Signal-based selling is outbound built around a real reason to reach out, a buying signal, instead of a static list of job titles.
The bet is timing. A prospect who just raised, switched tools, or hired for a gap is far likelier to answer than the same person contacted at random. The mistake is treating signal-based as a data badge while still blasting the whole list the same week. The signal only helps if the message and the timing actually change because of it. The full worldview, and how a two-person team runs it, is in our guide to signal-based selling.
