Churn Solution is a subscription retention and revenue recovery platform for B2C subscription businesses on Stripe. It automates three things that usually leak revenue silently: cancellation saves, failed payment recovery (smart retries + dunning email/SMS), and win-back campaigns for subscribers who already left. Built for companies from $5k to $5m in MRR. No enterprise contract, no engineering build. Customers have reported a 45% reduction in churn and a 31% increase in LTV.
