Ask HN: How to contact sponsors for Open Source?

I am creating https://serverjs.io/ and would love to have some sponsors [1] to assure that I can maintain the project long-term (while at the same time validating the demand). My thinking was: 0. Great idea, initial prototype and a track of open source commitment and deliverables [2] => done 1. Find mid-large companies interested in Node.js => done 2. Contact those companies to offer sponsorship with perks => HOW? 3. Keep working and improving the project The problem is that those companies that can drop some money on a project like this seems like a unreachable fortification when trying to contact them. Some times I even have to go through many loops even just to get a generic support email. I have also tried contacting few individuals who work at some of those companies with no answer at all. So two questions: - Who/what channel to contact companies in Node.js world committed to OSS. - How to properly communicate this? I do not want to SPAM anyone, just letting them know what I am working on and how it can benefit them for sponsoring server.js Notes: assume I am effectively isolated from anyone working at a big tech company since I am from Spain and the only US devs I know are freelancers as well.
