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.

Axiom Space launches Japanese subsidiary, names leadership

Axiom Space is setting up a Japanese subsidiary to tap into billions of dollars worth of business opportunities in the vast Asia-Pacific region. The company’s new office in Japan will open July 1.

“For the Asia-Pacific region, an Axiom Space presence in Japan means a long-term, direct path to low-Earth orbit for research, for industry, for astronauts, and a partner committed to building that future together with Japan,” Jonathan Cirtain, president and CEO of Axiom Space, said in a news release.

Asia-Pacific spaceflight leaders include Japan, China, India and South Korea.

Until committing to the Asia-Pacific subsidiary, Axiom focused primarily on the U.S. market for space exploration equipment, technology and services. Axiom is building the successor to the International Space Station (ISS), and it provides human spaceflight services and develops next-generation spacesuits.

Fortune Business Insights estimates the Asia-Pacific market for space technology was valued at $155.3 billion in 2025.

“The region is rapidly expanding due to rapidly expanding government space programs, increasing private sector participation, and rising demand for satellite services across densely populated regions,” says Fortune Business Insights, a market research firm.

The region’s combination of strategic investments, market demand and emerging entrepreneurial systems positions Asia-Pacific “for the fastest growth in the global market,” Fortune Business Insights says.

The market research firm pegs the U.S. market for space technology at $251.8 billion in 2025, making it the world’s largest player in that sector.

Veteran Japanese astronaut Koichi Wakata will lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. The Japanese subsidiary will work with government agencies, research institutions, and industrial partners in Japan to expand hardware development and manufacturing, microgravity research and orbital computing.

Wakata was the Japanese space agency’s first program manager for ISS and the station’s first Japanese commander. He also contributed to the construction of ISS, including the Japanese experiment module Kibo. Wakata retired from the Japanese agency, JAXA, in March 2024.

“Japan intends to remain a leading nation in human space exploration post-ISS, and Japanese industry and academia are ready to play a central role in the commercial era,” Axiom Space said in the release. “Axiom Space Japan is how the company will meet that ambition with a long-term, on-the-ground presence.”

As new technologies and approaches develop at breakneck speed, the need for more reliable, affordable energy and power continues to grow dramatically. The current backdrop accentuates the need for Veriten's solution."

Veriten is supported by over 50 strategic partnerships in the energy, power, industrial and technology sectors, including major players like Halliburton and Phillips 66.

"Veriten continues to build a differentiated platform at the intersection of energy, technology and industry expertise," Jeff Miller, chairman and CEO of Halliburton, said in the release. "We were early believers in the team and their ability to identify practical solutions to real challenges across the energy value chain. As all industries increasingly adopt digital tools, automation and AI-enabled technologies to improve performance and execution, we are proud to partner with Veriten again to help accelerate high-impact solutions across the broader energy landscape."

Veriten closed its debut fund, NexTen LP, of $85 million in committed capital in October 2023. It was launched in January 2022 by Maynard Holt, co-founder and former CEO of the energy investment bank Tudor, Pickering, Holt & Co.

It has invested in Houston-based AI-powered electricity analytics provider Amperon and led a $12 million Seed 2 funding round for Houston-based Helix Technologies to scale manufacturing of its energy-efficient commercial HVAC add-on earlier this year. In the past year it has contributed to funding rounds for San Francisco-based Armada and Calgary-based Veerum.

Veriten also named Nick Morriss as its new managing director earlier this month. Morriss most recently served as vice president of business development at next-generation nuclear technology company Natura Resources and spent nearly 20 years at NOV Inc.
