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."

Rice University scientist earns $600K NSF award to study distractions in the digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

12 Houston climatetech startups join Greentown Labs' growing incubator

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
