025. The inaugural group presented its first showcase during CERAWeek last month.

EnergyTech Cypher's annual Pilotathon Pilot Pitch and Showcase applications also opened this month. Find more information here.

How this startup leveraged friends and family investment for an oversubscribed round of funding

guest column

When I wrote about fundraising early this year, I knew that I would be raising a round shortly, but had no idea I would be doing it in a changed COVID-19 world. I have experienced two unexpected recessions as an entrepreneur — in 2001 and 2008 — and each time causing huge struggles for entrepreneurs to raise funds. That is when I developed the mindset of acting like a desert rat, surviving with little help, learning to tap into the resources around you to survive and even thrive. Little did I know what was coming in March when the COVID-19 shutdown started.

Solenic Medical Inc. is a medical device company developing an innovative non-invasive treatment for infected metallic implants in the body. Using technology invented at the University of Texas Southwestern, Solenic will leverage the unique properties of alternating magnetic fields generated from external coils to eradicate biofilm on the surface of medical implants.

This non-invasive treatment addresses a major complication of various surgeries, such as knee and hip replacements, as well as in trauma related implants such as plates and rods. There are certainly challenges to fundraising for medical device companies, but each technology arena has its own challenges that I won't go into here.

The Solenic Medical team knew we needed to raise a round early this year, building upon the progress achieved since our founding investment in early 2019. The question was what type and size a round to raise.

We knew we were close to taking some valuable steps, but needed a just a little more time and funding to get there, at which point we figured we would be able to step up our valuation greatly. We decided on a modest $500,000 convertible note round, to help us accomplish at least a portion of the following items:

  • Recruit a reputable outside board member
  • Complete a planned large animal study stepping up from previous mice studies
  • Complete submission of a Breakthrough Device application to the FDA
  • Close our $1.3 million NIH grant and/or other non-dilutive funding
  • Fine tune simulation approaches to optimize the transducer design
  • File new intellectual property

We knew that some combination of these would occur in the succeeding months and would make it easier for Solenic to raise further funds.

The first domino was the on-boarding of an experienced technology executive from Virginia to join our board. The large animal study was delayed when the COVID-19 shutdown started, but our Breakthrough application and the grant application review started as the team went into virtual work mode. Progress was made on the simulations and drafting our next patent. The dominos were starting to fall in spite of the shutdown.

My philosophy was to treat the round as five different type of efforts, in pretty much five equal portions.

  • The first 20 percent in a round is always the hardest, even in closely held friends and family round. The first check regardless of size is always hard as often investors very interested in the round will wait for others to move first.
  • The second 20 percent is not much easier, still requiring a leap of faith by the investor.
  • The magic starts happening at 40 percent, where momentum picks up as you approach halfway and beyond.
  • At 60 percent you reach real momentum, where those investors who may have been waiting to move for a while now start moving.
  • At 80 percent you pick up investors who move quickly worried about missing out before the round closes.
  • With luck, you get enough momentum to oversubscribe the round and have to make the call to go beyond your target funds. For a quick hint on where I standard at that point, there's a saying that you never turn down money.

It was strange picking up the fundraising activity via zoom meetings, and it got off to a slow start as the initial circumstances of the new COVID-19 world settled in. Following my own advice from the January article, I started strategizing my communications, who might be the first check and first movers in first 20 percent, then the next 20 percent and so forth. For a friends and family round you start with your board as champions for the round, founders and management. No one is likely to be more committed and likely to get things started generally, much less in unusual financial times like a pandemic shutdown.

With an institutional co-founder like VIC Technology Venture Development and a passionate board we were able to jumpstart the round the round with $110,000 in commitments. This was quickly followed $100,000 from friends and family of board or management team members. Note that "quickly" in a pandemic was three months that in normal times might have taken only a month or so. Now that we had crossed that magic 40 percent hurdle, things started picking up speed, where members of the VIC Investor Network added individual investments totaling $140,000 to pass the next hurdle of 60 percent within another six weeks of individual presentations and discussions.

Momentum accelerated with friends and family and management team members stepping up to get us to 80 percent within few weeks. At the time of this article we are over-subscribed with more decisions to come. That is a great problem to have as things really picked up speed recently.

Though the final tally is to be determined the mix for this friends and family round looks to be pretty typical to past experiences

  • Board & Management – 27 percent
  • Family – 27 percent
  • Friends – 22 percent
  • Others – 25 percent

Because of the shutdown, this pandemic round has been unusual and at times frustrating, with some highly vocal and interested prospects going strangely silent as soon as the shutdown started, while others moved more slowly than originally expected. Regardless of how things transpired, it turned out largely familiar. As usual, the people you know the best and that know and trust you the most are the ones that are mostly likely come through for you. Building your network to increase the size of that pool is what you do far before a round starts.

