Valkyrie

Valkyrie is software that recovers revenue lost to failed Stripe payments in subscription businesses. It connects to Stripe via OAuth. Valkyrie analyzes failed payments, separating those retried by Stripe from those recoverable through customer outreach. The platform sends branded emails to customers with failed payments, optimizing timing for better response rates. A dashboard tracks all failed payments, showing what Stripe recovered and what remains recoverable. Valkyrie provides a full audit trail of recovery activities and recaptured revenue beyond Stripe's efforts. Card data stays on Stripe's servers, inaccessible to Valkyrie.
