Growth Hacking Frameworks

Growth hacking frameworks apply the AARRR funnel - Acquisition, Activation, Retention, Referral, Revenue - to find the one stage actually capping growth, instead of running marketing everywhere at once.

A funnel narrows through five stages, wide at acquisition and tapering down toward revenue at the bottom.

The AARRR funnel: five stages where growth typically leaks.

Reach for this when…

Marketing spend is scattered across channels with no clear read on what's working.
Users sign up but don't come back, and nobody has measured where they drop off.
A startup needs growth on a budget that doesn't stretch to a big campaign.

How to run it

Map the funnel: Acquisition, Activation, Retention, Referral, Revenue.
Measure the conversion rate at each stage to find the real bottleneck.
Generate a backlog of specific experiments aimed at that one stage.
Prioritise by Impact, Confidence, Ease and run the highest-scoring test first.
Measure the result, kill what didn't work, double down on what did.

A worked example

Situation. Fernanda Torres's small invoicing SaaS, Facturia, based in Guadalajara, Mexico, had healthy free-trial signups but the team kept spending on ads to bring in more.

Applied. She mapped the funnel properly and found the real leak was Activation - most trials never sent a single invoice - so the team built an in-app setup wizard and a ready-made invoice template instead of buying more clicks.

Result. Trial-to-first-invoice jumped, the ad budget got cut rather than increased, and the saved spend went into referral incentives instead.

Ledgerly's real leak was Activation, not Acquisition, once the funnel was measured.

The catch

"Growth hacking" gets used as a synonym for cheap marketing tricks, but the framework only earns that name if you measure the funnel first - guessing which stage is broken wastes the same budget as scattergun marketing. It also needs a live product with real usage data, so it fits an existing user base far better than a pre-launch idea. A fast-experiment culture can also trade short-term metric wins for long-term brand damage if nobody's watching that trade-off.

If you can't say which funnel stage you're fixing this month, you're not growth hacking, you're just marketing faster.
