Percentages are of the 20+ employee universe. 20–99 and 100–499 are the lower-middle market; 500+ is at scale.

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; 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.
