Lighthouse Launches AI Platform for Legal Teams

Lighthouse has launched LighthouseIQ, an AI-based legal intelligence platform designed for eDiscovery, litigation, and investigations work.

Lighthouse unveiled LighthouseIQ on Friday, introducing an AI platform and application suite that accepts natural language input and produces analysis based on training across 1.4 billion documents. The company built the platform for corporate legal departments, compliance teams, and law firms handling eDiscovery, litigation, and investigations.

The platform addresses growing volumes of enterprise data and increased regulatory scrutiny. Legal teams face demands for faster answers while working with tighter resources, creating pressure to improve efficiency in document review and case preparation.

Early Adoption

Cleary Gottlieb Steen & Hamilton used LighthouseIQ during its early rollout. The firm's eDiscovery and litigation technology group applied the software in a recent matter.

"Before LighthouseIQ, we did not have an efficient way to surface key documents early enough to influence case strategy," said C.J. Mahoney, Partner and Global Head of eDiscovery and Litigation Technology at Cleary Gottlieb Steen & Hamilton. "With LighthouseIQ, we can get to critical insight much faster and make informed decisions earlier in the lifecycle of a matter."

Mahoney described using the platform to test a damages theory for a client. The firm needed to substantiate the claim and arrive at a defensible calculation. LighthouseIQ enabled the team to complete this work with data-backed confidence, allowing the matter to resolve quickly and favorably.

Technical Foundation

Lighthouse built the platform on IQ Fabric, a technical layer that standardizes data while preserving fidelity. This foundation provides interpretation and insight capabilities, plus workflow coordination for tools and AI systems.

The platform integrates with Relativity, which many law firms and service providers use for document review and eDiscovery workflows. Lighthouse said this integration allows LighthouseIQ to fit into existing legal review processes.

The company reported that LighthouseIQ has processed up to 33 million documents in a single day. Output from the platform has been accepted by regulators including the FTC and DOJ, though Lighthouse did not specify the cases or contexts.

Application Suite

LighthouseIQ includes four applications that work together within the suite.

IQ Answers handles question-and-answer interactions with datasets using natural language prompts. The application targets faster retrieval of answers without waiting for review cycles.

IQ Case Strategy generates analysis and work product for matter strategy. This includes early case intelligence, narrative development, chronologies, timelines, and preparation for depositions and witness interviews.

IQ Review identifies responsive content across large datasets. Lighthouse describes the workflows as regulator-accepted and designed for speed and accuracy in complex reviews.

IQ Priv focuses on privileged material and privilege logging. The application combines generative and predictive AI to identify privileged content and produce privilege logs.

Leadership Perspective

CEO Ron Markezich connected the release to his focus on scaling AI for legal work. Markezich previously worked at Microsoft before joining Lighthouse.

"I came to Lighthouse with a mission to apply AI at scale to the legal industry," said Ron Markezich, CEO of Lighthouse. "LighthouseIQ is the result of our commitment to helping our customers gain clarity faster, act smarter, and move more decisively than ever before."

Lighthouse linked LighthouseIQ with its eDiscovery and information governance business. The company pairs AI systems with its staff of eDiscovery practitioners to deliver the platform's capabilities.

Lighthouse said LighthouseIQ is available immediately. The company offers a risk-free trial of IQ Answers for qualified organizations.
