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.

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.'"

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.
