I came across this open source project which might be of interest.
OSS.Fund is a curated and crowdsourced (maintained openly on Github) list of monetization platforms for open source, and other creators. It is created to help independent online creators and builders find the best monetization platform for their needs. The original spreadsheet was started by Bilgin Ibryam with a focus on Open Source Software Funding (hence the name OSS.Fund) but it has expanded to other areas such as writing, blogging, advertising, and other online creators. Any platform that offers any kind of monetization service for online creators is welcome to join in. (www.oss.fund/)
