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.

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.

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 SaaS to biotech — recently making headlines in Houston innovation.

Dr. Joseph Rogers, the president and CEO of the Texas Heart Institute, is passionate about preventative health care for THI and its patients, as he shares on the Houston Innovators Podcast. What's required is a comprehensive culture shift away from just using a pill to accomplish this goal.

Rogers says health care organizations are going to need to partner with other players — nonprofits, universities, local government — in ways never been done before. And THI is dedicated to this mission.

"Houston is the place to do this," he says. "The reason I think this is such an important community to address this problem is it's the most diverse city in the United States. And I've never lived anywhere or heard of another city that I was so convinced believed they could do anything they set their minds to. It's about making the community aware of the problem and a potential solution — and then working on trying to solve it." Read more.

San Diego, California-based Ascent, a collegiate student loan company that also provides student support services, announced it has acquired Houston-based Ampersand, a software platform that provides skills training to young professionals.

With the acquisition, Allie Danziger, co-founder and CEO of Ampersand, joins Ascent as 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.

“Since launching Ampersand in 2020, we’ve received constant praise from employers, students, and universities on the real education-to-employment skills gap we are filling,” says Danziger in a news release. “I take immense pride in the fact that we’ve helped thousands of students enter the workforce with confidence, earn higher salaries, and get set on the right career path. I know joining the Ascent team will unlock even more opportunities for our combined companies, expanding our collective impact to millions of students and job seekers.” Read more.

Not only is Houston-based nonprofit RioRaiz looking to preserve biodiversity through biotechnology, the innovative organization also wants to offer transformative learning experiences to contribute to a healthier planet.

Led by Jeff Carlson, the president and CEO, RioRaiz's mission is driven by three core pillars: conservation, scientific discovery, and education.

"We have a list of priorities that is cataloged from input from our scientific collaborators, as well as our ability to deliver on our promises to our donors and supporters,” Carlson tells InnovationMap. Read more.

Houston workforce training startup acquired by California company

M&A

A Houston startup, founded to streamline and optimize the intern-company relationship, has been acquired by a student loan and services provider.

San Diego, California-based Ascent, a collegiate student loan company that also provides student support services, announced it has acquired Ampersand, a software platform that provides skills training to young professionals. The news was announced today, July 27, coinciding with National Intern Day.

With the acquisition, Allie Danziger, co-founder and CEO of Ampersand, joins Ascent as 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.

“Since launching Ampersand in 2020, we’ve received constant praise from employers, students, and universities on the real education-to-employment skills gap we are filling,” says Danziger in a news release. “I take immense pride in the fact that we’ve helped thousands of students enter the workforce with confidence, earn higher salaries, and get set on the right career path. I know joining the Ascent team will unlock even more opportunities for our combined companies, expanding our collective impact to millions of students and job seekers.”

The demand for skilled young professionals continues to rise, explains the release, as internship participation declines over time — from 29.2 percent in 2018 to 17.6 percent in 2022, according to a report. Ascent recently announced it plans to roll out initiatives to increase students’ wages by $10 billion in five years. Acquiring Ampersand is one step toward this goal, says Ascent CEO and Co-Founder Ken Ruggiero.

“This move strengthens our ability to maximize outcomes by eliminating the education to employment skills gap, and further positions Ascent as a leader in student success focused on driving positive outcomes,” says Ruggiero in the release. “Ampersand’s custom tools and learning modules will continue to optimize the journey for our customers from classroom to career as they build confidence, secure jobs with livable salaries, and become successful members of the workforce.”

Ampersand's platform, which includes a wide collection of asynchronous professional development training, will be added to Ascent’s existing resources platform, the Student Success Program.

Danziger, who is an expert contributor to InnovationMap on the topics of interns, Gen-Z, and more, has grown her company to facilitate training and internship opportunities to over 7,000 young professionals. Ampersand was also a partner with the City of Houston's Hire Houston Youth program in 2022.

Houston company wins AHA competition for pediatric heart valve design

winner, winner

Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

EO Houston is where ambitious founders go to scale smarter

Don't Go It Alone

Scaling a business from early traction into true growth is one of the most exciting — and punishing — chapters of entrepreneurship. Houston founders know this better than most. Our city is built on ambition: fast-moving industries, talent from around the world, and opportunities that expand as large as the Texas sky.

But as many entrepreneurs eventually learn, scaling isn’t simply “more of what worked.” It requires new systems, new thinking, and often, a new version of the founder. Even the most capable founders eventually face decisions, pressures, and turning points that only other entrepreneurs can truly understand.

Entrepreneurs’ Organization, a global peer-to-peer network of more than 18,000 business owners across 220 chapters in 75+ countries, exists for exactly this stage. One of the largest chapters in the organization, EO Houston brings that global community to life locally, offering founders the connection, learning, and accountability needed to grow sustainably and to grow up as leaders.

A community where founders learn at the highest level
The real value of EO emerges in the lived experiences of other entrepreneurs. When Houston-area founders talk about the moments growth nearly broke their companies, a universal theme appears: you can’t do it alone.

EO Houston member Robert De Los Santos of Sky High Party Rentals learned this the hard way when rapid post-COVID growth made expansion feel limitless — until it wasn’t.

“After COVID, we doubled every year and assumed inventory was the limit. In 2023 we overbought, only to realize demand had peaked. That taught us a hard truth: growth in one city has ceilings. Expanding into Austin and Dallas — the Texas Triangle — gave us new markets to put our inventory to work while we figured out how to penetrate Houston better. The challenge shifted from a strategy of ‘buy more units for demand’ to learning how to tackle the challenges of ‘leading across cities.’”

