Like most other startups using the lean startup methodology, we’ve become pretty obsessed with tracking data. We track all kinds of stuff, from internal product metrics to external referrals to conversions via the various funnels we’ve set up. We rely on these numbers to help us make key product decisions, to tell us where we should focus our marketing efforts, and generally to find out what’s working and what’s not. For a company still wiggling our way into product/market fit, these numbers are our currency, and it’s important that we get them right.
