Signal360 monitors predictive signals (funding, leadership changes, tech adoption) and demand-capture signals (website visits, pricing page views, competitor searches) across the complete buying journey. The platform automatically identifies all buying committee members and uses GTMCanvas to build signal-triggered automated workflows, aligning Marketing, Sales, and RevOps around the same intelligence.
