The quick answer: The Lean Canvas
A one-page business model with emphasis on problems, solutions, and key metrics. Nine sections: (1) Problem: what are your customers' main pain points? (2) Customer segments: who feels these problems most? (3) Unique value proposition: why are you better? (4) Solution: what's your approach? (5) Channels: how do customers find you? (6) Revenue streams: how do you monetize? (7) Cost structure: what are your biggest costs? (8) Key metrics: what indicates progress? (9) Unfair advantage: what's hard to replicate? Fill it out, identify your riskiest assumption, then design a test to validate it. Iterate based on results.
Why Running Lean matters for growth marketers
The Lean Canvas strips the Business Model Canvas down to what early-stage companies actually need to test. It forces you to identify your riskiest assumption upfront, usually the problem you think you're solving, and run experiments to validate it before wasting time on features nobody needs.
The top lessons growth marketers take from it
- 1
Your riskiest assumption is your first test target
Most teams test random features. Instead, identify the one assumption that would kill your company if wrong (usually the problem, not the solution), and run an experiment specifically designed to validate or disprove it. This prevents you from optimizing the wrong thing.

Problem-solution fit comes before product-market fit
You can have a polished product for a problem that doesn't exist or that nobody cares about enough to pay. Maurya's framework pushes you to validate the problem with real potential customers before building the solution.

Systematic experimentation beats intuition
The book gives you a structured process for running experiments: map your hypothesis on the Lean Canvas, define the riskiest assumption, design a cheap experiment to test it, measure, then iterate. This beats the ad-hoc "let's try something and see what happens" approach.
When to read it
When you need to quickly map and test early business hypotheses, especially before you've committed to building anything substantial.
