Unit Economics & Cohort Summary

Unit profitability and cohort behavior analysis for the VIBEUP platform. Covers LTV, CAC, gross margin, payback, and contribution margin with definitions — plus cohort retention tables by signup quarter. All figures reconciled to the Financial Model and KPI Dashboard.

Methodology

CAC uses fully-loaded S&M spend ÷ new customers. LTV uses 24-month DCF window at 10% discount rate. Gross margin excludes fixed OpEx. Cohort retention tracks % of original cohort paying at each month milestone. Post-launch (Q1 2027+) figures are model projections aligned to 35% QoQ growth target scenario.
