Which companies sponsor the most open source projects?

36 companies with 353 publicly visible sponsorships of open source projects and maintainers, counted from GitHub Sponsors, Open Collective, and companies’ own public disclosures. Expand a company to see who they sponsor.

What this measures: breadth, not dollars. GitHub Sponsors hides amounts, so a company sponsoring five projects at $10,000 each ranks below one sponsoring fifty at $10. It also misses support that isn’t publicly visible somewhere: undisclosed grants, foundation memberships, employing maintainers, and free products (tracked separately in the offers directory).
