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

Self-deploying flood protection for buildings

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.

Rain rain, go away

Tasha Nielsen was on a trip to Denmark when she came across a Danish company making strides in flood prevention techniques.

"We were visiting family one day when we turn on the news and see FloodFrame's brand launch," Nielsen says. "The inventors live in Denmark, and they've done installations in Denmark, Germany and England, and they've been very successful."

That company partnered with the Danish Technological Institute and the Danish Hydraulic Institute and worked for years perfecting their flood prevention system. After Nielsen asked whether she could contract FloodFrame to install their system at her home back in Houston, she learned the founders weren't interested in coming over themselves to expand their business to the United States.

So, Nielsen took the reins to create the U.S. iteration of FloodFrame. The company provides flood protection to any building, including your home or business. And while it definitely takes inspiration from its European counterpart, Nielsen used her degree in civil engineering from Texas A&M — specifically her speciality in hydraulics, hydrology and storm design — to launch the business in one of the most flood-ravaged cities in the United States: Houston.

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.

FloodFrame adds a level of security during flooding events and can be considered more cost-effective when compared to the high cost of renovating or rebuilding after flooding.

"Right now we are focused on residential but I think there's a huge potential for it to go commercial. A lot of commercial buildings are self insured, and commercial developers, industrial developers, this would be a drop in the bucket for the overall cost of the entire project," Nielsen tells InnovationMap. "For homeowners, it's kind of a bigger expense, but I think there is the potential for homebuilders to include it as an option in the entire package of a new house because when you put it in to a mortgage, it's only another like $0.50 a month."

Nielsen and the company are wrapping up their time in MassChallenge Texas' inaugural Houston cohort, which concludes early September.

Two years after Harvey, Nielsen thinks the city of Houston is doing the right thing by having workshops and meetings in order to work on ways to redesign the city so flooding isn't an issue.

"I do think there needs to be a better plan for what happens next year, instead of trying to prevent what happens in 20 years," she says. "They're already doing that part; they're working on it. I think there just needs to be more of an emphasis on 'what can we actually do to help people right now.'"

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
