Lean startup

Lean startup is a method for developing businesses and products first proposed in 2008 by Eric Ries. Based on his previous experience working in several U.S. startups, Ries claims that startups can shorten their product development cycles by adopting a combination of business-hypothesis-driven experimentation, iterative product releases, and what he calls validated learning. Ries' overall claim is that if startups invest their time into iteratively building products or services to meet the needs of early customers, they can reduce the market risks and sidestep the need for large amounts of initial project funding and expensive product launches and failures.

Originally developed in 2008 by Ries with high-tech companies in mind, the lean startup philosophy has since been expanded to apply to any individual, team, or company looking to introduce new products or services into the market. Today, the lean startup's popularity has grown outside of its Silicon Valley birthplace and has spread throughout the world, in large part due to the success of Ries' bestselling book, The Lean Startup: How Today's Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses.
