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.

Sensor-enabled rubber ducks that can track weather developments.

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."

Digital duck crossing

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.

Bryan Knouse, co-founder and CEO of Project Owl (organization, whereabouts, and logistics), says the initiative marries:

  • A deployable IoT network of DuckLink devices that can quickly provide a basic WiFi setup where communications infrastructure might be down, like a region where a hurricane just hit. A single device can connect through WiFi to smartphones and laptops.
  • A software data visualization platform that speeds up and simplifies data monitoring on the Clusterduck network.

"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," Knouse 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.

"Once this network of ducks is deployed and then clustered, civilians are able to basically get on the devices through a really intuitive interface and contact first responders with a list of things that are really essential to them," Project Owl team member Magus Pereira explained in an October 2018 blog post.

Project Owl, which won IBM's Call for Code Global Challenge in 2018, is being developed by Code and Response, an IBM program that puts open source technologies in communities that most need them. Knouse and Houston software engineer Charlie Evans lead Project Owl.

In a June 6 blog post, Evans recalled the widespread damage his hometown suffered during Hurricane Harvey and stressed the importance of efforts like Project Owl.

"The sheer magnitude of storms like this," Evans writes of Hurricane Harvey, "and the fact that extreme weather isn't going anywhere anytime soon, really drive home the point that effective communication and logistics are among the highest [priorities] for organizations that are involved with rescuing people and with cleanup."

Katy was the second pilot site for Project Owl. The first large-scale test was done in March in Puerto Rico.

Members of the Project Owl team were pleased with the Katy test. Knouse says the speed of DuckLink deployment improved versus the Puerto Rico test, and the network error transmission rate fell from more than 30 percent to around 10 percent.

"This test is important for anyone who wants to see how we will support communities during natural disasters," Knouse tells InnovationMap. "The growth and improvement [seen in the Katy test] confirms that we can continue to improve the speed, scale, and performance of the network, elevating confidence that if it's deployed during a real disaster, we can support recovery and critical life saving activities."

Following the Puerto Rico and Katy pilots, Project Owl will test the technology again later this year in Puerto Rico, as well as in Alabama, California, and Washington state, according to Knouse.

"It's one thing to build something in a lab and say, 'It works.' It's another to have complete strangers watch the technology deployment and say, 'It works — we need this as soon as possible.' And we are working at maximum capacity to make that happen," Knouse wrote in May.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
