Addleshaw Goddard to Deploy Harvey Firmwide and Co-Develop Legal AI
Add Unite.AI to your preferred sources on Google
London-headquartered Addleshaw Goddard will provide Harvey’s legal AI platform to more than 3,400 lawyers and business services professionals across Europe, the Middle East and Asia from January, alongside a co-development program covering legal work and client delivery, Harvey announced on November 9, 2026.
Addleshaw Goddard’s Innovation Group will work directly with Harvey’s product and legal engineering teams. Lawyers, business services professionals and clients will help shape and test priority capabilities, establish consistent adoption practices and develop new AI-enabled services, making product feedback and client involvement part of the rollout itself.
Assessment Informed the Platform Choice
Addleshaw Goddard said the collaboration followed a three-month assessment led by its 80-person Innovation Group, which drew on a decade of experience developing and deploying AI and legal technology. During the assessment, 400 partners, lawyers, legal technologists and business services professionals tested leading platforms on real legal and business tasks.
From the outset, AG practitioners worked with Harvey’s product and legal engineering teams to test emerging capabilities and provide detailed feedback on complex legal work and delivery at pace and scale. Managing Partner Andrew Johnston described the agreement as the firm’s most significant technology transformation and said the co-development element takes it beyond a firmwide deployment.
Review Tables Offer an Early Co-Development Example
The announcement presents Review Tables as an early result of that work. Harvey’s product team and AG’s Innovation Group further developed the feature, which helps lawyers organize, compare and verify large volumes of information on complex matters. AG’s feedback shaped source checking, preservation of lawyer-reviewed work, sharing and performance, and the firm received early access to AI-led features for creating and updating tables at scale.
A Harvey engineering post published October 22, 2026 explains the underlying workflow. Lawyers can ask natural-language questions across uploaded documents, with rows representing individual documents and columns mapping to questions. Each answer cell includes the model’s reasoning and citations from the source document, allowing reviewers to inspect the material behind an answer.
Rows can be assigned to collaborators, answers verified or locked, and comments added for discussion. Once verified, a table can serve as a reusable, validated source for a later memo or presentation. Those controls let large teams divide review work and retain checked answers instead of recreating the analysis.
Scale has also imposed an engineering constraint. Harvey engineers said loading complete tables in the browser caused lag and, in the largest cases, failures after tables exceeded thousands of rows. Their redesign fetches ordered rows page by page while preserving sorting and filtering, so a large table no longer has to load every row into the browser at once.
Clients and Governance Are Part of the Rollout
Addleshaw Goddard and Harvey plan to meet quarterly with selected clients to identify shared challenges, explore new approaches to legal service delivery and, where appropriate, co-create solutions. The sessions extend the collaboration beyond internal adoption by bringing client requirements into the same co-development model.
Kerry Westland, partner and head of the Innovation Group, described the agreement as a decisive next step in the firm’s buy-and-build AI approach. She identified better outcomes, greater quality and consistency, increased capacity and new ways of working with clients as opportunities, while emphasizing that “human judgement, supervision and accountability” should remain central.
The collaboration also sits within AG2030, the firm’s international growth strategy, in which innovation is a central component. Its practical test is to turn co-development and client input into consistent legal services across the workforce while preserving the professional oversight Westland described.
