Lighthouse

What Lighthouse does

Lighthouse Document Technologies Inc., founded in 1995 and headquartered in Bellevue, Washington, is a privately held eDiscovery and information governance company serving Fortune 500 corporations and AmLaw 100 law firms across the United States, Europe, and Asia Pacific. Its core platform, LighthouseIQ, is an AI-powered legal-grade data management and intelligence offering composed of four modules — IQ Case Strategy (early case assessment), IQ Review (document review with advanced analytics), IQ Priv (privilege analysis), and IQ Answers (natural-language enterprise search) — layered over managed forensics, processing, and hosting services. Lighthouse also operates Spectra, a self-service SaaS eDiscovery platform, and maintains dedicated services for digital forensics, IP asset management, and information governance. LighthouseIQ is integrated with Relativity, Brainspace, Microsoft Azure, and Microsoft 365 (including a custom Linked Files solution for Microsoft Purview), and the company holds SOC 2 Type 2, ISO 27001, HIPAA, GDPR, CCPA, and UK GDPR certifications.

The company monetizes through a hybrid model: large, project-based professional services engagements for managed review and eDiscovery execution, complemented by subscription SaaS revenue from Spectra with tiered annual support. Distribution is enterprise field sales led by a dedicated CRO, Client Success organization, and Sales Enablement, with named Fortune 500 relationships (Microsoft, UBS, Barclays, a Fortune 500 pharmaceutical company) and AmLaw 100 firm partnerships. Lighthouse has remained privately held, has no parent company, and has executed at least one inorganic growth move — the 2021 acquisition of H5 — to extend document review and analytics capabilities.

Direct peers

• Relativity (Reveal Holding): Relativity develops RelativityOne, the dominant cloud eDiscovery review platform that Lighthouse integrates with and hosts for clients. Both companies sell eDiscovery technology and managed services to AmLaw 100 firms and Fortune 500 enterprises on overlapping matters.
• DISCO: DISCO is a leading cloud-native eDiscovery and legal technology platform competing directly with Lighthouse's LighthouseIQ and Spectra products for law firm and corporate matter work, with comparable AI-driven review capabilities.
• Epiq: Epiq is a global managed services and eDiscovery provider offering document review, forensics, and information governance to Fortune 500 corporations and law firms — directly overlapping Lighthouse's core services book.
• KLDiscovery: KLDiscovery (successor to Kroll Ontrack) provides eDiscovery, data forensics, and managed document review services globally, competing head-to-head with Lighthouse's forensics and review capabilities in the same enterprise market.
• Consilio: Consilio is a legal services and eDiscovery managed review provider with global delivery centers serving AmLaw firms and Fortune 500 clients — a near-direct services competitor to Lighthouse's managed review and information governance practices.
• HaystackID: HaystackID provides AI-powered eDiscovery, managed review, and digital forensics for complex litigation and investigations, competing with Lighthouse in regulated-vertical and law firm matter engagements.
• Logikcull: Logikcull is a self-service eDiscovery SaaS platform targeting in-house legal teams and mid-market law firms — directly comparable to Lighthouse's Spectra self-service offering.
• Reveal: Reveal (now combined with Relativity under Reveal Holding) offers AI-powered eDiscovery and document review platforms and competes directly with Lighthouse's LighthouseIQ suite across enterprise and law firm segments.

Broad incumbents

• OpenText: OpenText (via its discovery and Magellan AI portfolio, formerly Micro Focus) provides eDiscovery and information governance as part of a much broader enterprise information management stack — a broad incumbent competing with Lighthouse in regulated industries.

Others

• Microsoft Purview: Microsoft Purview is Lighthouse's named integration partner but also an emerging competitor as Microsoft embeds eDiscovery and AI-driven compliance capabilities natively within Microsoft 365 — a converging ecosystem player worth monitoring.
