WHAT'S NEW IN MIXPANEL
**********************

If you’ve been hoping to move your testing and rollouts to Mixpanel, your wait is over: Experimentation and Feature Flagging are now available on all plans, including Free and Growth.

 

Plus, we’ve deepened AI capabilities in Mixpanel, from intelligent governance to agent improvements. Read on for more details.

********************************************************
Experiments & Feature Flags now on Free and Growth plans
********************************************************

Customers on Free and Growth can now access Mixpanel Experiments and Feature Flags, allowing you to:

*
Move at the speed of AI: Full MCP and Mixpanel Agent support means your AI assistant can propose tests from live metrics, launch them, and interpret the results. No context switching or advanced stats knowledge required
*
Trust every result: Pre-Experiment Bias and SRM checks run automatically, and advanced methodologies like CUPED, Winsorization, Bonferroni, Benjamini-Hochberg are available to keep every experiment statistically sound
*
Target by behavior, not just identity: Roll out to the cohorts and events you already use in Mixpanel
*
Ship with control: Audit trails, multi-environment support, and dynamic config are all included
Both Free & Growth plans come with limited numbers of experiments and feature flags, and Growth plans can add more via Plan Builder.

Tidy up events with AI-powered governance
*****************************************

Is it AddToCart, add_to_cart, or addCart?

 

Use AI-powered data governance to find redundant events and properties to merge. After a merge, all existing reports will correctly tie back to your new merged entity.

 

Clean events in bulk and reduce confusion in reporting.

*********************************************
Ask and you shall receive from Mixpanel Agent
*********************************************

We heard your feedback. We released a round of updates to continue improving Mixpanel Agent as your always-on analyst.

 

With the Agent, you can now:

* Ask your Agent to run a root cause analysis and investigate unexpected behavior directly from the chat window
*
Ask a question and move on. Your Agent keeps working in the background and saves your answer, even if you close the tab, lose connection, or start a new conversation
* Click into any artifact the agent creates—including reports or cohorts—to explore further, refine, or continue your analysis
