Private where it must be. Frontier everywhere else.
Matterwall routes every prompt by client, matter, and outside-counsel guideline (OCG). Privileged work goes to frontier-class models on hardware only your firm controls. Everything else goes to the best public API. One policy engine, and no matter ever sits in someone else’s cloud.
We'll show you which of your clients' guidelines your current AI tools already violate. The audit takes two weeks and costs nothing.
Every firm is getting the same question
Latham built its own AI stack: 900 technologists, a hundred of them on AI, a colo cage, and three years. Every other firm’s CIO walked into Monday’s partner meeting and got asked what their version is.
You don’t have a hundred ML engineers. You also don’t get a choice about the constraint that matters.
Outside-counsel guidelines are the forcing function. A growing share of your clients now prohibit third-party AI on their matters. That doesn’t mean “the vendor must sign a DPA.” It means prohibited. Most firms can’t tell which matters are covered, and almost none can enforce it at the point of use.
That isn’t a model-quality problem or a cost problem. It’s a question of where the data goes, and of not marrying one vendor. Matterwall solves exactly that.
One operating loop, not a rack of boxes
Matter-aware router
A policy engine keyed on client, matter, and OCG terms. Restricted traffic goes to your private stack. Unrestricted traffic goes to whichever frontier API is best that week. Lawyers see one interface, compliance sees one log, and your GPUs stop being a science project and become a compliance artifact.
Private stack, refreshed quarterly
The latest open-weight frontier model on hardware dedicated to your firm: a colo cage, a dedicated cloud tenancy, or a DGX Station on-prem. We benchmark every release against the public frontier on legal task suites, so you know precisely what you're trading for privacy. Today that's about one quarter behind on most tasks. When it's more, we'll tell you.
DMS-native retrieval
Grounded in iManage and NetDocuments, with matter walls enforced at retrieval rather than bolted on afterward. The model can only see what the lawyer asking could already see.
Firm-tuned models
Fine-tune on your own work product. Latham's line, that no AI company can replicate its lawyers, should be true of your firm too.
Why not just…
…use Harvey / ChatGPT Enterprise?
Use them. When a matter is restricted, Matterwall is the infrastructure they run on. We don't compete with Harvey. We make Harvey allowable on more of your matters.
…buy two GPU boxes and hire an engineer?
You can. Then you own model selection, quarterly refreshes, eval harnesses, OCG mapping, DMS integration, and the on-call rotation. That's a team, not a hire. We are the team.
…wait for the labs to offer on-prem?
When they do, it becomes one more route in the router. Matterwall is multi-vendor by design. The private stack gets cheaper and the policy layer gets more valuable.
Your hardware. Our operating loop.
Matterwall never puts GPUs on our balance sheet, and never hides them in your subscription. Your firm buys or leases the hardware directly.
Stack live in weeks rather than quarters
Managed operations: refresh, eval, monitoring, on-call

Beyond law
Same guideline structure, different acronym. Matterwall also serves accounting firms, investment-bank legal and compliance groups, sovereign wealth funds, and government contractors: anywhere client-imposed restrictions meet an appetite for AI.
Find out which clients you're already out of compliance with.
The OCG audit is free and takes two weeks. It produces a matter-by-matter map of AI restrictions across your client base and, usually, the budget line to fix it.
