I am currently exploring solutions to track metrics for my startup. KissMetrics and Mixpanel are doing good jobs, but they are quite expansive and not very customizable for an early-stage startup. I am looking more for a tool that aggregates the data and syncs metrics from various sources.
What's the startup?<p>Without thinking of what is available through Google Analytics, Kissmetrics, Mixpanel etc .- what are the single most important factor of your startups success?
