Built for SaaS founders who don't have time to babysit dunning flows.
Three perfectly-timed reminders before the card expires. Optimized for the highest update rate.
Sent from your domain with one-click update links. Customers do nothing more than click and confirm.
Daily 08:00 UTC sync plus on-demand refreshes. You'll see expiring cards the moment they appear.
We read your subscriptions and card metadata — we never charge cards, refund money, or modify subscriptions.
Track update rate, MRR saved, and which intervals work best. Optimize the cadence over time.
Smart scheduling that maximizes successful charges without spamming customers. Plays nice with Stripe's retry logic.
No re-platforming. No webhook plumbing. Just better timing on the emails Stripe doesn't send.
Stripe Connect OAuth — read access. We never see card numbers or charge details.
Each sync classifies every active subscription into 30, 14, and 7-day expiry windows.
Friendly nudge from your domain — 68% of customers update before renewal even runs.
Checking expiring cards…
Most dunning tools show up after the charge has already bounced. By then the customer is annoyed, the email goes to spam, and your MRR is already gone.

“We were silently losing around $400 a month to expired cards. CardHawk caught 6 cards in the first scan. Four customers updated within 48 hours. Pays for itself every month.”
