Lean Analytics, AI와 에이전트 시대에 맞춰 돌아보기

AI products fundamentally challenge traditional Lean Analytics by collapsing time-to-value and rendering conventional activation metrics meaningless due to unpredictable output quality. The shift demands redefining engagement from session duration to outcome quality and time allocation, while pricing models must adapt to probabilistic outputs where power users can paradoxically reduce profitability. Understanding these metric transformations is critical for builders to avoid chasing legacy SaaS KPIs that no longer predict success in the AI era.
