Failure Mode 1: Stale Data
You bought a dataset or you are enriching from a provider that caches profiles. The data was accurate when collected — maybe. But people change jobs every 2.5 years on average. Company headcounts shift quarterly. Titles change constantly. By the time your AI agent uses that record, it is already wrong. The email bounces. The personalization references a job the prospect left six months ago. Your user sees a broken product.
