Kirkland Partners With Syllo For Secret Sauce Litigation.

Kirkland Partners With Syllo For Secret Sauce Litigation. 29th June 2026 artificiallawyer Secret Sauce Comments Off on Kirkland Partners With Syllo For Secret Sauce Litigation Fresh from signing a massive deal with Palantir and going on a legal AI hiring spree, Kirkland & Ellis has inked a deal with Syllo, a 'unified platform for litigation case management, eDiscovery, legal research, analysis and drafting' that will also allow the firm to build its own skills into the system. The multiyear strategic partnership 'marks a defining step in Kirkland's litigation AI strategy and gives Kirkland the exclusive ability to build proprietary solutions within and around the Syllo AI platform, which Kirkland selected for rollout across its litigation practice following a multiyear evaluation of the market'. As with the Palantir deal, Kirkland is very much sending out a message that this is all about its own 'secret sauce' and the bottling process for that. In this case, rather than PE, it's all about litigation. Kirkland plans to build on Syllo's foundation through a 'unique set of rights to develop proprietary AI solutions and knowledge infrastructure that extend and interconnect with the platform. This arrangement is exclusive to Kirkland for an extended period', they added. Andrew Kassof, who leads Kirkland's litigation practice as a member of the firm's Executive Committee, commented: 'Syllo's platform and our exclusive custom-build rights will allow us to bring our most senior judgment and proprietary know-how to bear in our development and deployment of litigation AI, delivering strategic advantages, differentiated service, greater efficiencies and better results for our clients across the lifecycle of litigation' Elizabeth Hess, litigation partner and member of Kirkland's Executive Committee, added: 'Syllo is different from anything else in the market. Its platform, knowledge infrastructure and agentic solutions for litigation are decisively ahead of every other solution we evaluated over an extended period. 'More importantly, we're excited about our ability to extend those capabilities through custom development that captures Kirkland's distinctive knowledge and institutional experience.' Jeffrey Chivers, CEO and head of product at Syllo, concluded: 'We built the Syllo platform and Litigation Agent to augment and amplify attorney capabilities. Kirkland's decision to build on Syllo reflects the depth and unique strengths of our platform, which powers the work of our clients across the market every day. We are proud to support the next chapter of litigation at Kirkland, and the litigators everywhere who rely on Syllo.' Is this a big deal? Well, K&E are certainly making waves, and as noted, it's all about the sauce - the secret kind. Some of what Syllo offers: 'Case management re-imagined 01. Dynamic Chronologies & Narrative Building Construct your case story by combining attorney expertise with AI-powered insights.
