Why this score? ↓

What we have established three decisions, kept apart

  1. 1 Identity verified Not recorded

    No person- or entity-level identity check is on record for this company. A name match is not one.

  2. 2 Evidence sufficient to publish Not yet

    The inclusion bar: two or more independent sourced evidence families. This profile is reachable but not in the ranked index. It is a statement about how much evidence we hold, and about nothing else.

  3. 3 Fit for a seed/Series-A sourcing buyer Not established

    We have not established fit. That is not a soft no and not a soft yes — it is unknown, and it is never counted as a qualified prospect.

Unproven ≠ false — it means the deadline or the evidence hasn't arrived. Nothing here is editorial: every count is a ledger row you can open on the Proof page.
