PostHog integration

Find the product journeys that finish—and the revenue they can prove.

Grow or Die reads product behavior from your PostHog Cloud project, recomputes saved funnels for the selected period, and keeps funnel completion separate from revenue attribution.

Connect PostHog

What it reads

Domain-scoped product evidence

  • Visitors, sessions, daily activity, realtime users, pages, and top events.
  • UTM campaign, referrer, country, device, and field-coverage diagnostics.
  • Up to six saved funnels, their steps, entrants, completions, and bounded completer evidence.

What it does not do

Your PostHog project stays unchanged

  • No writing events, editing insights, changing funnels, or modifying project settings.
  • No public project token; reports require a personal API key with query access.
  • No raw completing-person IDs persisted or returned to the browser.

How to connect

Use project query access

  1. Open the PostHog US or EU Cloud project that records the connected website.
  2. Copy its numeric Project ID.
  3. Create a personal API key with project query read access.
  4. Choose the cloud region, enter both values, and run Connect and test.

The key is encrypted at rest. Grow or Die runs domain-scoped HogQL queries and removes the connection when you disconnect it.

What it unlocks

A trustworthy visitor denominator and funnel comparison

PostHog can supply visitors, product behavior, acquisition context, and a highest-completion saved funnel among the funnels actually imported. Linked account revenue appears only when a completing identity resolves through a server-created identity link to the same account as an observed payment.

Current limits

Completion is not causation

A winner requires at least 20 entrants and complete, non-sampled results. Bounded, unresolved, or conflicting actor evidence stays partial or unavailable. The same paying account can complete multiple funnels, so linked revenue rows must never be summed into site revenue.
