A Houston startup that retrofits windows with smart glass innovations to reduce energy use has raised its first round of funding.

INOVUES closed its seed round at $2.75 million last month. The oversubscribed round was led by Dallas-based Paulos Holdings with participation from new and existing investors, including Houston-based VC Fuel, Saint-Gobain NOVA, Fund4SE, Momentum Glass, Lateral Capital, E8 Angels, and the Central Texas Angel Network.

"Our mission is to help cities achieve their energy efficiency and emissions-reduction targets by increasing the rate of window upgrades in existing buildings," says INOVUES founder and CEO, Anas Al Kassas, in a news release. "To achieve that, we have developed a low-carbon, high-ROI retrofit solution that makes upgrading building windows a financially attractive energy conservation measure instead of a massive capital upgrade associated with business disruptions and prohibitive payback periods."

Up to 40 percent of the energy loss in buildings comes from windows, per the release, and buildings as a whole represent the largest energy-consuming sector. The climatech company's patented Glazing Shield system provides a lower cost and less intrusive solution to complete window replacement.

"INOVUES is a game-changer in the energy efficiency market because it has developed an innovative, patented building retrofit solution that significantly reduces the energy usage and carbon emissions of existing buildings at a fraction of the cost of more expensive standard building retrofit options," says Ahmad Atwan, founder and CEO of VC Fuel, in the release. "We are excited that INOVUES has been recognized as the industry leader by winning prestigious green building awards on both domestic and international levels. At a time when cities are encouraging, and sometimes mandating, building owners to reduce energy consumption and carbon emissions, INOVUES has become the logical solution to such challenges."

The fresh funding will go toward growing the INOVUES team, expanding commercialization efforts, and scaling its technology.

"INOVUES' technology can radically shrink the carbon footprint of 20th-century buildings and help commercial real estate owners meet their sustainability and ESG goals with no tenant disruption and in many cases with payback periods of less than five years plus incentives," says John Paulos, vice president of Paulos Holdings, in the release. "It is exciting for us to be a part of the journey INOVUES is taking to mitigate climate change and accelerate the transition to a sustainable cleaner world."

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from health tech to energy venture capital — recently making headlines in Houston innovation.


Pamela Singh, co-founder and CEO of CaseCTRL

When COVID-19 shutdown all elective surgeries, Pamela Singh didn't know what would happen to her startup, CaseCTRL, which uses AI to optimize surgery scheduling. But, the back and forth nature of surgeries being allowed then not made for a huge need for CaseCTRL's platform to help medical facilities get back on track.

"COVID has had some sort of silver lining for us," Singh says, explaining that surgical facilities were looking for a way to catch up. "They realized the need for automating and streamlining their practice. And they realized that, instead of spending another four hours coordinating with patients and vendors, they could literally do it with the click of a button."

Singh shares more about her entrepreneurial journey and what's on the horizon for CaseCTRL, as well as her advice for fellow female founders in the podcast. Click here to read more and stream the full interview.

Ahmad Atwan, founder and CEO of VC Fuel

When Ahmad Atwan decided he was going to launch VC Fuel, a venture capital fund focused on early-stage energy transition startups, deciding where to start was easy. While there are similar funds on each of the coasts, Atwan learned that VC Fuel's concept was going to be kind of niche for Houston.

"Houston is the undisputed energy capital of the world," he tells InnovationMap. "So to me, especially when you're looking at energy transition sectors that have to work with the energy industry, it was a no brainer."

Atwan shares more about VC Fuel and the $100 million fund, which he's still raising for while also investing in a few startups at the same time, in an interview with InnovationMap. He also discusses how his expertise as a former founder and former private equity investor with Morgan Stanley and BlackRock makes him an opportune value-add investor. Click here to read more.

Maggie Segrich co-founded Sesh Coworking and the duo opened its first space in early 2020. Now, 18 months later, Sesh is growing. The female-founded, female-focused coworking company has also launched a crowdfunding campaign to support Sesh's growth.

The new coworking space is set to be in Midtown, but Sesh hasn't yet announced the specific location. The plan is to open to members at the beginning of 2022. The move will allow Sesh to offer private offices and dedicated desks, as well as other amenities members are looking for.

"Sesh never set out to be like other coworking spaces," she says. "We are on a mission to create a work space that isn't just four walls and a door. We began in 2017 by building our community first through pop-ups and then with our current space in Montrose. This new space carries on that tradition and mission of putting community first."

Houston investor launches fund to fuel early-stage energy transition startups

Q&A

When Ahmad Atwan decided he was going to launch a venture capital fund focused on early-stage energy transition startups, Houston was a no brainer. But while there are similar funds on each of the coasts, Atwan learned that VC Fuel's concept was going to be kind of niche for Houston.

