This document discusses the concept of pivoting in startups. It summarizes the founder's experience with LivingSocial over many years, during which they tried several different business ideas before finding product-market fit. Some of their early ideas like social application consulting and a visual bookshelf site did not prove scalable. Through persistence and many pivots, they eventually succeeded with LivingSocial's daily deals platform in 2009. The founder emphasizes the importance of measuring everything, learning quickly, and iterating until finding a successful product.
