For products where value emerges from collaboration, a team invitation that is accepted — not just sent — is one of the strongest early retention predictors. Solo use rarely survives 90 days in team-dependent products.

Doing the main thing once is setup. Doing it twice is a signal. Completing the core workflow more than once in the first two weeks indicates the user found the value and returned to it deliberately.

Users who return with shallow sessions — a quick login and exit — are often on their way to churning. Deep sessions with multiple feature interactions per return visit suggest the product has entered the user's workflow.

When the product's value depends on live data, connecting a source or integration is the prerequisite for any real activation. Users who connect a data source create a switching cost that makes churn more expensive before they even realize it.
