AI Venture Index (2 matching, ranked by VentureSignal)

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.
