Houston had a strong showing at this week's SXSW Pitch showcase in Austin, with two local startups claiming top prizes in their respective categories.

Little Place Labs, a Houston space data startup, won the Security, GovTech & Space competition. Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.

As one of SWSX's marquee events, held March 8-10, the pitch competition featured 45 finalists, selected from 589 applicants, in nine categories.

"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.

Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.

Little Place Labs echoed that sentiment with a post on LinkedIn celebrating the win.

"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” the post read. "Today, that mission feels even stronger."

The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.

Tempesst Droneworx, a veteran-owned software company that provides real-time contextual intelligence for early warning detection, took home the Best Speed Pitch prize.

Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.

According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.

Houston biotech startup PHIOGEN is among 45 finalists that will present at this year’s SXSW Pitch showcase in Austin.

PHIOGEN is one of five food, nutrition, and health startups that will participate in the pitch competition, set for March 9 and 10. A panel of judges will listen to the pitches and then pick the winners. Since 2009, SXSW Pitch finalists have raised more than $23.2 billion in funding.

PHIOGEN has developed the world’s first biogenetics technology platform to harness the power of bacteriophages in the fight against serious drug-resistant infections. Bacteriophages — viruses that are found in bacterial cells — “are ubiquitous in the environment and are recognized as the most abundant biological agent on earth,” according to an article published in 2022 by StatPearls.

Founded in 2023, PHIOGEN is a spinoff of the Baylor College of Medicine’s TAILOR Labs. The startup, based at the Texas Medical Center’s Innovation Hub, has attracted more than $5 million in funding.

“Nothing about our treatments is fabricated; it boils down to creating natural environments that mimic real-life infections, driving biological changes to create ‘super phages’ against the superbugs,” Amanda Burkardt, CEO of PHIOGEN, said in 2023. “As a result, we receive high-performing phage fighters that are trained and ready to deliver safe and effective treatments for clinical applications.”

Professional services firm KPMG is the main sponsor of SXSW Pitch.

Six of this year’s SXSW Pitch judges are from Houston:

Heath Butler of Mercury Fund
Jesse Martinez of LSA Global
Trevor Purvis of the Houston Astros
Anu Puvvada of KPMG
Irene Tang of StartOut
Nate Thompson of HTX Sports Tech

“2024 is an exciting year for startups, and we are looking forward to showcasing these inspiring companies that are making waves in their respective industries and the world as a whole, as well as help connect them with the resources needed to continue advancing,” says Chris Valentine, producer of SXSW Pitch.

How this Houston-based studio is tackling billion-dollar problems with internal innovation

Q&A

In 2021, KPMG, a New York-based global audit, accounting, and advisory service provider, formed a new entity to play in the innovation space. The Houston-based team finds innovative software that benefit KPMG's clients across industries.

"We're really focused on transformative businesses that we can offer our clients in the next three to five years to solve fairly large problems," Anu Puvvada, KPMG Studio leader, tells InnovationMap.

Now, almost two years later, KPMG Studio has spun out its first company, AI-based security startup Cranium, which has raised $7 million in a seed round led by SYN Ventures with support from KPMG.

Established to advance internal innovation, KPMG Studio's technologies don't always get spun out into startups like Cranium, but with support of the team, the early-stage ideas receive guidance from the company's resources with the potential to be rolled into KPMG's suite of services for its clients.

In an interview with InnovationMap, Puvvada shares more about the program, the Cranium spin out, and why she's passionate about leading this initiative from Houston.

InnovationMap: Tell me about KPMG Studio's structure and your overall goal with the program.

Anu Puvvada: I like to think about it more around framing. We frame the studio around three pillars: incubate, accelerate and amplify. We take in a lot of ideas that come from the business and from our clients and we incubate and see which of them are really high growth solving like a very large problem across verticals and horizontals. When I say a big problem — it's got to be a $1 billion-plus problem. With Cranium, we saw some very early indicators, like a rise in AI adoption amongst our clients. We saw that AI was in this spot where it was going to hit an exponential growth marker. We also saw a rise in cyber attacks. All of that plus conversations with clients made us realize that there's there's something big brewing here.

We're looking at a ton of ideas, and then parsing out maybe 10 that we create into the next Cranium. And then in accelerate, we're finding early adopters and we're growing the idea, building it, raising venture capital for the idea if we decide to spin it out.

