Six Houston-area sustainability startups have been named finalists in the 2023 Houston Innovation Awards, but they didn't achieve this recognition — as well as see success for their businesses — without any obstacles.

The finalists were asked what their biggest challenges have been. From funding to market adoption, the sustainability companies have had to overcome major obstacles to continue to develop their businesses.

The awards program — hosted by InnovationMap, and Houston Exponential — will name its winners on November 8 at the Houston Innovation Awards. The program was established to honor the best and brightest companies and individuals from the city's innovation community. Eighteen energy startups were named as finalists across all categories, but the following responses come from the finalists in the sustainability category specifically.

    1. Securing a commercial pilot

    "As an early-stage clean energy developer, we struggled to convince key suppliers to work on our commercial pilot project. Suppliers were skeptical of our unproven technology and, given limited inventory from COVID, preferred to prioritize larger clients. We overcame this challenge by bringing on our top suppliers as strategic investors. With a long-term equity stake in Fervo, leading oilfield services companies were willing to provide Fervo with needed drilling rigs, frack crews, pumps, and other equipment." — Tim Latimer, founder and CEO of Fervo Energy

    2. Finding funding

    "Securing funding in Houston as a solo cleantech startup founder and an immigrant with no network. Overcome that by adopting a milestone-based fundraising approach and establishing credibility through accelerator/incubator programs." — Anas Al Kassas, CEO and founder of INOVUES

    "The biggest challenge has been finding funding. Most investors are looking towards software development companies as the capital costs are low in case of a risk. Geothermal costs are high, but it is physical technology that needs to be implemented to safety transition the energy grid to reliable, green power." — Cindy Taff, CEO of Sage Geosystems

    3. Market adoption

    "Market adoption by convincing partners and government about WHP as a solution, which is resource-intensive. Making strides by finding the correct contacts to educate." — Janice Tran, CEO and co-founder of Kanin Energy

    "We are creating a brand new financial instrument at the intersection of carbon markets and power markets, both of which are complicated and esoteric. Our biggest challenge has been the cold-start problem associated with launching a new product that has effectively no adoption. We tackled this problem by leading the Energy Storage Solutions Consortium (a group of corporates and battery developers looking for sustainability solutions in the power space), which has opened up access to customers on both sides of our marketplace. We have also leveraged our deep networks within corporate power procurement and energy storage development to talk to key decision-makers at innovative companies with aggressive climate goals to become early adopters of our products and services." — Emma Konet, CTO and co-founder of Tierra Climate

    4. Long scale timelines

    "Scaling and commercializing industrial technologies takes time. We realized this early on and designed the eXERO technology to be scalable from the onset. We developed the technology at the nexus of traditional electrolysis and conventional gas processing, taking the best of both worlds while avoiding their main pitfalls." — Claus Nussgruber, CEO of Utility Global

    An architect by trade, Anas Al Kassas says he was used to solving problems in his line of work. Each project architects take on requires building designers to be innovative and creative. A few years ago, Kassas took his problem-solving background into the entrepreneurship world to scale a process that allows for retrofitting window facades for energy efficiency.

    “If you look at buildings today, they are the largest energy-consuming sector — more than industrial and more than transportation,” Kassas, founder and CEO of INOVUES, says on the Houston Innovators Podcast. “They account for up to 40 percent of energy consumption and carbon emissions.”

    To meet their climate goals, companies within the built environment are making moves to transition to electric systems. This has to be done with energy efficiency in mind, otherwise it will result in grid instability.

    "Energy efficiency goes hand in hand with energy transition," he explains. Read more.

    With the holidays in full swing, and small businesses looking to gain back revenues lost during the COVID-19 pandemic, Walmart and Houston-based Popable are providing the opportunity to display and sell their products at Walmart can be highly beneficial to recoup profits, and unload new and extra products to a larger audience.

    “Going into the holidays the timing is pretty good for a lot of brands looking to move some access inventory that they have loaded up from last year, but this (hopefully with Walmart) will be a year-round thing,” says Popable CEO and co-founder Scott Blair. “The pop-up opportunities we’ve been seeing with brands doing reach outs so far, a lot of them are looking for stuff into January and February too.”

    Popable has assisted brands secure qualified spaces, get education and resources, and build community, and connections that are vital to helping small businesses expand their visibility in the marketplace. The platform simultaneously helps retail landlords find qualified retailers from a directory of tens of thousands of brands to fill vacancies and drive traffic to their shopping centers. Read more.

