Know by Friday whether Tuesday's ship moved the needle

Email Carly a few days after ship and she'll pull adoption and retention for the launch cohort, write the narrative, and post to #product — no manual dashboard stitching — so the squad that shipped Tuesday actually knows by Friday whether anyone's using it.

PostHog Mixpanel Slack

What Carly does

1. 01 Identify the launch cohort — users who first saw the feature after ship date
2. 02 Pull adoption — what % of active users engaged week-one
3. 03 Pull D7 retention for the cohort from Mixpanel
4. 04 Compare against the pre-launch baseline and the goals you set
5. 05 Post a 4-line recap to #product: adoption, retention, verdict, next watch

Every launch gets a verdict

No feature ships into silence. Within a week, the team sees whether adoption and retention moved — and decides whether to double down or fix.

Email this to Carly to kick it off.

Hey Carly,

We shipped the new feature on Tuesday and I want a real verdict by Friday. Can you identify the launch cohort in PostHog — users who first saw the feature after ship date — pull week-one adoption as a % of active users, then grab D7 retention for that cohort from Mixpanel? Compare against the pre-launch baseline and the goals we set, then post a 4-line recap to #product on Slack with adoption, retention, verdict, and what to watch next. No manual dashboard stitching needed.

Thanks!
