126,000 Documents. 72 Hours. Actionable Intelligence.

Challenge

When a whistleblower allegation placed a company’s future in question, outside counsel needed answers immediately. Executives had to determine whether the allegations were credible, whether fraud or criminal exposure existed, and whether the business could continue operating—all within days.

The investigation involved more than 126,000 documents spanning email, collaboration platforms, messaging applications, and business records. A traditional review would have required weeks before attorneys could begin developing meaningful legal strategy.

With critical business decisions on the line, an Am Law 50 firm partnered with Lighthouse to rapidly identify the evidence that mattered most while maintaining a defensible investigative process.

Solution

Using IQ Case Strategy, Lighthouse and outside counsel replaced the traditional review-first approach with a question-first investigative methodology.

Rather than reviewing every document equally, counsel first identified the legal and factual questions that would determine the outcome of the investigation. Lighthouse then transformed those questions into a structured investigative workflow that rapidly surfaced the evidence most relevant to each issue.

Approximately 150 targeted investigative questions guided the analysis across more than 126,000 documents, including email, WhatsApp, Signal, Discord, ChatGPT conversations, and other business records.

As the investigation progressed, Lighthouse continuously identified, organized, and synthesized the most relevant evidence while attorneys refined investigative priorities and validated findings. Instead of spending weeks reviewing low-value material, counsel could immediately focus on the documents that informed legal strategy and business decisions.

IQ Case Strategy delivered a comprehensive merits assessment that included:

• Executive summary of key findings, risks, and unresolved questions
• Prioritized hot documents supporting and challenging each allegation
• Issue-based evidence summaries with integrated chronologies
• Structured evaluation of competing factual theories
• Document-level investigative coding and supporting data index

The result was more than a streamlined document review—it was an evidence-based strategic assessment that enabled counsel to quickly evaluate risk, advise leadership, and determine the appropriate path forward.

Impact

The investigation produced meaningful business results in less than three days.

• Completed the investigation in under 72 hours
• Reduced 126,000 documents to approximately 1,100 critical records
• Generated more than $335,000 in estimated cost savings compared to traditional review methods
• Enabled counsel to rapidly assess the credibility of the allegations, potential fraud, criminal exposure, and operational risk
• Equipped executive leadership with evidence-based guidance to make critical business decisions within days rather than weeks

“This engagement demonstrated what is possible when legal strategy and technology are developed together rather than applied sequentially. Together with Lighthouse, we reduced a 126,000-document review to the evidence that mattered most, completed the assessment in under 72 hours, and delivered a comprehensive merits triage that enabled the client to make critical business decisions with confidence. The collaboration generated more than $335,000 in savings while providing a level of strategic insight that traditional review methods simply could not deliver.”
