Every signal, one calm surface.

Built for the moment you stop guessing. Halcyon collects, models, and visualizes product behavior so the next decision is obvious.

Live funnels

Watch users move through onboarding in real time and pinpoint the exact step where momentum dies.

Retention cohorts

Auto-grouped cohorts reveal who comes back and why, with week-over-week curves that update themselves.

Anomaly alerts

A baseline model learns your rhythm and pings the right channel the moment a metric drifts off course.

Drag-build boards

Compose shareable dashboards from any event in seconds. No query language, no engineering ticket.

Privacy by default

PII is masked at ingest and every property is governed. Compliance reviews go from weeks to an afternoon.

Edge ingest

Events land in under 80ms from anywhere on earth, so dashboards reflect reality, not a five-minute-old snapshot.
