Across 185 workspaces audited this week, the median team is sitting on 22.8% ghost seats — about $8,196/year of reclaimable spend per company.

Slack led the waste board at 46.2% inactive seats, driven by trial creep and stalled cross-team pilots. Slack came in at 26%, Microsoft 365 at 26.7%, and Salesforce at 18.7%.

SeatMap.AI operators reclaimed a combined $122,220 in annualized spend the week of 2025-09-22 — most of it from routine contractor and role-change cleanup, not one-off big wins.
