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 doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
