The Lean Startup by Eric Ries

Added Aug 18, 2026, 5:41 PM

The Lean Startup by Eric Ries presents a practical approach to building startups under uncertainty. Its core idea is to avoid spending too much time and money developing a product before testing whether customers actually want it. The book introduces concepts such as Build–Measure–Learn, Minimum Viable Product (MVP), and validated learning. Startup founders are encouraged to test assumptions quickly, gather customer feedback, and either improve their approach or pivot when evidence suggests a different direction. It may be especially useful for founders because it offers a framework for reducing wasted effort, learning from customers early, and making decisions based on evidence rather than assumptions.
