3 observations about Houston's innovation ecosystem from out-of-town venture capitalists

Zooming out

You'll go cross-eyed looking at the same puzzle for too long, and sometimes it's better to take a step back and introduce some fresh perspectives and ideas from someone not so connected to the matter at hand.

At the second annual HX Capital Summit hosted by Houston Exponential at Rice University, HX gathered three out-of-town venture capital experts to discuss Houston's innovation ecosystem with Sandy Wallis, managing director at the HX Venture Fund. The fund-of-funds focuses on connecting non-local investors to Houston in order to bring new venture opportunities to town. On the panel, the experts discussed their observations about the Bayou City, which can be summed up as follows.

Community engagement and corporate interest are good signs for Houston 

Right off the bat, the panelists agreed that its much more encouraging visiting Houston nowadays than it was in the recent past. Clint Korver, managing director at San Francisco-based Ulu Ventures, has only recently played witness to the city, thanks to his firm's work with HX and the fund of funds.

"I'm just getting to know the Houston community," Korver says. "I'm really intrigued by how much community support there is."

Korver says that, not unlike Houston startups, Bay Area companies find it a challenge getting a foot in the door at major corporations. However, he's observed that Houston-based corporates want a seat at the table of Houston innovation.

"All the corporate attention that's being integrated here is super intriguing," Korver says. "That's our startups' hardest problems."

The other panelists, who are much closer to Houston, echoed Kover's interest in the role corporations play. Venu Shamapant, founding partner at Austin-based LiveOak Venture Partners, and Thomas Ball, founder and managing director at Austin-based Next Coast Ventures, have witnessed Houston evolve into what it is today over the past decade or so.

"We've both been coming to Houston over the past 20 years and been investing in startups, and it's been a dramatically different scene even in just the past five years," Shamapant says.

Houston's ecosystem is going to take time

While the panelists remarked on the evolution the city has and the support that large corporations seem to be willing to provide, Houston has other assets that's setting it up for success. The panelists mention a solid pool for talent, impressive educational institutions, and more.

"When I look at Houston, I think it has every ingredient for success, which is why I want to spend time here," Ball says.

Sure, as Ball says, Houston has the ingredients, but what it now needs is the time to cook.

"To me, it's more of just time that it's going to take. We can't bake this Houston cake by turning the thermostat up to 900 degrees in an hour. It's going to take three hours at 300," Ball says, adding that he doesn't know very much about baking. "It will take time. This won't be an overnight success. We're here for the long haul."

Houston has some challenges yet to overcome 

Wrapping up the panel, an audience member asked about the changes Houston still needs to make to really get to the point it needs to be at.

For Korver, the answer was pretty simple. Houston needs a big exit.

"There's this incredible amount of momentum that comes along with a successful company that takes a hold of everyone — the rising tide floats all boats thing," Korver says.

For Ball, particularly comparing Houston to other major innovation-focused cities, the issue is that Houston is so spread out.

"To me the one thing I struggle with in Houston is what I would call a density problem," Ball says. "I think you need density here and you need to concentrate your resources in certain places in this city."

Here’s how big companies are looking to invest in Houston startups

B2B

As times and technologies change, large companies need to be able to adopt innovative techniques now more than ever. For some companies, that means making a strategic hire, investing in startups, or making acquisitions.

Three panelists with experience in corporate ventures took the stage at the inaugural HX Capital Summit to discuss their best advice for startups looking for investment from large companies.

The panel consisted of Roy Johnston, partner at The League of Worthwhile Ventures; Tom Luby, head of Jlabs; Andrea Course, venture principal at Schlumberger Technical Investments; and moderator Rashad Kurbanov, CEO of Houston-based iownit capital and markets.

The topic of conversation was how corporations work with startups. For Schlumberger, Course says, it's less about acquiring companies and more about investing in technologies those startups are working on.

"When Schlumberger does invest, we like to have a pilot and invest in properties we can grow," Course says. "Our intent is not to go out and buy a startup company, but to grow the technology and then become customers."

Schlumberger has a lot to offer a budding company, namely resources, infrastructure, assets, and a global footprint, Course says.

Previous to his position at The League, Johnston was the director in the venture capital arm of Waste Management, Inc. He says he saw a similar resources-based investment strategy.

"Waste Management might have been more hesitant to write a check, but they were very generous with their assets," Johnston says.

