| Description | Cust is an AI agent for B2B customer success and retention teams that connects to your CRM, email, calendar, and support/product data to continuously deep-research your entire book of business, flagging silent-churn risks and expansion opportunities the way a dedicated account manager would. It prioritizes your portfolio, explains the reasoning behind each account score, and drafts multi-step actions -- QBR briefs, churn forecasts, ROI calculations, and renewal proposals -- that you run in one click. Unlike legacy CSPs like Gainsight, Totango, or ChurnZero, it goes live the same day with no rigid automations, templates, or months-long implementation. | Cold outreach platform with unlimited email accounts, inbox warmup, and deliverability tools that keep campaigns landing in the primary inbox. Built for agencies running outreach as a service and lead generation. |
