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."

How Houston innovators played a role in the historic Artemis II splashdown

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month. Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

New 'living pharmacy' biotech company launches out of Rice venture studio

fighting cancer

Rice University’s biotech venture studio RBL LLC has launched a new “living pharmacy” company, Duracyte, designed to make cancer treatment easier on patients.

Backed by an up to $45 million Advanced Research Projects Agency for Health (ARPA-H) award, Duracyte aims to commercialize implantable biohybrid pharmacy devices that are designed to produce therapeutic proteins inside the human body around the clock, replacing the need for regular injections and infusions for some cancer patients.

The company’s main platform is its Hybrid Advanced Molecular Manufacturing Regulator (HAMMR), a rechargeable, implantable device that can sense biological signals, monitor tumor environments and adjust therapeutic output in real time. HAMMR has wireless communication capabilities, which allow patients and clinicians to remotely monitor results through an app every five minutes and make changes to treatment plans without a hosptial visit. Additionally, the device can generate its own oxygen supply, which is key for the therapeutic cells’ survival.

“Biologic medicines such as monoclonal antibodies, cytokines and metabolic regulators already account for a significant share of modern therapeutics, but the way we deliver them today often requires frequent injections or infusions that can be demanding for patients and lead to inconsistent drug levels,” Daniel Anderson, MIT professor and co-founder of Duracyte, said in a news release. “Our vision is to enable a continuous, stable therapy by producing these medicines directly inside the body, which could improve treatment consistency, reduce side effects and ultimately transform how biologic therapies are delivered across many diseases.”

Duracyte’s first clinical trial is slated to begin by the end of 2026 and will focus on recurrent ovarian cancer. The Phase I study will build upon existing work on encapsulated cytokine pharmacy technology, and the company hopes that within a few years this treatment can reach clinical application.

The development of Duracyte is supported by ARPA-H's Targeted Hybrid Oncotherapeutic Regulation (THOR) project, which supports a multidisciplinary research consortium co-led by Omid Veiseh, a professor of bioengineering at Rice. The consortium also includes others at Rice, The University of Texas MD Anderson Cancer Center, Stanford University, Carnegie Mellon University, Northwestern University and the University of Houston, plus industry collaborators like Chicago-based CellTrans.

“What we are building is the culmination of years of progress in cell engineering, biomaterials and implantable device technology,” Veiseh added in the release. “By combining these advances with real-time sensing and adaptive drug delivery, we are working with the support of RBL to create a true ‘living pharmacy’ that can deliver continuous, precisely controlled biologic therapies and fundamentally change how these treatments reach patients.”

RBL launched in 2024 and is based out of Houston’s Texas Medical Center Helix Park. Duracyte is the third company launched by RBL, including Sentinel BioTherapeutics, a clinical-stage immunotherapy company developing localized cytokine therapies for solid tumors, and SteerBio, a regenerative medicine company targeting lymphedema.

“Duracyte exemplifies the kind of breakthrough that Houston’s ecosystem is built to produce,” Paul Wotton, managing partner of RBL LLC and co-founder of Duracyte, added in the release. “With world-class clinical infrastructure, exceptional engineering talent and initiatives like the Texas Biotech Task Force driving alignment across industry, investment and talent, this region is uniquely positioned to move the most ambitious ideas in medicine from concept to patient, faster than anywhere else.”
