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.

UTHealth Houston officially opens new tower in TMC's Helix Park

open for innovation

UTHealth Houston School of Public Health recently opened its new state-of-the-art tower in the Texas Medical Center’s Helix Park.

The 350,000-square-foot, 10-story campus at 1930 Old Spanish Trail was celebrated with an official ribbon-cutting ceremony on Oct. 28. The $229 million project will consolidate all UTHealth Houston School of Public Health operations into one facility. It will also connect students who are at the Austin, Brownsville, Dallas, El Paso and San Antonio campuses with peers and faculty through digital and distance learning.

Disciplines taught in the new tower will include epidemiology, genetics, nutrition, health policy, data science and health promotion, UTHealth shared when the building first broke ground in 2023.

Architects Kirksey Architecture and Smith Group designed the building, and Vaughn Construction served as general contractor. The facility features labs for studying human disease, classrooms and spaces to support interdisciplinary and community-based research, a broadcast studio and a teaching kitchen. A skybridge over Old Spanish Trail connects the new tower with a plaza that's shared with MD Anderson.

“This new facility reflects the kind of forward-looking investment that will serve Texans for generations,” Janiece Longoria, vice chairman of the UT System Board of Regents, said in a news release. “By creating an environment where talented people can learn, collaborate, and pursue new ideas, UTHealth Houston is building capacity to meet the challenges of tomorrow while strengthening its impact across our state.”

UTHealth says the system aims for the new campus to expand on collaborative research efforts and continue graduate education, as enrollment at the School of Public Health has increased by 27 percent over the last five years.

“This new building, with its state-of-the-art education technology and learning environment, will strengthen and advance the school’s mission to educate and train the next generation of experts who will advance scientific discovery, shape evidence-based health policy, and lead innovative solutions to the complex health challenges in communities throughout Texas and across the nation,” Kevin Morano, senior vice president, provost and chief academic officer of UTHealth Houston, added in a news release.

Attending the ceremony were Dr. Melina R. Kibbe, UTHealth Houston president and Alkek Williams Distinguished Chair; Eric Boerwinkle, dean, M. David Low Chair in Public Health and Kozmetsky Family Chair in Human Genetics at the School of Public Health; Texas State Representative Lauren Ashley Simmons, Texas House District 146; representatives of the offices of Senator John Cornyn and Harris County Commissioner Rodney Ellis; and Dr. Theresa Tran, director of the Houston Health Department.

"This building represents far more than a home for our school,” Boerwinkle added in the release. “It represents the people who make our mission possible: the faculty, staff, and students who fill each laboratory and classroom with curiosity, discovery, and purpose to improve the population’s quality of life.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.
