Houston innovators talked big topics at SXSW 2024 — from the startup scaling and converging industries to the future of work.

Houston House, which was put on by the Greater Houston Partnership on March 11, hosted four panels full of experts from Houston. If you missed the day-long activation, here are some highlights from the experts who each commented on the future of the Bayou City when it comes to startups, technology, innovation, and the next generation's workforce.

"When we think about Houston, we think about access to at-scale infrastructure, amenities, and workforce and talent pools."

— Remington Tonar, co-founder and chief growth officer at Cart.com, says about why the company chose to return its headquarters back to Houston last year. One of these amenities, Tonar explained, is Houston's global airports.

"If New York and Austin had a baby, it would be Houston, because you have friendly people with a big-city culture."

— Mitra Miller, vice president and board member of Houston Angel Network, says, adding that Houston has a cost efficiency to it, which should be at the forefront of founders' minds when considering where to locate.

"We are not only attracting global talents, we are also attracting global wealth and foreign investments because we are the rising city of the future. We are the global launch pad where you can scale internationally very quickly."

— Sunny Zhang, founder of TrueLeap, says adding how there's a redistribution of global workforce happening when you consider ongoing global affairs.

"We overwhelmingly as a company, and my co-founder would agree, knew we had to go the Houston path. And we started funneling a lot more resources here."

— Carolyn Rodz, co-founder and CEO of Hello Alice, says, explaining that the pandemic helped equalize the talent across the country, and this has been to the benefit of cities like Houston.

"Houston is here with arms open, welcoming people and actively recruiting."

— Sean Kelly, co-founder and CEO of Amperon, says, emphasizing how Texas has made moves to being business friendly. Amperon was founded in New York, before moving to Houston a couple years ago.

"There is a revolution starting to happen in Houston right now."

— Trevor Best, co-founder and CEO of Syzygy Plasmonics, says, first commenting on the momentum from Rice University, where his company's technology originates from. But, as he adds, when you compare the ecosystem when the startup was founded in 2019 to where it's at now, "there is so much more happening."

"Houston has a critical mass in terms of aerospace."

— Stephanie Munez Murphy of Aegus Aerospace says, saying specifically that NASA's Johnson Space Center holds some responsibility for that. "JSC is the home of opening up space commercialization."

"There's diversity in industries people are coming from, but also in terms of experience and expertise that (Houstonians) have."

— Robyn Cardwell of Omniscience says, adding that Houston's diversity goes further than just where people originate from. "Houston has all these pieces put together ... for growing and scaling organizations," she adds.

"I've worked with thousands of students in Houston who are actively looking to better themselves and grow their career post college or post high school and go into the workforce."

— Allie Danziger of Ascent Funding says, adding that Gen Z, which is already entering the workforce, is entrepreneurial and ready to change the world. "Seeing the energy of Houstonians is just thrilling," she adds.

"We're working together in the Houston community. ... There are so many opportunities to collaborate but we need conveners." 

— Stacy Putman of INEOS says, adding that within industry there has been a lack of discussion and collaboration because of competition. But, as she's observing, that's changing thanks to conveners at colleges or at the Greater Houston Partnership.

"The opportunity for Houston is that everybody has to step up to be in some way, shape, or form helping us with this."

— Raj Salhotra of Momentum Education says about supporting the future workforce of Houston, including low-income household students.

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 education to space tech — recently making headlines in Houston innovation.

For the second time in less than six years, Houston entrepreneur Allie Danziger has navigated a company through an exit. But, with the two exists under her belt, Danziger says the two transactions could not be any more different.

Danziger founded Integrate Agency, a digital-focused public relations firm, in 2009 and sold it to another marketing and PR firm based in Austin in 2018. She founded her next company, Ampersand Professionals, in 2020 to address the challenges for upskilling young professionals to prepare them for success in the workplace — something employers really wanted, but struggled to do consistently.

Last month, Ampersand was acquired by Ascent Funding, a college loan provider that's building out a platform to support its college-aged borrowers. In this week's episode of the Houston Innovators Podcast, Danziger shares how this opportunity came about and looks back on these two pivotal deals. Read more.

Rice University’s Office of Innovation has named Houston materials scientist-turned-entrepreneur Adrian Trömel as its new assistant vice president for strategy and investments.

Trömel founded non-invasive neurostimulation medical device company CNX Medical at the Texas Medical Innovation Institute in 2019 and most recently served as chief growth officer for Hamilton Health Box, which brings an on-site care team to company offices.

