PROFESSIONAL SERVICES — LEGAL (MID-SIZE LAW FIRMS)

Doc review collapses. Matter pricing + proprietary AI is how mid-size firms hold ground.

Mid-size firms (50-500 attorneys) sit between BigLaw resources and ALSP cost. AI compresses contract review and eDiscovery 70-80%, threatening hourly-billing economics. The opportunity is upward: matter-based pricing, AI-driven legal-ops services, and proprietary precedent libraries that make clients harder to leave.
