Houston-based Solugen secured financing from the U.S. Department of Energy's Loan Programs Office in June to support its mission of producing clean chemicals.

According to Solugen, the facility is expected to reduce annual carbon emissions by up to 18 million kilograms.

"American manufacturing is at a turning point, and we are proud to have the opportunity to work with the DOE in bringing critical chemical production capabilities onshore to communities like Marshall," Gaurab Chakrabarti, CEO of Solugen, says in a news release.

Houston-born and bred medical device company, Procyrion, has completed its series E with a raise of $57.7 million, including the conversion of $10 million of interim financing.

Procyrion is the company behind Aortix, a pump designed to be placed in the descending thoracic aorta of heart failure patients, which has been shown to improve cardiac performance in seriously ill subjects. The money raised will allow the company to proceed with a the DRAIN-HF Study, a pivotal trial that will be used for eventual FDA approval and commercialization.

The Aortix is the brainchild of Houston cardiologist Reynolds Delgado. According to Procyrion’s CSO, Jace Heuring, Delgado, gained some of his experience with devices for the heart working with legendary Texas Heart Institute surgeon O.H. “Bud” Frazier. He filed his first patents related to the Aortix in 2005. Read more about the round.

The powerful partnership between Texas Medical Center (TMC) innovation and the world of Korean biotech advancement is already growing in scope. Just six months after the new TMC Republic of Korea BioBridge was first announced, 12 new companies from the Republic of Korea will establish on-site presences in Houston to further collaboration between the two nations and medical industries.

The expansion comes from a new agreement between TMC and the Korea Health Industry Development Institute (KHIDI). William McKeon, president and CEO of Texas Medical Center, applauded the move and predicted it would benefit both Houston and Korea immensely.

“Korea has established itself as a global leader in biohealth innovation, with a growing pipeline of breakthrough technologies across digital health, biotechnology, and medical devices,” McKeon said in the news release. “Through the TMC Korea BioBridge, we are creating a direct connection between Korea’s innovators and the world’s largest medical city. This collaboration between TMC and KHIDI provides companies with a place to establish a presence, build strategic relationships, engage with leading clinicians and researchers, and accelerate the path toward commercialization and patient impact in the United States.”

The companies that will be in residence at the TMC Innovation Factory include Ardens Lifescience, whose new CAROL device is currently in human trials tackling lung cancer by using the airway network as electrodes to perform bronchoscopic ablation; stem cell-based gene therapy firm CELLeBRAIN, currently working on neurological disorders and solid cancers; and Wellysis, the developer of the S-Patch wearable cardiac monitoring device.

Additional companies include:

  • Antigravity
  • ARPI
  • CTCELLS
  • elecell
  • HUVER Inc.
  • Hutom
  • ORGANOIDSCIENCES
  • YOUTH BIO GLOBAL
  • Seoul Medical Informatics Intelligence Lab Inc.

“This collaboration establishes a strong foundation for connecting Korea’s biohealth innovation ecosystem with world-class clinical and innovation resources in the United States,” Younghun Jeong, executive director of the KHIDI, added in the news release. “Through partnerships with Texas Medical Center and the Korean-American Medical Association Texas, we look forward to fostering meaningful collaboration among innovators, clinicians, and industry leaders while creating new opportunities for clinical validation, commercialization, and global growth. KHIDI remains committed to expanding global partnerships that support biohealth innovation, clinical collaboration, commercialization, and international growth.”

This is the seventh international strategic partnership for the TMC. It launched its first BioBridge with the Health Informatics Society of Australia in 2016. It launched its TMC Japan BioBridge, focused on advancing cancer treatments, last year. It also has BioBridge partnerships with the Netherlands, Ireland, Denmark and the United Kingdom.

Venus Aerospace closes $91 million Series B to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine 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 Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.
