Cohort Funnel Analyzer

Compares funnel progression by acquisition cohort and source, then lets users narrow the view with cohort and source filters before switching the chart between won-count and retention views. The dashboard summarizes each cohort-source pair with visits, qualified, SQL, won, completion rate, attributed revenue, and the largest stage leak, making it easy to spot which cohorts are converting cleanly and which ones are leaking earlier in the funnel.

A detailed focus panel breaks the selected cohort-source pair into stage-by-stage conversion and retention so users can inspect how much volume is lost between each step. The app also includes a deterministic snapshot form for adding new cohort-stage rows into the workbook, and it keeps starter data visible in preview mode until the host rows are loaded through the bf API.