Later rounds will be quite different, but the same 20 percent momentum stages will apply. It's a matter of building and nurturing a network of prospects in advance. Larger rounds involve an "institutional" friends and family network that you have known for a while. That work begins long before you start developing them as prospect for an open investment round. By the time this article is published, we expect to have the final funds of this round in the bank but have already started building relationships for the next round. It never stops, but in some ways that is the fun part of it to meet new people to share your startup's story.

Finding funding might be harder during the pandemic. But there are some startups thinking outside the box to attain theirs. Miguel Tovar/University of Houston

How Houston startups can find funding in the age of coronavirus

Houston voices

Almost eight months in to the pandemic and many startups are still fighting to survive. Finding funding has become harder in an era the New York Times calls "The Great Unwinding." But not every startup is succumbing to a bleak fate. Some have shown unique strategies for attaining funding. Here, we'll delve into a few examples of startup companies whose founders have managed to snag funding and stay afloat amid the crashing waters of coronavirus.

Government contracts

Payam Banazadeh, CEO of Capella Space, told Graham Winfrey, senior technology editor for Inc., that it would behoove tech startups to look into acquiring government contracts if possible. His Silicon Valley-based satellite communications startup snagged a lucrative government contract with the Department of Defense. "The government seeks startups that are doing unique things. If they find a product they like, they're going to pursue it. Government contracts help raise additional funding while also de-risking companies in the eyes of investors," Banazadeh said.

Funding conversations matter

Nesh is a company based in Houston that acts as a smart assistant for the energy industry. The startup spent the pandemic engaged in conversations with potential investors. "It's easier to talk to investors at this time. We've had more conversations in the past few months than all of 2019, but nobody is willing to write checks just yet," said Sidd Gupta, founder of Nesh, to Crunchbase News, a tech startup-centric outlet.

The Houston-based company also pivoted by expanding into other oil and gas areas like renewables. Nesh even decided to make its platform accessible free of charge during the shutdown.

Take matters into your own hands

Laally is a breastfeeding assistance device company. During their funding strategizing, they examined all the usual funding avenues: VC, angels, debt, non-profit and potential partnerships with bigger entities. Most of these sources asked for proof of concept and a proven history of solid sales before even thinking of putting money on the table.

Well, that wasn't possible for founders Max and Kate Spivak. They decided to go it alone. Self-funding. "As a family and rookie entrepreneurs, we made the decision to put our money in the balance and hire a partner for the tech part of the business," Max Spivak said told Crunchbase News.

"Even when things got rough as the pandemic worsened, and they did get very rough for us, we didn't have pressure from investors to liquidate assets or investors demanding their money back. That's because we were our own funders," said Kate Spivak.

Creativity can conquer COVID-19

Sometimes adversity is the mother of creativity. These three startup founders stepped outside the box of traditional funding strategies. They discovered ways to change their companies and attain funding during a pandemic that has its foot on the neck of the economy.

Thanks to people like Sidd Gupta, Payam Banazadeh, and the Spivaks, startup founders have a better idea of what they need to do for their startups to live another day. For their companies to see a light at the end of an 8-month long tunnel. The pandemic might have our faces covered, our friends at arm's length, and our jobs in limbo. But it cannot strip away the power of human ingenuity, innovation, and creativity. The founders named above are walking proof.

From debt and equity funds to crowdfunding and angel investment, here's what you need to know about the fundraising world from an expert who's in it. Getty Images

Houston entrepreneur gives his advice on navigating the evolving fundraising process

know before you grow

New businesses face many challenges when getting started, but perhaps none are as challenging and intimidating as how to secure the funding needed to start and grow your business.

Funding options have evolved considerably over the past several years, providing business owners with more choices than ever to fund their business. Founders should not just think about selecting one option but how to combine multiple options into a funding strategy that best suits their business needs.

Over 600,000 new businesses are started in the United States each year, and even with more fundraising options, we are increasingly seeing businesses struggle to get funded, so businesses need to be smart about putting together a funding strategy.

The traditional way to fund a business
With that piece of advice out of the way, there are two primary categories of capital: debt and equity. For your business, debt options may include personal loans, business loans, asset-based loans, revenue participation notes and factoring (where you sell your receivables at a discount in order to collect cash now).

Debt is great as it means you're not giving away equity, but, at the same time, the loan must eventually be paid back (with interest) and some businesses such as technology start-ups may not generate the cash flow needed to make this happen from day one. Loans can also be difficult to access or may require the business owner to put up a personal guarantee, although there are organizations that facilitate this such as Small Business Association. If this is the best route for your business, take the time to find the right lending organization.

Equity options include common stock and preferred stock, as well as convertible note instruments that are initially treated as debt but "convert" to equity at a future financing event. Unlike traditional equity, convertible note instruments allow you to delay establishing a valuation for your business, which can be challenging for startups. SAFE (Simple Agreement for Future Equity) and KISS (Keep It Simple Securities) Notes are emerging securities which are less frequent but are seen as more Founder friendly and are similar in some ways to convertible notes.

