We improve retention curves.

Here is what that means for your business.

A more sustainable business

Profitable from order two

Most brands do not cover their acquisition cost until month four or later. Moving that to order two raises your ceiling and makes growth hold.Move profitability closer to order two, raise your ceiling, and make growth hold.

A more defensible valuation

LTV:CAC above 3× on margin

The ratio acquirers look at before revenue. Above 3× means the business compounds. Below it means it leaks. Most brands do not know which side they are on.Above 3× means the business compounds. Below it means it leaks. Most brands do not know which side they are on.

A better exit when the time comes

Month three — the retention fork

Where subscribers decide whether your product is a habit or a mistake. The brands that win that window build the curves acquirers actually pay for.Month three is where subscribers decide whether your product is a habit or a mistake.

We start where your agency stops.

We move one-time purchases to subscribers. We get subscribers to stay longer.

CAC LTV

CAC:LTV

Every acquisition spend either builds a business or funds a leak. We diagnose where the ratio is broken and install the system that fixes it permanently.

Your agency tracks save rate. We track LTV per subscriber.

Active Subscribers

Not your total subscriber count. The percentage actively compounding — paying, retaining, increasing their value to the business month on month.

Your agency counts subscribers. We count the ones compounding.

Retention Curves

Your subscribers are making a decision about your brand in the first 90 days. Most leave before month four. We install the system that bends that curve.

Your agency optimises flows. We bend the month-three curve.
