Launch Recap with PostHog and Mixpanel

For a squad that ships on Tuesday and wonders on Friday whether anyone is using it. One prompt pulls adoption and retention for the launch cohort, writes the narrative, and posts it to your product channel with no manual dashboard stitching.

The grind

Launches go dark after the demo

Here's what doing this by hand looks like today, and why it doesn't scale.

The feature ships, the Slack post goes out, and then nothing. Nobody checks whether it landed until someone asks in the next planning, and by then the cohort is stale.
Adoption data lives in PostHog and retention lives in Mixpanel, and nobody opens both.
The launch recap never gets written because there is always a new launch.
Feature usage drops off quietly while the team moves on.

MewCP collapses all of this into one prompt. Here's what that looks like.

The flow

5 steps · 3 servers

Your agent runs it end-to-end

Identify the launch cohort, meaning the users who first saw the feature after the ship date.

Pull adoption, meaning the percentage of active users who engaged in week one.

Pull the seven day retention for the cohort from Mixpanel.

Compare it against the pre launch baseline and the goals you set.

Post a four line recap to your product channel with adoption, retention, a verdict, and what to watch next.

The payoff

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.

Paste this into Claude, Codex, or any MCP-connected agent. It'll connect your apps and run the task from start to finish.
