The new entrepreneurship era is all about customers and their problems. The number one reason that startups fail is lack of customers, not product development failure. The Lean Startup is an approach that acknowledges this and is a collection of techniques built for validating learning through fast iteration, particularly the "Build > Measure > Learn" cycle.
This is not a group to promote general entrepreneurship, it is a focused group for people who are introducing new products and services into the market, particularly in the technology sector. If you are a high-tech entrepreneur who strives to discover customers and build the products that they want, then this group is for you.