There are a lot of business owners that are cautious of giving away equity (and rightly so) but with the right advice on structuring securities and valuation, this can be a great source of capital, as well as knowledge and support if you find the right investors and partners.

Sources of funding for both debt and equity include friends, family, banks, angel investors, venture capital, private equity, and organizations such as the Small Business Association. The accessibility of these various options will depend on the maturity of your business, your industry and the needs of your company. Often, early-stage companies may source "seed" funding from friends, family, and angel investors, while venture capital, private equity, and debt become increasingly accessible at later stages as revenues grow.

How is funding changing?
Options for funding a business and investing have evolved considerably in recent years. Crowdsourcing, which can be defined as the process of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, and especially from an online community, has taken the world by storm. Companies such as Uber, AirBnb, and Grubhub all leverage "the crowd" to provide a service.

Crowdsourcing has made its way to finance as well, where companies such as GoFundMe and KickStarter have provided new tools to fund charitable causes and projects. The Jumpstart Our Business Startups Act (JOBS Act) of 2012 set in motion a series of regulatory changes that allowed anybody (not just high wealth individuals) to invest in private businesses and provided crowdfunding as an option to raise capital for small businesses.

Online crowdfunding portals such as LetsLaunch, SeedInvest, and WeFunder offer both debt and equity options for investors to invest in your business. Not only can this be a great way to build up a loyal customer base, test your product and get some great marketing exposure but it can also be a great way to supplement the traditional funding strategies mentioned above.

However you choose to fund your business, take the time to work through the options (both traditional and emerging) and find the right option or combination of options to meet your business needs.

Houston fundraising platform launches for the next generation of investors

Future funders

Millennials are expected to exceed the Baby Boomer generation for the United States' largest living adult generation this year, and this massive population of people have a completely different approach to investing.

Nick Carnrite saw that Millennials were to a point where they had extra income, but when he looked at the statistics, he noticed they aren't buying houses for the most part and were turned off of the stock market. There was a huge amount of stranded capital, and he wanted to figure out how to get that invested into businesses.

"The younger generation isn't interested in typical investing, but they are absolutely interested in supporting their community and the businesses in it, especially if the investment lets them experience the business and come along for the ride if it works," Carnrite, who is the co-founder and CEO of LetsLaunch, says.

Houston-based LetsLaunch is a new investment platform that launched December 28, though has been in the works since January 2018. The site works, in many ways, like a crowdfunding site, only investors receive equity. Due to regulations, investment campaigns max out at around a million dollars.

In the past, entrepreneurs have had to seek out major investors through venture capitalists or large funds, since taking smaller investments is tedious and almost more trouble than its worth. However, LetsLaunch provides a platform where smaller investments are streamlined and encouraged.

"Our goal in all of this is just to take a complicated process and make it simple, the same way Turbotax takes something awful like taxes and makes it simple, we are trying to do that with investing," Carnrite says.

Investors don't have to be accredited or invest a certain amount of money — something that for so long has hindered startups' ability to raise money.

"For whatever reason, we've decided to alienate about 95 percent of Americans as far as being able to invest in private businesses," Carnrite says. "Finally, we're at the point where all of that capital that was stranded and not allowed in private companies is being funneled into that cause."

According to Carnrite and his associate, Rhian Davies, who is the company's director of business operations, the mission is to educate and simplify the investing process.

"For us, one of the things we're working on with other organizations is putting together a next-gen investor series, where we are teaching the next generation of investors how to invest and give them a platform to do it," Davies says.

Much like in a normal investment process, the companies provide a pitch deck for potential investors that outlines the business plan and scope of the company. The company simply creates an account and uses the website to develop those materials.

"We standardize that process, so from a user standpoint, everything looks fairly similar on our site and it's a pretty tried and true template," Carnrite says.

While LetsLaunch does its due diligence making sure the business is legitimate and makes sure the pitch deck is sufficient, the investors take it from there.

Since ease of access to funds is the top priority for LetsLaunch, the investment platform has a much lower fee for companies. While some crowdfunding platforms take 10 to 12 percent, LetsLaunch's fee is around 3 percent.

"We really want it to be simple and affordable to businesses and for investors as well," Davies says. "We maintain a much lower fee than other crowdfunding sites."

LetsLaunch will continue to fine tune its existing features on the site, while also adding more tools for businesses, including an iOS mobile app, which Carnirite says will be ready this year. In addition to fundraising tools, Carnrite wants to help their businesses after the campaigns with software that streamlines investor relations and reminds business owners of important deadlines.

"We want to evolve into a website that not only helps you raise capital for a company, but that also helps you run that company after your raise, Carnrite says."

While Houston is home base for the company, the team expects to expand to other markets where fundraising is hard, like Denver, Atlanta, Dallas, and more. Strategic partnerships are another opportunity for LetsLaunch, and the company expects to finalize some of those moving forward.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
