Tilman Fertitta, Elon Musk, Alice Walton, and Jerry Jones are members of the billionaires club in Texas. But just how many millionaires does the Lone Star State boast?

Altogether, 73,930 Texans were classified as millionaire tax filers in 2022, according to an analysis of IRS data by digital marketing firm Hennessey Digital. (For context, that millionaire count is just a few thousand shy of the entire population of Missouri City.) This figure puts Texas in the No. 2 spot for the country’s biggest population of millionaire taxpayers, behind first-place California.

However, if you crunch the figures a different way, Texas’ millionaire status isn’t quite as impressive, demonstrating that not everything is bigger in Texas. Texas ranks 10th among the states with the highest proportions of millionaire taxpayers, the study indicates. According to Hennessey Digital’s calculations, 27.1 of every 10,000 Texas tax filers reported adjusted gross income of at least $1 million for the 2022 tax year.

“The state’s booming economy, driven by energy, technology, and business-friendly policies, contributes to its wealthy population,” says Hennessey Digital.

Forbes ranked 43 Texans among the 400 wealthiest Americans last year, with Elon Musk topping the list. Houston hospitality king, Rockets owner, and newly appointed ambassador to Italy Tilman Fertitta was the 12th richest Texan and the 99th richest person in the United States, according to Forbes.

Which state comes out on top for the largest share of millionaire taxpayers? Connecticut, with 44.76 millionaire tax filers for every 10,000 filers, the Hennessey study shows. A number of well-to-do Connecticut suburbs are situated just a commuter train ride away from New York City, where bankers, brokers, and others pull in the big bucks. (Connecticut sits two spots above New York state in the millionaire ranking.)

The numbers in the study “highlight the diverse economic landscapes across our nation. States with favorable tax policies and thriving industries tend to attract more high-income earners,” says Jason Hennessey, CEO of Hennessey Digital. “Understanding these patterns can provide valuable insights for businesses and individuals making decisions about where to live, work, or invest.”

Texas ranks No. 5 worst state for package delays in U.S., report says

out for delivery

One of the biggest headaches of online shopping and package shipping is the potential for delivery issues, and Texas is among the worst places for them, according to a new study.

Online retailer Overnight Glasses determined that Texas is the No. 5 worst state for package delays, based on a nationwide analysis of internet searches regarding delayed or lost packages, statewide United States Postal Service (USPS) performances, and freight flows per capita.

The data showed Texas had the highest freight flow compared to the rest of the U.S., raking in $3.64 billion. But the state’s massive population is a major factor contributing to “logistical challenges,” as shown in Texas’ local USPS performance rates.

“The USPS performance rate in Texas at an average 65 percent, and issues with timely deliveries, as reflected in the search value of 85.0 gives the state a high position in the ranking,” the report said.

Given the vast number of packages being sent through Texas’ delivery infrastructure, it’s safe to say Santa's going to be working overtime to fulfill the online orders for Houston's biggest spenders over the holidays.

The absolute worst place in the U.S. for package delays was North Dakota, which ranked as the No. 1 worst state for package delays.

The study found residents frequently search delivery issue terms such as “package delayed” or “order not delivered,” which doesn’t bode well for a state with a population of just 783,000.

“In today’s world, where everyone expects quick deliveries, even small hiccups can lead to a lot of frustration,” an Overnight Glasses spokesperson said. “I think this study highlights a real need for companies to invest in better, more flexible logistics networks, especially in states where freight flow is high.”

The best state for getting your packages delivered in a timely manner was Hawaii, followed by Oklahoma, West Virginia, Maryland, and Mississippi.

The top 10 worst U.S. states for package delivery issues are:

  • No. 1 – North Dakota
  • No. 2 – Georgia
  • No. 3 – Illinois
  • No. 4 – New York
  • No. 5 – Texas
  • No. 6 – Wyoming
  • No. 7 – Washington
  • No. 8 – Virginia
  • No. 9 – Massachusetts
  • No. 10 – South Carolina

Here's how Texas towns stacked up on a new population report. Photo via Getty Images

Booming Houston suburb, other Texas towns among the fastest-growing U.S. cities in 2023

by the numbers

One Houston suburb experienced one of the most rapid growth spurts in the country last year: Fulshear, whose population grew by 25.6 percent, more than 51 times that of the nation’s growth rate of 0.5 percent. The city's population was 42,616 as of July 1, 2023.

