Operate from facts.Not fiction.
What was agreed at signing may not be what governs execution today. PostSig turns the documents that define your business into operating intelligence — so teams can act from the right information at the right time.
Operate as agreed.
What applies today
Terms, rights, obligations, pricing, approvals, usage, and business context.
What changed
Amendments, side letters, superseded terms, pricing shifts, renewal changes, and missing records.
What needs attention
Billing discrepancies, missing clauses, unsupported invoices, unresolved obligations, and expired rights.
Why you can trust it
Source documents, clauses, lineage, reviewer status, approvals, and decision history.
The truth doesn’t end at signature. And it rarely lives in one document.
The agreement gets signed. Then the record starts to grow.
Invoices arrive. Amendments change terms. Usage records shift the context. Approvals happen in another system. Side letters, waivers, notices, and renewal events alter what the business can rely on.
Then the question becomes urgent: What applies now? What changed? What are we allowed to do?
That is when manual reconstruction breaks down. Teams stitch context together by hand, compare versions, scan clauses, hunt through folders, and hope nothing important is missed.
Agreement gets signed
The original commercial, legal, or investment intent is captured.
The record starts to grow
Amendments, invoices, usage records, service orders, approvals, notices, and side letters change the operating context.
The question becomes urgent
A payment, renewal, approval, report, right, obligation, or AI workflow needs an answer now.
Manual reconstruction breaks down
Teams compare versions, scan clauses, and patch together context by hand — usually under pressure.
Value leaks.
Economic terms drift across renewals, invoices, and spend.
Authority drifts.
Control weakens when approvals and owners are unclear.
Trust erodes.
Teams cannot tell which facts are current, which terms govern, or which answer can be used.
The truth is in your documents. LineageAI™ puts it to work.
Your agreements, amendments, invoices, side letters, usage records, approvals, and obligations hold the intelligence your business runs on: money, rights, pricing, restrictions, renewals, reporting, ownership, risk, and authority.
But that intelligence is locked inside PDFs, folders, trackers, disconnected systems, and institutional memory.
LineageAI™ understands how those records relate, reasons across change and time, and puts the full story together — giving teams the operating intelligence they need to move with conviction.
LineageAI™ returns more than a conclusion.
It shows the source path behind the answer: the documents involved, the changes that matter, the evidence used, the reviewer status, and the decision record the business can rely on.
Full-record intelligence
Connect agreements, amendments, side letters, invoices, records, approvals, usage data, and operating signals into one answer path.
Reasoning across change and time
Understand what was amended, superseded, repriced, waived, restricted, missing, inconsistent, or no longer applicable.
Source-grounded answers
Return the answer with the documents, clauses, records, lineage path, and operational proof behind it.
Audit-ready
Preserve reviewer status, approvals, comments, audit history, and the context behind what the business did next.
Operate from
the whole truth.
PostSig supports high-stakes teams that cannot afford partial context. Not fragments. Not one-off summaries. The full operating truth behind the work that moves the business.

Answers.
Not summaries.
PostSig gives teams business answers from the full post-signature record — not summaries of one document. The answer can appear in a dashboard, an assistant response, or a governed MCP workflow, but it comes from the same source-backed intelligence layer.
