Case Study
Humphries Kerstetter
and Crimson
How one of London's leading disputes boutiques uses Crimson to interrogate case files, build chronologies, draft work product and manage correspondence across complex disputes.
About Humphries Kerstetter
Leading specialist disputes firm
Humphries Kerstetter is one of London's leading disputes boutiques. The firm handles some of the most complex domestic and international disputes, with recognised strength in commercial litigation, international arbitration, banking litigation and group litigation.
HK has entered into a firm-wide partnership with Crimson, giving its disputes lawyers access to a case intelligence platform built specifically around litigation and arbitration work. Crimson helps HK's teams find key documents, identify important dates and factual points, draft work product grounded in the evidence and analyse correspondence across the case file.
The Challenge
Complex disputes require fast, accurate command of the factual record
HK's lawyers work on complex, document-heavy disputes where understanding the factual record quickly and accurately is critical. Case teams need to interrogate pleadings, correspondence, witness evidence, expert reports, procedural materials, disclosure and hearing documents, often under significant time pressure.
The firm was looking for an AI platform tailored to the way litigators and arbitration lawyers actually work: one that could sit on top of the case file, understand matter-specific materials and support the practical tasks that drive dispute resolution.
Why Crimson was selected: Crimson is built specifically for disputes teams and designed to help lawyers move from large volumes of material to case-specific answers, analysis and work product. Unlike general-purpose AI tools, Crimson understands the structure and workflows of litigation and arbitration.
Crimson in practice
How Humphries Kerstetter wins cases with Crimson
Finding key documents and factual points
HK lawyers use Crimson to ask matter-specific questions across the case file, locate relevant documents and identify factual points that would otherwise require manual searches across folders, PDFs and correspondence. This is particularly useful when lawyers need to get up to speed quickly, prepare for calls with clients or counsel, or revisit a point that arose earlier in the matter.
“Crimson has become a very useful way of interrogating the case file. In document-heavy complex disputes, critical information can often be buried in a mass of material. Crimson helps us get to the relevant documents and factual points much faster and in a more cost-effective way enabling the team to focus on what those materials mean for the case.”
— Robert Javin-Fisher, Partner
Building chronologies and identifying key dates
HK uses Crimson to extract dates, events and related documents from case materials. This helps lawyers develop chronologies more quickly, spot gaps in the evidence and prepare clearer factual analyses for clients, counsel and internal strategy discussions.
“For disputes teams, a good chronology is often the foundation for the case strategy. Crimson helps us get there faster by identifying the key events across the documents and linking them back to the evidence.”
— Chris Louth, Counsel
Drafting support grounded in the record
HK uses Crimson to support drafting tasks such as first-pass factual summaries, issue notes, attendance notes, hearing preparation materials and sections of longer documents. Because Crimson sits on top of the case file, the output can be checked back to the underlying materials.
“Crimson is particularly helpful when drafting from a large case file. It helps us work across pleadings, correspondence, disclosure documents and witness evidence to identify the key material and produce drafts that can be checked against the underlying documents.”
— Sinead O'Brien, Managing Associate
Managing correspondence-heavy matters
On correspondence-heavy disputes, Crimson helps the team identify email chains, attachments, procedural communications and relevant exchanges. Through Crimson's Outlook integration, case teams can keep correspondence analysis connected to the wider case file.
“Crimson makes it much easier to stay on top of all relevant correspondence with its combination of Outlook syncing and the ability to search across the whole file. If we need to track how a party's position has shifted, find a specific quote, or check whether certain information has already been provided in emails across several months, we can do this in seconds.”
— Jon Dunne, Associate
Working across the full case file
Crimson's integrations with Outlook and OneDrive / SharePoint help HK bring key matter materials into one case-aware platform. Lawyers can analyse documents, correspondence and attachments together, rather than treating each source as a separate repository.

Firm-Wide Partnership
Core infrastructure for disputes work
HK's partnership with Crimson makes the platform available across the firm, supporting lawyers at every level of seniority and across different types of disputes. The firm-wide rollout reflects Crimson's role as core infrastructure for disputes work rather than an isolated point solution for individual matters.
“As we are a firm specialising in complex disputes, rolling Crimson out across the firm has made it part of the core infrastructure for everything we do. It gives every team member a single environment to interrogate the evidence and prepare work product more efficiently, which translates directly into better service for our clients.”
— Eraldo d'Atri, Partner
