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.

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow. The collaborative community offers members state-of-the-art prototyping labs, business resources and access to investors and corporate partners. The co-located incubator was first launched in Boston in 2011 before opening in Houston in 2021.

Greentown has seen major changes and activity this year. In February, Greentown announced Georgina Campbell Flatter as its new CEO, along with a new Board of Directors. In July, it announced Lawson Gow as its Head of Houston, a "dedicated role to champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region," according to Greentown. It has since announced numerous new partnerships, including those with Energy Tech Nexus, Los Angeles-based software development firm Nominal, to launch the new Industrial Center of Excellence; and Houston-based Shoreless, to launch an AI lab onsite. Greentown Houston has supported 175 startups since its launch in 2021, with 45 joining in the last two years. Those startups include the likes of Hertha Metals, RepAir Carbon, Solidec, Eclipse Energy (formerly GoldH2) and many others.

Healthtech Accelerator (TMCi)

The Healthtech Accelerator, formerly TMCx, focuses on clinical partnerships to improve healthcare delivery and outcomes. Emerging digital health and medical device startups that join the accelerator are connected with a network of TMC hospitals and seasoned advisors that will prepare them for clinical validation, funding and deployment.

The Healthtech Accelerator is part of Texas Medical Center Innovation, which also offers the TMCi Accelerator for Cancer Therapeutics. The Healthtech Accelerator named its 19th, and latest, cohort of 11 companies last month.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

Rice University launches  engineering-led brain science and health institute

brain research

Rice University has announced the creation of a new interdisciplinary center known as the Rice Brain Institute (RBI).

The new hub will aim to use engineering, natural sciences and social sciences to research the brain and reduce the burden of neurodegenerative, neurodevelopmental and mental health disorders.

“The Rice Brain Institute reflects Rice’s strength in collaboration without boundaries,” Rachel Kimbro, dean of the School of Social Sciences, said in a news release. “Our researchers are not only advancing fundamental science but they’re also ensuring that knowledge reaches society in ways that promote human flourishing.”

RBI researchers will work in thematic clusters focusing on neurodegeneration, mental health, brain injury and neurodevelopment. The clusters will work toward goals such as significantly improving key brain health outcomes, reducing mortality and mental health disorders and improving quality of life for patients living with brain injuries and neurodevelopmental disorders, according to Rice.

The institute will focus on “engineering-driven innovation,” rather than traditional neuroscience, to design tools that can measure, model and modulate brain activity based around Rice’s expertise in soft robotics, neuroimaging, data science and artificial intelligence—making it unique among peer organizations, according to Rice.

Additionally, RBI will be structured around three collaborative Rice “pillars”:

  • The Neuroengineering Initiative, launched in 2018, brings together neuroscience, engineering, and related fields experts
  • The Neuroscience Initiative, a new initiative that brings together cell biologists, neurobiologists, biochemists, chemists and physicists to explore fundamental mechanisms of the brain and nervous system
  • The Brain and Society Initiative, also a new initiative, considers brain research within the broader social and policy landscape

Rice’s Neuroengineering Initiative has already garnered more than $78 million in research funding, according to Rice, and has established major partnerships, like the Rice-Houston Methodist Center for Neural Systems Restoration.

“Rice is uniquely equipped to bridge and connect scientific understanding of the brain and behavior sciences with the technologies and policies that shape our world,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, added in the news release. “By uniting faculty in neuroengineering, neuroscience and psychological sciences, this interdisciplinary hub embodies the kind of bold, nimble collaboration that allows Rice to turn discovery into societal impact to save lives and enhance human flourishing.”

The formation of the RBI coincides with recent support of the Dementia Prevention Research Institute of Texas (DPRIT), which landed voter approval earlier this week and aims to make Texas the center for dementia research via brain-health tech. According to the World Economic Forum, brain disorders and mental health disorders cost the global economy an estimated $5 trillion per year and could be as high as $16 trillion by 2030.

“Few areas of research have as direct and profound an impact on human well-being as brain health,” Rice President Reginald DesRoches added in the news release. “As rates of Alzheimer’s, dementia and other neurological diseases rise in our country and around the world, universities have a responsibility to lead the discovery of solutions that preserve memory, movement and quality of life. We all know someone who has been affected by a brain-related health issue, so this research is personal to all of us.”

Texas voters OK $3 billion for new dementia research institute

state funding

Texas voters on Nov. 4 overwhelmingly approved a ballot measure that provides $3 billion in state funding over a 10-year span for the newly established Dementia Prevention and Research Institute of Texas (DPRIT).

Thanks to the passage of Proposition 14, Texas now boasts the country’s largest state-funded initiative dedicated to dementia research and prevention, according to the Alzheimer’s Association. Up to $300 million in grants will be awarded during the 10-year funding period.

“This is a transformative moment for Texas and for the fight against Alzheimer’s and all other dementia,” said Joanne Pike, president and CEO of the Alzheimer’s Association. “Texans have chosen to invest in hope, innovation, and solutions for the millions of families affected by these devastating diseases. With the passage of Proposition 14, Texas is now poised to lead the nation in dementia research and prevention.”

The association says DPRIT will drive scientific breakthroughs, attract top-notch dementia researchers to Texas, and generate thousands of jobs statewide.

An estimated 460,000 Texans are living with dementia, the association says, and more than one million caregivers support them.

DPRIT is modeled after the Cancer Prevention and Research Institute of Texas (CPRIT). Since 2008, the state agency has awarded nearly $4 billion in grants to research organizations for cancer-related academic research, prevention programs, and product development.

An analysis by the McKinsey Health Institute found that investing in brain health initiatives like DPRIT could boost Texas’ GDP by $260 billion. Much of that GDP bump could benefit the Houston area, which is home to dementia-focused organizations such as UTHealth Houston Neurosciences, Baylor College of Medicine’s Center for Alzheimer’s and Neurodegenerative Diseases, the University of Texas Medical Branch at Galveston’s Collaborative Alzheimer’s Disease and Memory Disorders Program, and the Houston Methodist Research Institute’s John M. O’Quinn Foundation Neurodegenerative Disorders Laboratory.

The Greater Houston Partnership says DPRIT holds the potential “to elevate Texas — particularly Houston — as a hub for brain health research.”

State Sen. Joan Huffman, a Houston Republican, is one of DPRIT’s champions. She sponsored legislation this year to create the institute and ask Texas voters to approve the $3 billion in funding.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said in May. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our health care community.”
