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.”

University of Houston receives funding to support diverse cardiovascular researchers

pumping up innovation

University of Houston professors have received a nearly $800,000 grant to create a new summer program that will support diverse future researchers.

The National Heart, Lung, and Blood Institute provided $792,900 in grant funding to Bradley McConnell, professor of pharmacology at the UH College of Pharmacy, and Tho Tran, research assistant professor of chemistry at the UH College of Natural Sciences and Mathematics.

The funding will go toward created a summer program called the University of Houston Cardiovascular Undergraduate Research Experience, or UH-CURE. Ten undergraduate students per year will be selected for five years in cardiovascular research across disciplinary lines.

"We are so grateful to be able to provide talented students across the U.S. an opportunity to experience our excellent cardiovascular research environment,” Tran says in a news release. “We want UH-CURE participants to gain confidence in their research abilities through our hands-on approach and the skillset to navigate future challenges through our professional training.”

The goal is to increase students’ interest in cardiovascular research, and students have the opportunity to receive a $6,000 stipend, travel to a globally recognized cardiovascular research conference, and take part in on-campus housing and a food allowance. The summer program will also try to develop research skills, increase awareness of transdisciplinary research, promote diversity and collaborations, cultivate transferable skills necessary for succeeding in graduate school and help facilitate undergraduate students to pursue further training in cardiovascular research.

The program will integrate students into a research lab where they will learn research skills, data analysis, and research integrity. The program will be under the mentorship of a faculty member from across UH’s colleges, and include workshop and enrichment activities.

McConnell and Tran previously formed the American Heart Association-funded UH-HEART pilot program, which focused on cardiovascular research. They expanded on that initiative with UH-CURE, which includes cardiovascular research across disciplinary lines from community engagement and population-based research to basic, translational, and applied research. UH-CURE also helps prepare for careers in cardiovascular research.

“We all know that a diverse environment leads to a much better generation of ideas and solutions,” Tran adds. “We hope to bring that strength to the future of cardiovascular research through our students.”

Innovative Houston urban farm scores national award for green work

to the moon

A Houston urban farm has earned national recognition for its innovative approach to water conservation. Moonflower Farms won the American Heart Association's Foodscape Innovation Excellence Award, which recognizes positive changes in the foodscape, a term for all of the places where food is produced, purchased, or consumed.

The Heart Association selected Moonflower's submission, titled "Sustainable Farming Through Water Conservation," from 26 entries. Dallas' Restorative Farms earns the Foodscape Innovation Consumer Choice Award.

"These two innovations demonstrate a way of producing food that promotes affordability and equitable access, and the American Heart Association is proud to recognize these efforts," AHA chief medical officer for prevention Eduardo Sanchez said in a release.

Located in a 20,000-square-foot greenhouse south of downtown, Moonflower operates what it describes as Houston's first vertical indoor farm. The method both reduces the amount of space needed to grow the farm's microgreens, lettuces, herbs and edible flowers and it eliminates the disruptions caused by adverse weather conditions, which allows the farm to produce year round.

Moonflower uses a closed-loop system for capturing rainwater to feed its crops. The water is treated and oxygenated so that it can be reused. Not having to pay for water from the City of Houston allows the farm to operate more economically and sell its produce at an affordable price to restaurants and individuals.

"Our hydroponic farm uses 90-percent less water than conventional farms," Moonflower founder and CEO Federico Marques said in a statement. "We provide year-round produce to residents in historically underserved communities and donate produce to local charitable food systems."

One of those charities is Houston non-profit Second Servings, which "rescues" food from restaurants and events and distributes it to food pantries and other resources.

"The donations we receive from Moonflower Farms are incredible," Second Servings founder and president Barbara Bronstein said. "Their hydroponically grown greens are so appreciated by the needy Houstonians we serve, who lack affordable, convenient access to fresh produce."

Recently, Moonflower introduced a SupaGreens subscription box that allows customers to purchase greens weekly, bimonthly, or monthly. The box is delivered directly to consumers.

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.”

seeing green

Houston-based investment firm Veriten has announced the initial close of its second flagship energy venture fund with more than $105 million in capital commitments.

Fund II will build on Veriten’s initial fund and aim to support “scalable technology solutions for energy, power and industrial applications,” according to a company news release.

"Our differentiated network, research-driven process, and first principles approach to investing are having an impact across multiple verticals including traditional energy, electrification, and industrial technology. Fund II builds on that platform,” John Sommers, partner, investments at Veriten, added in the release. “In this environment, the differentiator isn't capital – it's all about connectivity, deep sector expertise, and an economically-driven approach. 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.
