How do I keep customers from leaving?

Theanna measures every retention test you run, so you know what keeps customers paying.

02Sound familiar

Here's how most founders run it today.

And here's how you want to run it.

How you run it today-3
  1. -Customers cancel and you don't know why until the exit survey.
  2. -You send a monthly newsletter and hope people stay.
  3. -You notice churn after the revenue report, not before.
How you want to run it+3
  1. +You test re-engagement tactics and measure which ones reduce churn.
  2. +You catch at-risk customers before they cancel.
  3. +Your retention strategy is based on what works, not what feels proactive.
03What that leads to

You can't measure what you can't see.

Here's where it breaks down, and what Theanna does instead.

You find out about churn after it happens.

Theanna

Theanna watches engagement signals so you see at-risk customers early.

You send the same email to everyone.

Theanna

Test different re-engagement messages and see which ones bring people back.

You don't know what keeps your best customers.

Theanna

Theanna shows which features and touchpoints correlate with long retention.

You can't measure if a win-back campaign worked.

Theanna

Each test tracks reactivations and revenue recovered against a target.
