FAQ

How does SeatMap detect a zombie Slack account?

SeatMap reads your Slack seat roster and cross-references each user's last_active_at timestamp. Anything inactive for 30+ days is mechanically flagged as a ghost.

Will revoking a zombie Slack seat break anything?

No. Reclaim is reversible inside your Slack admin console for the first 30 days, and SeatMap logs every action in your audit trail.

What does this cost?

Starter is $19/mo. Growth ($199) unlocks Slack alerts and auto-reclaim. Scale ($499) adds Credential-Sharing Velocity checks for compliance teams.
