Platforms that unify customer signals across touchpoints — surveys, NPS, support interactions, product usage, and social — to measure, analyze, and improve the end-to-end customer experience. Core capabilities include multi-channel feedback collection, journey mapping and orchestration, sentiment and text analytics, experience dashboards, closed-loop action workflows (alerting the right team when experience degrades), and benchmarking. The category operates at the experience measurement and improvement layer, distinct from operational CS platforms.
