Just around a year ago, Houston-based Axiom Space Inc. closed a $100 million series A round. Now, the space tech company has announced even more financing as it grows and scales to support a NASA-commissioned project.

Axiom raised $130 million in its series B round led by C5 Capital with support from TQS Advisors, Declaration Partners, Moelis Dynasty Investments, Washington University in St. Louis, The Venture Collective, Aidenlair Capital, Hemisphere Ventures, and Starbridge Venture Capital.

"Axiom Space is a force in the space sector, and it will become a centerpiece of the C5 Capital portfolio and enhance our vision for a secure global future," says C5 operating partner Rob Meyerson, who will join the Axiom board of directors, in a news release. "The Axiom Station will be the infrastructure upon which we will build many new businesses in space, and it will serve as the foundation for future exploration missions to the Moon, Mars, and beyond."

"Axiom Space was founded on the knowledge that commercial infrastructure and innovation in space would offer unique ways to improve life on Earth," says Axiom co-founder and executive chairman, Kam Ghaffarian, in the release. "Axiom's sole-selection by NASA to connect to ISS and ability to leverage its key revenue lines are evidence of the company's expertise and a business model that is set up to optimize across a variety of commercial on-orbit opportunities.

"This highly successful round is a pivotal moment for on-orbit commerce and its implications for our civilization's potential are far-reaching."

In January 2020, NASA selected Axiom to work on designing and building modules to be attached to the International Space Station. The projects could be ready as early as 2024. Axiom is working to create a commercial space station that would eventually serve as a replacement for ISS. This transformation is expected in late 2028.

In December, Axiom released new details of its 14-acre headquarters near the Houston Spaceport. The HQ is expected to bring more than 1,000 high-paying jobs, from engineers to scientists, mathematicians, and machinists.

The recently raised funding will help support these ongoing Axiom projects.

"We are proud to partner with Axiom's exceptional management team, who built, led, and visited the International Space Station on behalf of NASA and its partners," Brian Stern, a partner at Declaration Partners, says. "The next-generation space station we are building today will be a key means of conducting space-based research, manufacturing, communication, and travel for decades to come."

Axiom Space officially redomiciles its headquarters in Texas

space city

Axiom Space has claimed Houston as its operational home since 2016. And now it can call Texas its official legal headquarters, too.

The spacetech company, which is developing the first commercial space station, Axiom Station, has officially redomiciled its legal headquarters from Delaware to Texas, Axiom announced this week.

Axiom employs approximately 700 people, the majority of whom are in Texas, according to a news release. Its Assembly Integration and Test Facility was built as an anchor of the Houston Spaceport, and the company is also developing next-generation spacesuits at its Houston-based spacesuit lab.

“Texas has demonstrated, consistently and deliberately, that it wants innovative companies to thrive here and has built the policy and regulatory framework accordingly,” Jonathan Cirtain, CEO and president of Axiom Space, said in the release. “For Axiom Space, establishing Texas as both our operational and legal home puts us squarely in a state that understands our mission, supports our industry, and shares in what we are working to achieve.”

Axiom touts Texas's "financial and infrastructural commitments" to the space economy as reasons for the move, including programs and grants from organizations such as the Texas Space Exploration & Aeronautics Research Fund (SEARF), the Texas Space Commission, and the Texas A&M Space Institute.

Axiom was previously awarded a $5.5 million SEARF grant for the development of its orbital data center capabilities last year.

The news comes as energy giant ExxonMobil also announced concrete plans to redomicile its legal headquarters in Texas. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March. The company announced this week that the move would become official July 1. The company's operational headquarters is based in Spring, Texas, a Houston-area suburb.

Houston cleantech, space startups named to World Economic Forum cohort

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."

Houston Methodist receives record $110M gift, names future tower

historic gift

Houston Methodist has received the largest gift in the health system's history to establish new funds for neurological, neuroscience, and women’s health research and treatment.

The $110 million gift comes from Houston-based The Brockman Medical Research Foundation, which supports education and research in the science, medicine and healthcare fields. In response, Houston Methodist announced that it will name its forthcoming 26-story hospital facility the Brockman Centennial Tower.

The tower’s entrance will be named the Anna Margaret Bellows Centennial Hall to honor Anna Margaret Bellows, a young camper who died during the Camp Mystic flooding last summer.

“This extraordinary gift accelerates discovery and transforms how care is delivered,” Dr. Marc Boom, president and CEO of Houston Methodist, said in a news release. “We are grateful to The Brockman Medical Research Foundation for its incredible generosity and vision that will help change the lives of generations of patients. Naming Centennial Tower in recognition of this gift reflects the scale of this commitment and its impact on the future of neuroscience, neurological care and women’s health.”

The gift will be divided into two parts:

  • $100 million will go toward creating an innovation fund within the Houston Methodist Academic Institute and the Houston Methodist Neurological Institute
  • $10 million will be devoted to Houston Methodist's Department of Obstetrics and Gynecology

“This tremendous gift will accelerate translational research that broadens our understanding of neurological and other diseases,” Dr. Jenny Chang, president and CEO of the Houston Methodist Academic Institute, added in the release. “It will allow us to leverage state-of-the-art platforms to detect, diagnose and deliver therapeutics, keeping patient care at the center of our mission.”

The Brockman Centennial Tower is expected to open next year in the Texas Medical Center. Spanning more than 1 million square feet, it will house 400 patient beds, an expanded emergency department, new operating rooms and a rooftop garden. It will be connected to Houston Methodist's flagship Paula and Joseph C. “Rusty” Walter III Tower, which opened in 2018. The Centennial Tower was estimated to cost $1.4 billion when announced in 2022.

In addition to the news of the Brockman gift, Houston Methodist also announced this month that it has launched the Houston Methodist Center for Cell and Gene Therapy and tapped an internationally recognized scientist as its leader.

The new center is focused on discovering and developing innovative and cost-effective therapies for a variety of congenital and acquired diseases, including cancer, HIV and cardiovascular disease.

Dr. Malcolm Brenner has been named as the center's inaugural leader and will assume the role starting in October. He will work alongside scientists and support staff from Baylor College of Medicine and Texas Children's Hospital.

Brenner is a professor of pediatrics, medicine, molecular and human genetics and translational biology at Baylor College of Medicine. He is known for making early advances in using bone marrow transplantation as a form of cell therapy and in engineered immune-cell treatments for cancer and infections, according to a release from Houston Methodist.

“Malcolm Brenner is a pioneer in the field of cell and gene therapy and is uniquely qualified to lead Houston Methodist’s research efforts in this field,” Chang added. “His vision and leadership will play a pivotal role in advancing our work in this space.”
