“Lean Startup is not a religion,” said Eric Ries, the 37 year-old author of The Lean Startup (2011), which is the handbook for what has become a cult-like movement embraced by entrepreneurs and innovators worldwide.
The core philosophy of the book – and of its practitioners – is to test ideas early and often by getting feedback from potential customers. Before investing very much time and money into a product, the idea is to quickly create an MVP (minimal viable product) and put it in front of potential consumers. This avoids wasting time and money developing products that people may not want.
