Data-Driven Decisions: Beyond Vanity Metrics
2026-01-06
It's tempting to put a graph on a pitch deck that goes up and to the right. But "Total Registered Users" is a vanity metric. It tells you about your marketing, not your product.
Retention is King
The only metric that truly validates product-market fit is Retention.
- Day 1 Retention: Is your onboarding working?
- Day 30 Retention: Is your product solving a recurring problem?
If you can't flatten your retention curve, no amount of top-of-funnel marketing will save the business.