IM: Seems like a mutually beneficial relationship between KPMG and these innovators, right?

AP: I would say it's good for KPMG because it allows us to innovate differently and innovate with agility. My group actually operates as a startup within a large organization. And then we create this ecosystem around startups inside KPMG, so when it exits, it's got the basis to run on its own. That's important for us because it gives us agility, it lets us really capitalize on our brand. It's not just what it brings us, but also what it brings our clients.

There's a big competitive advantage to innovating inside KPMG. These innovators get to work inside our walls protected by the infrastructure of KPMG. They, they get a technology team to help them build the idea. And they get to use their brand of KPMG, use our marketing engine, our comms engine, like everything that's behind us. A startup outside, it doesn't get any of that. So, it almost like accelerates them into market when the spin out happens. We use the differentiators and the competitive advantage of KPMG in order to amplify the story of that startup and their value proposition in the market.

IM: So there are two paths for these technologies, right?

AP: We either have what we call spin ins, which means it's created and spins into the business or we have spin outs, which is what Cranium is. We classify spin outs into its own startup or a sale of an asset. And then for the spin in, we would license to our clients under the mothership of KPMG.

IM: Is the studio operating completely in Houston?

AP: We source our ideas from all over nationally. I'm in Houston and a lot of my support team is actually in Houston as well. And I work with a lot of the Houston ecosystem around innovation. I really see Houston as a big future market. We are at the center of climate and ESG, the space economy, and medicine. Those are three big like curves that are going to be hitting in the next five years. So, it is integral for studio to be integrated into that ecosystem to position KPMG for the future.

IM: What's your vision for the studio?

AP: I definitely see us taking in more ideas into studio to build internally for our pioneers, which is what we call our innovators — Jonathan Dambrot, who is the founder of Cranium, he's the pioneer. We'll definitely be doing more Craniums that spin out of the firm. And we have a number that are spinning into the firm already.

I also see us evolving to bring in external startups into the studio so we can also give them the entire ecosystem a way to be lifted up and to shepherd each other into the future.

It's really important that anything that we invest in and we work on is staying measured through these hype cycles that are happening. We need to make sure that these ideas are grounded in the problem that's being solved in an adaptable way and that there's a strong market need for it. That's something that the studio really spends a lot of time doing in the beginning, which kind of helps mitigate some of these hype cycles for us and our clients.

When you think about innovation as a whole, it's mired with risk and uncertainty. You never know if something's going to work or not. And part of what we have to do with any idea that we're building in the studio or anything that our clients are doing around innovation, we have to do as much as we can to mitigate that risk and uncertainty. And that's kind of what KPMG's wheelhouse is.

While most corporations should be optimizing their company cultures, energy companies specifically need to move the needle on driving forward innovative culture for its employees. Getty Images

Sustaining a culture of innovation is key to driving the energy industry, says this Houston expert

Guest column

The prevailing economic environment has made innovation essential to gaining a competitive edge in the oil and gas industry.

Global economic shifts and the unstable oil market have been considerable factors inhibiting the advancement of innovation in the oil and gas sector. Oil prices have not significantly increased in the past four to five years, while investors and Wall Street hold corporate executives accountable for capital discipline.

In light of these trends, corporate culture and innovation are key factors that hold the potential to drive novelty in the next upcycle. To bring value to shareholders, the oil and gas industry needs to nurture an environment that fosters a radically innovative culture to create new product lines and markets, unique ecosystems, product content, and processes.

Culture from the top down

Organizational culture is one of the essential dynamics that drive innovation. Employee behavior helps influence and promote the acceptance of innovation as a fundamental corporate value. Organizations are therefore admonished to concentrate on fostering an innovative culture that allows the growth of new ideas.

This culture needs to be created by deliberate action on the part of leaders of industry or by indirect measures such as composition and institutional policy directions. A model of innovative culture which translates into cultural transformation emerges as a result of this deliberate action and institutional policy directions.

Various studies over the years have examined innovative culture models focused on cultural characteristics or factors. A comprehensive, innovative culture model that incorporates cultural traits and their determinants is reviewed in this contemplative piece.

Execution culture vs. innovative culture

In her book, "The Culture Map: Breaking Through the Invisible Boundaries of Global Business," Erin Meyer explains that "ambidextrous culture" is the concurrent search of flexibility and alignment at a business unit/sector which is linked to several organizational outcomes including improved performance and innovation.

