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.

Why LineageAI had to exist.
Why LineageAI had to exist.
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.
Contracts evolve. Most tools don’t.
They get amended, redlined, extended, split across PDFs—and yet most systems treat each document like a standalone artifact.
That strips away the context that makes your terms enforceable, traceable, and strategic.
LineageAI changes that.
It reasons through your entire contract history—so you always know what governs, when it changed, and why it matters.
Unlike traditional market data service providers, we didn’t build LineageAI™ on outdated interfaces, offshore labor, or manual processing queues.
We built a system that reasons in real time—connecting documents, resolving conflicts, and surfacing governing logic with precision.
They extract. We reason.
They store. We connect.
They summarize. We trace.
And when your workflow requires traditional formats—summary views, audit tables, or structured exports—we deliver those too.
This is how you move from contract storage to contract strategy—without compromise.

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.

Temporal Awareness
Preserves context as terms evolve over time and determines what is actually in force now across changing documents and transactions.

In-Force Truth
Interprets overlapping, amended, and superseded terms to establish the governing truth behind rights, obligations, pricing, and approvals.

Evidence-Backed Intelligence
Surfaces answers, insights, and alerts with lineage back to source language, giving teams defensible context for action.

Signal-to-Intent Linkage
Connects documented intent to execution signals like invoices, renewals, usage, approvals, and compliance activity to verify whether the business is operating as agreed.

Put LineageAI™ to work
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.

For Legal, Finance & Compliance Teams
Market Data
The burden sits in the middle.
Market 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 market data leaders can shift from reactive coordination to proactive control.

Finance
Manual reviews. Mismatched invoices. Lost leverage.
Finance teams are tasked with reconciling spend—often without clarity on what was agreed, amended, or superseded.
LineageAI™ traces every charge to its contract source—flagging pricing violations, scope creep, and silent changes before they impact your budget.

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.
