The document discusses getting lean at startups. It recommends having a small "Goldilocks" team that works well together. The team should be fast, focused, and make small bets to test ideas quickly through a build-measure-learn process. To get lean, the author recommends reorganizing teams around product, reducing meetings in favor of continuous communication, and investing resources in what works based on measuring results. The overall message is that being lean is about moving quickly through testing ideas rather than being cheap.
