Timing outreach to real-world buying signals instead of blasting a static list.
Signal-based selling (or signal-based targeting) means reaching out the moment an account shows a buying signal: a funding round, a wave of hiring, a tech change, a website redesign - rather than blasting a static list. Relevance is highest the week a signal fires and decays fast, so speed is the advantage. The same engine surfaces both new-business and expansion timing.
