The Lighthouse Approach
The team implemented both IQ Review and IQ Priv, combining AI analysis with disciplined managed review execution. Key elements included:
- AI-supported relevance review and a team of 30 contract attorneys for documents that required eyes-on review
- Privilege review, privilege log and names legend automation via AI
- AI image analysis for visual and scanned content
Two separate AI models were trained to address differing responsiveness criteria across custodial groups, ensuring precision without sacrificing defensibility.
Results
Lighthouse successfully processed 7.5M total documents across both collections. Because our AI models remain largely stable even with new documents, analysis of the second phase of collection was able to start immediately.
LighthouseIQ-powered analysis meant that only 2,500 total contract review hours were needed. Using AI insights, our contract review attorneys maintained high review velocity across responsiveness, privilege, and PII review streams.
The approach delivered FTC-ready defensibility under close regulatory scrutiny while enabling rapid adaptation to an evolving regulatory scope. Through expert coordination across legal, technical, and review teams, the engagement delivered predictable, consistent performance even under compressed timelines and shifting requirements.
