Evidence sources

Different sources, one evidence graph.

Connector breadth is not the product. Each source is useful only when it can reduce a defined evidence gap against the Current Question.

Human and research evidence

Public web research, People, interviews, manual evidence, Notion, Google Docs, and explicit active-tab browser capture preserve source provenance and founder review.

Post-launch evidence

PostHog, Amplitude, Stripe, Paddle, Dodo, GA4, and Google Search Console can contribute behavioral, acquisition, and commercial evidence through provider-specific authorization. Private Google sources require delegated OAuth and fail closed when it is not enabled.
