Richard Seline says on this week's episode of the Houston Innovators Podcast, that people are exhausted and these feelings are festering into frustration and anger — and calling for change. The things that need to change, Seline says, includes growing investment and innovation in resilience solutions.

"As a fourth generation Houstonian, it's just so hard to see my hometown get hit persistently with a lot of these weather and other type of disasters," Seline says.

These unprecedented disasters — which are of course occurring beyond Houston and Texas — have also sparked a growing interest in change for insurance companies that have lost a trillion dollars on the United States Gulf Coast over the past seven years, Seline says. Something has got to change regarding preparation and damage mitigation. Read more and stream the podcast.

Deanna Zhang specializes in energy tech, and what she witnessed from February's winter weather was basically an epic fail caused by a myriad of issues.

"But it's oversimplifying to say that the only solution to preventing another situation like this is continued or increased reliance on the oil and gas industry," she writes in a guest article for InnovationMap. "What last week ultimately demonstrated was the multitude of technology solutions that needs to scale up to provide us with the best energy reliability and availability." Read more.

A Houston company has created a technology that uses sound to make changes in human skin tissue. Soliton, led by Brad Hauser, is using audio pulses to make waves in the med-aesthetic industry. The company, which is licensed from the University of Texas on behalf of MD Anderson, announced that it had received FDA approval earlier this month for its novel and proprietary technology that can reduce the appearance of cellulite.

"The original indication was tattoo removal," Hauser says. "The sound wave can increase in speed whenever it hits a stiffer or denser material. And tattoo ink is denser, stiffer than the surrounding dermis. That allows a shearing effect of the sound wave to disrupt that tattoo ink and help clear tattoos."

According to Hauser, the team then turned to a second application for the technology in the short-term improvement in the appearance of cellulite. With the use of the technology, patients can undergo a relatively pain-free, 40- to 60-minute non-invasive session with no recovery time. Read more.

Houston expert: Winter storm Uri's devastation should be a reminder to prioritize innovative energy solutions

guest column

Texas has landed itself in the middle of a fierce debate following what's been considered one of the worst winter storm in recent history for the state.

Uri wreaked havoc as it rolled through regions that were wholly unprepared for the sudden temperature drops, single digit wind chills, and unusual precipitation (e.g. thundersnow in Galveston). Rolling power outages and water shortages affected more than 4.5 million Texans. Businesses like grocery stores and restaurants — unable to wash food or sanitize equipment or even turn on the lights, —closed throughout the ordeal, leaving many families without food, water, or power.

For most, this was an unprecedented experience. The majority of catastrophes in Texas are in the form of warm weather events like floods, hurricanes, or tornadoes, which means that even if power is lost, freezing is rarely an issue. Uri turned this upside down. ERCOT's failure to provide reliable energy for days on end led to families sleeping in devastatingly cold temperatures, further water shortage due to municipal water facilities failing, carbon monoxide deaths, disruption in vaccine rollouts, hospitals overrun with people needing to charge essential medical equipment, and much more. Uri highlighted in harrowing detail the domino effect that energy (and lack thereof) has on everything around it.

A single source of ERCOT's failure is hard to pinpoint. The cold led to production shut-ins, exacerbating the existing natural gas supply shortage and resulted in the RRC prioritizing "direct-to-consumer" natural gas delivery (i.e. to residences, hospitals, schools, etc.) over natural gas for the grid. Iced-over gas lines disrupted this flow even further. Freezing temperatures shut off some wind turbines and solar panels (if they were not already covered in snow). Coal and nuclear plants in Texas also shut down due to frozen instruments and equipment.

Thrown into sharp relief was the importance of consumer access to natural gas and other fossil fuels like propane. Most homes that had completely electrified (including my own) were ill-prepared to heat their homes without access to the grid or backup generators. Residential and community solar did little to alleviate this problem in many cases as lower technology configurations either froze, were not able to capture enough energy from a low-light environment, or were covered in snow. Having access to gas for heating or a propane stove was a lifeline for most folks.

But it's oversimplifying to say that the only solution to preventing another situation like this is continued or increased reliance on the oil and gas industry.

What last week ultimately demonstrated was the multitude of technology solutions that needs to scale up to provide us with the best energy reliability and availability.

