These Houston entrepreneurs and startups are searching for flooding solutions

Flood tech

The feeling is all too familiar for Houstonians. Tropical Storm Imelda hit Houston with devastating flood waters just two years after Hurricane Harvey did its damage.

With any obstacle or challenge, there is room for innovation. Over the past year, InnovationMap has covered various flood tech startups in Houston. Here are six innovations that can make a difference the next time a storm decides to take its toll on Houston.

Self-deploying flood protection for buildings

A self-deploying flood damage prevention device caught Tasha Nielsen's eye on a trip to Denmark, and then launched the U.S. iteration of FloodFrame to bring the technology here.

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.

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."

Floodwaters from Hurricane Harvey seriously damaged about 600,000 vehicles in the Houston area, which included Rahel Abraham's 2008 Infiniti G35. Now, Abraham's brainchild forms the backbone of her Houston-based startup, ClimaGuard LLC. The company's waterproof, temperature-resistant, portable Temporary Protective Enclosure (TPE) can entirely cover a compact car, sedan, or midsize SUV. It comes in three sizes; the cost ranges from $349 to $499.

To protect a vehicle, someone sets a TPE on the ground, a driveway, or another flat surface, then drives the vehicle onto the bottom part of the product, and connects the bottom and top parts with the zipper. Abraham likens it to a clamshell preserving a pearl.

"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 tells InnovationMap.

A network to find shelter.

It only took a natural disaster for Reda Hicks to make her startup idea into a reality.

"I had been thinking on what it would be like to help people find space to do business in and how businesses find a way to stay in business a long time," Hicks tells InnovationMap. "But, I was afraid of the tech."

Hicks, who has practiced law for almost 15 years, wanted to create a website that allows for people with commercial space — a commercial kitchen, conference room, spare desks, etc. — to list it. Then, space seekers — entrepreneurs, nonprofits, freelancers, etc. — can rent it. When Hurricane Harvey hit, Hicks was kicking herself for not acting on her idea sooner.

"It was really Harvey and having so many people desperate to find space for emergency purposes that made me realize there are so many contexts in which people need space right away for something specific," she says. "Certainly the primary user is the entrepreneur trying to grow their business, but there are so many other reasons why a community would need better access to the space it already has."

Now Hicks is growing GotSpot in hopes that short-term rental space and emergency housing can be smooth sailing no matter the circumstances. Recently, the company was named a finalist for MassChallenge Texas in Austin.

In the wake of Hurricane Harvey, many Houstonians began to think of solutions for the next time Mother Nature struck with her full-force of flooding. Gensler designers Chelsea Bryant, Jordan Gomez, Luisa Melendez, Barbara Novoa, Benjamin Nanson, Maria Qi, and Melinda Ubera created a solution as a part of Gensler's By Design program called Fil Trat. The tower can absorb, filter, and store flood waters until the bayou is ready for the water to be released — cleaner than it was before.

During Harvey, thousands of people were displaced, but Fil Trat has a solution for that too. The tower's floors would alternate between filtration floors and shelters, which could house up to 24 families per floor.

While the suggested Houston locale would be by Buffalo Bayou, the group suggests putting the tower in other coastal cities at risk of devastating flooding.

Nearly two years after Hurricane Harvey battered the Houston area, a flock of electronic "rubber ducks" flew above homes in Katy in a broader endeavor to keep first responders and victims connected during natural disasters.

Developers and backers of Project Owl, an Internet of Things (IoT) hardware and software combination, conducted a pilot test of this innovation June 1 — the first day of this year's hurricane season. In the Katy test, 36 "ducks" took flight.

"So, our technology can be deployed to help communities that have been destroyed after natural disasters by providing quickly accessible communications network to coordinate and organize a response," Bryan Knouse, co-founder and CEO of Project Owl, tells InnovationMap.

The DuckLink network comprises hubs resembling rubber ducks, which can float in flooded areas if needed. It takes only five of these hubs to cover one square mile. This network sends speech-based communications using conversational systems (like Alexa and Facebook Messenger) to a central application. The app, the Owl software incident management system, relies on predictive analytics and various data sources to build a dashboard for first responders.

Before it was the fourth largest city in America, Houston was a prairie. That type of ecosystem — thick with prairie grass — is very absorbing when it comes to rain water. Cassidy Brown Johnson, a Rice University lecturer and president of the Coastal Prairie Partnership, has been taking every opportunity to raise awareness on the importance of prairie restoration.

"It's really surprising to people that the trees and all this lushness is actually all artificial," Johnson says. "We know that this ecosystem evolved with the cyclical flooding events that happened here."

