SpaceNexus is a space industry intelligence platform run by SpaceNexus LLC that tracks launches, satellites, space stocks, funding rounds, contract awards and news for investors, engineers and analysts. The service, launched in 2026, offers profiles of more than 370 space companies, newsletters, an API, embeddable widgets and a space jobs section that aggregates openings from firms such as Planet and Varda Space Industries. Its job feed therefore lists third-party roles in spacecraft engineering, manufacturing, software, legal and operations rather than positions at SpaceNexus itself.
