Ask HN: What's your startup's analytics setup?

Choosing analytics solutions for the startup I'm working at has proven to be more daunting than I imagined. There are many services to choose from and it's not immediately obvious how you should choose from the many offerings to get not only complete analytics coverage, but also do so in a way where you can integrate them all to get a complete picture without any mismatch. There is too much marketing speech copy on the sites of many analytics startups to properly evaluate them without wasting time and effort to signup, configure and use each one long enough to understand the value they provide. Off the top of my head there are services like Google Analytics, Mixpanel, RJMetrics, Omniture, KISSMetrics, Hubspot, GinzaMetrics, Crowdbooster, GoodData, Totango, MailChimp's Analytics 360,Beevolve, SocialBlaze, CoTweet, etc. etc. etc. Given all the options out there, what are considered the must have analytics solutions for startups? What are people doing about integrating the myriad solution
