DN Hub Reduces Manual Data Notification Work to Seconds

LONDON, 30 June 2026 – Crown Jewels Consultants (CJC) has launched ‘Data Notifications Hub’ (DN Hub). This self-service tool automates the capture, validation and operational management of exchange and vendor Data Notifications for financial firms. DN Hub helps market data teams identify affected users, applications, services, pricing impacts and permissioning changes in seconds.

Data Notifications are change notices issued by exchanges and data vendors that can affect market data usage, pricing, licensing, permissions, applications and downstream services. They are a critical part of market data administration, but many firms still rely on manual processes involving emails, spreadsheets, workflow coordination and ticketing systems to assess the impact of changes and ensure they are actioned correctly. DN Hub streamlines this process by automatically comparing Data Notifications against usage and permissioning data, enabling firms to assess operational, commercial and permissioning impacts more quickly and consistently.

DN Hub provides operational workflows, management reporting, auditability, severity classification, and integration with ITSM and ticketing systems, helping organisations improve governance while reducing operational effort. CJC’s Commercial Management team has already deployed DN Hub within its managed service to support clients, reducing hours of manual work to seconds. The platform is now available to financial firms as a self-service tool.

What DN Hub Does

• Captures and validates exchange and vendor Data Notifications.
• Compares notifications against usage and permissioning data.
• Identifies affected users, applications, services, pricing and entitlement changes.
• Supports auditability, severity classification, reporting and ticketing workflows.

DN Hub is available as a standalone deployment for internal market data teams or as part of CJC’s commercial managed service offering, combining automation with specialist market data expertise.

DN Hub was built to meet the real-world operational requirements of CJC’s commercial managed service teams, which support large and complex financial institutions. Within these environments, usage and permissioning files can contain thousands of users, applications, exchanges, services and entitlement relationships, making manual Data Notification analysis increasingly difficult to scale.

By automating notification analysis and impact assessment, DN Hub enables market data teams to:

• Reduce manual processing effort.
• Improve operational response times.
• Increase visibility into pricing and licensing impacts.
• Reduce the risk of missed changes and service outages.
• Strengthen governance and auditability.
• Support operational workflows through integrated ticketing processes.
