Estimate Customer Lifetime Value (CLV) for Spokeo

Context

Spokeo monetizes via consumer subscriptions and possibly one‑off purchases. You are asked to design a practical method to estimate Customer Lifetime Value (CLV) that the team can implement and validate.

Task

Describe:

The data you would require.
The key assumptions (e.g., churn definition, discount rate, margin).
A modeling approach: either a subscription retention/cohort model or a non‑contractual transaction model (e.g., Pareto/NBD + Gamma‑Gamma), and when to use each.
How you would validate the CLV estimates.

Be sure to discuss churn, discount rate, and segmentation.