This ambidextrous culture can be divided into two broad categories: Execution culture and innovative culture. Execution culture is a working environment that is more process- and task-driven to get things done. The oil and gas industry has typically favored the execution culture, where there is a central decision-maker at the head of the table. Research and recommendations on pertinent matters are typically presented to decision-makers who sit through a PowerPoint presentation. Subsequently, a decision is made based on the facts presented via PowerPoint presentation.

One critical demerit of this setup is that it usually leans towards low-risk conservative judgment. The executive lifestyle has worked in the past in the oil and gas industry due to the high fixed cost, and the "failure is unacceptable" approach in the industry.

With new technologies such as 3D printing, predictive analytics, machine learning, and deep learning, one can test some ideas or thoughts through rapid prototyping in a lab setting to test their hypothesis. Therefore, this type of culture as a sole approach to decision-making in the industry may need to be reconsidered.

Meanwhile, innovative culture is a work environment where leaders encourage and nurture unorthodox thinking in approaching problem solutions and applications. If the energy industry leaned more toward this style of culture, it would help foster innovation and accelerate the innovation landscape in the industry.

Innovative culture is a more design-oriented approach that generates a large pool of options and also incorporates a visual thinking framework. It enhances a creative mode for the audience, and everybody in the company ends up being a decision-maker. This type of culture fosters open innovation, eliminates the fear of expression, and pushes for more collaboration and creativity in the ecosystem.

According to a recent survey done by Accenture Strategy, 76 percent of leaders say they regularly empower employees to be innovative, while only 42 percent of employees agree. This shows an apparent disparity in more than the perceptions of employers versus employees and the belief that innovative culture is not promoted by middle management. This barrier can be broken down by instituting and enforcing an innovative culture.

Staying agile in a transforming world

The world has changed, and it will continue to transform. Various factors are disrupting traditional methods of business management across the globe, and organizational behavior is being impacted significantly. For an organization to be competitive globally, it requires innovation and creativity.

The rate at which businesses are facing competition requires agility. Employees are pressured to give their best and to come up with new ideas at a level even beyond some of history's greatest minds. For many, uncertainty and insecurity abounds. The fear of being made redundant and a resulting lack of trust prevents creativity among employees.

Trust, productive gameplay, and fun — critical components of an innovative culture — can spark creativity and increase global competitiveness. Due to the recent downturn, most teams are burdened with the same amount of work, which was meant for double or tripled their workforce and are still expected to perform at their peak capability. They need the right conducive environment to function.

Implementing action

While the energy industry should avoid trying to copy innovative practices from technology companies, oil and gas companies should review possible case studies that can be incorporated in fostering an acceptable culture for millennials to be attracted to the industry.

Presentation is important

Take a look at your marketing materials, for instance. Skip the stereotypical image of the macho oil guy on a rig operating the brake handle and showcase how the industry is adapting open innovation across sectors such as using predictive analytics and rapid prototyping to help design a safe working environment. Showcasing the conducive culture we experience in oil and gas, which challenges us to think outside the box and solve the world's energy problems will be an excellent way to create opportunities internally in companies and also attract and retain talent from different backgrounds and industries to help solve the world's energy problems.

Consider flexible work initiatives

To help establish and foster an innovative culture in oil and gas, the industry needs to embrace virtual and remote working environments, retraining and refresher courses to keep employees' skills relevant to solving problems, leaders setting a positive example on work-life balance and cutting down or avoiding long-distance travel via virtual meetings. Others essential pointers to consider are, giving employees the freedom to be themselves at work, leadership or management having a positive attitude towards failure, allowing remote work on days on which employees have personal commitments, networking events with company leaders scheduled during office hours, having an open channel for the report of sexual discrimination/harassment incident(s) to the company, among others.

I'd like to close with a quote from another influential book, "The Innovator's Dilemma," by Harvard Professor Clay Christensen. He writes, "When an organization's capabilities reside primarily in its people, changing to address new problems is relatively simple. However, when the capabilities have come to live in processes and values and especially when they have become embedded in culture, change has become extraordinarily complicated."

Establishing a uniquely innovative culture within the energy industry will be a great foundation going forward, for spurring progress in the oil and gas sector.

