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 sitting alongside — but legally distinct from — the law firms it serves.

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.
