A Houston startup is celebrating its nationwide launch of its flagship product that coats roofs to reduce energy waste.

NanoTech's Nano Shield Cool Roof Coat is a unique product that can be added onto roofs to reduce energy waste on buildings. Co-founder and CEO Mike Francis and Chief Commercial Officer Carrie Horazeck joined the Houston Innovators Podcast to share more details about the product.

"It's just a coating that can go on top of existing structure — any type of commercial roof," Horazeck says on the show. "We have a pretty good amount of data from 2022 showcasing that we can reduce HVAC consumption within the building by about 30 to 40 percent.

"Our clients really see a immediate benefit in their energy bill, and, of course, if you reduce the HVAC consumption, that automatically translates to a decrease in your scope one emissions," she continues. Continue reading.


Episode 181 - Gearing up for high-speed global travel - Sassie Duggleby of Venus Aerospace

Sarah "Sassie" Duggleby is on a mission to get people home in time for dinner — whether they are traveling around the world or working for her business. That's why she founded Venus Aerospace, which is developing hypersonic space planes. It's also why she relocated the company from the West Coast to Houston.

"We knew we had to find a location where we could test our engine and still be home for dinner," Duggleby says on this week's episode of the Houston Innovators Podcast. "Our company vision is 'home for dinner.' We want to fly you across the globe and have you home for dinner. And, if you work for us, we want you home for dinner."

Venus's technology enables this revolutionary travel through its supersonic combustion engine — more akin to a rocket's engine than an airplane's — that allows for travel at a higher elevation, she explains on the show. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally. And, as Duggleby explains, the engine can go further with the same amount of fuel, so it's a more sustainable way of traveling too. Continue reading.


Episode 182 - Stopping neurodegenerative diseases in their tracks - Howard Berman of Coya Therapeutics

When Howard Berman sought out renowned Houston Methodist researcher and neurologist Dr. Stanley Appel, he was looking for treatment for his father, who was suffering from dementia. He wasn't looking for a job, but Dr. Appel had other ideas and asked Berman to meet with him.

"I was interested in what I could do for my dad," Berman says on the Houston Innovators Podcast, explaining how he took the meeting with Dr. Appel, who then presented him with some of his research. "By slide five my jaw had hit the ground.

"He had shown that he could stop the progression in one of his early trials of ALS," Berman says.

Not too long after that meeting, Berman, who founded digital health platform imaware, joined Dr. Appel to lead commercialization of Coya Therapeutics, a biotech startup that raised over $20 million in venture funding before going public a few months ago. Continue reading.


Episode 187 - Bridging the gap to innovation - Ramanan Krishnamoorti of University of Houston

Ramanan Krishnamoorti has had a varied career in academia, from an engineering professor to nanotech research. While he never made the transition from researcher to entrepreneur, he managed to snag a CEO title at the university about a decade ago: Chief energy officer.

Since then his role has expanded to include advancing UH's innovation of all kinds — from health tech to the arts — as vice president of energy and innovation at UH. In his role, he oversees the UH Technology Bridge, a lab and coworking space for tenants just a short drive away from UH's main campus, as well as future plans, like a new central campus hub for innovation that's in its early stages of development.

"What we really need at the university today is to bring innovation — which tech transfer is a piece of — and connect that to real-world challenges to deliver what the world needs, which is talented folks delivering new innovative, entrepreneurial, or intrapreneurial programs," Krishnamoorti says on this week's episode of the Houston Innovators Podcast.

Episode 193 - Innovating in the East End - Erik Ibarra of Magnolia Fund and ORDRS

Innovation isn't always tinkering with tech or programming software, although serial entrepreneur Erik Ibarra knows that world well. Sometimes it's about rethinking how a community improves and develops without doing the residents a disservice.

That's why Ibarra started Magnolia Fund, a mission-driven investment fund dedicated to enriching the East End community and preserving the neighborhood's culture and history. Ibarra, who has lived in the area the majority of his life, says on the Houston Innovators Podcast, that he's looking to turn residents into investors.

"Our investors from the neighborhood, today they walk around and look at their house and say, 'I own that,' and that's great," Ibarra says. "In the future, our investors should be able to say that, and then point to a building and say, 'I own a portion of that building too. And I helped that small business over there.'"

Anshumali Shrivastava's career has evolved alongside the rise of artificial intelligence. Now, he believes his company represents the future of the industry's widespread implementation.

Shrivastava, who's also a professor at Rice University, founded ThirdAI, pronounced "third eye," in 2021 to democratize artificial intelligence through software innovations. As Shrivastava explains on the Houston Innovators Podcast, AI processes have historically been run on larger, less accessible computing hardware. ThirdAI's tools are able to run on a regular central processing unit, or CPU, rather than the more powerful graphics processing unit, or GPU.

"We focus on the problems that people are facing in the current AI ecosystem," Shrivastava says on the podcast. "Right now, if you are to build some of the large-language models and (linear programming) models, you need a lot of computing power, dedicated engineers to move it, and, even if you are using fully managed services, it's costly and there are a lot of privacy implications because you have to move data around."

For years, Hello Alice has been helping small businesses across the country get equitable access to funding and support. Now, the Houston tech company is facing its own obstacle: An affirmative action lawsuit.

"I don't think in a million years that we ever expected anything like this," Elizabeth Gore, co-founder and president of Hello Alice, says on the Houston Innovators Podcast. "There's surprise, then there's fear, and then there's anger. But now on the other side of it, we're emboldened, confident, and more passionate than ever."

America First Legal's lawsuit against Hello Alice and its partner, Progressive Insurance, alleges that their program to award10 $25,000 grants to Black-owned small businesses constitutes racial discrimination. AFL was founded by former Trump Administration adviser Stephen Miller and features a handful of other former White House officials on its board. Continue reading.

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
