What is the difference between Lean Canvas and Business Model Canvas?

Lean Canvas replaces four blocks from the Business Model Canvas (Key Partners, Key Activities, Key Resources, Customer Relationships) with Problem, Solution, Key Metrics, and Unfair Advantage. The result is more focused on early-stage startup risk.

Which block should I fill in first?

Start with Problem and Customer Segments. Everything else is downstream of correctly identifying who you are serving and what pain you are removing.

How long should it take to fill out a Lean Canvas?

A first draft should take 15–20 minutes. The point is to surface assumptions quickly, not to write a polished document.

How often should I revise the canvas?

Treat the canvas as a living artifact. Revise it whenever you learn something material from a customer interview, an experiment, or a metric — typically every one to two weeks in the early stage.

What counts as an Unfair Advantage?

Something that genuinely cannot be easily copied or bought — insider information, personal authority, a community, a network effect, or an expert endorsement. Features and capital do not qualify.
