ABOUT GHOST TAX
Ghost Tax detects hidden financial exposure in SaaS, AI, and Cloud spending. We deliver corrective protocols, not dashboards.
OUR MISSION
Every organization has a Ghost Tax — the invisible cost of ungoverned technology spending. Inactive licenses, duplicate tools, ungoverned AI consumption, missed negotiation leverage. These costs compound silently, quarter after quarter.
We built Ghost Tax to make this exposure visible, quantifiable, and correctable. Not with another dashboard that requires months of integration. With a deterministic intelligence pipeline that delivers decision-ready output in 48 hours.
WHAT WE BELIEVE
Transparency over precision theater
We show confidence ranges, not false certainty. Every finding is scored and labeled: observed, inferred, or estimated. If we're uncertain, we say so.
Speed kills incumbent advantage
Traditional audits take months and cost hundreds of thousands. By the time findings arrive, the problem has compounded. 48-hour delivery changes the economics of decision-making.
Reports should sell themselves
A CFO shouldn't need a presentation to understand financial exposure. Our Decision Packs are designed to circulate internally without intermediaries.
Ranges, not point estimates
Financial exposure is inherently uncertain. We deliver ranges with confidence scoring. Anyone claiming exact figures is either lying or guessing.

TECHNICAL APPROACH
Zero system access
Detection runs from your company domain + public signals. No OAuth, no agents, no MDM. The analysis requires zero IT involvement to initiate.
21-phase NDJSON pipeline
lib/analysis.ts executes 21 deterministic phases in strict order. Each phase streams as NDJSON. Evidence layers appear before the executive summary — by design.
pgvector market memory
Supabase PostgreSQL 15 with HNSW index. 1536-dim OpenAI embeddings. 6 category indexes. Peer comparison uses cosine similarity against vendor baselines.
Confidence discipline
Scores are 0-85, never 100. Three tiers: observed signals, inferred patterns, estimated exposures. Each tier affects the confidence ceiling independently.
