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.

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