"We're the only early stage climate tech or energy transition firm in Houston right now, which is really surprising," Atwan tells InnovationMap, explaining that the Bay Area is home to dozens of these funds and there are even more on the East Coast. "I'm hoping there'll be more (similar funds in Houston), but it's also kind of a nice position to be in."

Atwan shares more about VC Fuel and the $100 million fund, which he's still raising for while also investing in a few startups at the same time, in an interview with InnovationMap. He also discusses how his expertise as a former founder and former private equity investor with Morgan Stanley and BlackRock makes him an opportune value-add investor.

InnovationMap: Why did you decide to start VC fuel?

Ahmad Atwan: I decided to start VC fuel because I've been in the energy industry my entire career. I've been both an entrepreneur — I started two companies in the 2000s that I sold. One was a energy technology firm and one was a Brazilian ethanol company.

After that I was on the buy side buying pretty large private energy companies — anywhere from the size of $500 million to $2 billion. And over that whole time, energy was a very exciting industry and was growing very fast.

But as I saw climate change happening more rapidly and becoming more of a reality, and as I started looking and investing in some renewable energy sources, like wind and solar, I realized that's really where my passion was and what I wanted to do. And at the same time, the world was moving towards that as well, and investors really wanted to have exposure to new energy or energy transition areas.

IM: What are you looking for in potential investment opportunities?

AA: The areas that we focus on are all decarbonized and kind of all across the board, ranging from clean agriculture, hydrogen, carbon capture and storage or carbon capture and usage, to energy efficiency, clean industrial processes, and more. And I think these are areas that they right now comprise less than 2 percent of the global energy mix, but they're going to be north of 10, 15, 20 percent over time. So, these are high growth areas, and they are either lower, zero, or even negative emissions.

We're looking specifically for companies that we call seed stage or series A, generally, sometimes series B. So, they're companies that are relatively early in their development, but have some sort of commercial traction. And ones that are looking for not only a venture capital firm, but someone that can be their partner and help guide them and help them in certain areas, like raising their next round of funding, helping them get introduced to customers.

IM: With your experience, what do you feel like you bring to the table as a hands-on investor?

AA: I think in my decade-plus in private equity, when I was an investor on the boards of a company, I always tended to be one of the most involved in helping guide operations and working with senior management. And I think that's probably because I was a founder in the past, so I really identify with founders and I try to figure out with them what's the gap in their skillset or knowledge base that needs to be filled. Sometimes it's one that I can naturally help fill, which might be on the financial side or on the commercial side. And sometimes it's just bringing in other experts to help the company out.

But I think having been both on the founder and the private equity side, I think I empathize with the founder usually. And I would give this advice to all founders out there: the most important relationship they're going to have is with their lead venture capitalist, because that's going to be the defining relationship that helps them get to legitimacy in terms of the next round of funding. It's something that I kind of learned from friends in Silicon Valley. It's not only building the relationship for VC fuel — it's building a relationship with one of the individuals in our firm, whether it's me or one of my partners, and having them be really invested in the company.

IM: Why did you decide on Houston for VC Fuel's HQ?

AA: First of all, Houston is the undisputed energy capital of the world. So to me, especially when you're looking at energy transition sectors that have to work with the energy industry, it was a no brainer. For a lot of the technologies we deal with — like carbon capture — and the businesses we deal with, it's going to be essential for them to connect with the energy world.

I think a second reason, frankly, and I didn't realize this until we really got deep into the idea is that we're a little bit unique and we have a little bit of a competitive advantage. There are over 30 climate tech firms in the Bay Area, and there are a large number as well in New York and Boston. We're the only early stage climate tech or energy transition firm in Houston right now, which is really surprising. And I'm hoping there'll be more of those, but that's also kind of a nice position to be in because, as we see opportunities come out of the energy companies, and as we try to attract talent and grow, we think we have a pretty unique offering.

IM: What has being located in Greentown Houston meant for you?

AA: It's been fantastic. I think Houston did a great job of attracting Greentown here as the second location. Working out of here, we're able to interact in real time with everything from startup companies to major corporations. You get such a diverse set of people who are passionate about energy transition. It's actually already led to some opportunities to invest in, as well as to connect with some of the bigger companies that want to invest with us. It's been just a great coincidence that we launched here when Greentown opened. We'd much rather be here than any other type of working space. So, we're very excited.

IM: What keeps you up at night as it pertains to the energy transition?

