About
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.
NYSE-listed federal IT and electronic warfare contractor. ~$6–7B revenue; 23,000+ employees. Fastest-growing major defense prime by pivoting into EW hardware and SIGINT systems.
About
CACI International is a defense and federal IT company founded in 1962 and headquartered in Reston, Virginia, trading on the NYSE under ticker CACI. With annual revenues in the $6–7 billion range and over 23,000 employees, CACI is recognized as one of the fastest-growing defense prime contractors, having successfully pivoted from pure IT services into high-margin electronic warfare (EW) and signals intelligence hardware.\n\nCACi's core portfolio spans intelligence solutions, SIGINT, electronic warfare systems, C5ISR (Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance), cloud modernization, and enterprise IT. The company's move into EW hardware has differentiated it from peers and driven above-market growth, including wins on DoD programs requiring domestically produced EW systems. CACI has bolstered its hardware and spectrum capabilities through strategic acquisitions including LGS Innovations in 2018.\n\nCACi serves customers across the military branches, intelligence community, and DHS. The company is frequently named to Washington Technology's Top 100 Government Contractors list and has a strong competitive position in contested-environment warfare systems—a direct beneficiary of DoD's increased spending on multi-domain operations and spectrum warfare.
