33 / Growth evidence
Measure the path to adoption—not just attention.
This privacy-minimised funnel records first-party website actions and programme outcomes. Off-site impressions remain outside the count until they are imported from the platform that produced them.
01 / Live funnel
Website visit → demo → receipt → developer outcome.
UTM source, medium and campaign labels can be recorded without building behavioural profiles. IP addresses, wallet addresses and receipt contents are not stored in this funnel.

02 / Attribution format
Every outreach link gets a transparent campaign label.

The first-party endpoint records the campaign labels and page path. X or YouTube impressions still have to come from those platforms' own analytics.
03 / Decision rule
Optimise for reproducible use.
- Repeat the content that produces demo starts and public receipts, not only impressions.
- Do not count applications as integrations or publications as independent reviews.
- Publish unchanged zeros and failed experiments.
- Keep market volume and product adoption on separate scorecards.
