This document discusses incubator 2.0 and lessons learned from previous incubators. It summarizes that incubators should focus on making many small investments and expecting a high failure rate (60-80%). Successful incubators provide mentoring support and focus on getting startups to build functional prototypes, test customer usage, and quickly iterate based on feedback. The goal is to identify the top 20% of startups that show traction after 6-12 months and double down the investment in those companies.
