Retention-as-a-Service for micro-SaaS

Stop losing revenue to preventable churn

Connect Stripe. We recover failed payments, deflect cancellations, and you only pay when we save you money.

Free audit. No credit card required. Takes 2 minutes.

How It Works

Three steps to stop the leak

Step 01

Connect Stripe

One-click OAuth connection. We get read access to your billing data. No code changes needed.

Step 02

We Detect & Act

Our engine analyzes payment failures, at-risk customers, and cancellation patterns in real-time.

Step 03

You Keep Revenue

Failed payments get recovered. Cancellations get deflected. You see exactly what was saved.

What We Handle

Two engines, one goal: keep your revenue

Smart Dunning

Intelligent payment retry logic that waits for the right moment. Paired with a warm, branded email sequence that gets cards updated without annoying your customers.

  • Decline-code aware retry scheduling
  • 3-step email sequence (gentle, urgent, final)
  • Card expiry pre-dunning prevention
  • Automatic recovery tracking

Cancel Deflection

A lightweight widget that intercepts cancel clicks with smart, reason-based retention offers. No more silent churn.

  • Customizable cancellation survey
  • Dynamic offers based on churn reason
  • Discounts, pauses, and downgrades
  • 30-day durability verification
Pricing
