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.”

New innovation hub grows with the addition of 6 Houston startups

moving in

The East End Maker Hub in Houston's East End District is growing with the recent addition of six startups.

"All of these companies cite the East End Maker Hub's physical innovation infrastructure, customizable spaces, strategic location, and potential collaborators as motivations for moving their operations into the hub," Patrick Ezzell, president of Urban Partnerships Community Development Corp., one of the hub's creators, says in an April 26 news release. "All are in the process of growing their teams and view Houston and, more specifically, the East End as a key resource for human capital heading into the future."

The companies that recently joined the East End Maker Hub are:

  • Alchemy Industrial. The company is a contract manufacturer that uses advanced technologies to develop industrial products for the medical, renewable energy, and drone sectors. Mush Khan, a British-born entrepreneur, established the startup last year.
  • CarbonATM. Led by Frank Zamarron and a group of former NASA engineers, CarbonATM aims to improve monitoring of ambient air quality with a low-cost portable device.
  • Gbowo Inc. This startup, founded in 2020, seeks to help companies reduce the environmental and financial costs of last-mile deliveries through the use of low-speed electrical vehicles. Ganiu Ladejobi is the founder and CEO.
  • Horizon Aeromarine. Established in 2020, the startup develops software and electronics from unmanned aerial and marine vehicles. Laura Sammons and Denver Hopkins are the founders.
  • Parallax 621. Founded by Benjamin Peters and Phillip Lentz, the Parallax 621 tech think tank develops technology based on theoretical physics research.
  • Polyvascular. The startup, established in 2014, makes a polymer-based heart valve for children with congenital heart disease.

The East End Maker Hub, at 6501 Navigation Blvd., is a collaboration between TXRX Labs and Urban Partnerships Community Development that houses crafters, fabricators, and tech manufacturers. TXRX Labs invested $1.25 million in equity to set up the hub. Urban Partnerships Community Development raised $35.75 million in capital to get the project off the ground.

Houston startup with life-saving innovation receives $2M grant

for the children

A $2 million federal grant will enable Houston-based PolyVascular to launch human trials of what it hails as the first polymer-based heart valve for children.

In conjunction with the grant, Dr. Will Clifton has joined the medical device company as chief operating officer. He will oversee the grant as principal investigator, and will manage the company's operations and R&D. Clifton is president and co-founder of Houston-based Enventure, a medical innovation incubator and education hub. He previously was senior director of medical affairs at Houston-based Procyrion, a clinical-stage medical device company.

PolyVascular's Phase II grant came from the Small Business Innovation Research (SBIR) program, which promotes technological projects.

The PolyVascular heart valve will help treat congenital heart disease affecting more than 1 million around the world. PolyVascular plans to launch clinical trials of the valve in children 5 and over within two years.

"Congenital heart disease remains the most common category of birth defect and a leading cause of childhood death in the developed world," reads a March 30 news release from PolyVascular, founded in 2014.

PolyVascular says the valve can be implanted without surgery, and can avoid the use of valve replacements from humans or animals. Those valve replacements are difficult to find and often don't last too long, leading to frequent follow-up surgeries.

"Our aim at PolyVascular is to transform the care of children with congenital heart disease by developing an entirely new generation of valves made of medical-grade polymer devoid of any biological tissue," Dr. Henri Justino, chief medical officer at PolyVascular, says in a release. "The valves in use so far for children have been made of biological tissue. Unfortunately, our immune systems target and destroy this biological tissue, sometimes rapidly, rendering the valve ineffective."

The SBIR grant isn't the only win for PolyVascular in recent years.

In 2019, the startup came away with several honors in the 2019 Texas A&M New Ventures Competition. It won the pitch competition (complete with a $5,000 cash award), and received the Biotex Investment Prize, Amerra Visualization Services Prize, and GOOSE Society Investment Prize.

Also in 2019, PolyVascular, a member of TMCx's 2017 medical device cohort, won in the medical device and health disparities and equity categories at the fifth annual Impact Pediatric Health pitch competition. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

Last year, MedTech Innovator, a nonprofit accelerator in the medical technology sector, announced PolyVascular was one of 50 companies chosen to participate in the organization's flagship four-month accelerator program.

"During these uncertain and challenging times, the need for health innovations — specifically those that promise to deliver long-term value to the health care system and patients — is more critical than ever," said Paul Grand, CEO of MedTech Innovator.

Another Houston startup, Vivante Health, also was picked for the MedTech Innovator program. Vivante is a digital health company that helps people address digestive health and wellness.

2 TMCx companies leave SXSW with awards and grant money

Med tech

Two Houston companies are walking away from SXSW with awards and grant funds.

