In 1969, Dr. Denton A. Cooley implanted the first total artificial heart in a living patient. Most Houstonians know Cooley’s name, but fewer can name his colleague, Dr. Domingo Liotta, who created the device. Liotta died last year at the age of 97, but his work continues at the Texas Heart Institute.

Meet Yaxin Wang, PhD. The research engineer leads the IDEA Lab at THI. IDEA stands for Innovative Device & Engineering Applications, an apt description of what Wang and her colleagues do. She’s currently focused intensely on projects that could radically change transplantation for patients in need of an artificial heart or new, healthy lungs.

Specifically, Wang is helping to develop a pediatric left ventricular assist device (NeoVAD) to mechanically pump that part of the heart in infants and small children born with heart defects.

“There aren’t a lot of options for very small kids,” explains Wang. “That’s why we’re working on an implantable LVAD for very young kids.”

In fact, as many as 14,000 children with congenital heart disease are hospitalized each year waiting for a new heart, but only around 500 pediatric transplants actually take place.

Essentially, once patients reach their teens, their chest cavities are large enough for an adult donor heart. But smaller children means smaller rib cages and fewer available hearts. For children born with heart disease, Wang’s LVAD could be a lifesaver. Because she has crafted minimally invasive devices that were developed for long-term use, patients could live far longer than before.

The project, funded by a $2.8 million NIH grant, has a big name attached. Dr. O.H. Frazier is a THI legend who claims to have performed 900 LVAD implantations, not to mention some 1,200 heart transplants. In April, the team published their initial findings regarding the success of and improvements in making rotary LVADs over the last half-century.

A different team, also led by Frazier and Wang, received a pair of grants this summer. That includes $2.8 million from the NIH and a total of $7.8 million from a DoD focused program and a THI sub-award. Their work will center on a novel centrifugal left-ventricular assist device intended for end-stage heart failure patients, a potentially safer alternative to a heart transplant.

But Wang isn’t solely focused on the heart. Working with Dr. Gabriel Loor, a cardiothoracic surgeon at Baylor College of Medicine, Wang is also responsible for a method of preserving the lungs for a longer stretch of time, which would allow for further transport, and in the more distant future, potential genetic modification before transplantation. Using animal models for the moment, “they can survive for several hours without any issues,” says Wang.

The pioneering researcher is well on her way to making a name for herself at the Texas Heart Institute and beyond. And soon, she’ll be saving countless lives.

Houston startup lands $10M to power up electrician staffing platform

money moves

Houston-based Buildforce, which provides a tech-enabled staff platform geared toward electricians and electrical contractors, has raised a $10 million Series A round led by Houston’s Saepio Capital.

Other investors in the round include Blue Heron Capital, Revolution’s Rise of the Rest Seed Fund, S3 Ventures and Chicago Ventures.

Buildforce says the funding will help fuel its national expansion and further development of its technology.

The startup, founded in 2019, connects electricians with electrical contractors for commercial and industrial construction projects. Buildforce’s mobile app helps electricians find and carry out work, and a web app helps electrical contractors find and manage electricians.

“This financing is a major milestone in furthering our mission to help people dedicated to a career in the construction trades lead more secure and fulfilling lives,” co-founder and CEO Moody Heard said in a news release.

Buildforce focuses solely on the electrical trade within the construction sector.

Nick Graziano, principal at Blue Heron, says the shortage of electricians is intensifying as demand for electricians accelerates, driven by data center construction, infrastructure development and energy transition initiatives.

The U.S. Bureau of Labor Statistics estimates the U.S. will need to hire about 80,000 new electricians per year through 2032 to catch up with demand. According to the National Electrical Contractors Association, the U.S. is grappling with a current shortage of 50,000 electricians.

A 2026 economic report from asset manager BlackRock says the electrical trade is expected to be the single fastest-growing employment category in the U.S. labor market over the next 10 years.

“Buildforce is capitalizing on a clear opportunity in America’s generational infrastructure buildout. We believe their mission to use technology to improve lives in the construction space will allow them to make a positive long-term impact on a large and important labor market,” added Jaan Bains, managing partner at Saepio Capital.

Venus Aerospace adds government, C-suite leaders following $91M raise​

new leaders

Fresh off its $91 million Series B, Houston-based Venus Aerospace has made several key additions and promotions to its leadership team.

The company says its expanded team will help it deploy its high-thrust rotating detonation rocket engine (RDRE), which completed its first U.S. flight test last summer.

"We flew the world's first high-thrust RDRE in just over four years on $80 million. We believe that makes it the fastest, most capital-efficient rocket engine program in history," Sassie Duggleby, co-founder and CEO of Venus Aerospace, said in a news release. "Adding this talent to our leadership team is how we bring that same discipline to the company itself, as we scale to meet the technical needs of defense and space customers who need range and speed legacy systems can't deliver."

The key hires include:

Lane Bodian, Vice President of Public Policy

Bodian previously served as the Principal Deputy Assistant Secretary of Defense for Legislative Affairs at the Pentagon.

Dan Rebnord, Director of Federal Government Relations

Rebnord most recently served as Senior Policy Advisor to a member of the Senate Armed Services Committee and previously worked in the Office of Legislative Affairs at the Department of Defense and as Staff Director for a national security subcommittee in the House of Representatives. Rebnord and Bodian will lead Venus' work with government stakeholders.

Tom Barron, Chief Operating Officer

Barron was promoted from his role as vice president of operations for Venus Aerospace. Before his time at Venus, he served as Special Assistant to the Secretary of Defense and consulted aerospace clients at McKinsey & Company. He also served as a U.S. Army Infantry and Special Forces officer.

Nick Cardwell, Chief Product Officer

Cardwell was promoted from his role as vice president of research and development. He previously held product and technology leadership roles at VC-backed tech companies in the San Francisco Bay Area and Austin.

Venus also named Cameron Taylor as its new vice president of operations, Sarah Boland Heine as its head of communications, Matt Stohr as its head of business development, and Sheila Menz as general counsel.

The company also announced a joint technology development agreement to advance the RDRE with defense giant Lockheed Martin last week. Through the partnership, Venus and Lockheed will focus on evaluating the RDRE's propulsion architecture in defense systems, specifically for precision fires applications where weapons are designed to accurately strike targets at long distances.

Lockheed Martin Ventures, the investment arm of the aerospace and defense contractor, is an investor in Venus Aerospace.

"Lockheed Martin is focused on rapidly delivering advanced capabilities that strengthen deterrence and provide decisive advantages for the warfighter," Tim Cahill, president, Lockheed Martin Missiles and Fire Control, said in a news release. "Our collaboration with Venus Aerospace allows us to evaluate a promising propulsion technology and determine how it can be integrated into future precision fires solutions. Efforts like this help accelerate innovation, reduce risk and shorten the path from emerging technology to operational capability."

Venus' RDRE is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus says the reusable, affordable and scalable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types. The company has previously estimated that the hypersonic market is projected to surpass $12 billion by 2030.
