Two sites, Quantum Computing and Artificial Intelligence, have or had corporate sponsors (Strangeworks and IBM, respectively). This is part of a pilot program to increase community engagement. From the announcement:
As the biz-dev folks spread the word about these new products, they've actually stirred up quite a bit of interest in our existing communities. Some of these project teams have sizeable communities of their own, so it would be amazing if we could engage these organizations to actively support our current sites — along with the financial resources they bring to finally make our Q&As more attractive for active development again.
It sounds like sponsors are expected to bring both users and money to the table. While I suspect that this is individually negotiated in each case, what are the broad parameters? What's the general ballpark for what sponsors are expected to provide?
If I were an interested company SE would say "contact us and we'll talk", but if I'm a member of a community with ideas about possible sponsors, I can't reasonably approach those companies about it without first having an idea of whether a match would be possible. I don't want to be like those recruiters who spam us all with wildly-off-base job postings; I need to be able to say something better than "I think you'd be good for this site, but I don't know anything more and you'll need to ask them".
So what are the general expectations, so community members can figure out who we should or shouldn't approach for sponsorships?
