Signal Layer Stack

Deal Intelligence tools each capture one layer of evidence: conversation capture, relationship scoring, stakeholder mapping, ecosystem overlap, and post-sale health. The Signal Layer Stack framework says agencies should map which layer each tool covers before recommending anything, because two tools that both claim 'deal risk' often read different inputs and produce conflicting verdicts. A practical test: ask what data source feeds the score. Ebsta scores relationships from calls, emails, and meetings synced to Salesforce or HubSpot. Crossbeam reads CRM account overlaps across partner ecosystems to surface warm pipeline. Rimplo pulls CRM, billing, support, and product data to flag churn and expansion. Stack them and a client gets one narrative; overlap them and the client gets three dashboards arguing. For agencies on retainer, the deliverable is the synthesis, not the seat license. Forrester's September 2026 finding that private AI deployments outperform shared public models reinforces the point: the differentiated layer is the client's own combined signal, not any single vendor's model.
