The tracking metric you've never heard of that 4x'd a $750M business 📈

Duolingo was stuck in 2018.

Yes, $750M in revenue & 40 million+ daily users…

But growth?

Flatlining.

Hundreds of tests running… Nothing moving the needle.

They were trapped optimizing metrics everyone tracks: conversion rates, retention rates, acquisition costs.

Then they used a framework that flips traditional tracking on its head…

…exposing the ONE metric that mattered most...

…buried in every DTC subscription brand's biggest blind spot.

When they tested it against everything else — new user acquisition, reactivation campaigns, onboarding flows — this one metric had 10x more impact than all of them.

The result?

4x growth.

Not from better ads. Not from new traffic sources. Not from a rebrand.

From tracking one transition that 99% of subscription brands completely ignore.
