What we can enrich a lead with — and the receipt each fact must carry
Between the form and a personalized email or return visit, we can learn a lot
about a lead from outside sources. In Provenance, every enriched fact is gated like a claim:
it must come from a human-allow-listed source, carry a lawful basis, be fresh, and pass the
Enrichment Gate before it can appear in a message. This page catalogs the sources honestly —
what they give, what they cost, and the basis question. In the demo, sources are
used (simulated) unless marked live;
nothing here calls a paid API.
