Specialist disputes boutique, London
Humphries Kerstetter is one of London's leading disputes boutiques, with recognized strength in commercial litigation, international arbitration, banking litigation and group litigation. The firm has entered into a firm-wide partnership with Crimson.
“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-FisherPartner, Humphries Kerstetter
Global law firm · Fuse innovation program
Since Crimson joined A&O Shearman's Fuse technology program in May 2025, direct engagement with lawyers across the firm's litigation, arbitration and investigations practices in London and New York has shaped the platform.
That engagement has helped Crimson develop to the standard Magic Circle and Am Law 10 firms require: large volumes of documents, multiple jurisdictions, tight deadlines and work product that has to be right.
“From its user interface and integrations to case-specific outputs, Crimson is well designed for complex litigation and arbitration.”
Maeve HannaPartner, A&O Shearman
