Userpilot

Userpilot is a product growth platform that helps businesses onboard, engage, and retain users on their web and mobile applications. While it doesn't directly offer content publishing like Medium, it provides tools for creating in-app experiences (which can be seen as a form of content), tracking user engagement, and has mobile app capabilities. It lacks features related to public content distribution, monetization for writers, or community feedback on published stories in the same vein as Medium.
