My newsletter: https://simonowens.substack.com/   Most people are familiar with newswires like the Associated Press and Reuters, but a much newer upstart called Stacker has devised a new business model for syndicating content. Rather than charging a fee for its articles, it instead gives away its data journalism to any publisher that wants it. It then charges brands a fee to create and distribute sponsored content across the thousands of media outlets that subscribe to its service.   In a recent interview, co-founder Noah Greenberg explained how Stacker works with publishers, its process for creating sponsored content, and why he has no interest in driving an audience to Stacker’s owned and operated website.
