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 under a signed BAA, never retained and never trained on.
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, governed AI inside a single-tenant cluster — on-prem, private, or air-gapped, delivered by engagement.
ExploreWhy institutions choose LexSteward.
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.
Governed AI, privilege-safe
Client and privileged data is processed under a signed BAA with zero-data-retention terms — never retained by the provider, never trained on, isolated per firm and fully logged.
Data residency & sovereignty
Your data region is set at signup. Sovereign adds your own keys and single-tenant, in-region or air-gapped deployment, delivered by engagement.
SSO, roles & audit
Single sign-on (SAML/OIDC) rolling out, with 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 governed by default. Sovereign is designed so you hold the key, the aim being that we cannot read your protected content — it is delivered by engagement and is not a shipped configuration today. SOC 2 and sector frameworks are on our roadmap; we’ll never claim them before they’re earned.
See exactly how our AI and data handling work- Per-firm encryption, revocable keys
- US residency, set at signup (Canada, and in-region backups, on the roadmap)
- BYO-KMS & zero-knowledge, designed for Sovereign (by engagement)
- Audit trails (live); confidentiality report (preview, not switched on yet)
- SSO (SAML/OIDC, rolling out), roles, RBAC
Confidentiality you can put in a procurement packet.
Governed, no-train AI; per-firm encryption; minimum-necessary redaction; and a tamper-evident privilege ledger recording every AI action on every matter. Your team — and your clients — get a verifiable trail, not a marketing promise.
Review security & trustDeploy it your way.
From an in-region cloud tenant to an air-gapped sovereign cluster — the same platform, the posture you require. Sovereign postures are delivered by engagement, not self-serve.
Multi-tenant cloud
Isolated tenant in your data region (US today; Canada on the roadmap). 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.
