3+ Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes an energy leader, an electric vehicle expert, and more.

Ana Amicarella, CEO of EthosEnergy

For most of her career, Ana Amicarella has been the only person in the room who looks like her. But as CEO of Houston-based EthosEnergy, she's changing that.

"The energy sector for sure is highly dominated by men, but I think it's such an exciting environment," Amicarella says on the Houston Innovators Podcast. "What I try to do at every job that I go to is I try to increase representation — diverse representation and females in the company. And I measure that when I started and when I end. I want to be able to make a difference."

Amicarella joined EthosEnergy — which provides rotating equipment services and solutions to the power, oil and gas, and industrial markets — as CEO in 2019 a few years after it was in 2014 as a joint venture between John Wood Group PLC and Siemens Energy AG. Prior to her current role, she served in leadership roles at Aggreko an GE Oil and Gas. Read more.

A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Houston-based Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth." Read more.

As Texans continue to invest in electric vehicles, public charging needs to be able to meet an increased demand, according to Chris George, the United States co-lead at Octopus Electric Vehicles, who wrote a guest column for InnovationMap about the state's potential when it comes to EVs.

"As we look to the future of transport and energy, the synergy between NEVI and Tesla’s network should create a compelling narrative for those thinking about leasing an EV," he writes. "Combine that with exciting new battery tech and potential range improvements, fueled by West Texas wind and solar, Texas is positioned to be a great state for the EV industry." Read more.

fresh funding

A Houston company has closed its series B extension at $25 million.

MetOx International, which develops and manufactures high-temperature superconducting (HTS) wire, announced it closed a $25 million series B extension. Centaurus Capital, an energy-focused family office, and New System Ventures, a climate and energy transition-focused venture firm, led the round with participation from other investors.

"MetOx has developed a robust and highly scalable operation, and we are thrilled to partner with the Company as it enters this pivotal growth stage," says John Arnold, founder of Centaurus, in a news release. "The market for HTS is expanding at an unprecedented pace, with demand for HTS far outweighing supply. MetOx is poised to be the leading U.S. HTS producer, closing the supply gap and bringing dramatic capacity to high power innovations and applications. Their progress and potential are unmatched in the field, and we are proud to support their growth."

The fresh funding will go toward advancing the company's Xeus HTS wire technology for key energy transition applications by expanding MetOx's U.S.-based manufacturing capabilities to meet demand.

"This funding marks a pivotal step in our mission to revolutionize the energy and technology sectors with our advanced power delivery technology and accelerate delivery for our customers and partners. HTS is critical to enhancing the efficiency of our electric grid and enabling technological developments that, in many cases, would not be viable or even possible without superconductor technology," adds Bud Vos, CEO of MetOx. "Support from investors such as Centaurus and NSV not only provides the financial resources and strategic support required for accelerated scaleup, but also validates the broad reach of our technology across energy, data center, medical, and defense industries."

HTS wire technology is critical for the energy transition, especially amid rising data center growth, and for next generation wind turbines and interconnections.

MetOx's technology originated out of the University of Houston and was founded in 1998 by Alex Ignatiev, UH professor emeritus of physics and a fellow of the National Academy of Inventors. Last year, the company secured $3 million in funding from the U.S. Department of Energy to support the advancement of its proprietary manufacturing technology for its HTS wire.

"MetOx's HTS technology aligns with our systems-level research and offers a unique opportunity to dramatically accelerate the energy transition," says Ian Samuels, founder and managing partner at NSV. "MetOx's Xeus wire stands to be a force multiplier in clean energy generation and high-power transmission and distribution, enabling load growth and the deployment of power-dense data centers. NSV is excited to support MetOx as it scales domestic manufacturing capacity."

Local billionaires Jeffery Hildebrand and Tilman Fertitta top list of richest in Houston, per Forbes

meet the billionaires

According to Forbes, half of all of the world’s billionaires are less wealthy than they were in 2022. But that’s not the case for most Houston-area billionaires like oil tycoon Jeffery Hildebrand, who was named the richest man in the city.

The 2023 edition of Forbes’ World’s Billionaires List declared Hildebrand’s net worth at $10.2 billion, placing him as the 171st richest person in the world. His fortune is $2.7 billion higher than his 2022 net worth of $7.5 billion, when he ranked No. 316 on the list.

As CultureMap reported, in 2015, Hildebrand made headlines when he gifted each of his 1,381 employees a $100,000 holiday bonus.

Houston’s favorite hospitality mogul and Rockets owner Tilman Fertitta is the city’s second-richest man, with his net worth climbing up to $8.1 billion. He ranked No. 256 on Forbes’ list, substantially higher than his No. 471 rank in 2022 when his net worth was $5.6 billion. Fertitta is surely living life to the fullest after hosting Miami rapper Pitbull at his San Luis Salute celebration earlier this year.

