Scores existing customers on their likelihood to expand so the team can prioritize cross-sell and upsell. Combines a 0-100 readiness score across seven weighted factors (land-deal profile, firmographics, buying-group depth, post-land engagement, expansion signals, whitespace fit, and risk) with per-account detail: score breakdown, recommended plays, estimated value, key evidence, top risk, and a full narrative — plus sort, filter, and CSV export.
