Modernizing Market Data Management Without Platform Replacement
Connect what you're managing to what governs it, without disrupting the systems you depend on.
For enterprise market data teams, modernizing existing infrastructure presents a familiar dilemma: how do you gain new capabilities without disrupting the systems and processes that keep the business running?
Established platforms hold years of vendor records, inventory, allocation rules, and reporting structures. Organizations have built workflows, integrations, and institutional knowledge around them.
But there's a critical piece often missing: the connection between what's happening operationally and the contracts and commitments that govern it.
Closing that gap doesn't have to start with replacing your existing platform.
Connect what you're managing to what governs it.
An inventory system may identify a subscription. A financial report may show who pays for it. An invoice may reflect a new price. But are those records consistent with what was actually agreed?
The answer may depend on an original agreement, subsequent amendments, service orders, or pricing terms that have changed over time.
PostSig Contract Performance Management™ (CPM) connects these commercial and operational records through PostSig LineageAI™, establishing which commitments apply today and making the supporting evidence traceable.
That context transforms disconnected records into actionable intelligence. Teams can identify billing discrepancies, validate entitlements, understand obligations, and make better-informed decisions about vendor relationships.
It's the difference between knowing what's in your systems and knowing whether your business is operating as agreed.
Add intelligence without replacing your infrastructure.
PostSig can operate alongside established market data platforms, connecting the underlying commercial evidence while existing systems continue supporting daily operations.
Rather than committing to a full migration upfront, organizations can start with a specific vendor relationship or operational workflow, validate findings against their own records, and progressively transition capabilities as they're ready.
Because that intelligence isn't confined to the PostSig application, customers have greater flexibility in how they use it.
With PostSig MCP (Model Context Protocol), compatible AI tools and customer-built applications can access governed commercial intelligence, supporting evidence, and appropriate access controls.
That means more direct answers, greater control over reporting and workflows, and less dependence on specialized services to connect the dots.
Prove the value before you move.
In an evaluation with a European bank, PostSig tested core market data workflows using the institution's own records while its existing platform remained in place.
The evaluation uncovered an invoice discrepancy the legacy system’s configuration hadn't flagged and identified subscription assignments that needed further investigation.
It also established where additional integration and adaptation would be needed before transitioning production workflows.
Rather than making modernization an all-or-nothing decision, this approach lets organizations demonstrate value, validate requirements, and move forward with confidence.
The goal isn't simply to replace a legacy platform. It's to connect what your business does to what it's committed to, and give your teams greater control over both.