According to U.S. Census Bureau's Vintage 2023 Population Estimates, released Thursday, May 16, Fulshear — which lies west of Katy in northwest Fort Bend County - ranked No. 2 on the list of fastest-growing cities with a population of 20,000 or more. It's no wonder iconic Houston restaurants like Molina's Cantina see opportunities there.

The South still dominates the nation's growth, even as America’s Northeast and Midwest cities are rebounding slightly from years of population drops. The census estimates showed 13 of the 15 fastest-growing cities in the U.S. were in the South — eight in Texas alone.

The Texas cities joining Fulshear on the fastest-growing-cities list are:

  • Celina (No. 1) with 26.6 percent growth (42,616 total population)
  • Princeton (No. 3) with 22.3 percent growth (28,027 total population)
  • Anna (No. 4) with 16.9 percent growth (27,501 total population)
  • Georgetown (No. 8) with 10.6 percent growth (96,312 total population)
  • Prosper (No. 9) with 10.5 percent growth (41,660 total population)
  • Forney (No. 10) with 10.4 percent growth (35,470 total population)
  • Kyle (No. 11) with 9 percent growth (62,548 total population)

Texas trends
San Antonio saw the biggest growth spurt in the United States last year, numbers-wise. The Alamo City added about 22,000 residents. San Antonio now has nearly 1.5 million people, making it the the seventh largest city in the U.S. and second largest in Texas.

Its population boom was followed by those of other Southern cities, including Fort Worth; Charlotte, North Carolina; Jacksonville, Florida; and Port St. Lucie, Florida.

Fast-growing Fort Worth (978,000) surpassed San Jose, California (970,000) to become the 12th most populous city in the country.

Meanwhile, population slowed in the Austin area. Jacksonville, Florida (986,000), outpaced Austin (980,000), pushing the Texas capital to 11th largest city in the U.S. (barely ahead of Fort Worth).

Population growth in Georgetown, outside Austin, slowed by more than one-fourth its population growth in 2022, the report says, from 14.4 percent to 10.6 percent. It's the same story in the Central Texas city of Kyle, whose population growth decreased by nearly 2 percent to 9 percent in 2023.

Most populated cities
New York City with nearly 8.3 million people remained the nation's largest city in population as of July 1, 2023. Los Angeles was second at close to 4 million residents, while Chicago was third at 2.7 million and Houston was fourth at 2.3 million residents.

The 15 populous U.S. cities in 2023 were:

  1. New York, New York (8.3 million)
  2. Los Angeles, California (4 million)
  3. Chicago, Illinois (2.7 million)
  4. Houston, Texas (2.3 million)
  5. Phoenix, Arizona (1.7 million)
  6. Philadelphia, Pennsylvania (1.6 million)
  7. San Antonio (1.5 million)
  8. San Diego, California (1.4 million)
  9. Dallas (1.3 million)
  10. Jacksonville, Florida (986,000)
  11. Austin (980,000)
  12. Fort Worth (978,000)
  13. San Jose (970,000)
  14. Columbus, Ohio (913,000)
  15. Charlotte, North Carolina (911,000)

Modest reversals of population declines were seen last year in large cities in the nation's Northeast and Midwest. Detroit, for example, which grew for the first time in decades, had seen an exodus of people since the 1950s. Yet the estimates released Thursday show the population of Michigan’s largest city rose by just 1,852 people from 631,366 in 2022 to 633,218 last year.

It's a milestone for Detroit, which had 1.8 million residents in the 1950s only to see its population dwindle and then plummet through suburban white flight, a 1967 race riot, the migration to the suburbs by many of the Black middle class and the national economic downturn that foreshadowed the city's 2013 bankruptcy filing.

Three of the largest cities in the U.S. that had been bleeding residents this decade staunched those departures somewhat. New York City, which has lost almost 550,000 residents this decade so far, saw a drop of only 77,000 residents last year, about three-fifths the numbers from the previous year.

Los Angeles lost only 1,800 people last year, following a decline in the 2020s of almost 78,000 residents. Chicago, which has lost almost 82,000 people this decade, only had a population drop of 8,200 residents last year.

