Consumer B2c Modeling Insight

Consumer models must distinguish organic from paid growth economics. If your model only works with heavy paid UA, it is a red flag. Show the contribution margin from organic cohorts separately — investors want proof the product has inherent pull.

Consumer B2c Revenue Model

Cohort-based user acquisition model with LTV curves by acquisition vintage. Revenue from in-app purchases, subscription, or advertising driven by DAU/MAU ratio and engagement depth.

Revenue Drivers

  • Monthly Active Users x ARPU
  • In-app purchase revenue by user tier
  • Subscription conversion and retention
  • Viral growth from K-factor (organic new users)

COGS Structure

  • Cloud hosting and infrastructure per MAU
  • Customer support labor and tooling
  • Payment processing fees
  • Content moderation and trust/safety costs

Unit Economics to Model

  • Customer Acquisition Cost (CAC) by channel
  • Day-7 and Day-30 retention as LTV predictor
  • LTV by acquisition cohort at 6, 12, 18 months
  • LTV:CAC ratio target by channel
  • Viral coefficient (K-factor) and payback from organic growth

Key Model Assumptions

Series A models are reviewed by investment committee analysts. Include a data room version with formula audit trail turned on. Avoid hardcoded numbers in cells — every input should flow from the assumption dashboard.

  • Organic vs. paid user acquisition split
  • Day-30 retention rate as primary LTV driver
  • ARPU growth from increasing monetization over time
  • K-factor (viral coefficient) assumption

Funding Scenarios

Three scenarios: upside (125% of plan), base (100%), and downside (70%). Include key assumption levers for each scenario and the capital required in each path.
