Exeechain is a customer success platform for B2B SaaS companies that puts churn prediction, account health scoring and failed payment recovery in a single product. Each customer is scored from 0 to 100 every day, the signals driving that score are spelled out in plain English, and the rescue email is drafted from that account's own support tickets, NPS answers, usage and renewal date, then held for a human to approve. Data comes in from Stripe, Salesforce, HubSpot, Intercom, Zendesk, Mixpanel and Slack. A failed card triggers a dunning sequence that stops as soon as the payment goes through. Revenue forecasts are timed to actual renewal dates, QBRs are written from the account's data, and an AI Copilot answers questions about any customer from that workspace's records. The free plan is the full product on a realistic sample dataset. Paid plans start at $299 per month for 150 customers, then $999, $2,999 and Enterprise from $5,900. No implementation fee, month to month.
