The Mixpanel for Startups program gives eligible companies their first year of Mixpanel free on the Startup Plan, which includes every advanced report plus four add-on packages: Data Pipelines, Group Analytics, Warehouse Connectors and Session Replay.
The plan covers 1 billion events per year, 1 million Session Replay recordings, Experiments with 1.2 million MEUs per year, and Feature Flags with 50 flags and 120 million API requests per year. After the first year you can move to the Free, Growth or Enterprise plan; a second free year is not offered.
