Lighthouse

What Lighthouse does

Lighthouse is a technology-enabled eDiscovery and legal intelligence provider serving Fortune 500 corporate legal departments and AmLaw 100 law firms across litigation, regulatory, and compliance matters. The company operates a unified platform-plus-services model anchored by LighthouseIQ, its next-generation AI-powered legal intelligence suite launched in January 2026, which comprises four integrated applications — IQ Answers (LLM-grounded natural language document Q&A), IQ Case Strategy (issue-driven document surfacing), IQ Review (predictive relevance review), and IQ Priv (generative privilege identification and log drafting) — all built on a proprietary IQ Fabric foundation that has processed more than 1.4 billion documents and supports cross-matter reuse of 100K+ coding decisions. Lighthouse complements the platform with full-service eDiscovery offerings including forensics and collection, hosting and processing, managed document review, information governance, and legal hold consulting, integrating with RelativityOne and the Microsoft 365 ecosystem (including Microsoft Purview and Microsoft Copilot readiness assessments).

Lighthouse monetizes through a combination of subscription-based platform licensing for LighthouseIQ, project-based professional services engagements, and programmatic multi-matter arrangements, with pricing quoted per engagement rather than disclosed publicly. GTM is enterprise field sales targeting corporate counsel and law firm managing partners, supplemented by technology integrations with Relativity and Microsoft and event-driven demand generation through the annual Illuminations Summit and the Law & Candor podcast. Lighthouse holds five consecutive Band 1 Chambers and Partners rankings, Legal 500 Tier 1 status, and Provider of the Year recognition, and counts Microsoft, Cleary Gottlieb Steen & Hamilton, and multiple Fortune 500 pharmaceutical, healthcare, manufacturing, and retail enterprises among its reference customers.

The company is privately held with $56 million in disclosed private equity funding across 2012-2016 (Columbia Pacific Advisors, Spire Capital, CIT Group), has completed acquisitions of Discovia (2017) and Forexus GmbH (2018), and is led by CEO Brian McManus with Bill Mariano as CRO and Wes Moorhead as COO. Headquartered in Seattle with a global footprint spanning North America and Europe, Lighthouse reports a headcount of 1,001-5,000 employees and SOC 2 Type 2 and ISO 27001 certifications.
