The institutional
memory for
your firm.
We are building FirmMemory, a private, sourced answer layer over every matter, memo, and decision your firm has produced. Built with you, behind your perimeter.
45-MIN WORKING SESSION
NDA-FIRST · NO SLIDES · FOUNDER-LED
NDA-FIRST · NO SLIDES · FOUNDER-LED
Your firm is a ledger of forgotten arguments.
Every matter knows something. None of it is searchable. So your firm pays to learn it twice.
We index it.
FirmMemory. A sourced answer layer — over everything you've ever produced.
- Always cited
- Ethically walled
- Tenant-isolated
- Built around the partner
FirmMemory does four things well. The rest, we'll build when a partner needs it.
01
Relevant matters.
The partner asks. The system finds the matters and the paragraphs that prove the answer.
02
Connected matters.
Chains matters together across practices, clients, regulators, and fact patterns so the bench reflects how the firm actually worked.
03
Sourced synthesis.
The relevant matters, read into a single answer. Every claim cited to a paragraph in a specific document.
04
Honest gaps.
Where the bench is thin, the system says so. No confabulation. No proxy precedent. The gap is the trust signal.
What we can build for you next: Expertise graph, argument library, automated matter onboarding, post-mortem capture. Scoped to your practice, not a feature checklist.
We don't sell software. We embed for a quarter, ship FirmMemory, then make ourselves optional.
One practice group at a time. Firm-wide rollouts fail. Earn them by making one group's life visibly better first.
Weeks 0–2
Listen
We embed with your team. We map where institutional memory is leaking. Output: a written diagnostic. Not a demo.
Weeks 3–12
Ingest
We connect to your DMS, mail, and CLE archives inside your perimeter. Nothing leaves. We build the corpus, retrieval, and citation layer. Weekly progress against agreed criteria.
Weeks 12–14
Hand off
FirmMemory goes live for the practice group that wrote the playbook. Partner approval gates rollout. We document. We train. We step back.
Q2 onwards
Optional
A retainer covers ongoing operation and the next capability if you want it. The retainer is optional. Some firms keep us on, some take the system in-house. Both work.
Pricing
Fixed-fee engagements. Not seat licences.
Pricing is published, not bespoke.
Discovery
£6,000
Two-week embed with one practice group. Output: written diagnostic and scoped pilot proposal.
Data preparation, where required, is scoped at discovery and priced separately. Full commercial terms are agreed in the master services agreement before pilot work begins.
Pilot build
£45,000
FirmMemory live for one practice group across a 12-week engagement. Includes discovery if you proceed within 60 days.
Your data is privileged. We treat it that way.
Built to the SRA Code, legal professional privilege, and GDPR. Not retrofitted.
Tenant-isolated by default
Each firm runs in a dedicated environment. No shared inference. No shared embeddings. No cross-firm contamination, including across our own client base.
No model training, ever
Your matters never enter a foundation-model training set. Contractually in our master services agreement, architecturally in our retrieval pipeline.
Inherits your ethical walls
Conflict screens and matter walls flow live from your DMS. We do not maintain a parallel ACL system that needs to be kept in sync.
Full audit log
Every query, every source surfaced, every answer. Exportable in a format your COLP and SRA-facing risk function will accept without rework.
GDPR & DPA 2018 compliant
Data Processing Addendum and Standard Contractual Clauses available pre-engagement.
Customer-managed keys
Your KMS, your rotation policy. Hardware-backed for partners who require it.

Field note: what we learned generating a 700-document synthetic legal corpus.
Holborn Carter LLP doesn't exist. The 114 matters, 739 documents, and 15,084 paragraphs in the FirmMemory demo were generated on purpose, so we could test citation enforcement, gap detection, and refusal discipline against a corpus whose shape we knew in advance. The trust-architecture argument, with the receipts.
Upcoming
The gap between RAG demos and production legal knowledge systems.
Citation enforcement, gap detection, refusal discipline — the engineering substance behind a demo that doesn't lie.
Upcoming
What Firm Memory will not do.
The negative claims as a manifesto.
§ 08 — Working session
008 / 008
Leave with a working diagnostic.
We come prepared. You leave with a written diagnostic of where FirmMemory pays back, and whether we're the right partner.
