# Voice of Customer (VoC)

Voice of Customer (VoC) is a systematic program for collecting, analyzing, and acting on customer feedback across every touchpoint and channel.

VoC programs aggregate structured signals (NPS, CSAT, CES) and unstructured signals (open-text, support tickets, reviews, call transcripts, social media) into a unified view of customer sentiment and need. Mature VoC includes: (1) listening posts at key journey stages; (2) AI-coded thematic analysis of open-text; (3) closed-loop follow-up with detractors; (4) routing of themes to product, support, and marketing owners; (5) executive dashboards with cohort and trend views. Forrester research finds companies with mature VoC outperform peers on revenue growth by 2-3× over five years.

Many VoC channels collect anonymous feedback (https://spaceforms.io/articles/free-survey-maker) — reviews, unattributed forms, and open-text comments — alongside identified signals.

## Example

A B2B SaaS VoC stack: in-app micro-surveys (n ≈ 2,000/mo) + post-support CES (n ≈ 800/mo) + annual relationship NPS (n ≈ 600) + G2 review monitoring + AI coding of 12,000 open-text responses/quarter into 47 themes feeding a weekly cross-functional review.