This movement to bring back Houston's ancient ecosystem is a new focus on a few prairie conservationist groups — and even the Harris County Flood Control. This has been going on for a while, but recent flooding events have opened the eyes of people now looking for reliable solutions to flooding problems.

"After Hurricane Harvey, people started realizing that this might be one of the solutions we could actually investigate and see if it can help us," Johnson says. "A green space is going to absorb way more water than a parking lot."

Memorial Park Conservancy's master plan redevelopment project, which is being supported by the Kinder Foundation, includes a lot of prairie restoration plans is expected to deliver by 2028.

The project is a collaborative effort between MPC, Uptown Houston TIRZ, and Houston Parks, Kinder Foundation, and Recreation Department to redevelop the 1,500-acre park. An ongoing part of the transformation will be stormwater management upgrades. MPC has budgeted $3 million to this asset of the renovation. While a part of the plan is tributaries for run-off water, bringing back prairie and wetlands will do a great deal to help abate stormwater.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," MPC president and CEO Shellye Arnold tells InnovationMap. "This serves important stormwater purposes."

Texas university's innovative 'WaterHub' will dramatically reduce usage by 40%

Sustainable Move

A major advancement in sustainability is coming to one Texas university. A new UT WaterHub at the University of Texas at Austin will be the largest facility of its kind in the U.S. and will transform how the university manages its water resources.

It's designed to work with natural processes instead of against them for water savings of an estimated 40 percent. It's slated for completion in late 2027.

The university has had an active water recovery program since the 1980s. Still, water is becoming an increasing concern in Austin. According to Texas Living Waters, a coalition of conservation groups, Texas loses enough water annually to fill Lady Bird Lake roughly 89 times over.

As Austin continues to expand and face water shortages, the region's water supply faces increased pressure. The UT WaterHub plans to address this challenge by recycling water for campus energy operations, helping preserve water resources for both the university and local communities.

The 9,600-square-foot water treatment facility will use an innovative filtration approach. To reduce reliance on expensive machinery and chemicals, the system uses plants to naturally filter water and gravity to pull it in the direction it needs to go. Used water will be gathered from a new collection point near the Darrell K Royal Texas Memorial Stadium and transported to the WaterHub, located in the heart of the engineering district. The facility's design includes a greenhouse viewable to the public, serving as an interactive learning space.

Beyond water conservation, the facility is designed to protect the university against extreme weather events like winter storms. This new initiative will create a reliable backup water supply while decreasing university water usage, and will even reduce wastewater sent to the city by up to 70 percent.

H2O Innovation, UT’s collaborator in this project, specializes in water solutions, helping organizations manage their water efficiently.

"By combining cutting-edge technology with our innovative financing approach, we’re making it easier for organizations to adopt sustainable water practices that benefit both their bottom line and the environment, paving a step forward in water positivity,” said H2O Innovation president and CEO Frédéric Dugré in a press release.

The university expects significant cost savings with this project, since it won't have to spend as much on buying water from the city or paying fees to dispose of used water. Over the next several years, this could add up to millions of dollars.

Texas female-founded companies raised more than $1 billion in 2024, VC data shows

by the numbers

Female-founded companies in Dallas-Fort Worth may rack up more funding deals and more money than those in Houston. However, Bayou City beats DFW in one key category — but just barely.

Data from PitchBook shows that in the past 16 years, female-founded companies in DFW collected $2.7 billion across 488 deals. By comparison, female-founded companies in the Houston area picked up $1.9 billion in VC through 343 deals.

Yet if you do a little math, you find that Houston ekes out an edge over DFW in per-deal values. During the period covered by the PitchBook data, the value of each of the DFW deals averaged $5.53 million. But at $5,54 million, Houston was just $6,572 ahead of DFW for average deal value.

Not surprisingly, the Austin area clobbered Houston and DFW.

During the period covered by the PitchBook data, female-founded companies in the Austin area hauled in $7.5 billion across 1,114 deals. The average value of an Austin deal: more than $6.7 million.

Historically, funding for female-established companies has lagged behind funding for male-established companies. In 2024, female-founded companies accounted for about one-fourth of all VC deals in the U.S., according to PitchBook.

PitchBook noted that in 2024, female-founded companies raised $38.8 billion, up 27 percent from the previous year, but deal count dropped 13.1 percent, meaning more VC for fewer startups. In Texas, female-founded companies brought in $1.3 billion last year via 151 deals. The total raised is the same as 2023, when Texas female founders got $1.3 billion in capital across 190 deals.

“The VC industry is still trying to find solid footing after its peak in 2021. While some progress was made for female founders in 2024, particularly in exit activity, female founders and investors still face an uphill climb,” says Annemarie Donegan, senior research analyst at PitchBook.