AA: I would say the first thing is commercial adoption. All of our companies so far have great management teams — especially founders — and excellent technology, but there's that bridge to actually get the technology adopted by a customer. Sometimes you can have the best technology, and it just never happens. So, I'm keeping my eye on how much progress are we making with commercial customers. A lot of these are big companies — whether it's a waste management or a tech company, like a Microsoft — are getting into energy transition. Customer adoption in that area is a key metric for us.

The second big one — and this one's a little newer to me because I didn't face it as much in the past — is regulation. So many of the areas that we look at are going to have their economics determined by regulations that are literally being written right now. For example, the Cares Act the by the Biden administration is deciding things like what the level of tax credits will be for carbon capture. The carbon capture company we've invested in suddenly sees their projects become a lot more profitable if that figure is on the higher side. It's important to keep our ear to the ground on regulation and try to anticipate where it's going. That's why we have a couple people who are ex-Department of Energy on our advisory board because we like to have that skill set.

IM: What's next for VC Fuel?

AA: Our cadence of investing is that we invest in about one company every couple of months, which is pretty fast for a venture capital firm in energy transition. What's next is for our current companies to get to the next stage of evolution. There is one that I can't talk about specifically, but it might be getting sold to a really exciting buyer — and it's very good to have that kind of exit early on in a fund's life. And for the rest of our portfolio companies it's about continuing to get customers and next rounds of funding.

We've done a really good job of building a portfolio. That's not concentrated in any one area of energy transition. We will continue to look for a diverse set of companies that compliment each other, and that can help each other out. One area we continue to look at is not just the carbon capture, but also the carbon use space where you can turn carbon into something that's actually productive. Another area that we continue to look at is the electric vehicle space, but not just traditional EVs, but the next generation EV technology.

U.S. News names 5 Houston suburbs as the best places to retire in 2026

Retirement Report

Houston-area suburbs should be on the lookout for an influx of retirees in 2026. A new study by U.S. News and World Report has declared The Woodlands and Spring as the fourth and fifth best cities to retire in America, with three other local cities making the top 25.

The annual report, called "250 Best Places to Retire in the U.S. in 2026" initially compared 850 U.S. cities, and narrowed the list down to a final 250 cities (up from 150 previously). Each locale was analyzed across six indexes: quality of life for individuals reaching retirement age, value (housing affordability and cost of living), health care quality, tax-friendliness for retirees, senior population and migration rates, and the strength of each city's job market.

Midland, Michigan was crowned the No. 1 best place to retire in 2026. The remaining cities that round out the top five are Weirton, West Virginia (No. 2) and Homosassa Springs, Florida (No. 3).

According to U.S. News, about 15 percent of The Woodlands' population is over the age of 65. The median household income in this suburb is $139,696, far above the national average median household income of $79,466.

Though The Woodlands has a higher cost of living than many other places in the country, the report maintains that the city "offers a higher value of living compared to similarly sized cities."

"If you want to buy a house in The Woodlands, the median home value is $474,279," the city's profile on U.S. News says. "And if you're a renter, you can expect the median rent here to be $1,449." For comparison, the report says the national average home value is $370,489.

Spring ranked as the fifth best place to retire in 2026, boasting a population of more than 68,000 residents, 11 percent of whom are seniors. This suburb is located less than 10 miles south of The Woodlands, while still being far enough away from Houston (about 25 miles) for seniors to escape big city life for the comfort of a smaller community.

"Retirees are prioritizing quality of life over affordability for the first time since the beginning of the COVID-19 pandemic," said U.S. News contributing editor Tim Smart in a press release.

The median home value in Spring is lower than the national average, at $251,247, making it one of the more affordable places to buy a home in the Houston area. Renters can expect to pay a median $1,326 in monthly rent, the report added.

Elsewhere in Houston, Pearland ranked as the 17th best place to retire for 2026, followed by Conroe (No. 20) and League City (No. 25).

Other Texas cities that ranked among the top 50 best places to retire nationwide include Victoria (No. 12), San Angelo (No. 28), and Flower Mound (No. 37).

The top 10 best U.S. cities to retire in 2026 are:

  • No. 1 – Midland, Michigan
  • No. 2 – Weirton, West Virginia
  • No. 3 – Homosassa Springs, Florida
  • No. 4 – The Woodlands, Texas
  • No. 5 – Spring, Texas
  • No. 6 – Rancho Rio, New Mexico
  • No. 7 – Spring Hill, Florida
  • No. 8 – Altoona, Pennsylvania
  • No. 9 – Palm Coast, Florida
  • No. 10 – Lynchburg, Virginia

Micro-nuclear reactor to launch at Texas A&M innovation campus in 2026

nuclear pilot

The Texas A&M University System and Last Energy plan to launch a micro-nuclear reactor pilot project next summer at the Texas A&M-RELLIS technology and innovation campus in Bryan.

