Editor's note: This year, recorded over 40 episodes of the Houston Innovators Podcast — a weekly discussion with a Houston innovator, startup founder, investor, and more. I've rounded up seven podcast episodes that stood out for me looking back at the year of recordings. Scroll through to see whom I selected and stream their individual episodes, and tune into the last episode of the year where I explain why I enjoyed each conversation.



Episode 220 - Better than just 'inclusive' - Denise Hamilton of WatchHerWork

Denise Hamilton says she's been used to looking around and realizing she's the only woman or African American in the room, and for the past nine years, she's been providing resources and education to trailblazing women like her. Now, she wants to prepare current and future leaders on how to go beyond inclusivity and work toward indivisibility.

Hamilton's book, "Indivisible: How to Forge Our Differences into a Stronger Future," publishes February 6 from Countryman Press. She explains that the book comes from years of her on personal experiences, as well as inspiration from the women she's met with her company, WatchHerWork, multimedia digital platform providing advice and resources for professional women.

"I've learned a lot of lessons about what skills work, what behaviors are not intuitive, and built WatchHerWork with the intention of creating a space where people can get all of that advice — and juicy goodness — so that they can learn what they needed to do to be authentically successful," Hamilton says on the Houston Innovators Podcast.

"This led to me being brought in as a speaker, and ultimately has led to me becoming an author," she continues. "It's always shocking when people want to listen to what you want to say. It's unbelievable." Continue reading the original article.

Episode 231 - Fostering a collaborative energy transition ecosystem - Barbara Burger

When Barbara Burger moved to Houston a little over a decade ago to lead Chevron Technology Ventures, she wondered why the corporate venture group didn't have much representation from the so-called energy capital of the world.

“I had no companies in my portfolio in CTV from Houston, and I wondered why,” Burger says on the Houston Innovators Podcast.

Much has changed in the ecosystem since then, she says, including growth and development to what the community looks like now.

“There are a few things I’m proud of in the ecosystem here, and one of theme is that it’s a very inclusive ecosystem,” she explains, adding that she means the types of founders — from universities or corporate roles — and the incumbent energy companies. “The worst way to get people to not join a party is to not invite them.”

“No one company or organization is going to solve this. We have to get along,” she continues. “We have to stop thinking that the mode is to compete with each other because the pie is so big and the opportunity is so big to work together — and by and large I do see that happening.” Continue reading the original article.

Episode 233 - How a Houston angel earns their wings - Mitra Miller of Houston Angel Network

One of the biggest components of a well-functioning startup ecosystem is inarguably access to capital, and Mitra Miller is dedicated to enhancing education around investment and growing Houston's investor base.

As vice president and board member of the Houston Angel Network, the oldest angel network in Texas and one of the most active angel networks in the country, Miller strives to provide guidance to new and emerging angel investors as well as founders seeking to raise money from them.

"Most founders have no idea or understanding of how investors think — we are not an ATM," Miller says on the Houston Innovators Podcast. "We are really partners you are getting married to for the next 5, 8, 10 years — sometimes longer. We need to bring your allies in every sense of the word." Continue reading the original article.


Episode 237 - Gearing up for 100x growth - Tim Latimer of Fervo Energy

Geothermal energy has been growing in recognition as a major player in the clean energy mix, and while many might think of it as a new climatetech solution, Tim Latimer, co-founder and CEO of Fervo Energy, knows better.

"Every overnight success is a decade in the making, and I think Fervo, fortunately — and geothermal as a whole — has become much more high profile recently as people realize that it can be a tremendous solution to the challenges that our energy sector and climate are facing," he says on the Houston Innovators Podcast.

In fact, Latimer has been bullish on geothermal as a clean energy source since he quit his job as a drilling engineer in oil and gas to pursue a dual degree program — MBA and master's in earth sciences — at Stanford University. He had decided that, with the reluctance of incumbent energy companies to try new technologies, he was going to figure out how to start his own company. Through the Stanford program and Activate, a nonprofit hardtech program that funded two years of Fervo's research and development, Latimer did just that. Continue reading the original article.

Episode 248 - Houston's beating heart - Dr. William Cohn of The Texas Heart Institute

It's hard to understate the impact Dr. William Cohn has had on cardiovascular health as a surgeon at the Texas Heart Institute or on health care innovation as the director of the Center for Device Innovation at the Texas Medical Center. However, his role as chief medical officer of BiVACOR might be his most significant contribution to health care yet.

The company's Total Artificial Heart is unlike any cardiovascular device that's existed, Cohn explains on the Houston Innovators Podcast. While most devices are used temporarily for patients awaiting a heart transplant, BiVACOR's TAH has the potential to be a permanent solution for the 200,000 patients who die of heart failure annually. Last year, only around 4,000 patients were able to receive heart transplants.

"Artificial hearts historically have had bladders that ejected and filled 144,000 times a day. They work great for temporary support, but no one is suggesting they are permanent devices," Cohn says on the show. Continue reading the original article.

Episode 251 - Building enduring innovation ecosystems - Jon Norby of Anthropy Partners and EconWerx

In his role overseeing startup accelerators for MassChallenge, Jon Nordby started noticing one industry vertical stood out in terms of success and opportunities: Human potential. Now, Nordby is a founding member of an investment firm looking for those opportunities.

Nordby, who served in various leadership roles at MassChallenge — including managing director and head of ecosystems — said he started realizing the opportunities within the organization's space and sports tech programs.

"What we realized over a couple of years running the program was that sports tech as a theme was too limiting," Nordby says on the Houston Innovators Podcast. "We were finding really great technologies, but we were limited at the market size of teams and leagues to deploy those technologies."

"Over the course of that program, we found that the things that were related more to human health and performance tended to out perform all of the other things related to sports tech — like media, entertainment, gambling," Nordby continues. "Still really great markets for those technologies, but we found a lot more traction for human performance." Continue reading the original article.

Episode 263 - Maintaining a legacy of innovation - Reginald DesRoches of Rice University

How does a historic university maintain its legacy while still making room for growth and increased opportunities? That's what Rice University President Reginald DesRoches considers with every decision he makes.

"It's this idea of preserving what's special about the university, while also knowing we need to adapt to a new time, a new Rice, a new time in higher ed, and a new time in society," DesRoches says on the Houston Innovators Podcast. "There's a healthy tension between preserving what Rice is known for — the culture of care, the close-knit community — while knowing that we need to grow, have a global impact, and position Rice on a global scale. It's something that's constantly in my mind to make sure we do both." Continue reading the original article.

The Biden-Harris administration is deploying $150 million as a part of its Cancer Moonshot initiative, and a research team led by Rice University is getting a slice of that pie.

AccessPath is a novel, affordable, slide-free pathology system that helps surgeons determine if they have completely removed tumors during surgery. Rebecca Richards-Kortum, a Rice bioengineering professor and director of the Rice360 Institute for Global Health Technologies, is the lead PI on the project that is receiving up to $18 million over five years from the Advanced Research Projects Agency for Health (ARPA-H).

“Because of its low cost, high speed, and automated analysis, we believe AccessPath can revolutionize real-time surgical guidance, greatly expanding the range of hospitals able to provide accurate intraoperative tumor margin assessment and improving outcomes for all cancer surgery patients,” Richards-Kortum says.

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
