We need to reengineer companies to focus on figuring out who the customer is, what's the market and what kind of product you should build.

Don’t be in a rush to get big. Be in a rush to have a great product.

The goal of a startup is to figure out the right thing to build-the thing customers want and will pay for-as quickly as possible. In other words, the Lean Startup is a new way of looking at the development of innovative new products that emphasizes fast iteration and customer insight, a huge vision, and great ambition, all at the same time.

Most phenomenal startup teams create businesses that ultimately fail. Why? They built something that nobody wanted.

When Steve Jobs and Steve Wozniak created Apple computer in a garage in Palo Alto, it heralded the beginning of the PC revolution that ultimately dealt a death-blow to dozens of older companies.

Every startup has a chance to change the world, by bringing not just a new product, but an entirely new institution into existence.

A solid process lays the foundation for a healthy culture, one where ideas are evaluated by merit and not by job title.
