Crimson, in brief.
Crimson is the litigation intelligence layer on top of your firm's existing systems, including iManage, NetDocuments, Outlook, SharePoint, and OneDrive. It supports the work that runs through every contentious matter, from the first call to the final hearing.
The Case Model
Crimson reads the full case file and builds a structured map of the claims, defenses, issues, facts, and evidence. Every answer and draft draws on that understanding, with each point cited to its source.
Chronologies and case analysis
Generate live chronologies spanning thousands of documents, compare the parties' positions, and test the strength of each issue in minutes. Teams spend their time on judgment rather than assembling the record.
Drafting and binders
Draft briefs and correspondence grounded in the record, and compile court-ready binders in seconds. Every reference points to the exact document, page, and paragraph.
Correspondence and deadlines
Crimson tracks correspondence between the parties and surfaces deadlines from orders and agreements as they arrive. Nothing material is lost in the inbox.
What makes Crimson different.
- 01
Designed for disputes
General-purpose legal AI assistants are designed to serve every practice area. Crimson is built solely for litigation, arbitration, and investigations, around the concepts litigators reason with.
- 02
A persistent understanding of the matter
Most AI tools start from scratch with every prompt. Crimson builds its understanding when documents are uploaded and keeps it current as the case evolves.
- 03
Every conclusion cited
Crimson cites every fact and inference to the document, page, and paragraph. Lawyers can verify any answer in seconds before they rely on it.
- 04
Built on your existing systems
Crimson connects to iManage, NetDocuments, Outlook, SharePoint, and OneDrive and works on top of them. There is no new repository to maintain and no change to how teams file documents.
- 05
Analysis, not first-level review
eDiscovery platforms are built for first-level review of large productions. Crimson works on the case file the team relies on and turns the documents that matter into analysis and work product.
- 06
Deployed by former litigators
Lawyers who have run complex disputes configure Crimson around each firm's matters and train its teams. They understand the work because they have done it.

Crimson is used on matters across the US, UK, Europe, the Middle East, and Asia Pacific.

The team behind Crimson.
Mark Feldner and David Strömbäck founded Crimson in 2024 because generic AI does not understand the factual, procedural, and strategic context of a complex dispute. Today our former litigators and engineers work together from London and New York.
How Crimson works.
Former litigators lead every deployment, shaped around your firm's matters, systems, and security requirements.
