Clinching unicorn status with its 2023 series C raise, Cart.com is on a mission to unify commerce across sales and distribution channels and digital and physical capabilities with its omnichannel enterprise-grade software, services and logistics.

Founded in 2020 with nine acquisitions and $759.2 million raised to date, according to Crunchbase, Cart.com's recent achievements includes acquiring Pacsun’s fulfillment operators, brining a 2 million-square-foot facility online, expanding its executive team, and more.

"In the last 12 months, Cart.com has dramatically grown its fulfillment network’s scale and technological capabilities," writes CEO Omail Tariq in his Houston Innovation Awards application.

"We have been laser-focused on improving quality, performance and efficiency at scale while continuing to aggressively grow our customer base, expand our capabilities to customers in new industries and grow our physical presence to new locations," he continues. "Prioritizing our strategic growth initiatives has been critical in the current macroeconomic environment as profitable growth remains paramount for our team."

In 2021, Cart.com moved its headquarters to Austin, with most of the leadership team remaining in Houston. Two years later, the company announced its HQ return to the Bayou City.

"We've found Houston's business and university communities to be incredibly supportive of our efforts and have found the city to be a place that is both easier and more affordable to bring together our global employee population at more regular intervals," Tariq adds in the app.

Revolutionary biotech company Coya Therapeutics Inc. (NASDAQ: COYA) may have closed its IPO in January 2023 for more than $15 million, but the company has made some of its most significant strides in the development of its lead product that prevents the further spreading of neurodegenerative diseases this year.

Known as COYA 302, the product uses a unique dual mechanism that is now being developed for the treatment of Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD), Parkinson’s disease and Alzheimer’s disease. The company published its phase 1 proof-of-concept study in the peer-reviewed journal Frontiers in Neurology that showed COYA 302's ability to stop clinical progression in ALS at 24 weeks in combination therapy, which helped earn the company a $5 million in strategic investment from the Alzheimer’s Drug Discovery Foundation to continue to develop the product for a planned Phase 2 trial focused on FTD.

Last year the company also added to its C Suite, naming Dr. Arun Swaminathan as chief business officer and Dr. Fred Grossman as president and chief medical officer.

Coya merged with Nicoya Health Inc. and raised $10 million in its series A in 2020.

NanoTech Materials, a chemical manufacturer that integrates novel heat-control technology with thermal insulation, fireproofing, and cool roof coatings to drastically improve efficiency and safety

Growing Houston startup moves into 43,000-square-foot facility amid 'hypergrowth phase'NanoTech Materials celebrated its move into a new facility — a 43,000-square-foot space in Katy, Texas, this week

Mike Francis, co-founder and CEO of NanoTech Materials, told InnovationMap earlier this year that it was in a "hype growth" phase—and meant it.

NanoTech, known for its proprietary Insulative Ceramic ParticleTM (ICP) that uses nanotechnology to optimize energy efficiency and heat control in the built environment, expanded into a new 43,000-square-foot facility this year and tripled its valuation in the last two years, according to its Innovation Awards application. The company also expanded into the Middle East and Singapore and successfully scaled up its NanoTech Cool Roof Coat to commercial markets.

The company closed a $5 million seed round in 2020 and an oversubscribed Series A round last year for $13 million. It was the first company selected for the Houston-based Halliburton Labs in 2021 and joined the Rice Alliance Clean Energy Accelerator in 2023.

Submersible robotics company Square Robot launched its Houston office in 2019 and expanded in the Bayou City this past year.

According to the company's Innovation Award application, the company doubled its fleet of autonomous, submersible robots that service the energy industry, deploying to Malaysia, Vietnam, Thailand, Australia, Kuwait and Saudi Arabia. Its robots are specifically used for storage tank inspections and eliminating the need for humans to enter dangerous and toxic environments.

Square Robot moved to a new, customer-facing Houston facility this year and also developed a new innovative technology that's able to gather phased ultrasonic readings on insulated tank shells while the tank is operational.

The company closed a Series A round in 2018 for $6 million.

Known for the world’s first light-powered reactor cell for industrial chemical reactions, Syzygy Plasmonics began taking orders earlier this year for its Rigel reactor cell after meeting initial performance targets. The cell enables a customer to produce up to five tons of low-carbon hydrogen per day.

The groundbreaking technology earned the company regional, national and global attention. Fast Company magazine placed the company on its energy innovation list. It was also named a finalist for Ernst & Young’s Entrepreneur Of The Year 2024 Gulf South Award and was invited to participate in Gastech's global entrepreneur competition.

The company most recently raised $76 million in a Series C round in 2022.

Oxy's $1.3B Texas carbon capture facility on track to launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.

New app by Sports Illustrated grants access to 700 sports courts in Houston

Goal!

A new sports center booking app CatchCorner, powered by Sports Illustrated, enables sports enthusiasts in Houston to seamlessly secure a spot for a quick game without membership fees.

It soft-launched in Houston this spring and, according to co-founder and chief operating officer Maya Azouri, has been a huge success.

"The Houston expansion has been jaw-dropping," she said. "Up until now, CatchCorner’s launch in New York City had been our most successful market, but Houston has launched on par with it."

Within a 30-day period this summer, over 30,000 users join the app, Azouri noted, adding that the app would include 700 unique recreational spaces users can choose from in the city.

"There’s a real sports culture here, with athletes of all levels from casual weekend players to competitive amateurs and even pros. The diversity of the sports community, combined with the number of high-quality facilities across the city, makes it a perfect fit for CatchCorner," she said.

