Buying Signals & Intent
Buying signal platforms watch public and first-party events, job changes, hiring, funding, technology adoption, community activity, and product usage, then surface the accounts that just became worth contacting.
Static lists decay the moment they are built, so the sharpest small teams stopped prospecting by firmographics and started prospecting by events. The tools here differ mainly in which signal they own: a champion changing jobs, a competitor's tag appearing on a site, a Slack community post, or a free-trial user hitting an activation milestone. What they share is the job of turning a raw event into a scored, routed, actionable task rather than another dashboard.
