LineageAI™ by PostSig
The Reasoning Engine for Post-Signature Contract Intelligence
LineageAI™ is the intelligence layer behind PostSig—built to reason across your entire contract stack, not just extract fields.
It connects disparate documents with each other. Seamlessly. In real time. So you can validate decisions, enforce truth, and catch risk—without digging through dozens of files.

Why LineageAI Had to Exist
Why LineageAI Had to Exist
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Unlike traditional market data service providers, we didn’t build LineageAI™ on outdated interfaces, offshore labor, or manual processing queues.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.
Contextual reasoning when it matters. Familiar outputs when you need them.
This is how you move from contract storage to contract strategy—without compromise.

How LineageAI Works
LineageAI™ is more than OCR, tagging, or search. It combines parsing, linking, and temporal reasoning to understand contract structure and evolution in real-world terms.

Document Nesting & Relationship Mapping
Automatically links MSAs, service orders, amendments, off-paper terms, and invoices—structuring them into a logical “family tree.”

Temporal Clause Resolution
Clauses change. LineageAI™ reasons through effective dates and superseding logic to determine which version governs now.

Cross-Document Term Reconciliation
When a value appears—on an invoice, in a workflow, during a renewal—LineageAI™ traces it back through layered agreements to validate its origin.

Compliance Logic Evaluation
Goes beyond keyword detection. LineageAI™ evaluates full clauses against regulatory frameworks—like DORA—and flags contracts that fall short.

Make Contracts Work for You
Make Contracts Work 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
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.
