About Rezoki

We believe no SaaS company should lose revenue to failed payments.

Our Mission

Eliminate involuntary churn for every subscription business on the planet.

Failed payments are the single most fixable cause of lost revenue in SaaS. Yet most companies treat them as an afterthought. We're here to change that.

The Problem

The Silent Revenue Killer

$129B

Lost annually to failed payments globally

20-40%

Of SaaS churn is involuntary

85%

Of dunning emails go unopened

To set up Rezoki and start recovering

Every year, $129 billion in subscription revenue is lost to failed payments globally. For the average SaaS company, that translates to 9-14% of MRR silently disappearing — not because customers chose to leave, but because their credit card expired, their bank flagged a charge, or they simply didn't have funds on the day your renewal hit.

Most companies respond with a single generic email and a few payment retries. Open rates hover around 12%. The vast majority of these customers never see the notification, never update their card, and quietly churn. They wanted your product. You wanted their money. Nobody wins.

The Solution

AI-Powered Recovery That Runs 24/7

Rezoki is an AI agent that automatically recovers failed payments for SaaS companies. When a subscription charge fails, Rezoki detects it instantly and launches a multi-channel recovery sequence: smart payment retries, personalized email outreach, and AI-powered voice calls.

The AI voice calls are what set Rezoki apart. When 85% of your dunning emails go unread, a phone call reaches customers that email simply can't. The AI agent speaks naturally, references the customer's name and plan, explains the situation, and provides a direct link to update their payment method. It's personal, effective, and available around the clock.

The Team

Built by People Who Get It

Rezoki is built by engineers who have experienced the pain of lost revenue at scale. We've watched MRR leak through failed payments at companies we've built and worked at. We built Rezoki because we couldn't find a tool that combined intelligent retries, great email, and the one thing nobody else was doing — actually calling the customer.
