Clean startup is a free, concise book on lean startup by Dr. Max Völkel.

After years of developing and refining, giving talks, seminars, and workshops, I can finally present this summary on Lean Startup methods, tools and insights.


Clean Startup explains how to systematically turn a number of ideas into a business model. The overall systematic business idea development-process (SBID) is described at the end. The core idea is to actively get and produce data, which lowers the risk of anything going wrong.
