Harvey and DeepJudge Join Forces to Boost Legal AI

Harvey and DeepJudge partnered on May 20, 2026, in New York to bring institutional knowledge directly into AI-powered legal work.

The two companies are addressing a gap that limits most legal AI tools today: the inability to apply a firm's own past work, decisions, and expertise in real time. Law firms and in-house legal teams have spent decades building knowledge, but that knowledge often sits fragmented across documents, matters, and teams. This partnership directly targets that problem.

The Core Problem

Most legal teams hold years of institutional knowledge across memos, contracts, negotiated positions, and prior matters. That knowledge is rarely accessible when it is needed most.

DeepJudge calls this the "context tax." It refers to the productivity lost when AI tools lack the context of how a specific legal team actually works. Even well-built AI systems fall short when they cannot draw on a firm's unique standards and judgment.

How the Partnership Works

Harvey provides AI-powered workflows for tasks including contract analysis, due diligence, compliance, and litigation. DeepJudge adds a layer of institutional intelligence on top of those workflows.

When a lawyer drafts a document in Harvey, DeepJudge surfaces relevant prior work, accepted language, and past positions from within that firm's knowledge base. Work produced in Harvey is then reflected back into DeepJudge, so every completed matter feeds into the organization's growing knowledge pool.

The system respects existing access permissions and ethical walls within firms, ensuring that sensitive matter information is only surfaced to those authorized to access it.

Paulina Grnarova, CEO and co-founder of DeepJudge, described the combined offering this way: "DeepJudge brings past work, decisions, and institutional expertise directly into that reasoning, so that the resulting work reflects the judgment, standards, and ways of working unique to each firm or legal department."

Winston Weinberg, CEO and co-founder of Harvey, pointed to the gap the partnership closes: "Most firms have decades of expertise embedded across prior work and decisions, but that knowledge is often fragmented and difficult to apply consistently in practice. This partnership closes that gap by bringing a firm's institutional knowledge directly to Harvey users."

Early Adoption

Holland and Knight, a major law firm, is already using the combined platform. Martin Durkin, a partner at the firm, said the pairing helps every document reflect what is accepted within the firm. Harvey accelerates the work, while DeepJudge grounds the output in the firm's own experience and judgment.

Harvey currently serves more than 1,500 customers across 60 or more countries. The company is backed by investors including Sequoia, Kleiner Perkins, GV, OpenAI Startup Fund, Coatue, Andreessen Horowitz, GIC, and EQT. DeepJudge, founded by former Google researchers with PhDs in AI from ETH Zurich, is backed by Coatue and Felicis, and operates across North America and Europe.
