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 Yes

    The inclusion bar: two or more independent sourced evidence families. This profile is published and listed. 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.

    UNKNOWN (not a soft no, never counted as qualified). Blocker: No source states a band-bearing stage for any financing event we hold.

    Venture backing: not found · Stage band: UNKNOWN — No source states a band-bearing stage for any financing event we hold.

    What would overturn this:

    Assessed 2026-10-24 for seed/Series-A sourcing.

Composite signal v0 insufficient evidence — 1 of 5 components

Five evidence lanes (activity, capital, infra, hiring, ecosystem) as within-cohort percentiles, combined with evidence-breadth weights over the 60-company baseline cohort. The ± band widens with missing lanes — it measures what the score stands on. Scores publish at 2+ evidence lanes; this company's tape carries 1 (0 signals/60d), so no number is claimed.

The skeptic's read what this company has said, judged against what happened

1 claims on record 0 verified 1 contradicted 0 still unproven

Sharpest miss on record: “OpenAI will acquire Windsurf for approximately $3 billion.” — No record of OpenAI acquiring a company named Windsurf for about $3 billion, and no such acquisition has been announced or reported in any reputable source.

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.
