Overview
E-Discovery & Litigation Support Services companies provide electronic-discovery management, document review, digital forensics, and court reporting to law firms and corporate legal departments. Unlike the practice areas above, these are services and technology businesses, not law firms, so they are freely acquirable and have drawn heavy private-equity consolidation (Consilio, Epiq, KLDiscovery and others).
Revenue blends per-matter project work with recurring platform hosting and managed-review subscriptions, increasingly delivered through technology and offshore review capacity. It is a consolidating, tech-and-labor business that sits alongside the law firms it serves but is legally distinct from them.

This is the one genuinely buyable segment in legal. These are technology-and-services companies, not law firms, which is why PE has rolled them up hard (Consilio, Epiq, KLDiscovery). The $9.1B undercounts the real market: pure e-discovery software is classified with technology, so the figure captures the court-reporting and managed-review labor more fully than the platforms. Only 25 firms exceed 500 employees, so most exits are sponsor-to-sponsor rather than to a strategic.

Geographic concentration
Litigation-support firms cluster where the litigation is, not where the elite law firms are. Nevada, Florida, Louisiana and Arizona all carry well above their share, while New York and California (the traditional legal centers) sit at the national average. This is a demand-driven map: high case volume and document-review work concentrate in the Sun Belt's litigious, fast-growing markets.
