Most startups' growth stalls because they pour users into a leaky bucket.

That is why you should look at AARRR not as a funnel but as loops.

AARRR is one of the most popular frameworks in product-led growth.

It’s also one of the most misunderstood.

Many draw it as a top-down funnel. It’s not. It’s loops.

Why does it matter?

When you see a top-down funnel, you optimize from the top down.

Funnel leads you to pour more users in at the top.

When growth stalls, you focus on pouring even more users.

But acquisition without retention is a leaky bucket.

You pour users in. They go right out.

McClure’s original showed the truth:

• Referrals loop back to acquisition.

• Retained users come back and generate more revenue.

• Revenue funds more acquisition.

(See the original image in the playbook)

These are loops, not funnel.

Somewhere along the way, people redrew it as a top-down funnel.

No loops. No feedback.

Lose the loops, lose the point.

The real way to use AARRR:

Measure all five. Find the weakest. Fix it first. Then look for loops.

That’s how sustainable growth works.
