Analytics is a crowded space, with plenty of services looking to help you turn your visitors into engaged, paid customers. KissMetrics is the latest to join the fray, and it's offering a solution that's both straightforward and powerful. As it comes out of stealth, the company is also revealing its funding: in 2008 it closed a $1 million seed round led by True Ventures, and in mid-2009 it closed a $3 million round led by Polaris Ventures. The company also has investments from SoftTechVC, Felicis Ventures, and Angels including Dave McClure, Mark Goines, Shervin Pishevar, Bobby Yazdani, and Nils Johnson. At this point, KissMetrics is built around one type of analysis: the conversion funnel, which shows you how many users are dropping off during your signup flows (and can hopefully help you figure out why). You can customize these graphs by tracking different variables, but Cofounder Hiten Shah says that you won't find a dizzying array of other options. The goal, he says, was to get this one key tool to work very well before branching out (though other tools will follow).
