Houston innovators talked big topics at SXSW 2024 — from the startup scaling and converging industries to the future of work.

Houston House, which was put on by the Greater Houston Partnership on March 11, hosted four panels full of experts from Houston. If you missed the day-long activation, here are some highlights from the experts who each commented on the future of the Bayou City when it comes to startups, technology, innovation, and the next generation's workforce.

"When we think about Houston, we think about access to at-scale infrastructure, amenities, and workforce and talent pools."

— Remington Tonar, co-founder and chief growth officer at Cart.com, says about why the company chose to return its headquarters back to Houston last year. One of these amenities, Tonar explained, is Houston's global airports.

"If New York and Austin had a baby, it would be Houston, because you have friendly people with a big-city culture."

— Mitra Miller, vice president and board member of Houston Angel Network, says, adding that Houston has a cost efficiency to it, which should be at the forefront of founders' minds when considering where to locate.

"We are not only attracting global talents, we are also attracting global wealth and foreign investments because we are the rising city of the future. We are the global launch pad where you can scale internationally very quickly."

— Sunny Zhang, founder of TrueLeap, says adding how there's a redistribution of global workforce happening when you consider ongoing global affairs.

"We overwhelmingly as a company, and my co-founder would agree, knew we had to go the Houston path. And we started funneling a lot more resources here."

— Carolyn Rodz, co-founder and CEO of Hello Alice, says, explaining that the pandemic helped equalize the talent across the country, and this has been to the benefit of cities like Houston.

"Houston is here with arms open, welcoming people and actively recruiting."

— Sean Kelly, co-founder and CEO of Amperon, says, emphasizing how Texas has made moves to being business friendly. Amperon was founded in New York, before moving to Houston a couple years ago.

"There is a revolution starting to happen in Houston right now."

— Trevor Best, co-founder and CEO of Syzygy Plasmonics, says, first commenting on the momentum from Rice University, where his company's technology originates from. But, as he adds, when you compare the ecosystem when the startup was founded in 2019 to where it's at now, "there is so much more happening."

"Houston has a critical mass in terms of aerospace."

— Stephanie Munez Murphy of Aegus Aerospace says, saying specifically that NASA's Johnson Space Center holds some responsibility for that. "JSC is the home of opening up space commercialization."

"There's diversity in industries people are coming from, but also in terms of experience and expertise that (Houstonians) have."

— Robyn Cardwell of Omniscience says, adding that Houston's diversity goes further than just where people originate from. "Houston has all these pieces put together ... for growing and scaling organizations," she adds.

"I've worked with thousands of students in Houston who are actively looking to better themselves and grow their career post college or post high school and go into the workforce."

— Allie Danziger of Ascent Funding says, adding that Gen Z, which is already entering the workforce, is entrepreneurial and ready to change the world. "Seeing the energy of Houstonians is just thrilling," she adds.

"We're working together in the Houston community. ... There are so many opportunities to collaborate but we need conveners." 

— Stacy Putman of INEOS says, adding that within industry there has been a lack of discussion and collaboration because of competition. But, as she's observing, that's changing thanks to conveners at colleges or at the Greater Houston Partnership.

"The opportunity for Houston is that everybody has to step up to be in some way, shape, or form helping us with this."

— Raj Salhotra of Momentum Education says about supporting the future workforce of Houston, including low-income household students.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from education to space tech — recently making headlines in Houston innovation.

For the second time in less than six years, Houston entrepreneur Allie Danziger has navigated a company through an exit. But, with the two exists under her belt, Danziger says the two transactions could not be any more different.

Danziger founded Integrate Agency, a digital-focused public relations firm, in 2009 and sold it to another marketing and PR firm based in Austin in 2018. She founded her next company, Ampersand Professionals, in 2020 to address the challenges for upskilling young professionals to prepare them for success in the workplace — something employers really wanted, but struggled to do consistently.

Last month, Ampersand was acquired by Ascent Funding, a college loan provider that's building out a platform to support its college-aged borrowers. In this week's episode of the Houston Innovators Podcast, Danziger shares how this opportunity came about and looks back on these two pivotal deals. Read more.

Rice University’s Office of Innovation has named Houston materials scientist-turned-entrepreneur Adrian Trömel as its new assistant vice president for strategy and investments.

Trömel founded non-invasive neurostimulation medical device company CNX Medical at the Texas Medical Innovation Institute in 2019 and most recently served as chief growth officer for Hamilton Health Box, which brings an on-site care team to company offices.

