Signal stacking tracks buying-intent clues as they build up in an account. One job post only hints at interest; add a fresh funding round and a tech-stack change and you have proof and three angles for tailored outreach.

It’s detective work: a single fingerprint intrigues, but fingerprints, shoe-prints, and CCTV together make the pursuit worth your time.
