filings, certificate transparency, podcast transcripts, GitHub activity, and federal
records — every number tracing back to the observation behind it.
⚡ How the signal readsone worked instance, live from the ledger — not a mockup
83 days before Modal
announced its round, we logged a new product-shaped subdomain on its own domain — from public certificate-transparency records:
api.modal.com
logged 2026-07-23 · 83d early
certificate dated 2026-07-19
Then the round became public: Series D · $750M
announced 2026-10-14 · now VS 88.3
Counted from the day we logged the signal, not the date on the document — the
same test the lead-time ledger holds itself to.
This is advance notice on a later round of a company already in the
index — not a first discovery, and not a seed or Series A case.
Whether the same signal finds companies at that stage is not yet established.
Scored ≥70 with no funding round in our data — strong outside signal where our
own financing coverage is thin. Not a claim that these companies are unfunded. Signal feed →

This is a count of companies whose evidence is sufficient to publish a
profile — not a list of qualified leads. Whether a company is a fit for a
seed/Series-A sourcing buyer is a separate decision, assessed company by company and
counted separately: qualified prospects →
Each score is a cross-signal composite. The strip under it shows the three
families it’s built from — funding, package
adoption, and developer momentum — lit
when present, and how many of the three back the score. Fewer signals means
a coverage-discounted score, not a missing one.
