Interpath Unlocks New Investigative Workstreams with Relativity aiR for Case Strategy

How did they do it?

• Accelerated fact discovery in a high-profile fraud matter spanning millions of documents
• Replaced manual review with a scalable investigative workflow, enabling earlier insight and case understanding
• Improved momentum, confidence, and decision-making across the case team

Finding Signal in a Decade-Long Fraud Investigation

Interpath – a Relativity partner specialising in deals, value creation, forensic, and restructuring – was appointed liquidator on a high-profile fraud matter that had been ongoing for over a decade.

The investigation involved close to five million documents, sourced from dozens of systems, third parties, historic productions, and scanned paper records. The objective was clear but considerable: build a reliable factual record to support fund distributions – while also ensuring that specific listed individuals and their investments were identified and excluded.

Building fact chronologies and summaries required manual review followed by labor-intensive synthesis in Word documents. With approximately 5,000 search terms, inconsistent metadata, and fragmented workspaces, defining where to begin was a challenge in itself.

The scale and complexity of the data significantly increased the effort required to initiate review. As a result, the review process was delayed while the team worked to establish an effective, robust and defensible approach.

The Turning Point: Introducing Relativity aiR for Case Strategy

As early adopters of Relativity aiR for Case Strategy, Interpath explored how this new generative AI technology could support such a complex, data-intensive investigation. The team saw immediate value – particularly where understanding entities, timelines, and factual relationships was more important than legal argument.

Using aiR for Case Strategy, Interpath generated fact chronologies at scale, created entity-focused summaries using witness statement outputs, and produced clear, digestible document summaries for subject matter experts who were not lawyers.

After an initial test run on a small data set, the team was sold. The facts, document summaries and document ratings (Helpful/Harmful) were so on target that Interpath Director Matthew Dumenil said, “After that, there was no turning back.”

A New Investigative Workflow with aiR for Case Strategy

Interpath used aiR for Case Strategy to fundamentally reshape how they approached investigation work, including:

• Fact Generation: Automatically extracted and organised key facts across hundreds of documents
• Entity Summaries: Used witness statement functionality to build structured summaries for each entity under investigation
• Chronology Building: Created ordered timelines that helped the team quickly understand the story behind the data
• Expert Enablement: Provided clear summaries that allowed experts to focus on analysis rather than document digestion.

Subject matter experts reviewed and validated these outputs before sharing them more broadly with the case team – ensuring confidence, accuracy, and defensibility.

While aiR for Case Strategy was the centerpiece, Interpath also leveraged Relativity aiR for Review to conduct targeted, issue-focused reviews within the broader investigative workflow – demonstrating how aiR solutions work together across stages of a matter.

The Impact: From No Process to a Scalable Workstream

With aiR for Case Strategy, Interpath unlocked an entirely new workstream.

Key Outcomes

• Enabled investigative workflows at scale
• Transformed a resource intensive, manual task into a structured, repeatable process
• Improved engagement and momentum across the case team
• Allowed earlier sharing of findings, drafts, and summaries for collaborative refinement

One project manager noted: “The chronology is very helpful and enhances a manual review, as it orders everything for you and sets out the story and timeline of events.”

Beyond efficiency, aiR enabled the team to focus on creative and strategic elements of the process.

Why It Matters: Strategic Focus Over Manual Effort

aiR for Case Strategy didn’t just save time – it shifted where effort was spent. Instead of getting bogged down in document-level tasks, Interpath’s team could focus on identifying high-risk investments, investigating suspicious connections and making informed, defensible decisions.

As one stakeholder summarised: “With aiR for Case Strategy, we have a scalable process for building fact chronologies or entity summaries. It has introduced a new workstream that transformed how we handle investigations.”

Looking Ahead: Expanding the Role of aiR

Building on this success, Interpath plans to deepen its use of Relativity aiR across future investigations. aiR for Case Strategy can accelerate fact discovery, generate chronologies, and create entity-level summaries to enable earlier understanding of complex data, while aiR for Review supports targeted, issue-driven document analysis within the broader workflow.

Together, these capabilities allow Interpath to move from manual, reactive review to a scalable, insight-led investigative approach, laying the foundation for faster, more defensible decision-making in increasingly complex matters.

“Press go. Try it. Don’t let prompts deter you – you can always change them. aiR for Case Strategy can evolve your workflow in ways you don’t expect.”
