Across 429 workspaces audited this week, the median team is sitting on 26.9% ghost seats — about $9,494/year of reclaimable spend per company.

Slack led the waste board at 46.5% inactive seats, driven by trial creep and stalled cross-team pilots. Slack came in at 31.8%, Microsoft 365 at 25.4%, and Salesforce at 21%.

SeatMap.AI operators reclaimed a combined $178,628 in annualized spend the week of 2026-04-27 — most of it from routine contractor and role-change cleanup, not one-off big wins.
