The operating system for institutional legal.
One private, sovereign-capable system to run marketing, matters, billing, and client collaboration — at the scale of a large firm, a corporate legal department, or a government body. Deployed in your region, under your keys, with AI that keeps privileged data inside the boundary.
Custom pricing by deployment and scale. No self-serve checkout — we’ll scope it with you.
Built for three kinds of institution.
Pick the one that sounds like you — each has its own tailored fit.
Large & multi-office firms
You run 40+ lawyers across offices and serve sophisticated corporate clients.
Business development at scale, a corporate client portal with portfolios and spend, and one system to run every matter.
ExploreCorporate in-house legal
You’re a legal department, not a firm — no external clients, but plenty of internal demand.
An internal legal front door for the business, outside-counsel and spend management, and legal-ops reporting.
ExploreGovernment & sovereign
You’re a public body, tribunal, or regulated institution with hard data-sovereignty rules.
Your region, your keys, in-boundary AI inside a single-tenant cluster — on-prem, private, or air-gapped.

One system, end to end
Acquire, run, bill, and collaborate — marketing, matters, calendar, documents, billing, and a client portal in one place. Not five tools stitched together.
In-boundary AI, privilege-safe
Client and privileged data runs on models inside our boundary — never sent to a public AI, never trained on. A frontier brain is opt-in only, for the work you choose.
Data residency & sovereignty
Your data region is set at signup and holds all the way down to backups. Sovereign adds your own keys and single-tenant, in-region or air-gapped deployment.
SSO, roles & audit
SAML/OIDC single sign-on, role-based access across offices and teams, and an audit trail on everything that matters.
No lock-in, ever
Everything you create is exportable, anytime. The moat is that the system gets smarter about you — not that you’re trapped in it.
Confidentiality isn’t a setting. It’s the architecture.
Per-firm field-level encryption, data residency fixed at signup, and AI that keeps privileged data in-boundary by default. On Sovereign, you hold the key — making us technically unable to read your protected content. SOC 2 and sector frameworks are on our roadmap; we’ll never claim them before they’re earned.

Deploy it your way.
From an in-region cloud tenant to an air-gapped sovereign cluster — the same platform, the posture you require.
Multi-tenant cloud
Isolated tenant in your data region (US or Canada). Fastest to stand up; per-firm encryption and isolation throughout.
Single-tenant
A dedicated instance for your institution — your own database, storage, and AI pool, in your region.
Sovereign / on-prem / air-gapped
On your hardware, outside the public cloud — including air-gapped. NetApp storage + NodeWeaver compute + LexSteward. Availability by engagement.
Sovereign, on-prem, and air-gapped deployments are delivered with our infrastructure partners and scoped per engagement.
How we bring you on.
Scope & deploy
We scope your deployment, region, SSO, and roles — then stand up your instance in your data region.
Migrate, read-only
We connect to your current system read-only, read the whole practice, and rebuild it here — matters, contacts, documents, history — seeding your institutional memory from day one.
Run & support
Go live with enterprise SLAs and tiered support. Your data stays exportable the entire time — no lock-in.
