Your users are coming back. That doesn't mean you have PMF. Here's the distinction that separates companies that scale from ones that plateau at 10,000 users.

3 key insights
1.

Retention measures whether users come back to what exists. PMF measures whether what exists can grow without manufactured demand. The two diverge sharply at the growth stage — and most Indian founders only discover the gap after spending their Series A.

2.

The clearest PMF signal is not NPS, not retention rate, not revenue. It is organic growth rate at zero paid acquisition. If growth stalls the moment you stop spending on CAC, you have engagement, not fit.

3.

India's startup ecosystem has a structural PMF measurement problem: most founders declare PMF at 10,000 users because cohort retention looks good. The question they haven't answered is whether 10,000 users can become 100,000 without a proportional increase in paid spend.
