Is the Pulumi Individual Edition open for use by solo founders operating as a sole proprietership? I can't find anything clarifying whether it's individual (as in hobbyist, nonprofessional) or individual, as in, one person not collaborating with anyone else.
Yes it is open to individual comercial use (companies much larger then sole proprieterships may only have one person doing inferstructure). They also have a version for nonprofits https://www.pulumi.com/pricing/open-source-free-tier/
