Mantle Portal

Customer

A large U.S. State Investment Management Board overseeing $26.3 billion in assets across approximately 300 funds. This institution supports the retirement security of over 500,000 public servants.

The Challenge

Before implementing Mantle, the board’s back office was overwhelmed by manual document management. Highly educated professionals were spending 40 hours per week simply downloading, filing, and manually processing documents. The fragmented nature of GP reporting created a high risk of human error in critical processes, where a single missed capital call could trigger penalties exceeding $1 million.


The Solution

The board implemented Mantle Portal to automate the end-to-end lifecycle of its private markets portfolio, including real estate, private credit, and private equity.

  • Automated Collection: Daily sweeps across major investor portals (e.g., Intralinks, Citco, SS&C) to capture capital calls, distributions, and K-1s.

  • Intelligent Classification: AI-driven identification of 15+ different document types with over 99% accuracy.

  • Enterprise Integration: Real-time bulk delivery of extracted data and renamed documents via secure SFTP to existing state accounting systems.

  • Audit Readiness: 100% audit trail coverage with source-to-pixel traceability for every number.


Measurable Results

  • 85% Cost Reduction: Achieved massive operational leverage by reducing manual processing time from 40 hours per week to just 2 hours.

  • 99%+ Accuracy: Eliminated manual data entry errors through AI-powered extraction and Mantle’s "Human-on-the-Loop" validation.

  • Risk Mitigation: Minimized the risk of missed deadlines and associated financial penalties through proactive tracking and alerts.