It wasn't enough for our grid to have five potential generation sources – they all failed in different ways. But what if we incorporated more geothermal, which is more cold-weather resistant? What if we upgraded our solar panels to all have trackers or heating elements to prevent snow accumulation? What if our grid had access to larger scale energy storage? What if consumers had more access to off-grid distributed energy systems like generators, residential solar, geothermal pumps, or even just really large home batteries? What if we had predictive solutions that were able to detect when the non-winterized equipment would fail, days before they did? What if we could generate power from fossil fuels without dangerous emissions like carbon monoxide?

All of these technologies and more are being created and developed in our energy innovation ecosystem today, and many in Houston. What we're building towards is diversity of our energy system — but not just diversity of source — which is often the focus – but diversity of energy transportation, energy delivery, and energy consumption. Energy choice is about being able to, as a consumer, have a variety of options available to you such that in extenuating circumstances like winter storms or other catastrophes, there is no need to depend on any single configuration.

In a state like Texas, which is not only the largest oil and gas producer but also the largest wind energy producer and soon to be home to the largest solar project in the US, innovation should and will happen across all energy types and systems. Uri can teach us about the importance of the word all and how critical it is to encourage startups and technology development to develop stronger energy choice. Texas is the perfect home for all of this — and our state's rather embarrassing failure around Uri should be exactly the kind of reminder we need to keep encouraging this paradigm.

3 Houston innovators to know this week

who's who

Editor's note: In the week's roundup of Houston innovators to know, I'm introducing you to three innovators recently making headlines — from health tech founders to the new GHP chair.

Deanna Zhang looks closely at the energy innovation market and, well, last year was extremely enlightening about the energy industry and where tech is taking it. She joined the Houston Innovators Podcast last week to discuss some of the 2020 trends and observations she had — and what that means for 2021.

"The energy transition saw a huge uptick in 2020 — and there's a lot of implications of that from what pilots are getting commercialized and what companies are getting more funding," says Zhang. "All around it was hugely disruptive — but hugely beneficial I think to the energy transition." Click here to read more and stream the episode.

As great as it was to be able to begin distributing the life-saving COVID-19 vaccine, the logistics of the two-dose process was a nightmare. Dr. Sarma Velamuri, CEO of Luminare, thought he could innovate a solution. His new platform, Innoculate (a mash-up of "innovate" and "inoculate"), enables organizations like public health departments, fire departments, school systems, and businesses to manage high-volume vaccination initiatives.

"Usually when you hear news of a new batch of vaccines headed your way, there is dread at the management and distribution overhead. Not anymore," Velamuri says in a release. "Innoculate will help streamline the vaccination process in the fight against COVID-19 and allow for hundreds of thousands of people to get vaccines easily." Click here to read more.

Hey Houston, it's time to speak up — a little louder for the people in the back. That's what Amy Chonis, 2021 chair for the Greater Houston Partnership, wants you to know, and that it's important for business leaders across the city to take the initiative about how great Houston is.

"We just don't brag enough about how much the city has changed and its trajectory," she tells InnovationMap.

While Houston has long been innovative in the health, space, and energy industries, it has a perception problem. Recently, Chronis addressed some of these concerns in her address at the GHP's 2021 Annual Meeting. She joined InnovationMap for an interview to zero in on how the business community can work to change this perception problem and continue to grow its innovation and tech community.

Houston expert: 2020 was 'hugely disruptive — but hugely beneficial' for the energy transition

HOUSTON INNOVATORS PODCAST EPISODE 69

In 2020, the economy was hit with a double whammy of sorts — from a devastating pandemic to an unprecedented drop in oil prices — and that has meant that the energy transition is happening at a faster pace than ever.

Deeana Zhang, director of energy technology at Tudor, Pickering, Holt & Co., joined the Houston Innovators Podcast this week to discuss what she observed throughout the year as she worked closely with energy tech businesses.

"Because it was such a disruptive year, everyone — from the commercial and business side to the consumer side — has rethought how they are using and thinking about energy," she says on the show. "It was the first time that you saw such a mass disruption of energy demand, and that rolls through the entire ecosystem."

