Retainer is a Whop app for community owners. When a member's renewal fails, Whop retries for 5 days and then cancels — nobody messages the member. Retainer DMs them from your own support chat the minute the charge fails, follows up twice, stops the second they pay, and counts only the revenue that actually came back. Read-only access, free plan, 30-second install. Free tools: churn calculator, win-back DM templates.
Hi Product Hunt — Lucas here, maker of Retainer.
I built this after checking 33 Whop product pages one by one and realising that owners can't see their failed-renewal line. When a renewal fails on Whop (expired card, bank block, limit), Whop emails the member and retries for 5 days, then cancels the membership. Nobody messages the member, and the dashboard never shows the loss. In a normal month that's 3–5% of charges — on a weekly plan, four times more.
Retainer listens for the failed-payment event, DMs the member from the owner's own support chat within minutes, follows up twice, stops the second they pay, and counts only the revenue that actually came back. It also handles scheduled cancellations and members who went quiet.
It's read-only on your data, installs in 30 seconds, and the failed-payment sequence is on the free plan. Recover is $0/month + 20% of what comes back.
Free tools if you don't want the app: the churn calculator (runs in your browser) and the win-back DM templates on the blog.
Ask me anything about the 5-day retry window, weekly billing, or what the "members joined" number on a whop page actually means — I have the data.