    HOUSTON INNOVATORS PODCAST EPISODE 163

    An architect by trade, Anas Al Kassas says he was used to solving problems in his line of work. Each project architects take on requires building designers to be innovative and creative. A few years ago, Kassas took his problem-solving background into the entrepreneurship world to scale a process that allows for retrofitting window facades for energy efficiency.

    “If you look at buildings today, they are the largest energy-consuming sector — more than industrial and more than transportation,” Kassas, founder and CEO of INOVUES, says on the Houston Innovators Podcast. “They account for up to 40 percent of energy consumption and carbon emissions.”

    To meet their climate goals, companies within the built environment are making moves to transition to electric systems. This has to be done with energy efficiency in mind, otherwise it will result in grid instability.

    "Energy efficiency goes hand in hand with energy transition," he explains.

    Kassas says that he first had the idea for his company when he was living in Boston. He chose to start the business in Houston, attracted to the city by its central location, affordable labor market, and manufacturing opportunities here.

    Last year, INOVUES raised its first round of funding — a $2.75 million seed round — to scale up the team and identify the best markets to target customers. Kassas says he was looking for regions with rising energy rates and sizable incentives for companies making energy efficient changes.

    "We were able to now implement our technology in over 4 million square feet of building space — from Boston, Seattle, Los Angeles, New York City, Portland, and very soon in Canada," he says.

    Notably missing from that list is any Texas cities. Kassas says that he believes Houston is a great city for startups and he has his operations and manufacturing is based here, but he's not yet seen the right opportunity and adaption

    "Unfortunately most of our customers are not in Texas," he says. "A lot of work can be done here to incentivize building owners. There are a lot of existing buildings and construction happening here, but there has to be more incentives."

    Kassas shares more about his growth over the past year, as well as what he has planned for 2023 on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

    Houston startup raises $2.75M to make buildings more energy efficient

    seeing green

    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."

    Houston leads U.S. with the biggest surge in millionaire renters

    Rent Report

    The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

    Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

    "The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

    Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

    Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

    But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

    Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

    This is who the typical millionaire renter is
    The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

    "Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

    The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

    The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

    "These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

    Hotspots for millionaire homeowners
    In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

    Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

    Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

    Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

    Houston ranks high on best cities for small-business expansion report

    business growth

    For small businesses looking to expand, Houston might be the right place.

    Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

    A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

    “Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

    Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

    Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

    “The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

    The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

    “For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

    “Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

    Of course, money fuels small-business expansion in the Houston area or anywhere else.

    According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

    Altogether, the 7(a) and 505 loans exceeded $1 billion.

    The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

    Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.

    What to expect from the inaugural TiECon Texas event this week

    where to be

    Innovators and entrepreneurs will gather in Houston this week to show off their latest advancements in automation during the first-ever TiECon Texas conference at the Ion District.

    “Automation is not simply changing how we work. It is redefining how value is created across every industry,” Somesh Singh, president of TiE Houston, said in a release. “Texas has the talent, the infrastructure, and the entrepreneurial spirit to lead this transformation. TiEcon Texas 2026 is where the people building that future will come together to shape it."

    The Indus Entrepreneurs (TiE) started in Silicon Valley in 1994 as a two-day seminar, but has grown into a worldwide network of events celebrating technological advancement. TiECon in Houston is a merger of the TiE networks across Texas for one large-scale event taking place at the Ion on Wednesday, October 28, and Thursday, October 29. Tickets are available here.

    The event includes a partnership with Hatch Pitch, a founder-first startup showcase that has raised over $20 billion in funding for new companies in the tech industry. Participants will come from industries like space exploration, healthcare, energy, and the AI sector to present their ideas in front of an investor network for possible development.

    “Over 80 percent of the teams we have coached have gone on to receive funding,” Greg Wright, founder of Hatch Pitch, added in a release.

    In addition, there will be forums and talks on a variety of automation subjects, everything from robotic surgery to automation in government. Educators from Baylor College of Medicine, UTHealth Houston, and the University of Houston plan to discuss the raising of children in a world with extensive artificial intelligence integrated into so many areas. Steven Kean, President and CEO of the Greater Houston Partnership, will give the keynote speech on the Bayou City’s place in these emerging technological spheres.

    Singh highlighted how the large-scale disruptions in the technological status quo by the rise of AI could be a sign of potential growth and innovation. The entrepreneurs presenting at TiECon may be the ones to harness the sometimes unsteady AI industry for good causes.

    “History shows that periods of technological disruption create extraordinary opportunities for those prepared to act,” he said. “TiEcon Texas is designed to help founders, investors, and enterprises understand where the automation economy is headed and how to participate in building it."

    Here are the 10 startups pitching during the TiE Hatch Pitch competition:
