AI Internet-Meritocracy (there are also several other, less important projects at the same domain) is an app (a beta was released recently) that distributes crypto between scientists and free software authors accordingly AI decisions (there is also human voting to correct over AI failures). This solves the following pain points:
Your task as a marketer is to promote the site and the app. Currently, the most important task of the site is to gather donations.
As a marketer you have the freedom to choose your marketing methodology, but I suppose that you likely should use SEO/GEO.
Note that deep knowledge of science is not required for this role.
Later this volunteer job may lead to paid science marketer position using our fund.