Founders often enter EO exhausted from trying to maintain control as things grow more complex. Many discover, like Jarred King of Summit Firms, that scaling requires the difficult shift from doing everything to building the team that can.

“We grew quickly because of my network, relationships, and hustle… but I was doing all the work,” King says. “I realized at that point you have to delegate — not just busy work, but important decisions to your key team, as well as set up really effective SOPs.”

“The uncomfortable truth is that you are no longer the best person for most jobs in your company," agrees Darren Randle of Houston Tents & Events. "Your inability to delegate or hire people smarter than you in key leadership and management level roles will become the single biggest drag on the entire business. You have to accept that your original 'hustle' is now a scalability risk."

Making hard decisions, such as walking away from customers or contracts, can feel like less of a sting when you know others have also been faced with tough choices. Aaron Gillaspie of West U's My Salon Suite recalls, “You can’t be everything to everyone, it’s ok to say no, and just understand some customers aren’t the right fit. It’s a two way street and both must win.”

Perspective is perhaps the most important reality check that members find at EO.

“Bigger volume will not make problems go away — you just got to get used to walking the tightrope," says Roger Pombrol of Emerald Standard. "Develop a system for good balance and do not freak out. Scared is no way to live your life. It’s ok if you fall. Your family will still love you. Money is just money. Love is love. The world tries to make you conflate them, but don’t."

Actionable insights from entrepreneurs who’ve already scaled
Conversations like these are happening every month inside EO Forum Meeting. Each EO chapter is divided into several small Forums. These confidential, committed group of 7–10 entrepreneurs who meet to share the real five percent of what they’re experiencing. It’s not advice, but experience — shared candidly, respectfully, and with the kind of vulnerability that leads to breakthroughs.

What makes Forum so impactful is the honesty it draws out. Entrepreneurs are often surrounded by employees, partners, and even family members who rely on them for answers, but seldom do they have a group where vulnerability is not only welcomed, but expected.

Learning experiences that match your ambition
EO supports that growth far beyond peer groups. Through the organization’s global partnerships with institutions like Harvard, Oxford, and INSEAD, Houston members gain access to executive-level learning experiences designed specifically for entrepreneurs.

These programs help founders step out of the day-to-day and think strategically about competitive advantage, innovation, and organizational leadership. Paired with ongoing learning through EO Jumpstart, Nano Learning, and its global library of member-created content, founders stay informed, challenged, and ahead of emerging trends.

And through global communities — ranging from EO Women and EO Under 35 to industry-specific groups — Houston members tap into expertise that spans continents and sectors. Whether someone is navigating M&A, exploring international expansion, or integrating new technologies, the right perspectives are always within reach.

What truly distinguishes EO Houston, however, is its culture. Houston’s entrepreneurial landscape is uniquely diverse and resilient, filled with founders who are hungry to build, innovate, and elevate the city’s business community. EO Houston amplifies that spirit, creating relationships that are as supportive as they are strategic. Many members describe the chapter not simply as a network, but as a catalyst for becoming better leaders, better thinkers, and — just as importantly — better human beings.

Your next level starts here
For entrepreneurs who are ready to scale—beyond their first million, beyond their current comfort zone, and toward a future that requires sharper leadership and stronger community—EO Houston offers an unmatched platform. It is a place where ambitious founders grow faster, think bigger, and gain the confidence to take bold next steps.

If you’re ready to elevate your business and your leadership alongside people who understand the journey, EO Houston is ready to welcome you. Your next level starts with the peers who can help you reach it. Learn more and become a member here.

3 Houston companies land on Deloitte’s Technology Fast 500 list

trending up

Three Houston companies have made this year’s Deloitte North America Technology Fast 500 list.

The report ranks the fastest-growing technology, media, telecommunications, life sciences, fintech, and energy tech companies in North America. The Houston companies to make the list, along with their revenue growth rates from 2021-2024, include:

  • No. 16 Action1 Corp., a provider of cybersecurity software. Growth rate: 7,265 percent
  • No. 92 Cart.com, a commerce and logistics platform. Growth rate: 1,053 percent
  • No. 312 Tellihealth, a remote health care platform. Growth rate: 244 percent

“Houston’s unique blend of entrepreneurial energy and innovation continues to strengthen the local business community, and I’m thrilled to see Houston companies honored on the 2025 Deloitte Technology Fast 500 list. Congratulations to all the winners,” said Melinda Yee, managing partner in Deloitte’s Houston office.

Action1 is no stranger to lists like the Deloitte Technology Fast 500. For instance, the company ranked first among software companies and 29th overall on this year’s Inc. 5000, a list of the country’s fastest-growing private companies. Its growth rate from 2021 to 2024 reached 7,188 percent.

Mike Walters, president and co-founder of Action1, said in August that the Inc. 5000 achievement “reflects the dedication of Action1’s global team, who continue to execute against an ambitious vision: a world where cyberattacks exploiting vulnerabilities are entirely prevented across all types of devices, operating systems, and applications.”

Atlanta-based Impericus, operator of an AI-powered platform that connects health care providers with pharmaceutical and life sciences companies, topped the Deloitte list with a 2021-24 growth rate of 29,738 percent.

“Our mission is to set the standard for ethical AI-powered physician connections to pharma resources, accelerating and expanding patient access to needed treatments,” said Dr. Osama Hashmi, a dermatologist who’s co-founder and CEO of Impiricus. “As we continue to innovate quickly, we remain committed to building ethical bridges across this vital ecosystem.”