In his new role, Trömel will oversee the creation of the Rice Nexus, an innovation hub within the Ion that aims to bridge the gap between the university and Houston's innovation ecosystem. He will also lead the creation of a translational research grant fund and a university-affiliated venture fund for Rice-affiliated entrepreneurs. Read more.

Houston has another unicorn — a company valued at $1 billion or more — thanks to a recent round of funding.

Axiom Space released the news this week that it's closed its series C round of funding to the tune of $350 million. While the company didn't release its valuation, it confirmed to Bloomberg that it's over the $1 billion threshold. Axiom reports that, according to available data, it's now raised the second-most funding of any private space company in 2023 behind SpaceX.

Saudi Arabia-based Aljazira Capital and South Korea-based Boryung Co. led the round. To date, Axiom has raised over $505 million with $2.2 billion in customer contracts, according to the company.

“We are honored to team with investors like Aljazira Capital, Boryung and others, who are committed to realizing the Axiom Space vision,” Axiom Space CEO and president Michael Suffredini says in a news release. “Together, we are working to serve innovators in medicine, materials science, and on-orbit infrastructure who represent billions of dollars in demand over the coming decade.Read more.

How this Houston edtech startup's acquisition is primed to further advance platform reach, impact

HOUSTON INNOVATORS PODCAST EPISODE 200

For the second time in less than six years, Houston entrepreneur Allie Danziger has navigated a company through an exit. But, with the two exists under her belt, Danziger says the two transactions could not be any more different.

Danziger founded Integrate Agency, a digital-focused public relations firm, in 2009 and sold it to another marketing and PR firm based in Austin in 2018. She founded her next company, Ampersand Professionals, in 2020 to address the challenges for upskilling young professionals to prepare them for success in the workplace — something employers really wanted, but struggled to do consistently.

Last month, Ampersand was acquired by Ascent Funding, a college loan provider that's building out a platform to support its college-aged borrowers. In this week's episode of the Houston Innovators Podcast, Danziger shares how this opportunity came about and looks back on these two pivotal deals.

"Integrate definitely was not built to sell — I didn't even know that people sold businesses when I was 24 (and started the agency," Danziger, who worked in PR her entire career at that time, says, adding that she thought she'd work at the company her whole life before passing it down to her children. "It ended up being a life-changing experience and opportunity because it did open my eyes up to other other things that I could do professionally — and also just kind of like the way that businesses are structured and run."

One of those things she considered post acquisition was upskilling entry-level employees. At Integrate, she hired a lot of interns and recent college graduates. She recognized there was a gap in the market. The first problem she identified was the need to match interns to positions at companies in an optimized way. While that's how the company started, it pivoted as Danziger says she saw the bigger need not for finding interns, but for making sure they were ready for their positions from the start.

"Most business leaders need their interns and entry-level employees starting day one with an understanding of how to communicate, and they don't really have the resources to teach them some of these skills," she explains.

Once the Ampersand platform, which has tons of resources and hours of instruction loaded on it, the challenge was finding the stakeholders that wanted the platform to exist — her potential customers. Was it the colleges or the employers? Through this journey, she realized that college loan lenders are part of that equation too.

"The lenders — the ones who are giving the student loans — they're the ones who really need them to be successful in the workplace," Danziger explains, saying the success of their loan recipients ensures a timely payout for the lender. "Their business model is predicated on students being successful, and I'd always known that, but not quite known what to do with that knowledge."

Danziger says the idea for acquisition, while always in the back of her mind, really became a possibility when she went out to raise funding.

"You're always raising money, and you're always for sale," Danziger says of the startup journey.

When a potential investor raised the idea of being a potential acquirer, Danziger says she started doing some soul searching. The right acquisition deal could help her address the milestones she wanted to reach with investment funding — growing her team, expanding her technology, and broadening reach. Through a diligent process, Danziger decided on Ascent from a few other potential acquirers.

"I'm not going anywhere. I want to still keep solving this problem, but with a larger team and larger resources," she says. "Either I could go find that myself, or I could join forces we could join forces with an established organization."

Danziger says her role at Ascent is still being constructed in terms of scope and responsibilities, but her title as of now is senior vice president and general manager of student success. She will lead the company's educational program that focuses on equipping students with skills from education to employment.

She shares more on the acquisition process — including her advice to startups thinking about the M&A path. Listen to the interview here — or wherever you stream your podcasts — and subscribe for weekly episodes.

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.”
