Substack is a platform that helps you to create, publish and distribute your own digital content, including magazines, e-books, and audio and video podcasts. You can also make payments through your digital content and get analytics on your e-book sales. It is a place where you can be as creative as you want, as long as you are making content that is interesting and has value for your audience.

Substack was founded in 2017 by a group of journalists, who wanted to create a platform that would allow them to make a living by their ideas and talents. The idea was to create a place where writers could be their authentic selves and be paid for their work.
