Legal builds put confidentiality first. Privileged documents need strict access controls, answers need citations, and a lawyer stays responsible for anything sent to a client or court.

## How to read this

A brief's industry comes from its title where that names a sector, otherwise from the buyer's stated industry. About 45% of briefs can be placed. Figures come from public project briefs from December 2025 to November 2026 and show what briefs offered, not what was paid. Hourly briefs are estimated from rate, length and workload. Industries need 30 priced briefs to be ranked, and are left out of rankings when one buyer makes up over a quarter of briefs. Counts under 5 are hidden. Momentum compares January to March with May to July, before collection widened, and is left out where one buyer is over 12% of briefs.
