Cohort Closer

This week's day-7 retention vs last week's, every Monday.

Data & ReportsProductivity

Once a week, Cohort Closer pings the room the day-7 retention of your newest cohort set against the one before it — the single number that says whether the product is sticking better or worse than last week. The ping carries this cohort's percentage, last cohort's, the gap between them, and an arrow for direction. No spreadsheet, no manual cut. You run your retention query on a weekly schedule and POST the two figures to a webhook URL. Anything that can send an HTTP request, webhook, or MCP call can deliver them: a scheduled SQL job, your analytics warehouse, an MCP-connected agent that computes the cohorts for you. Set the day and time once and the comparison shows up like clockwork. Operated by PingRoom.
