Customer retention software for SaaS

Stop losing customers to silent churn

Your customers aren't leaving because they hate your product. They're leaving because you charged them full price for a month they barely showed up. RetAIn fixes that.

How RetAIn works

Three steps. No billing migration. No rebuilding anything.

01

Set your base fee

Your revenue floor, always guaranteed. It covers what it costs to run their account — servers, support, nothing more.

02

RetAIn tracks usage

Simple REST API integration. A few lines of code and you're live. Most teams ship it in a weekend.

03

Bill matches reality

Base fee + actual usage, capped at your full price. Heavy users pay full. Light users pay less. Nobody has a reason to cancel.

The old way vs RetAIn

Without RetAIn

  • Full price every month regardless of usage
  • Slow months breed quiet resentment
  • No warning before cancellations
  • Lost forever over a fixable billing problem

With RetAIn

  • Bill reflects actual usage automatically
  • Slow months = smaller bill, no resentment
  • At-risk accounts flagged early
  • Net revenue retention improves
