A full run over this vertical delivers an estimated ≈48,412 eligible agencies, each with a complete 23-signal extraction — the IAB Advertising category spans 719,358 domains, and we screen all of them. The measured basis for that estimate: a 10,000-domain random calibration sample, which alone surfaced 673 eligible agencies. The 10 cases below are format showcase only.
Every case on this page is drawn from a real screening run. Because the companies shown are privately held businesses, we follow standard confidentiality practice on public pages: quotes are paraphrased, and names, clients and identifying details are replaced (e.g. “ACME 1 Inc.”). The published text is therefore intentionally not traceable to the companies — including through a web search — which protects them without diminishing the underlying data. Pilot and client deliverables contain the original verbatim quotes with source URLs, so every claim can be verified directly. Start with a free pilot →
Basis of the estimate: a 10,000-domain random calibration sample measured a 6.73% eligibility rate (673 eligible agencies in the sample). Applied to all 719,358 domains, that projects to ≈48,412 candidates — every one delivered with the full signal transcript you see showcased below.
That is the deliverable of a full run: an estimated ≈48,412 eligible agencies with all 23 signals each. The funnel below shows how the estimate was measured — a 10,000-domain random calibration sample (1.4% of the vertical) processed end to end. Every rate in the funnel is measured, then extrapolated to the full 719K.