CatchCorner in Houston offers bookings for basketball, volleyball, soccer, pickleball, padel, baseball, badminton, and tennis, with plans to include golf simulators and ice rink sports soon. The Zone Sports, Toros HTX, PAC Gym, and Houston Pickleball Center are among the most popular venues.

Using the app is a snap. Once you pick your sport, venues with available slots are listed including distance from you with the booking schedules in the results so there are no surprises. The slots can go fast, so occasional error messages pop up when trying to book, but it's otherwise a three-click process. CatchCorner also helpfully includes a picture of the facilities while booking.

CatchCorner announced Google integration in June that lets users book through the app directly from searches when they look up specific venues. This is slightly less intuitive to use than the app, but it does ultimately work in both mobile and desktops versions. Either way, it greatly streamlines the booking process for people who just want to schedule a quick pickup game somewhere.

"It’s especially useful for casual players or people who want to organize something on short notice," said Azouri. "Whether it’s a weekend basketball run, a weekday futsal match, or a spontaneous pickleball game with friends, CatchCorner makes it easy to coordinate without the usual logistical headaches.

"Some feedback here has been that we’re like 'Expedia for sports.' It’s because booking a flight online is that easy, booking your next game or workout should be just as simple."

10 Houston billionaires make Forbes' list of richest Americans in 2025

The Rich List

America's wealthiest billionaires are $1.2 trillion richer in 2025, bringing their collective worth to a staggering $6.6 trillion. And Houston's own Richard Kinder has become the richest billionaire in the city, according to the new Forbes 400.

The Kinder Morgan chairman is the 11th richest Texas resident and ranks as the 108th richest American. Kinder also dethroned Tilman Fertitta to claim the title as the wealthiest Houstonian.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies.

Kinder's wealth

The publication estimates Kinder's net worth at $10.6 billion, up from $8.1 billion last year. He also appears among Forbes' separate list of the richest billionaires in the world.

"It’s been a year unlike any we’ve seen in the four decades we’ve tracked America’s billionaire class,” said Forbes senior editor Chase Peterson-Withorn in a press release. "The super-rich at the very top are richer than ever — and between the White House and the booming stock market, they’re as powerful as they’ve ever been."

Kinder, 80, co-founded oil and gas pipeline firm Kinder Morgan in 1997, which is now known as one of the largest American energy infrastructure companies. He stepped down as CEO in 2015, though he still chairs the board of directors.

Kinder and his wife, Nancy, also founded Houston-based nonprofit the Kinder Foundation in 1997. The organization provides "major gifts to public causes with the intention of helping people realize healthy and rewarding lives," according to its website.

In May 2025, the Kinders pledged $150 million to Texas Children's Hospital and MD Anderson to create the Kinder Children's Cancer Center.

"Our philanthropic efforts center on supporting transformational projects in Houston, and this initiative exemplifies that mission in every way," said Kinder in a press release. "We were deeply impressed by the extraordinary leadership and unwavering commitment of both UT MD Anderson and Texas Children’s to pursue a bold, collaborative model of care. It is a rare and powerful moment when two leading organizations come together to create something entirely new – something capable of reshaping the future of pediatric cancer care."

The richest Houstonians

In all, 43 Texas billionaires made it on the 2025 Forbes 400 list, and 10 are based in the Houston metro.

Hospitality honcho Fertitta, 68, is the second-richest billionaire in Houston, and his net worth has jumped from $10.1 billion last year to $11 billion in 2025. He owns the Golden Nugget Casinos, the Houston Rockets, Texas-based restaurant and entertainment company Landry's, and also serves as the U.S. Ambassador to Italy.

"Serving as President Trump's ambassador to Italy 'is a real job,' says Fertitta, who personally oversaw the renovation of Villa Taverna, the ambassador's residence in Rome," Forbes wrote in his profile.

Fertitta most recently put his ritzy 250-foot-long superyacht on the market for about $192 million, with Forbes saying he "has a bigger one on order."

Here's how the rest of Houston's billionaires fared on this year's list:

Oil tycoon Jeffery Hildebrand ties for No. 123 nationally with an estimated net worth of $10 billion. Last year: $7.6 billion.
Toyota mega-dealer Dan Friedkin ranks 128th nationally with an estimated net worth of $9.7 billion. Last year: $7.6 billion.
Houston pipeline heir Randa Duncan Williams ranks 130th with an estimated net worth of $9.5 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 135th nationally. Each has an estimated net worth of $9.4 billion. Scott Duncan ranks No. 141 with a $9.2 billion estimated net worth.
Houston Texans owner Janice McNair ranks 201st nationally with an estimated net worth of $7.3 billion. Last year: $6.2 billion.
Energy exploration chief exec George Bishop of The Woodlands ranks No. 325 with an estimated net worth of $4.7 billion. Last year: $5 billion.

Richest billionaires elsewhere in Texas

The richest person in America in 2025 is none other than Austin-based Elon Musk. Musk, 54, saw his net worth skyrocket to $428 billion this year, or $184 billion more than his 2024 net worth. He claimed the No. 1 spot for the fourth time.

Walmart heiress Alice Walton of Fort Worth was dubbed the wealthiest woman in America for 2025. Walton, 75, simultaneously holds the title as the richest woman in the world. Forbes estimates Walton's net worth at $106 billion (up from $89.2 billion last year) and proclaims her as the first female centibillionaire (a person with a 12-digit fortune) in America. Now that's wealth.

"Tariffs. Inflation. Slowing employment. None of it has hit the fortunes of America’s billionaires," Forbes said. "A decade ago, when it took $1.7 billion to make The Forbes 400, a net worth of $3.8 billion was comfortably within the top half of the ranking — now that lofty sum is the minimum required."
