Mixpanel

Mixpanel is an analytics tool focused on user behavior (product analytics) inside web and mobile apps. It is built by the company of the same name and used by tens of thousands of product teams worldwide. It is a great fit for SaaS founders, product managers, marketers and growth teams who want to decide based on data instead of gut feeling.

It works on the principle of event tracking: you add a short snippet or connect an SDK, and Mixpanel records specific actions such as sign-ups, button clicks, completed purchases or form submissions. The inputs are these events together with user properties, and the outputs are clear charts, funnels, retention reports and segments that show where people continue and where they drop off.
