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.

Tech giant Apple doubles down on Houston with new production facility

coming soon

Tech giant Apple announced that it will double the size of its Houston manufacturing footprint as it brings production of its Mac mini to the U.S. for the first time.

The company plans to begin production of its compact desktop computer at a new factory at Apple’s Houston manufacturing site later this year. The move is expected to create thousands of jobs in the Houston area, according to Apple.

Last year, the Cupertino, California-based company announced it would open a 250,000-square-foot factory to produce servers for its data centers in the Houston area. The facility was originally slated to open in 2026, but Apple reports it began production ahead of schedule in 2025.

The addition of the Mac mini operations at the site will bring the footprint to about 500,000 square feet, the Houston Chronicle reports. The New York Times previously reported that Taiwanese electronics manufacturer Foxconn would be involved in the Houston factory.

Apple also announced plans to open a 20,000-square-foot Advanced Manufacturing Center in Houston later this year. The project is currently under construction and will "provide hands-on training in advanced manufacturing techniques to students, supplier employees, and American businesses of all sizes," according to the announcement. Apple opened a similar Apple Manufacturing Academy in Detroit last year.

“Apple is deeply committed to the future of American manufacturing, and we’re proud to significantly expand our footprint in Houston with the production of Mac mini starting later this year,” Tim Cook, Apple’s CEO, said in the news release. “We began shipping advanced AI servers from Houston ahead of schedule, and we’re excited to accelerate that work even further.”

Apple's Houston expansion is part of a $600 billion commitment the company made to the U.S. in 2025.

Houston energy trailblazer Fervo taps into hottest reservoir to date

Heating Up

Things are heating up at Houston-based geothermal power company Fervo Energy.

Fervo recently drilled its hottest well so far at a new geothermal site in western Utah. Fewer than 11 days of drilling more than 11,000 feet deep at Project Blanford showed temperatures above 555 degrees Fahrenheit, which exceeds requirements for commercial viability. Fervo used proprietary AI-driven analytics for the test.

Hotter geothermal reservoirs produce more energy and improve what’s known as energy conversion efficiency, which is the ratio of useful energy output to total energy input.

“Fervo’s exploration strategy has always been underpinned by the seamless integration of cutting-edge data acquisition and advanced analytics,” Jack Norbeck, Fervo’s co-founder and chief technology officer, said in a news release. “This latest ultra-high temperature discovery highlights our team’s ability to detect and develop EGS sweet spots using AI-enhanced geophysical techniques.”

Fervo says an independent review confirms the site’s multigigawatt potential.

The company has increasingly tapped into hotter and hotter geothermal reservoirs, going from 365 degrees at Project Red to 400 degrees at Cape Station and now more than 555 degrees at Blanford.

The new site expands Fervo’s geologic footprint. The Blanford reservoir consists of sedimentary formations such as sandstones, claystones and carbonates, which can be drilled more easily and cost-effectively than more commonly targeted granite formations.

Fervo ranks among the top-funded startups in the Houston area. Since its founding in 2017, the company has raised about $1.5 billion. In January, Fervo filed for an IPO that would value the company at $2 billion to $3 billion, according to
