Six usage signals that predict free-to-paid conversion

Login frequency is a weak predictor on its own — plenty of accounts log in daily and never convert. The signals that matter tend to involve friction: hitting a usage limit, inviting a teammate, or connecting a second tool.

Team seat growth is one of the strongest early indicators. An account that goes from one user to three within the trial window is telling you the tool has already spread past its original champion.

Integration connections matter almost as much. Wiring up a CRM or data warehouse is a small piece of switching cost a free user wouldn't normally pay unless they expected to stick around.