And San Francisco, which has lost a greater share of residents this decade than any other big city — almost 7.5 percent — actually grew by more than 1,200 residents last year.

Houston scores respectable rank in new report of best U.S. cities for working-class families

is the living easy?

A new economic analysis by the Ludwig Institute for Shared Economic Prosperity (LISEP) has revealed that Houston-The-Woodlands-Sugar Land has the 30th most prosperous local economy in the nation. The analysis ranked the 50 largest Metropolitan Statistical Areas (MSAs) in the U.S. based on several localized economic factors.

According to Houston's data, the region's population has skyrocketed 18.7 percent within the last decade, now reaching over 7.34 million people. The median age of an Houston-area resident is 35.1-years-old.

The three main criteria that determined Houston's prospering rank include a "True Living Cost" metric that tracks price changes for essential household necessities; a "True Weekly Earnings" calculation that determines the median weekly earnings of all workers (including part-timers and those who are unemployed); and a "True Rate of Unemployment Out of the Population" metric that measures the percentage of people unable to find full-time employment with a living wage.

The findings show that a little more than half of all Houston-area households are earning enough income to afford their basic needs. The remaining 46.4 percent are struggling due to a high cost of living, the report said.

"The total costs of necessities for a 4-person family [in Houston-The Woodlands-Sugar Land] increased 58.2 percent since 2005 from $54,052 to $85,492," the report said.

Furthermore, Houstonians are bringing home higher weekly earnings than they were in 2020. Houston workers are earning a median $894.89 per week, or about $47,429.17 a year. The report states the average employee has gained 8.2 percent more purchasing power since 2005, and the average Houston household has 8.1 percent of their income leftover after their necessities.

Houston's "True Rate of Unemployment Out of the Population" is 63 percent, according to the analysis.

The objective behind LISEP's report is to help policymakers assess their local economies' dynamics and to assess how much low-income and working-class families are affected, according to LISEP Chairman Gene Ludwig in the release.

"Across the nation we are seeing both ends of the spectrum — communities where middle- and working-class families are faring well and others where financial survival remains a struggle," Ludwig said. "Our challenge here is in identifying what's working well and replicating it; what's not, and scrapping it. This is where real-world data can be invaluable to policymakers."

Houston-The Woodlands-Sugar Land wasn't the only Texas metro area to earn a spot in the analysis. Austin-Round Rock worked its way up into No. 2 nationally, while San Antonio-New Braunfels ranked just outside the top 10 at No. 13. Dallas-Fort Worth-Arlington ranked four spots higher than Houston at No. 26.

The top 10 highest-performing economies in the U.S. are:

  • No. 1 – San Jose-Sunnyvale, Santa Clara, California
  • No. 2 – Austin-Round Rock, Texas
  • No. 3 – San Francisco-Oakland-Hayward, California
  • No. 4 – Baltimroe-Columbia-Towson, Maryland
  • No. 5 – Washington-Arlington-Alexandria, District of Columbia-Virginia-Maryland
  • No. 6 – Minneapolis-St. Paul-Blookington, Minnesota-Wisconsin
  • No. 7 – Portland-Vancouver-Hillsboro, Oregon-Washington
  • No. 8 – Milwaukee-Waukesha-West Allis, Wisconsin
  • No. 9 – Denver-Aurora-Lakewood, Colorado
  • No. 10 – Salt Lake City, Utah
The full report and its methodology can be found on lisep.org.

Texas and California battle it out for most relocating residents, Census report says

by the numbers

Texans love to joke about how many Californians are moving here, but a rising trend in Texas residents' relocation habits may have Californians saying the same thing about Texans soon.

A new U.S. Census report analyzing state-to-state migration has revealed new estimates regarding Texas' growing population in 2022. According to the report, more than 668,000 new residents relocated to Texas from out-of-state last year.

Not surprisingly, the highest number of new Texans hailed from California. More than 102,000 Californians made the move to the Lone Star State in 2022.

But in a fun population twist, California also received the most Texpats in 2022, the report showed, followed closely behind by Florida, then Oklahoma. Of the 494,077 people who left Texas last year, 42,279 went to California.