In his new role, Trömel will oversee the creation of the Rice Nexus, an innovation hub within the Ion that aims to bridge the gap between the university and Houston's innovation ecosystem. He will also lead the creation of a translational research grant fund and a university-affiliated venture fund for Rice-affiliated entrepreneurs. Read more.

Michael Suffredini, CEO and president of Axiom Space

Houston has another unicorn — a company valued at $1 billion or more — thanks to a recent round of funding.

Axiom Space released the news this week that it's closed its series C round of funding to the tune of $350 million. While the company didn't release its valuation, it confirmed to Bloomberg that it's over the $1 billion threshold. Axiom reports that, according to available data, it's now raised the second-most funding of any private space company in 2023 behind SpaceX.

Saudi Arabia-based Aljazira Capital and South Korea-based Boryung Co. led the round. To date, Axiom has raised over $505 million with $2.2 billion in customer contracts, according to the company.

“We are honored to team with investors like Aljazira Capital, Boryung and others, who are committed to realizing the Axiom Space vision,” Axiom Space CEO and president Michael Suffredini says in a news release. “Together, we are working to serve innovators in medicine, materials science, and on-orbit infrastructure who represent billions of dollars in demand over the coming decade.

How this Houston edtech startup's acquisition is primed to further advance platform reach, impact

HOUSTON INNOVATORS PODCAST EPISODE 200

For the second time in less than six years, Houston entrepreneur Allie Danziger has navigated a company through an exit. But, with the two exists under her belt, Danziger says the two transactions could not be any more different.

Danziger founded Integrate Agency, a digital-focused public relations firm, in 2009 and sold it to another marketing and PR firm based in Austin in 2018. She founded her next company, Ampersand Professionals, in 2020 to address the challenges for upskilling young professionals to prepare them for success in the workplace — something employers really wanted, but struggled to do consistently.

Last month, Ampersand was acquired by Ascent Funding, a college loan provider that's building out a platform to support its college-aged borrowers. In this week's episode of the Houston Innovators Podcast, Danziger shares how this opportunity came about and looks back on these two pivotal deals.

"Integrate definitely was not built to sell — I didn't even know that people sold businesses when I was 24 (and started the agency," Danziger, who worked in PR her entire career at that time, says, adding that she thought she'd work at the company her whole life before passing it down to her children. "It ended up being a life-changing experience and opportunity because it did open my eyes up to other other things that I could do professionally — and also just kind of like the way that businesses are structured and run."

One of those things she considered post acquisition was upskilling entry-level employees. At Integrate, she hired a lot of interns and recent college graduates. She recognized there was a gap in the market. The first problem she identified was the need to match interns to positions at companies in an optimized way. While that's how the company started, it pivoted as Danziger says she saw the bigger need not for finding interns, but for making sure they were ready for their positions from the start.

"Most business leaders need their interns and entry-level employees starting day one with an understanding of how to communicate, and they don't really have the resources to teach them some of these skills," she explains.

Once the Ampersand platform, which has tons of resources and hours of instruction loaded on it, the challenge was finding the stakeholders that wanted the platform to exist — her potential customers. Was it the colleges or the employers? Through this journey, she realized that college loan lenders are part of that equation too.

"The lenders — the ones who are giving the student loans — they're the ones who really need them to be successful in the workplace," Danziger explains, saying the success of their loan recipients ensures a timely payout for the lender. "Their business model is predicated on students being successful, and I'd always known that, but not quite known what to do with that knowledge."

Danziger says the idea for acquisition, while always in the back of her mind, really became a possibility when she went out to raise funding.

"You're always raising money, and you're always for sale," Danziger says of the startup journey.

When a potential investor raised the idea of being a potential acquirer, Danziger says she started doing some soul searching. The right acquisition deal could help her address the milestones she wanted to reach with investment funding — growing her team, expanding her technology, and broadening reach. Through a diligent process, Danziger decided on Ascent from a few other potential acquirers.

"I'm not going anywhere. I want to still keep solving this problem, but with a larger team and larger resources," she says. "Either I could go find that myself, or I could join forces we could join forces with an established organization."

Danziger says her role at Ascent is still being constructed in terms of scope and responsibilities, but her title as of now is senior vice president and general manager of student success. She will lead the company's educational program that focuses on equipping students with skills from education to employment.

She shares more on the acquisition process — including her advice to startups thinking about the M&A path. Listen to the interview here — or wherever you stream your podcasts — and subscribe for weekly episodes.

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.
