A glimpse inside

Illustration for Lean Analytics
One Metric That Matters

A central concept in Lean Analytics is the idea of focusing on a single, most important metric at any given stage of your business. Rather than drowning in data, the book urges founders to identify the number that will drive their next decision or milestone. This focus helps teams avoid analysis paralysis and ensures that everyone is aligned on what needs to improve right now. As your business evolves, so does the metric you track, ensuring that your attention is always on what moves the needle.

Stages of Startup Growth

Lean Analytics breaks down the startup journey into distinct stages: Empathy, Stickiness, Virality, Revenue, and Scale. Each stage has its own goals and key metrics. For example, in the Empathy stage, you’re validating that a real problem exists, while at Scale, you’re optimizing for efficiency and growth. By understanding which stage you’re in, you can avoid premature scaling and focus your resources on solving the right problems at the right time.
