Cust is an AI agent for customer retention that connects to your CRM, email, calendar and data sources to continuously deep-research every account, surface risk and expansion signals, prioritize the portfolio, and draft recommended actions you can run in one click (QBR briefs, churn forecasts, ROI calculations, renewal proposals, etc.); its AI provides reasoning for scores, adaptive goal-based flows instead of rigid automations, and personalized outreach at scale so teams can prevent silent churn, drive upgrades and expansion, and replace months-long implementations with instant, actionable intelligence.
