know-if-its-working
Measure GTM with the metrics that matter (net developer retention, DREAM funnel) instead of vanity numbers. Use when the user has dashboards full of stars and pageviews but can't tell if go-to-market is working, or is optimizing acquisition over a leaky bucket.

# Know if it's working
> The only early metric that matters is **net developer retention**. Without it, you're not running a funnel; you're running a colander.
**Use this when:** you're tracking GitHub stars and pageviews and still can't answer "is GTM working?", or you're pouring effort into acquisition while new users quietly churn.
## The core idea
Acquisition is worthless if users don't come back. Prove **retention** first; only then does spending on **acquisition** make sense. Most early founders optimize the top of the funnel while the bottom leaks. Fix that order.
## Framework: net developer retention (Frankl)
> Of all the developers who first used the product in **Month 1**, how many used it in **Month 2? Month 3?**
