Growth
Frameworks are cheap. These notes are about turning one of them into a measured experiment, with the reports to prove it worked.
Growth articles start from a model (AARRR, a funnel, a retention curve) and end with a concrete experiment and the report that judges it. We write them for marketers and product managers who have more ideas than engineering time and need a way to rank them.
