Every signup reaches activation, so this step is not the immediate constraint.
Pre-aha conversion evidence
Aha Funnel Analyzer
Turn event rows into a bounded cohort funnel, then investigate the break closest to your North Star event first.
Illustrative sample. No Amplitude, Mixpanel, account, revenue, experiment, or live product data is connected.
Load the bundled events or paste your own CSV.

Worked decision
Fix the edge before the aha event, then work backward.
Only half of activated users transact: two users and fifty percentage points are lost.
Investigate activated -> transaction before changing earlier signup or activation behavior.
Which edge gets the first investigation?
Run the sample, then apply the prioritization rule.
Conversion shows where. It does not explain why.
The tool describes supplied events and ordered stage membership. It does not infer causal friction, forecast revenue, verify tracking quality, or replace an experiment.
