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.

Narrative vs. reality No SEC filing found for this round

Reported narrative · Tier 2
Undisclosed
announced 2026-04-27 · source ↗
Filed reality · Tier 0 · SEC
No SEC Form D on record.

An evidence gap, not proof of falsity: Form D is not always required (foreign offerings, certain exemptions) or may not be filed yet.

Financing events four different events, four different dates

A first sale, a filing, an amendment and a public announcement are not the same event, and one date may not stand in for another. Where the latest financing date cannot be established from what we hold, this says unknown rather than substituting a date we do have.
