Growth and Monetization Case: Venmo (Peer-to-Peer Payments)

Context

You are evaluating growth and monetization drivers for a large U.S. peer-to-peer (P2P) payments app similar to Venmo. Assume "last year" refers to the most recent full calendar year. Use reasonable, clearly stated assumptions.

- Estimate Venmo’s annual revenue for last year. Show a clear framework, state assumptions, and do the math. Provide a base case and a quick sensitivity range.
Weekly metrics for growth and engagement
- Identify the three most important weekly metrics you would track to monitor user growth and engagement.
- Define each metric precisely (event definition, inclusion/exclusion) and explain why it matters.
Experiment design to increase payment frequency
- Propose one concrete experiment to increase payment frequency among existing users.
- Specify hypothesis, eligibility, randomization, primary/secondary metrics, guardrails, sample size/power, duration, and analysis plan. Note any network-effects considerations for P2P.
