Depthdata is a finance-focused analytics platform that connects to multiple AI vendor admin consoles via read-only APIs and normalises their differing usage, seat, and spend data into a single auditable schema. It labels every figure as measured, derived, or modelled so finance teams can confidently defend AI line items in budget reviews. The tool identifies dormant seats, duplicate tool coverage, and adoption gaps by department, ranked by recoverable spend. Depthdata baselines progress against a workspace's own first-month activity rather than industry benchmarks, making results specific and harder to dismiss. It intentionally discards conversation content at ingestion, operating entirely on metadata.
