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.

Characteristics

  • Balanced cost base: payroll is 30% of revenue, leaving room to scale margin without cutting staff
  • Thin strategic-buyer pool: only 25 firms exceed 500 employees, so exits skew sponsor-to-sponsor
  • A services and technology business: freely acquirable, unlike law firms.
  • Technology and offshore review capacity drive the cost structure.
  • Recurring hosting and managed-review revenue underpin the roll-up thesis.

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.
