LineageAI™ by PostSig
The
Cross-Document Intelligence
Platform
LineageAI™ is the intelligence foundation behind PostSig. It connects contracts, amendments, invoices, clauses, and related records into a live lineage graph, tracks how terms change over time, and determines what is actually in force now.
Built on that platform, PostSig applications turn documented intent into decision-ready intelligence across renewals, billing, compliance, obligations, and risk.

Lineage AILineage AILineageAI™ AssistantThe Platform Behind PostSig
The Platform Behind PostSig
LineageAI™ is not a single-document AI tool.
It is PostSig’s cross-document intelligence platform, built to understand agreements as part of a living system. It preserves context as records evolve, resolves what has changed and what governs now, and connects that understanding to execution signals like billing, usage, renewals, approvals, and compliance events. That is how PostSig closes the gap between documented intent and real-world execution.
What Makes LineageAI™ Different
What Makes LineageAI™ Different
LineageAI™ is different because it does not analyze documents in isolation. It reasons across related agreements, amendments, side letters, invoices, and other records, preserves context as terms evolve, and determines what is actually in force now by connecting documented intent to execution signals like renewals, usage, approvals, and billing.

Cross-Document Reasoning
Connects agreements, amendments, side letters, invoices, and related records into a single lineage—so terms are understood in context, not in isolation.

LineageAI™ works
for you.
for you.
LineageAI™ doesn’t just show you contract terms.
It tells you what’s currently in force, how it changed, and why it matters—with reasoning logic that turns static documents into dynamic business tools.
Most teams review contracts only when something goes wrong.
PostSig changes that—giving you the clarity to act early, the insight to negotiate confidently, and the tools to stay aligned across legal, finance, and compliance.
This is how contracts move from background noise to operational advantage.

Data Teams
The burden sits in the middle.
Data teams sit between Legal, Finance, and Ops—without the tools to track obligations, enforce terms, or manage vendor complexity.
LineageAI™ connects the dots—linking clauses, documents, and context—so data leaders can shift from reactive coordination to proactive control.

Legal & Compliance
Legal &
Compliance
Missing clauses. Unclear ownership. Regulatory risk.
It’s hard to enforce terms or prove compliance when you don’t know what’s currently in force—or where gaps live across your agreements.
LineageAI™ gives Legal and Compliance teams visibility into clause coverage, amendment history, and regulatory readiness (e.g., DORA)—so nothing slips through the cracks.
Missing clauses. Unclear ownership. Regulatory risk.
Operations
Disconnected workflows. Vendor sprawl. No single source of truth.
Ops teams are stuck stitching together notes, emails, and spreadsheets just to answer basic questions: What are we paying for? Who uses it? When does it renew?
LineageAI™ centralizes vendor relationships, contract lineage, and performance metrics—so operations teams can stay ahead, not catch up.
Disconnected workflows. Vendor sprawl. No single source of truth.
