Definition

A funnel is an ordered sequence of events: signup → activate → first_payment. The funnel chart shows what percentage of users reach each step. PostHog, Mixpanel, Amplitude, and most product analytics tools all expose them.

How drift breaks funnels

Funnels are bound to exact event names. Rename one event in the sequence and that step shows zero conversion overnight. Drop an event mid-funnel and the steps after it can never be reached.
