Law.
Paralegal time is the bottleneck on matter progression. A conveyancing bundle, a disclosure pack or a contract-review triage has the same shape from file to file; the evidence does not. That is the seam where software earns its keep.
The firms
Mid-tier firms with 50 to 300 fee-earners carry a back office that has quietly become the most expensive part of the firm per recovered hour. The April 2025 rise in employer National Insurance landed there, not on the partner floor. The technology spend has already happened - practice management, a document store, Microsoft 365, time recording - and it is well understood. What is missing is the specific piece of software that sits on top of that stack and runs one repeatable workflow end to end, under supervision.
Workflows we build here
One at a time, each wired into the systems the firm already runs.
- Conveyancing matter bundle
- Title registers, searches, ID evidence, survey PDFs and client correspondence in; a structured matter pack out, with cited sources, a redline of adverse entries and a paralegal review queue ordered by risk.
- Disclosure pack
- Across a matter inbox and document store, a dated timeline of parties, amounts and counterparties. Privileged material flagged; a narrative brief with footnoted citations goes to the partner.
- Contract review triage
- A rules engine built from the firm's own playbook, with a language model explaining each deviation in context. Clean clauses move on; flagged ones go to a named lawyer with the precedent attached.
- Precedent and matter search
- Plain-English search over the firm's closed matters, precedent bank and procedures. Every answer cited to the source document, with partner-level permissions respected.
The cover sheet a Build of this kind would put on its output, with each field described rather than filled in.

Case studies
No published case study in law yet.
When there is one it will name the firm and carry measured numbers, with the firm's sign-off. Until then this page describes the work, not its results. If your firm would like to be the first, write to crofter@nullhex.io.
