Addleshaw Goddard and Harvey launch firmwide collaboration to shape AI-enabled legal delivery

Addleshaw Goddard (AG), the London-headquartered international law firm, has formed a firmwide collaboration with Harvey, the market-leading legal AI platform, to combine deployment at scale with an ongoing programme of AI co-development focused on legal work and client delivery.

From January, AG will provide Harvey to its entire workforce of more than 3,400 lawyers and business services professionals across Europe, the Middle East and Asia. AG’s Innovation Group will work directly with Harvey’s product and legal engineering teams, bringing together the firm’s lawyers, business services professionals and clients to shape and test priority capabilities, develop practical, consistent ways of working for adoption across the firm, and create new AI-enabled services.

Andrew Johnston, Managing Partner of Addleshaw Goddard, says:

“This is a unique partnership with Harvey to co-develop legal AI solutions, and the most significant technology transformation in AG’s long history as an innovator. It goes well beyond a firmwide deployment as we will work with Harvey to shape legal AI around the demands of complex legal work and the needs of our clients.

“Having thoroughly assessed the market, this partnership with Harvey is the right next step at the right time in our AI evolution, creating new opportunities for our clients, our people and our business. This major milestone underlines our distinctive approach to innovation.”

The collaboration with Harvey follows a rigorous three-month assessment led by AG’s 80-strong Innovation Group, drawing on a decade’s experience of developing and deploying AI and legal technology. 400 AG partners, lawyers, legal technologists and business services professionals tested leading platforms on real legal and business tasks. From the outset, AG practitioners worked directly with Harvey’s product and legal engineering teams to test emerging capabilities and provide detailed feedback on the demands of complex legal work and delivery at pace and scale.

Winston Weinberg, CEO and co-founder of Harvey, comments:

“We’re proud to collaborate with a firm as innovative as Addleshaw Goddard. AG has been an AI leader for years. Now we’re working together to bring Harvey to its 3,300+ professionals and shape what comes next. Together, we’ll build on AG’s track record of delivering high-quality outcomes for clients globally.”

The collaboration is already producing tangible results. Drawing on AG teams’ experience of complex, large-scale matters, Harvey’s product team worked with the Innovation Group to further develop Review Tables, which help lawyers organise, compare and verify large volumes of information. These capabilities are critical on the firm’s most demanding matters, where large teams need to analyse material accurately, consistently and at speed. AG’s feedback shaped improvements to source checking, preserving work already reviewed by lawyers, sharing and performance, and the firm gained early access to AI-led features for creating and updating tables at scale.

AG and Harvey plan to convene quarterly with selected clients. The sessions will identify shared challenges, explore new approaches to legal service delivery and, where appropriate, co-create solutions.

Kerry Westland, Partner and Head of the Innovation Group at Addleshaw Goddard, adds:

“We have used AI consistently and effectively for a number of years through our buy-and-build approach. This is a decisive next step, but it is not simply a technology rollout. By combining the experience of our lawyers, legal technologists and business services professionals with Harvey’s product and engineering capability, and involving clients directly, we can shape practical solutions around real legal work. The opportunity is to deliver better outcomes, greater quality and consistency, increased capacity and new ways of working with clients, while keeping human judgement, supervision and accountability at the centre.”

Innovation is at the heart of AG’s ambitious AG2030 international growth strategy. Addleshaw Goddard was recently ranked the second Most Innovative Law Firm in Europe and won the Innovative Lawyers in AI, Digital Regulation and Technology title at the prestigious FT Innovative Lawyers Europe Awards.

AG was named Law Firm of the Year at the 2026 Legal Business Awards in September, the fourth Law Firm of the Year title the firm has won at major legal awards programmes in little over two years.

Tomorrow, Tuesday 10 November, AG will publish a new report, Successful Tech Transformation in the Age of AI, based on research with 200 major organisations across a range of industry sectors.