PolyVascular, a member of TMCx's 2017 medical device cohort, won the fifth annual Impact Pediatric Health pitch competition's medical device and health disparities and equity categories. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

PolyVascular co-founder Henri Justino represented his company in three-minute pitch, and team members Dan Harrington and Kwon Soo Chun were also in attendance.

The company was one of 12 finalists in the competition, which took place on March 8 at SXSW in Austin. Among the judges was Houston doctor, Chester Koh, professor of urology, pediatrics, and OB/GYN at Baylor College of Medicine and Pediatric Urologist at Texas Children's Hospital.

"At the Southwest National Pediatric Device Consortium, we are always looking for the next cutting-edge breakthrough in the world of medical devices," says Koh in a release. "Impact Pediatric Health's reputation for bringing together the leaders in pediatric medical technology innovations makes it the perfect venue to help identify and accelerate the next generation of medical device companies impacting our youngest of patients."

Founded in 2014, PolyVascular produces polymeric transcatheter valves for children with congenital heart disease — the most common birth defect and number one cause of infant mortality in the developed world. The company's goal is to reduce that number of infant deaths by introducing a higher quality of valves.

Meanwhile, VastBiome, a 2018 biodesign TMCx company, received a $1,000 grant and is now one of two finalists for the San Francisco-based Illumina Accelerator program. The company works with scientists with ongoing clinical trials focusing on the microbiome as it pertains to therapy.

Another TMCx company, Zibrio, was up for an award in the 2019 SXSW Pitch event, but left the contest empty handed.

TMCx has multiple representatives at the festival, and the organization partnered with Energizing Health to host events throughout the first weekend of the conference.

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.”

AI-powered Houston startup helps restaurants boost customer loyalty

order up

It’s no secret that restaurant trends move fast and margins run thin. And with the proliferation of platforms like Uber Eats, DoorDash and Easy Cater, customer loyalty is fleeting.

The solution?

How about an AI-powered restaurant technology platform that helps restaurant brands cut back on third-party platforms in favor of driving direct discovery, conversion and loyalty?

Enter Saivory. Founded in 2025 by Stephen Klein, a software investor, and Fajita Pete’s restaurateur Hugh Guill, the Houston-based startup aims to help eateries better understand and activate guest behavior across digital channels as AI increasingly reshapes how consumers discover and engage with brands.

In less than a year, Saivory has partnered with Shipley Do-Nuts and Fajita Pete’s to bring AI-powered ordering to life.

“With Saivory, we were able to answer the question of, ‘what if the ordering process could be reduced to a single step, where customers simply tell us what they want and AI takes care of the rest?’” Klein tells InnovationMap.

The Houston-based startup made such an immediate impact that it was selected as a semi-finalist during Start-Up Alley at MURTEC, the restaurant industry’s leading technology conference, which took place last month in Las Vegas.

“Houston is a great hub for technology innovation, and we were proud to represent the city at MURTEC this year,” says Klein. “We didn’t win, but we were able to talk about some of the work that we have existing in the market for clients right now and a little bit about what we’re working on in the future.”

In the current restaurant technology ecosystem, the third-party aggregators own the customer attention that brings volume to restaurants, while also taking big commissions and having control over the end relationships with the customer.

That can often make it difficult for restaurants to grow loyalty and repeat business from customers. Saivory aims to level the playing field for restaurants, helping them stay more connected to their customers.

Take Saivory’s recent application with Shipley’s Do-Nuts, for example.

Saivory powered the donut giant’s AI-ordering and launched Shipley's website and mobile app to support its over 300 locations in Texas alone.

Shipley’s new AI-powered assistant helps users create personalized order recommendations based on individual or group preferences. And unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size. It can also be used for large catering orders.

“They're seeing more traffic to the site and they're seeing when customers use our AI-enabled flows,” Klein says. “And they're seeing higher basket sizes, bigger tickets, by about 25 percent.”

Klein says Saivory’s technology helps strengthen first-party digital relationships, reduce friction and cart abandonment, improve average order value, and delivers personalized, efficient experiences.

“It’s a win-win: the customer gets the right order quickly, while the restaurant gets a bigger margin,” he adds.

Additionally, the technology makes it easier for restaurants to share rewards, loyalty and discounts, ultimately growing more direct traffic and making restaurants less reliant on third-party delivery apps.

Next up for Saivory is adding new components to its platform to enhance the relationship between restaurant and customer, as well as technology around making it easier for restaurants to get found on Google.

“A lot of people are still searching for the best donuts near me,” Klein says. “Or what’s the best Mexican food near me? Customers will increasingly move to AI, where they’re going to ask where they should eat dinner and expect it to just order them dinner. They will eventually expect the technology to know how to do that. So that’s what we’re driving at.”
