We believe the best products
are built by people who care deeply.
The moment a payment fails, that care deserves to show.
Every month, 5–9% of your MRR disappears in silence. Stripe retries the charge. But half those failures aren't payment problems — they're moments when your customer needed to hear from you.
DunnAI reads why each payment failed, and speaks to your customer in your voice. Automatically. At exactly the right moment.
Connect your Stripe account in 5 minutes.
No engineers. No code. No credit card.
Free until DunnAI recovers $49 for you.

What does 5–9% mean for you?
Enter your MRR to see what you might be losing.
*Based on industry data showing SaaS businesses lose 5–9% of MRR each month to failed payments (Stripe, ProfitWell). Monthly figures above reflect that estimate for your MRR. Actual results vary based on your decline patterns.
Your free diagnostic report is waiting.
At $10,000 MRR, you likely have 21+ failed payments in the last 90 days — worth $2,079+ in lost revenue. Connect Stripe to see the exact breakdown.

But here's the part Stripe doesn't tell you. ↓
Most of that lost revenue
isn't a payment problem.
It's a communication problem.
When a card expires, Stripe retries the charge.
Again. And again. And again.
It will never work. Because the card is gone.
Your customer needs to hear from you — not from Stripe — about their specific situation.
There are two kinds of failed payments.
Stripe can only fix one.
The customer has money coming. Retrying at the right moment works.
Banks lift restrictions automatically. Timing is everything.
DunnAI enhances Stripe's retry timing with decline-code intelligence.
That card is gone forever. No retry will ever succeed.
The customer got a new card. They need to update it.
The customer needs to call their bank or use a different card.
These customers need a message from you. In your voice. About their situation. That's what DunnAI does.
This is what Stripe cannot do.
This is why DunnAI exists.
One of these personas will communicate
with your customers on your behalf.
9 distinct recovery personas, each with a unique communication style. DunnAI selects and rotates through them to maximize recovery for your customers.
DunnAI rotates through personas and message variations to find what resonates best — and gets smarter with every recovery.
Set up in 5 minutes. No engineers needed.

Here's exactly what happens
when a payment fails.
DunnAI is a communication technology built on top of Stripe's infrastructure. Here's the full picture.
DunnAI sends a message to your customer — in your brand's voice, chosen from many variations for this exact failure type.
DunnAI retries the invoice at the optimal moment.
DunnAI connects with a restricted API key — cannot create charges, move funds, or access card details. Stripe executes all payments. You stay in full control.
Most tools give up after one retry.
DunnAI runs a full recovery sequence.
Instant detection
The moment Stripe reports a failure, DunnAI reads the decline code and decides the optimal recovery path.
Smart retry
DunnAI retries at the optimal window \u2014 typically 24 hours after a decline \u2014 maximizing the chance of success.
First outreach
A personalized email goes to your customer \u2014 written for the specific reason their payment failed.
Escalating follow-ups
Follow-ups increase in urgency but never in aggression. Day 3 is a firm reminder. Day 7 flags service interruption.
Payment collected. Customer retained.
Recovery rate depends on your decline patterns. Connect Stripe to see yours for free.
Your Stripe account is safe.
Here's why.
We know you're trusting us with access to your payment infrastructure. Here's exactly what that means — and doesn't mean.
We cannot see card numbers.
Stripe never exposes full card details through their API — to anyone. Not to DunnAI. Not to any third party. This is a technical guarantee built into Stripe’s architecture, not just our policy.
We cannot create new charges.
DunnAI can only retry invoices that have already failed. We cannot initiate new charges, change amounts, issue refunds, or move money between accounts. Ever.
You can revoke access in 30 seconds.
Delete the API key from your Stripe dashboard and DunnAI immediately loses all access. No need to contact us. No waiting period. You are always in control.

Stripe never exposes card numbers through their API — to any third party, including DunnAI. This is built into Stripe's architecture.