Recently, Houston got a "needs improvement" on its coworking space report card — but the tide is changing as more and more coworking spaces plan to open in town — especially in the downtown sector.

Houston's current coworking space volume ranked it No. 15, according to a report from Colliers International, which fell behind Dallas and Austin. However, Houston has many future projects due to deliver in the next 18 months or so — including over 100,000 square feet of space in downtown alone. Continue reading the story.

Houston entrepreneur launches an app that matches patients to their ideal therapist

Ryan Schwartz realized online dating was easier than finding a therapist. He created a tool to change that. Courtesy of Mental Health Match

Nearly five years ago, Ryan Schwartz sat in a coffee shop in crisis mode. His mother had just died suddenly and he was struggling to find an appropriate therapist. Across the table, his friend sat making a profile on a dating app. Quickly, her endeavor was complete and she was ready to swipe right, but Schwartz was still on the hunt for mental help.

"In two minutes she could have a profile matching her with a partner potentially for the rest of her life and I was sitting there for hours and hours trying to find a therapist," he recalls. "I thought it should be easier to find a therapist than a life partner. That's what sent me on my journey."

That journey reached a watershed last month when Schwartz launched Mental Health Match, a website designed to pair patients with their ideal therapist. The idea gained traction as Schwartz described it to people he met and found that many said they had experienced similar difficulties in finding the right practitioner for their needs.

Overheard: Oil and gas experts weigh in on the future of low-carbon energy and Houston's role in the movement

Eavesdropping in Houston

As the energy capital of the world, Houston can't get complacent. The oil and gas industry is changing — carbon is out and finding clean energy alternatives is in.

In case you missed it, here are a few powerful quotes from both days of the program — from Houston's role in the low-carbon energy movement to Tillerson's leadership expertise.

"Texas is one of those places where you can just get stuff done.”

— Cindy Yeilding, senior vice president at BP, says Texans are willing to collaborate on this. In the "Visions of our Energy Future" panel during the Low Carbon Energy Summit on Thursday, June 6, she predicted Houston will be a net zero carbon city by 2040 or 2035.

“One of the things we need to focus on is being able to attract and retain talent.”

— Mary Anne Brelinsky, CEO of EDF Trading, stressing the importance of talent in the effort to keep Houston the energy capital of the world. Brelinsky advocated for corporations and its execs getting involved with local universities. "We're competing against Silicon Valley," she says in the panel.

"You’ve got the source, and you’ve got the sinks. … Houston is going to be one of our focal points.”

— Charlene Olivia Russell, vice president of Low Carbon Strategies at Oxy, on how Houston is set up for success when it comes to staying as a power player in the global low carbon energy platform, but, during the panel, she emphasizes collaboration needs to continue happening.

“When Shell agreed to sponsor this summit, it was pitched as a climate change summit. It was changed to a low-carbon summit because some people in this room are uncomfortable with the phrase 'climate change.'"

— Jason Klein, vice president of U.S. Energy Transition Strategy at Shell, says at the "Energy Transformations" panel during the Low Carbon Energy Summit on Thursday, June 6.

"If we want to be the leader and the energy capital of the world, we need to attract talent, capital investment, and innovation, and if the people are going to do those things think that we don’t even like to talk about those things, then they aren’t going to come here — they’re going to go to San Francisco.”

— Klein continues. The audience responded with a round of applause.

“I think it is important as Americans to remember that our greatest strength and the most important element to our national security has been that we are a nation that has many allies and friends. Our adversaries — Russia, China, North Korea, Iran — have no allies or friends.”

— Former Secretary of State Rex Tillerson who served as CEO of ExxonMobil from 2006 to 2016. Tillerson discussed a wide range of topics on Wednesday, June 5, at the 2020 KPMG Global Energy Conference in his fireside chat with Regina Mayor, global sector head and U.S. national sector leader of energy and natural resources at KPMG US. Click here to watch the full interview.

“We’re all a work in progress. You’re never done. I’m not done — I’m still a work in progress. If you have that view and you have that set of values that are never going to change … [then] I can keep developing as a human being.”

— Tillerson says of leadership lessons learned. He's an avid proponent of the Boy Scouts of America organization, and cited many valuable lessons he's learned about himself and about leading people from his involvement in the nonprofit.

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.

Casimir

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. 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.

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