KISSmetrics is a behavioral analytics tool built for SaaS companies, especially those running product-led growth (PLG). It provides person-level analytics to track individual user journeys, identify actions that predict conversion, and measure time-to-value at a granular level.

KISSmetrics starts with the person, delivering person-level tracking that connects every action a user takes to their identity. This enables behavioral cohort building, PQL definition based on actual usage patterns, and complete journey measurement from first touch to expansion. The platform provides out-of-the-box funnels, cohorts, attribution, and revenue reports without requiring SQL or a data team. Most teams see first insights within 48 hours. Features include self-serve funnels, behavioral tracking, revenue tracking, and PLG-specific analytics for measuring the full self-serve journey from signup to paid conversion. The platform is designed specifically for tracking SaaS customer journeys with person-level insights.