The company could make connections for the startups and provide other support for entrepreneurs in the early stages of starting a company. However, when it came to monetary investments, Johnston says, it was a different story.

"Where I think Waste Management comes in is later on — more of an acquirer than an investor," Johnston says.

When it comes to the types of startups big companies are looking to work with, industry isn't a big issue. Johnson & Johnson, for instance, has an open mind, Luby says.

"It's not an easy fit to say a specific area where J&J fits — if you look at the profile of things we do, we have a no-strings-attached incubation hub next door," he says.

Schlumberger similarly looks outward to spark innovation inward — mostly, Course says, because it's so challenging to think outside the box when you're working everyday inside the box.

"We mostly invest in companies outside of oil and gas, but that we see the potential of bringing used in our industry," Course says.

Houston, has a surplus of diversity — both industry and population, Johnston says. This will be a huge asset of the city, he says, since Houston is on the edge of another revolution for digitization.

"The businesses that are going to be built are going to need people who have a diverse understanding of problems," Johnston says. "That's where I think Houston's diversity is an enormous benefit to us."

Leading venture capitalists forecast the future of funding in Houston

Follow the money

Despite Houston being known for its money, venture capital has struggled to hit its stride until recently. Now, as Houston has attracted more money for its startups — even coming close to Austin, according to recent data — the Bayou City faces a challenge ahead.

"We will go through a massive tech correction — period. End of story," says Blair Garrou, managing partner of Houston-based Mercury Fund, at the inaugural HX Capital Summit.

The correction, Garrou says, would have happened a few years ago, but Middle Eastern and Chinese investments have been holding down the fort, so to speak.

"Whenever this correction happens, whether it's a year, two years, or three years, [my hope is] that the capital here invests through the cycle," Garrou says. "Anyone who invests through the cycle will win."

Garrou was joined by a few other venture capitalists on the panel hosted by Houston Exponential at the TMC Innovation Institute on December 4: Tim Kopra, partner at Houston-based Blue Bear Capital; Mark Friday, associate at Houston-based Cathexis; Joe Milam, CEO of Austin-based Angelspan; Jay Zeidman, managing partner of Houston-based Altitude Ventures Texas; and moderator Rashad Kurbanov, CEO of Houston-based iownit capital and markets.

While the tech correction looms, Houston's current venture ecosystem blooms, thanks to a rise in high net worth personal and family investments.

"There's a real hunger from a lot of ultra-high net worth families to get into this sector, and it'd be really interesting if we can cultivate that here in Houston," says Kopra.

People have gotten more comfortable investing in tech, says Garrou, so the investment opportunities have grown.

"There's a greed component to it that people don't like to talk about," Garrou says. "When people see people making money in a certain sector, they say, 'why not me.'"

However, there are a few things holding back some investors. One being that companies from earlier venture funds have yet to reach their full potential, says Garrou, and he and other venture capitals need to move the needle on that to demonstrate success. He says, once that happens, more capital will flow.

Another hesitation Zeidman says he's seen is within investing in funds, rather than directly into startups.

"There's a difference in investing in companies and investing in funds," Zeidman. "I think a lot of folks are skeptical about investing in funds. I want to be in a deal — I don't just want to give you money and you go decide what to do with it."

Houston Exponential, the city-backed innovation arm for Houston, launched a fund of funds in October. The HX Venture Fund has the potential to create a "flywheel effect" in Houston, says Garrou.

"We're going to see dozens and dozens of funds from across the country come to Houston — they're already coming," Garrou says. "But what's important is they are going to want to co-invest with local investors, and that's the key to venture capital."

While encouraging out-of-city investors is a key part of the equation, Houston does stand well on its own, Milam says. Houston has historically been compared, perhaps wrongly, to Austin., because it got a head start when it came to startup growth. But it's a different story now.

"Austin isn't as advanced as people give it credit for," says Milam. "I don't think Houston at all has [to] look at Austin as a role model or for guidance. Houston has a far better and brighter future when it comes to mobilizing capital and Houston-born startups."

Ultimately, the panelists agreed that despite Houston's slow start and rough waters ahead, Houston's future is bright when it comes to venture capital and startup growth.

"When you look at Houston, we've got a huge economy here — a huge number of customers here," Friday says. "I think we can close the gap of the ratio the amount of venture and startup activity to the overall size of our economy."

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.