Why Californians move to Texas
Californians often seek out a lower cost of living by moving to the most "affordable" cities in the state. Houston has shown to be at the top of the priority destination list; Dallas usurped Austin as the No. 1 city for California movers earlier this year. And when a California transplant can save more than $646,000 by moving to Texas and buying a home in Houston, it's not hard to see the appeal

Other reasons for the California-to-Texas exodus include the lack of income tax and the flexibility of remote work opportunities, they say.

While California took the lead with the most new movers flocking to Texas, Floridians are also choosing to pack up and leave their Sunshine State for the Lone Star State, the report says.

The top 5 states with the most residents moving to Texas in 2022 were:

  • California – 102,442 new residents
  • Florida – 41,747 new residents
  • New York – 30,890 new residents
  • Illinois – 25,272 new residents
  • Louisiana – 25,192 new residents

Where Texans are moving
The Census report showed that less than half a million Texas residents relocated out-of-state last year, totaling 494,077 people.

"Texas had the country's lowest (11.7 percent) outmigration rate, with most of those who did move relocating to California (42,479) or Florida (38,207)," the report said.

The top five states where Texans moved in 2022 were:

  • California – 42,279 Texans
  • Florida – 38,207 Texans
  • Oklahoma – 26,440 Texans
  • Colorado – 25,466 Texans
  • Georgia – 23,754 Texans

New Texans from abroad
In addition to state-by-state migration data, the report also provided estimates for how many new Texans came from abroad. Out of 237,051 new residents, the majority – 233,751 people – relocated from outside the mainland last year.

About 2,441 people moved from Puerto Rico, and 859 arrived from unspecified U.S. island areas.

Texas has been a magnet for international homebuyers for several years. The state has held its position as the third hottest U.S. housing market for international homebuyers for the fourth consecutive year in 2023. A total of 9,900 Texas homes were purchased by buyers from outside the U.S last year, spending a gigantic sum of $4.3 billion.

Chicago and New York residents are eyeing Houston. Getty Images

Report finds two major metros are the biggest sources of new Houstonians

new to hou

Despite the current state of things — a pandemic, historic unemployment numbers, and an unstable economy — people are still thinking of moving. And, according to Apartment List, they have eyes on Texas.

The website's quarterly Renter Migration Report is out, using searches made on its platform between January 1 and April 15, 2020, to map where renters are looking to make their next move.

Chicago (3.3 percent), New York (3.4 percent), and San Antonio (22.8 percent) are also eyeing Houston, while H-Town residents are looking to keep it close in Dallas (8.9 percent), San Antonio (6.8 percent), and Austin (6.6 percent).

Austin is the most popular Texas city in the report, with the region increasingly being seen as an alternative to the expensive coastal metros where tech jobs have historically clustered. A staggering 70.9 percent of searches for apartments in Austin come from outside the metro, Apartment List reports, the highest share among the nation's 50 largest metros.

Aside from the 25 percent searching from San Antonio, the 4.6 percent from Dallas, and the 4.5 percent from Houston, 4.2 percent of renters searching for apartments in Austin currently live in the New York City metro. Furthermore, 2.5 percent of inbound searches to Austin are coming from Los Angeles and an additional 2.5 percent are coming from the San Francisco Bay Area.

For as many people who want to enter Austin from San Antonio, there's nearly the same amount that would be doing the opposite. Austin renters searched for San Antonio (16.8 percent), Dallas (7.9 percent), and College Station (6.4 percent).

While current Chicago residents and New Yorkers are typing "Dallas" into their search bars, accounting for 3.6 percent and 3 percent of data exploring Big D, respectively, it's San Antonians who are truly interested. A whopping 23.1 percent of current Alamo City residents made exploratory apartment searches in Dallas this past quarter. Overall, 32.8 percent of those looking for a place to live in Dallas are searching from outside the metro.

Meanwhile, 8.7 percent of apartment hunters currently living in Dallas are looking to move elsewhere. They searched for Houston (4.9 percent), San Antonio (4.8 percent), and Los Angeles (4.5 percent).

And though we've heard about it several times, where does San Antonio fall in all this? Turns out renters who currently live there are thinking about moving to Dallas (17.7 percent), followed by Houston (12.4 percent) and Austin (8.4 percent). Residents of McAllen (5 percent), Dallas (3.9 percent), and Houston (3.5 percent) are considering making San Antonio home.

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.
