Partners now make up 23% of Harvey's law firm users, up more than 4x

Partners drive usage down the ranks

Harvey, which sells AI tools to law firms, drew on data from its "hundreds of thousands of users" to describe how adoption is changing. The company says the number of users who are partners is more than 4x what it was a year ago, and that partners now make up 23% of its law firm users, nearly a quarter.

According to Harvey, partner behavior influences the rest of the firm. Associate utilization rates were 25 points higher when partner utilization was in the top quartile. For that reason, the company encourages partners to join its adoption workshops and training for rollout planning.

Harvey also advises firms to involve partners who took part in a pilot. It describes a firm that asked whether pilot partners could share examples and use cases during a firm-wide rollout, and says that is not only welcome but encouraged.

Corporate leads on query volume, litigation grows fast

Among its law firm customers, Corporate work, including M&A, has the highest query volume, followed by Litigation, Banking & Finance, and Real Estate. Harvey says part of this reflects early adopters and the transaction volume tied to their work, as well as how much value partners see in AI and how they set an example for their teams.

The fastest growing practice groups by query volume are Litigation, Real Estate, Intellectual Property, and Family Law. Harvey data from June points to due diligence and deal management as common uses for corporate attorneys. In litigation, the company sees case management, regulatory and advisory analysis, discovery and trial preparation.

Across agents, the most common tasks are drafting, analysis and review, and extracting information from documents. Harvey also mentions employment lawyers using its agentic capabilities and horizon scanning to help lawyers prepare for legal and regulatory changes.

In its SMB and Mid-Market segments, more than half of weekly active users use knowledge sources and more than 40% use Vault. Harvey suggests firms include these features in training alongside drafting.

Growth across more than 85 countries

Harvey says it serves customers in more than 85 countries and that adoption is up significantly across the board. Markets that stand out for year-over-year growth in monthly active users include Brazil, Israel, Italy, Mexico (roughly 4x), New Zealand, South Korea (nearly 12x), and the United States.

The United States and the United Kingdom remain among its largest markets by users, followed by Germany and Australia. The company also points to the role of local context: at Vinge, lawyers use Harvey to adapt their advice to the tone and terminology of EU regulatory work. Harvey says language specificity, practice area relevance and time in the product can drive lasting adoption.

What it means for firms planning a rollout

Harvey concludes that legal AI is no longer a tool only for junior associates, nor limited to drafting or a single practice area. Its advice to firms is to bring pilot partners into the rollout, ask them to share the use cases they found most valuable, and use those examples to shape training for each practice and local legal context.

As rollout progresses, the company recommends looking at usage by seniority and practice area to see where adoption is taking hold, and asking teams where they need more support. The figures come from Harvey's own platform and are presented by the company, so they reflect its customer base rather than the legal industry as a whole.