Washington, D.C.-based Last Energy will build a 5-megawatt reactor that’s a scaled-down version of its 20-megawatt reactor. The micro-reactor initially will aim to demonstrate safety and stability, and test the ability to generate electricity for the grid.

The U.S. Department of Energy (DOE) fast-tracked the project under its New Reactor Pilot Program. The project will mark Last Energy’s first installation of a nuclear reactor in the U.S.

Private funds are paying for the project, which Robert Albritton, chairman of the Texas A&M system’s board of regents, said is “an example of what’s possible when we try to meet the needs of the state and tap into the latest technologies.”

Glenn Hegar, chancellor of the Texas A&M system, said the 5-megawatt reactor is the kind of project the system had in mind when it built the 2,400-acre Texas A&M-RELLIS campus.

The project is “bold, it’s forward-looking, and it brings together private innovation and public research to solve today’s energy challenges,” Hegar said.

As it gears up to build the reactor, Last Energy has secured a land lease at Texas A&M-RELLIS, obtained uranium fuel, and signed an agreement with DOE. Founder and CEO Bret Kugelmass said the project will usher in “the next atomic era.”

In February, John Sharp, chancellor of Texas A&M’s flagship campus, said the university had offered land at Texas A&M-RELLIS to four companies to build small modular nuclear reactors. Power generated by reactors at Texas A&M-RELLIS may someday be supplied to the Electric Reliability Council of Texas (ERCOT) grid.

Also in February, Last Energy announced plans to develop 30 micro-nuclear reactors at a 200-acre site about halfway between Lubbock and Fort Worth.

Houston falls from top 50 in global ranking of 'World's Best Cities'

Rankings & Reports

Houston is no longer one of the top 50 best cities in the world, according to a prestigious annual report by Canada-based real estate and tourism marketing firm Resonance Consultancy.

The newest "World's Best Cities" list dropped Houston from No. 40 last year to No. 58 for 2026.

The experts at Resonance Consultancy annually compare the world's top 100 cities with metropolitan populations of at least 1 million residents or more based on the relative qualities of livability, "lovability," and prosperity. The firm additionally collaborated with AI software company AlphaGeo to determine each city's "exposure to risk, adaptation capacity," and resilience to change.

The No. 1 best city in the world is London, with New York (No. 2), Paris (No. 3), Tokyo (No. 4), and Madrid (No. 5) rounding out the top five in 2026.

Houston at least didn't rank as poorly as it did in 2023, when the city surprisingly plummeted as the 66th best city in the world. In 2022, Houston ranked 42nd on the list.

Despite dropping 18 places, Resonance Consultancy maintains that Houston "keeps defying gravity" and is a "coveted hometown for the best and brightest on earth."

The report cited the Houston metro's ever-growing population, its relatively low median home values ($265,000 in 2024), and its expanding job market as top reasons for why the city shouldn't be overlooked.

"Chevron’s shift of its headquarters from California to Houston, backed by $100 million in renovations, crowns relocations drawn by record 2024 Port Houston throughput of more than four million containers and a projected 71,000 new jobs in 2025," the report said.

The report also draws attention to the city's diversity, spanning from the upcoming grand opening of the long-awaited Ismaili Center, to the transformation of several industrial buildings near Memorial City Mall into a mixed-use development called Greenside.

"West Houston’s Greenside will convert 35,000 square feet of warehouses into a retail, restaurant and community hub around a one-acre park by 2026, while America’s inaugural Ismaili Center remains on schedule for later this year," the report said. "The gathering place for the community and home for programs promoting understanding of Islam and the Ismaili community is another cultural jewel for the country’s most proudly diverse major city."

In Resonance Consultancy's separate list ranking "America's Best Cities," Houston fell out of the top 10 and currently ranks as the 13th best U.S. city.

Elsewhere in Texas, Austin and Dallas also saw major declines in their standings for 2026. Austin plummeted from No. 53 last year to No. 87 for 2026, and Dallas fell from No. 53 to No. 78.

"In this decade of rapid transformation, the world’s cities are confronting challenges head‑on, from climate resilience and aging infrastructure to equitable growth," the report said. "The pandemic, long forgotten but still a sage oracle, exposed foundational weaknesses – from health‑care capacity to housing affordability. Yet, true to their dynamic nature, the leading cities are not merely recovering, but setting the pace, defining new paradigms of innovation, sustainability and everyday livability."
