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.

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.

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.

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 brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.
