How Growth Models Evolved

Growth models don't replace each other. They emerge when previous bottlenecks stop working.

The Five Growth Models

Model
Primary Question
What It Assumes
Bottleneck
SLG

Sales-Led Growth

How do we sell this?

Message is clear

Speed & scalability

PLG

Product-Led Growth

How do users adopt this?

Value is obvious

Message discovery at scale

MLG

Marketing-Led Growth

How do we tell the story?

Messaging works

Learning resets per campaign

Perf

Performance-Led Growth

How do we scale efficiently?

Right message exists

Creative fatigue & message clarity

CLG

Creative-Led Growth

What message actually works?

Message is discovered

Zero Bottleneck

The Shared Blind Spot

All models assume the message is already known.

They optimize distribution, not discovery.

Why CLG Had to Exist

Creation became commoditized

AI made output infinite. Clarity stayed scarce.

Platforms optimized for speed

Freshness + relevance > spend. Slow cycles lose.

Buyers stopped trusting hype

Logic, proof, resonance win. Not volume.

The hardest problem is no longer distribution. It's message discovery.

Where CLG Sits

CLG is the decision layer. Marketing packages it. Performance distributes it.

1Decision Layer

Creative-Led Growth

Decision — What belief to test

2Narrative Layer

Marketing-Led Growth

Narrative — Campaigns & launches

3Distribution Layer

Performance-Led Growth

Distribution — Spend & optimization

CLG decides what to say. MLG packages it. Performance distributes it.

Other models optimize around a message.

CLG discovers and validates the message.

Key Takeaway

CLG sits above other growth models as the 'Decision' layer. While others assume the message is known, CLG exists to discover and validate it.
