What is the most important data to measure during the launch of your product?

hey there, sis launching? focus on engagement metrics. observe user interaction, pinpoint where they linger or bounce. understand why. this isn’t just clicks or views, it's about understanding behavior, dissecting interaction nuances. find the 'sticky' features, know what’s resounding with them. your early users are goldmines of insight, their behaviors, a guide to pivots or enhancements. with every data point, ask why. why here, why now, why this way? your product’s launch story is told through user behavior. listen, adapt. cheers, Karim.
