Jared Miller on Bottom Up by David Sacks

Good stuff. Another useful dimension to add once you’ve settled on the right engagement metric is to segment by (age) cohort. This assumes your startup has enough customers in each age bracket to field a significant sample and that it’s been in operation long enough to field some more mature cohorts. Being able to isolate engagement and churn by cohort, and being able to trend these metrics by cohort, gives an added layer of insight as to where your onboarding and customer success efforts are working or need improvement.
