Every year we take the opportunity to run a comprehensive survey of professionals at SaaS companies ranging from early startups to established businesses with over $100M in revenue. Our aim is to better understand the key performance indicators used by SaaS companies to run their business. For the 2016 SaaS Metrics survey report, we have added several questions based on the comments and responses over the years. New topics covered this year include company spending on customer retention and the definition/measurement of customer health.
