114 organizations behind the repositories GitGenius analyzes

Companies, foundations, communities and research groups, mapped to the GitHub organizations they own (registry v0.3.0).

Counts are of repositories in the GitGenius catalogue attributed to an organization's GitHub organizations. They are a floor, not a total: an organization owns repositories we have not catalogued, and work published under an individual's own account is never attributed to their employer. How this is built.

33 more organizations are in the registry with fewer than 5 catalogued repositories and have no page yet.
