Signals are the trigger layer: the thing that starts an agent's loop rather than something it calls halfway through. Coverage here is decent and the access gate is the harder problem.
Tools that try to answer "who is about to buy, and how do you know." The category splits cleanly into two eras: the legacy enterprise intent-data incumbents (6sense, Demandbase, Bombora, HG Insights) sold on annual contracts with no self-serve path, and a newer wave of visitor-ID/job-change/ API-first tools (RB2B, Warmly, Crustdata, TheirStack, PredictLeads) built for solo operators with free tiers and documented MCP servers.
