Earlier this week, we covered Blackbox, the young company responsible for creating The Startup Genome Report, an ongoing, collaborative R&D project designed to take a comprehensive dive into what makes Silicon Valley startups successful -- and not. (Read our initial coverage here.) On Tuesday, we covered the company's launch of what it calls the Startup Genome Compass, a benchmarking tool for startups that helps founders monitor their progress in different growth categories. Since then, more than 6,000 startups have signed up to use the Compass. Along with the diagnostic tool, Blackbox also released a new research report on the major causes of startup failure, including perhaps more significantly, the primary cause of startups kicking the bucket: Premature scaling. While this was touched on in our prior coverage, we thought it might be worth elaborating on their findings, including presenting a nifty infographic created by the team over at Visual.ly.