The effect touched all four corners of the industry in some way, and it forced all major energy players to be more intentional with their business strategy — especially when it comes to the role they play within the energy transition.

"The energy transition saw a huge uptick in 2020 — and there's a lot of implications of that from what pilots are getting commercialized and what companies are getting more funding," says Zhang. "All around it was hugely disruptive — but hugely beneficial I think to the energy transition."

Environmental, social and corporate governance, which has been growing in importance to investors and company leadership for several years now, also got a spur from 2020. ESG has been propelled by activism and consumer choice, Zhang says, but now investors are now forced to be more cognizant than ever.

"What's the investor responsibility to society as a whole? It's going beyond economics — what's your social and environmental responsibility? I think a lot of that expansion of responsibility is what's driving ESG," she says. "That's going to trickle down corporations and companies as they think about what is their expanded responsibility."

Zhang, who works closely with energy startups, also observed a profound effect when it came to capital and new business.

"A lot of companies say numbers go down in 2020, but the exceptions to that were companies that had a strong energy transition angle. Those companies were able to reposition themselves to ... counteract what was going on in the market in general," Zhang says. "From a capital raising standpoint, it was also really challenging. A lot of funds put a hold on investing in new companies and even some to their existing portfolio."

Investment came back toward the second half of the year, but there was a new level of caution, she says, and this is something startups saw happening across the country.

Zhang discusses more about what she saw happen last year for energy technology — as well as what that means for 2021 — on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

From fossil fuels to clean and sustainable energy, here's what experts postulate the industry will look like in 2050. Natalie Harms/InnovationMap

Overheard: Experts weigh in on what the energy industry will look like in 2050 at Houston summit

Crystal ball

There are a lot of things up in the air within the energy industry when you look at the next 40 years — clean energy, regulation regarding fossil fuels, carbon footprint, and so much more.

At the Society of Petroleum Engineers' inaugural SPE Dot Energy Leadership Summit, the big question was what does 2050 look like for the industry. Tasked with the discussion were three energy leaders — Deanna Zhang, energy tech investment banking associate at TudorPickering Holt & Co., Lees Rodionov, vice president of Global Stewardship at Schlumberger, and David R. Hall, managing director of Hall Labs — on a panel moderated by Gabriella Rowe, CEO of Station Houston.

The panel, which took place on August 15 at MATCH, discussed all the variables and what their potential theories are for how time will change oil and gas. Of course, no one knows for sure. If they did, they wouldn't be sharing it, would they?

"It's very hard I think to capture all the things that will play out by 2050, and honestly, if I knew with any amount of certainty what would happen, I wouldn't be talking about it in public," Zhang says. "I'd be in a basement somewhere, making a company that would make a trillion dollars."

Fair enough. Here are some other overheard quotes from the discussion in case you missed it.

“I think we’ll face the fact that we’ve got to be totally clean and solve the emissions problem and do a complete full cycle. It’ll mean lots of innovation, but I certainly see the capability to get it done.”

— David R. Hall, managing director of Hall Labs.

“When it comes to bridging the efficiency debate and the green and clean debate, that will be something that by 2050 we will have bridged.”

— Deanna Zhang, energy tech investment banking associate at Tudor Pickering Holt & Co. Currently, she says the industry is split. "Right now we are trying to optimize for two objectives. The industry is divided."

“I think that one of the challenges actually is that it’s an idea of ‘us and them,’ and energy is a ‘we.’ Everyone has a role to play.”

— Lees Rodionov, vice president of Global Stewardship at Schlumberger. She emphasized that it's the energy industry — oil and gas is just one part, and it's where there's a lot of money. O&G does have opportunities for carbon neutral development.

“The opportunity for the oil and gas industry is to recognize the problems and then announce solutions itself. If the industry doesn’t, regulators will."

— Hall says on moving the industry toward a cleaner, greener future.

“In 50 years, we’ll find a way to survive, but it won’t be the same quality of life.”

— Zhang, when asked about the worst case scenario if the industry doesn't make big changes. She cites urbanization and a greater wealth gap as some things to expect.

"Stop saying 'oil and gas.' It's 'energy.'"

— Rodionov, when asked about bridging the gap between renewables and fossil fuels.

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.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
