Evaluate a Claimed Viral Loop

Problem

Scenario

You're evaluating a product that appears to be growing through user sharing and invites. A founder says the product has a strong viral loop, and you want to test whether that claim reflects durable, self-sustaining growth or just a burst of acquisition.

Question

How would you evaluate a founder's claim that their product has a strong viral loop?

What makes this hard

  • Invite volume alone can look impressive without producing retained users.
  • Referral growth can be confused with paid, founder-led, or campaign-driven acquisition.
  • A loop can work for one segment or surface without being product-wide.
  • The speed of the loop matters, not just the total output.