Other Houston-area billionaires that made Forbes 2023 world’s richest list are:

  • Pipeline magnate Richard Kinder: tied for No. 317, $7.2 billion, down from $7.5 billion
  • Houston siblings and pipeline heirs Dannine Avara, Scott Duncan, Milane Frantz, and Randa Duncan Williams: all tied for No. 352, $6.8 billion, up from $6.6 billion
  • Toyota mega-dealer Dan Friedkin: tied for No. 466, $5.5 billion, up from $4.3 billion
  • Houston Texans owner Janice McNair: tied for No. 534, $5 billion, up from $4.2 billion
  • Hedge fund honcho John Arnold: tied for No. 878, $3.3 billion, unchanged since 2018
  • Energy exploration chief exec George Bishop: tied for No. 982, $3 billion, up from $2.7 billion
New to the 2023 report is Kamal Ghaffarian, the co-founder and executive chairman of Houston's Axiom Space, with a net worth of $2.1 billion. Though his LinkedIn notes that he is based in Maryland, reports add that he resides in Florida. His Forbes rank is No. 1434.An honorable mention (and billionaire newbie) is Amy Adams Strunk, the controlling owner of the Tennessee Titans and daughter of Houston Oilers owner Bud Adams. She has a residence in Waller (about 40 miles northwest of Houston) and her net worth is $1.7 billion — making her No. 1725 on the list.One name missing from Forbes 2023 report is software entrepreneur Robert Brockman, who passed away last August. Brockman fell from grace after he was charged in the largest tax fraud case in U.S. history in 2020. Forbes listed his 2022 net worth at $4.7 billion. He is survived by his wife, son, and two grandchildren.Elsewhere in Texas, Elon Musk reigns as the richest man in the state and in its capital city of Austin with a net worth of $180 billion. The Tesla and Space-X founder is the second richest person in the world, wedging his way between No. 1 Bernard Arnault of France (overseer of the LVMH empire of 75 fashion and cosmetics brands, including Louis Vuitton and Sephora), with a net worth of $211 billion; and No. 3 Jeff Bezos, the American Amazon founder, worth $114 billion.

Dallas Cowboys owner Jerry Jones'$13.3 billion net worth won him the title of Dallas' richest person, and the 12th richest sports owner on Forbes' "World's Richest Sports Owners 2023." His net worth is up from $10.6 billion last year.

The Fort Worth-based Walmart family heiress Alice Walton earned a spot on Forbes’ list as the third richest woman in the world. Her fortune is pegged at $56.7 billion, down slightly from $65.3 billion last year.

4 Houstonians join Texas Business Hall of Fame

Leading texans

The Texas Business Hall of Fame Foundation has inducted six new Texans to its prestigious ranks — and four run their businesses from the Bayou City.

John Arnold, Ric Campo, Jeffery D. Hildebrand, and Paul W. Hobby — along with Austin-based Whitney Wolfe Herd and Dallas-based Thomas O. Hicks — will be honored at Texas Business Hall of Fame Foundation's 40th Anniversary and Induction Dinner on on November 3.

“The Texas Business Hall of Fame is pleased to announce its six inductees for 2022," says TBHF Chair Amanda Brock in a news release. "Inductees are recognized as trailblazers in business and exemplary leaders who have made significant contributions in their local communities and beyond, through both philanthropic and civic engagement. Although inductees can be nominated by anyone from the general public, they are selected by their peers and determined by a majority vote by Hall of Fame members."

The TBHF honors business leaders across the state by celebrating and telling their stories. The organization also runs the Future Legends Scholar & Veteran Award Program that grants forty $15,000 awards to scholars and veterans who demonstrate entrepreneurship and innovation at 24 universities throughout the Lone Star State. Both the scholars and the six honorees will celebrated this fall.

“The selection process, combined with the organization’s emphasis on both economic and social impact makes this one of the most prestigious business honors in the state,” says TBHF Legend and the 2022 Master of Ceremonies, Richard Fisher.

Here's more information on this year's honorees:

10 Houston billionaires bank spots on Forbes' 2020 list of richest Americans

show me the money

In a booming, opportunity city full of tycoons, which billionaire reigns supreme? That honor goes to Richard Kinder, the pipeline mogul worth $6.2 billion — who is also a familiar name in philanthropic circles as a chief benefactor of Memorial Park. Locals may also recognize his name on the new Museum of Fine Arts, Houston building.

Kinder, and his wife, Nancy, join an impressive list of Texans on the 2020 edition of the Forbes 400, which ranks the 400 richest Americans and was released September 8. (See their methodology here.) "Pandemic be damned: America's 400 richest are worth a record $3.2 trillion, up $240 billion from a year ago, aided by a stock market that has defied the virus," Forbes writes.

Around Houston, the richest-of-the-rich list looks similar to recent years. Here's how local billionaires rank nationally in 2020 and how their wealth has fared:

Houston:

  • Richard Kinder — $6.2 billion, No. 103. Last year: $7.5 billion.
  • Pipeline heirs Dannine Avara, Scott Duncan, Milane Frantz, and Randa Duncan Williams — $4.8 billion each, No. 139. Last year: $6.3 billion.

  • Houston energy executive Jeffery Hildebrand — $3.6 billion, No. 222. Last year: $3.8 billion.
  • Former hedge fund manager John Arnold — $3.3 billion, No. 249. Last year: $3.3 billion.

Meanwhile, Walmart heiress Alice Walton of Fort Worth has retained her status as the richest Texan and America's richest woman in 2020, with a net worth estimated this year at $62.3 billion. That compares with $51.4 billion in 2019.

Walton moved up from No. 11 last year to No. 10 this year in the Forbes ranking of the richest Americans.

From 2019 to 2020, Walton's net worth jumped by $10.9 billion. To give you an idea of how much money that is, the size of the economy in Africa's Republic of Congo totaled $10.8 billion in 2019.

5 Houston deep tech startups pushing the boundaries of their industries

meet the finalists

Houston has long been at the forefront of innovation, from NASA’s Johnson Space Center to its startup ecosystem using technology to disrupt industries.

As part of the 2026 Houston Innovation Awards, our Deep Tech Business category will honor an innovative startup providing technology solutions based on substantial scientific or engineering challenges, including those in the AI, robotics and space sectors.

Five deep tech companies have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

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.

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.
