Upbound is the company behind Crossplane, an open-source framework that platform teams use to manage cloud infrastructure as control planes. Upbound sells a commercial platform for building, running and governing those control planes, aimed at platform engineers, automation and AI agents. According to the vendor, the full platform can run anywhere, including air-gapped environments. Crossplane graduated as a CNCF project in November 2025.
Upbound was founded in 2017 and is headquartered in Seattle, Washington, US. Its Series B round in 2021 was led by Altimeter Capital, with GV and Intel Capital participating; no majority owner is named. Crossplane is open source, whereas the Upbound platform is a commercial product. For a European organisation, the vendor's US base and its unpublished hosting locations are the points to check. Organisations that prefer to avoid vendor hosting can run the open-source Crossplane themselves, but the commercial platform's deployment terms should be reviewed before purchase.
