A Houston startup is celebrating its nationwide launch of its flagship product that coats roofs to reduce energy waste.

NanoTech's Nano Shield Cool Roof Coat is a unique product that can be added onto roofs to reduce energy waste on buildings. Co-founder and CEO Mike Francis and Chief Commercial Officer Carrie Horazeck joined the Houston Innovators Podcast to share more details about the product.

"It's just a coating that can go on top of existing structure — any type of commercial roof," Horazeck says on the show. "We have a pretty good amount of data from 2022 showcasing that we can reduce HVAC consumption within the building by about 30 to 40 percent.

"Our clients really see a immediate benefit in their energy bill, and, of course, if you reduce the HVAC consumption, that automatically translates to a decrease in your scope one emissions," she continues. Continue reading.


Episode 181 - Gearing up for high-speed global travel - Sassie Duggleby of Venus Aerospace

Sarah "Sassie" Duggleby is on a mission to get people home in time for dinner — whether they are traveling around the world or working for her business. That's why she founded Venus Aerospace, which is developing hypersonic space planes. It's also why she relocated the company from the West Coast to Houston.

"We knew we had to find a location where we could test our engine and still be home for dinner," Duggleby says on this week's episode of the Houston Innovators Podcast. "Our company vision is 'home for dinner.' We want to fly you across the globe and have you home for dinner. And, if you work for us, we want you home for dinner."

Venus's technology enables this revolutionary travel through its supersonic combustion engine — more akin to a rocket's engine than an airplane's — that allows for travel at a higher elevation, she explains on the show. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally. And, as Duggleby explains, the engine can go further with the same amount of fuel, so it's a more sustainable way of traveling too. Continue reading.

When Howard Berman sought out renowned Houston Methodist researcher and neurologist Dr. Stanley Appel, he was looking for treatment for his father, who was suffering from dementia. He wasn't looking for a job, but Dr. Appel had other ideas and asked Berman to meet with him.

"I was interested in what I could do for my dad," Berman says on the Houston Innovators Podcast, explaining how he took the meeting with Dr. Appel, who then presented him with some of his research. "By slide five my jaw had hit the ground.

"He had shown that he could stop the progression in one of his early trials of ALS," Berman says.

Not too long after that meeting, Berman, who founded digital health platform imaware, joined Dr. Appel to lead commercialization of Coya Therapeutics, a biotech startup that raised over $20 million in venture funding before going public a few months ago. Continue reading.

Ramanan Krishnamoorti has had a varied career in academia, from an engineering professor to nanotech research. While he never made the transition from researcher to entrepreneur, he managed to snag a CEO title at the university about a decade ago: Chief energy officer.

Since then his role has expanded to include advancing UH's innovation of all kinds — from health tech to the arts — as vice president of energy and innovation at UH. In his role, he oversees the UH Technology Bridge, a lab and coworking space for tenants just a short drive away from UH's main campus, as well as future plans, like a new central campus hub for innovation that's in its early stages of development.

"What we really need at the university today is to bring innovation — which tech transfer is a piece of — and connect that to real-world challenges to deliver what the world needs, which is talented folks delivering new innovative, entrepreneurial, or intrapreneurial programs," Krishnamoorti says on this week's episode of the Houston Innovators Podcast.

Innovation isn't always tinkering with tech or programming software, although serial entrepreneur Erik Ibarra knows that world well. Sometimes it's about rethinking how a community improves and develops without doing the residents a disservice.

That's why Ibarra started Magnolia Fund, a mission-driven investment fund dedicated to enriching the East End community and preserving the neighborhood's culture and history. Ibarra, who has lived in the area the majority of his life, says on the Houston Innovators Podcast, that he's looking to turn residents into investors.

"Our investors from the neighborhood, today they walk around and look at their house and say, 'I own that,' and that's great," Ibarra says. "In the future, our investors should be able to say that, and then point to a building and say, 'I own a portion of that building too. And I helped that small business over there.'"

Anshumali Shrivastava's career has evolved alongside the rise of artificial intelligence. Now, he believes his company represents the future of the industry's widespread implementation.

Shrivastava, who's also a professor at Rice University, founded ThirdAI, pronounced "third eye," in 2021 to democratize artificial intelligence through software innovations. As Shrivastava explains on the Houston Innovators Podcast, AI processes have historically been run on larger, less accessible computing hardware. ThirdAI's tools are able to run on a regular central processing unit, or CPU, rather than the more powerful graphics processing unit, or GPU.

"We focus on the problems that people are facing in the current AI ecosystem," Shrivastava says on the podcast. "Right now, if you are to build some of the large-language models and (linear programming) models, you need a lot of computing power, dedicated engineers to move it, and, even if you are using fully managed services, it's costly and there are a lot of privacy implications because you have to move data around."

For years, Hello Alice has been helping small businesses across the country get equitable access to funding and support. Now, the Houston tech company is facing its own obstacle: An affirmative action lawsuit.

"I don't think in a million years that we ever expected anything like this," Elizabeth Gore, co-founder and president of Hello Alice, says on the Houston Innovators Podcast. "There's surprise, then there's fear, and then there's anger. But now on the other side of it, we're emboldened, confident, and more passionate than ever."

America First Legal's lawsuit against Hello Alice and its partner, Progressive Insurance, alleges that their program to award10 $25,000 grants to Black-owned small businesses constitutes racial discrimination. AFL was founded by former Trump Administration adviser Stephen Miller and features a handful of other former White House officials on its board. Continue reading.

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.

It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

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.
