PostHog-first · Early-stage SaaS

Find the aha moment.
Diagnose the leak.
Ship with confidence.

idk is an AI product analyst for founders pre-PMF. Connect PostHog, get the action that drives retention, the drop path before it, a leak class, and the smallest next test — not another chart graveyard.

Built for founders who own activation — under ~5k users, PostHog in the stack.

The loop

Aha clarity, not more charts.

Early founders run the same painful cycle: see drop → guess cause → guess fix → ship → wait. idk encodes the full diagnosis end-to-end so you ship the right class of change first.

  1. 01

    Find the aha

    Connect PostHog. idk ranks the action with the largest retention gap — your real aha moment, not a vanity metric.

  2. 02

    Map the drop

    See exactly where users fall off before that moment, step by step on the path that actually matters.

  3. 03

    Classify the leak

    Broken, confusing, or missing value. Honest labels so you stop shipping the wrong class of fix.

  4. 04

    Prescribe the test

    Get the smallest confirmatory change, the experiment to run, and the exact users to interview next.

Lived proof

From 19% to 44% activation — on real product data.

The founder killed a prior AI learning app on its own metrics (~400 users, ~80% churn), reverse-engineered the universal founder loop, then rebuilt that loop into idk. An internal demo already rediscovers the same aha-moment insight that lifted activation after the change shipped.

  • Pain validated across 10+ practitioner interviews and founder communities.
  • V1 is PostHog-first and outcome-sharp — not a general analytics co-pilot.
  • Designed for the person who owns activation personally, not a growth org.

Activation lift

Mission · idk

What we optimize for

Evidence over intuition

Prescriptions come from retention gaps and drop paths, not founder vibes.

Smallest useful test

Every diagnosis ends in a confirmatory experiment and real people to ask.

Founder-speed clarity

Sharp outcomes in hours — not another dashboard that needs a data team.

Design partners

Bring your PostHog. Leave with a prescription.

MVP is shipping now. We’re onboarding a small set of early-stage B2B SaaS founders who own activation and want diagnosis over dashboards. Prefer the product app? Open the app.
