Building commercial space stations. Haven Demo flew 3 months in orbit (2025-2026). Haven-1 crew launch May 2026. $500M raised (Mar 2026). Founded 2021 by Jed McCaleb.
Vast is a commercial space station company founded in 2021 by Jed McCaleb, the entrepreneur behind Ripple and Stellar, with a mission to build privately owned and operated habitats in low Earth orbit. As NASA's International Space Station approaches decommissioning, Vast is positioned to provide a successor commercial destination for astronauts, researchers, and private space travelers. The company is building a family of modular space stations designed to serve as research platforms, manufacturing facilities, and eventually long-duration human habitation in orbit — the next phase of human spaceflight infrastructure.\n\nVast's initial product is Haven-1, a single-module commercial space station designed for short-duration crew missions. Haven-1 is scheduled for a crewed launch in May 2026 aboard a SpaceX Crew Dragon, making it the first commercial space station to host astronauts. A demonstration version of the Haven module completed a three-month uncrewed orbital mission between 2025 and 2026, validating the platform's life support, power, and structural systems in orbit. Vast is also developing Haven-2, a larger multi-module station intended for longer-duration research and commercial operations.\n\nVast raised $500M in March 2026, bringing total capitalization to over $500M and enabling the company to accelerate station development and expand its mission manifest. The company has partnered with SpaceX for launch and crew transportation services. Vast is competing with Axiom Space and Blue Origin's Orbital Reef project for the commercial space station market, which NASA is funding through its Commercial Low Earth Orbit Destinations (CLD) program as a deliberate strategy to transition human spaceflight from government-owned to commercially operated infrastructure.
a2z Radiology AI raised $20M in 2025 for its whole-body AI that simultaneously screens for 24+ conditions across CT scans — from incidental cancers to cardiovascular risk — in a single automated read.
a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
