# Lean Analytics

Decide which numbers actually tell you how the business is doing

## What this does

Your dashboard is full of numbers and none of them tell you whether things are going well. This helps you choose the few metrics that matter for your kind of business and your current stage, and spot the ones that only look good. Useful when someone asks what you should be tracking, or when a dashboard needs a clear-out.

### Top 3 things it does for you

- Pick the one metric that matters right now
- Strip vanity metrics out of a dashboard
- Set targets and baselines for a new feature

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Lean Analytics

Based on Croll and Yoskovitz's "Lean Analytics", this skill helps you choose and audit the metrics a startup or a feature is measured by.

It works through the difference between good metrics and vanity metrics, the One Metric That Matters, which metrics fit which business model, the five startup stages, and benchmarks to judge your numbers against. You can use it to pick metrics from scratch, to instrument a product, to set targets and baselines, or to go through an existing dashboard and see what is really being reported.

It also comes up when the question is about KPIs, a north star metric, churn, DAU and MAU, or measuring product-market fit. For the build-measure-learn loop see lean-startup; for activation and retention problems see improve-retention.

## Questions

### Is Lean Analytics safe to install?

AIR scanned this exact version of Lean Analytics and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 326b3801223a, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/lean-analytics.

### How do I install Lean Analytics?

Open https://airmarket.ai/app/lean-analytics on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/wondelai/skills/tree/326b3801223ad277ae7082ff85435ba1d36e1903/lean-analytics. Install from that link, not the branch.
