In light of Houston's frequent floods, a local organization has formed to encourage innovation in resiliency — especially as the city moves throughout the 2020 hurricane season.

The Gulf Coast & Southwest Resilience Innovation Hub was founded last month by the Insurance Information Institute and ResilientH20 Partners in The Cannon's downtown location. The organization is looking into the best innovations within resiliency — especially as it pertains to Houston, where nine of the 10 most expensive hurricanes in the United States have occurred in the past 16 years.

"There has been a widespread interest in, and demand for, best-in-class actionable, alternative disaster mitigation solutions since 2017's Hurricane Harvey and subsequent storms caused extensive insured losses to autos, homes, businesses, and governmental properties," says Richard Seline, managing partner of ResilientH2O Partners, in a news release.

The organization held a virtual panel and pitch session that featured three flood-focused startups. Here are the three companies and their innovative solutions to flood mitigation.

True Flood Risk

Shelly Klose founded her company, True Flood Risk, after she observed Hurricane Sandy devastating New Jersey. But, she wondered, why some homes were hit harder than others. So, she created an artificial intelligence-driven property risk management platform that would easily indicate how susceptible to flood damage each home is. The company even has a way to measure the property's first-floor height based street view images.

"With this key data point for structural height coupled with ground elevation and flood zone data, you have a good indication if that property is at risk," Klose says.

The New York-based company allows users to run their address and learn about their flood damage risk for free — and that's something Klose says thats a tool she's seen used more frequently amid the pandemic.

"What we're finding is people have been so emotionally and financially hit so hard during this pandemic," Klose says. "The last thing you want to do is lose your house."

FloodFrame

Part of the challenge of mitigating flood damage is that it can happen in an instant with little to no warning. FloodFrame provides a solution to that in its self-inflating technology that can detect and prevent flood damage.

FloodFrame works by using buoyancy. A lightweight cloth is wrapped around a tube is installed underground outside the perimeter of your home or business. One end of that cloth is attached to a box that is also installed underground. As flooding begins, an automatic system will release the lids to deploy the inflation of the tube that will protect the structure. When the flood comes in, the system will float on top of the flood — kind of like a pool noodle — and protect the structure from the water. It's easier to install than raising a house, for instance, and can be reused as a long-term solution.

Tasha Nielsen launched the U.S. iteration of FloodFrame — which originated in Denmark — by becoming the company's first franchisee. Now, that process how the company plans to grow and expand and Nielsen is working with home builders and contractors to provide the invention in new homes and buildings. Nielsen also hopes to work with insurance companies, since the device helps prevent costly payouts.

Hundreds of thousands of cars were damaged during Hurricane Harvey, and those car owners faced financial burdens from having to find temporary transportation to repairing or even buying a new vehicle. Rahel Abraham, who lost her car during the storm, founded Houston-based ClimaGuard to help enable people to help protect their cars or possessions from the elements.

"We're providing a resilient, practical, and real-time solution," says Abraham.

The tool is easy to use and affordable, considering the costs of potential damages, with a starting price of $399. The average insurance payout for vehicles was $12,000, Abraham says, so it's actually a great risk mitigation tool for auto insurers.

3 Houston innovators to know this week

Who's who

This week's Houston innovators to keep an eye on are working on technologies that are true testaments to the day and age we live in. From commercial space travel to a product that protects vehicles from floodwaters that are more and more frequent, these entrepreneurs are providing solutions to problems no one even dreamed of having a few decades ago.

Mark Bergsrud, co-founder and CEO of Grab

For over 20 years, Mark Bergsrud worked at the intersection of travel and technology — first at Continental Airlines, then at United Airlines following the merger, and now for himself as the co-founder of Grab, a Houston startup that's making grabbing a bite at the airport way easier.

Grab's technology digitizes and optimizes the airport dining experience — from ordering pickup remotely ahead of time to kiosks or table tablet ordering. The company, which has operations in 37 airports, just closed a multimillion-dollar Series A fundraising round to help continue its growth.

"We've called ourselves a startup for a long time, and now we think of ourselves as more of a scale-up company," Bergsrud says. "Now it's about having the money to scale faster."

For inventors, you can usually pinpoint a particular "eureka" moment. For Rahel Abraham, it was seeing her 2008 Infiniti G35 completely totaled by the rain waters of Hurricane Harvey. She knew there had to be some way to protect cars and valuables from flooding, so she invented ClimaGuard's Temporary Protective Enclosure.

Abraham, who was selected for the 12-week DivInc accelerator program in Austin for her company, wants to make the product available to everyone.

"My goal is not to make it to where it's an exclusive product — available only to those who can afford it — but I want to be able to help those who it would make even more of an economic impact for," Abraham says.

Arturo Machuca is playing a waiting game. Various companies are developing commercial spaceflight and — whether that technology delivers in two years or 10 years, Machuca wants Houston to be ready. Ellington Airport and the Houston Spaceport are being developed throughout a multiphase, multimillion-dollar process, while also serving as an active airport.

"We use what we already have at Ellington Airport," Machuca tells InnovationMap. "We're serving aviation today until commercial spaceflight gets here."

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.
