Actually, I don't get why analytics should be SaaS. The detailed history of all user interactions with your product since launch day is one of your company's _crown jewels_, far more than your payroll data, or even your ticketed customer support interactions. You should be warehousing and mining that event data yourself, not outsourcing the ownership and analysis to a one-size-fits-all SaaS. (Disclaimer: Snowplow co-founder :-)
