01
Find the aha moment
Surface the action with the largest retention gap — not another vanity funnel chart.
PostHog-first · for early-stage SaaS
Find the aha moment.
Diagnose the leak.
Ship with confidence.
idk turns product data into a clear activation diagnosis: the action that separates retained users, where people drop before it, and the smallest next test — so founders stop guessing at PMF.
Demo uses the founder's own product data pattern — activation lift 19% → 44% after shipping the aha change.
02
Diagnose the leak
Map the drop path and classify it as broken, confusing, or missing value.
03
Ship the smallest test
Leave with a prescribed change, confirmatory experiment, and users to interview.
Aha clarity, not more charts.
Built for founders who own activation themselves. Open the demo workspace, run a diagnosis on sample PostHog-shaped data, and walk the full loop in under a minute.
