nodunn is an autonomous recovery engine for SaaS on Stripe & Paddle. When recurring card charges fail, nodunn sends polite, founder-style emails with a 1-click passwordless update link—recovering up to 82% of lost subscription revenue on autopilot.
"Hey Product Hunt! 👋 I'm Sinan, founder of nodunn.
Did you know that nearly 48% of SaaS churn isn't because customers dislike your tool — but because of expired credit cards and bank limits?
We built nodunn to fix this quietly in the background. It sends gentle, founder-style recovery emails in your customer's native language with a 1-click passwordless card update link. Integrates with Stripe & Paddle in 2 minutes.
We'd love to hear your feedback!"
