# Teardown — activation funnel on a SYNTHETIC event stream

> Generated data, not usage data. Three queries against one extract; the maturity gate and the censoring rule that stop recent cohorts reading as a decline.

# An activation funnel, on data we made up

Generated event stream, seed 20260904 · synthetic clock · SYNTHETIC — NOT USAGE DATA

The data on this dashboard is generated. It is not usage data from vibedasher or from any real product, and no number on it means anything about anybody. It is here for the shape of the analysis.

SYNTHETIC — the event stream is generated, seed 20260904, and it is not usage data from vibedasher or any real product. Three queries over a 141 KB extract. It is here for the censoring rule; the numbers mean nothing.

![A dark dashboard titled "Activation funnel on a synthetic event stream", flagged "synthetic — not usage data". Five step cards count distinct users: signed up 2,000, activated 1,164 (58.2%), built first dashboard 848, published 503, shared 225. A "what the data says" panel of three findings sits above two bar charts — the nested funnel itself, and the drop at each hand-off, the largest being 836 users lost between signup and activation.](https://vibedasher.com/showcase/shots/activation-funnel-synthetic-event-stream.webp)

## The question it answers

How do you build a funnel-and-cohort view when the newest signups have had less time to convert than the oldest?

## The data, and over what period

A generated event stream. The numbers mean nothing about anybody; the analysis does.

## How it gets its rows

Three queries, in your browser, with no key.

## What comes back

Three result sets from one 141 KB extract.

## What was hard

Censoring. Cohorts are measured over a common matured window, not over whatever time each has had — otherwise last month’s cohort reads as converting worse than one from a year ago, and the decline you see is the clock.

## What happened after the build

Frozen. Generated once, 2026-08-31.

The live dashboard loads from the viewer host. Nothing is fetched from it until you ask, so this page does not touch that origin unless you want it to.
