Harvey AI Adds Box Integration Amid Push for $11B Valuation

Harvey AI has launched a direct integration with Box, allowing legal teams to analyze documents stored in the cloud platform without downloading local copies. The move addresses a persistent pain point in legal tech: the security risks that come with duplicating sensitive client files.

The integration arrives as Harvey reportedly pursues a $200 million funding round at an $11 billion valuation, according to February 2026 reports. That would mark a significant jump from the company's $8 billion valuation in December 2025.

What the Integration Actually Does

Legal professionals can now pull documents directly from Box into Harvey's Assistant, Workflow agents, and Vault features. The practical applications break down into three main categories: due diligence reviews for M&A transactions, litigation prep involving discovery materials, and compliance work requiring policy analysis.

The security angle matters here. Law firms handling client documents face strict data governance requirements. By working with files in place rather than creating copies, the integration lets organizations maintain existing access controls. Harvey only touches files users explicitly select—no blanket access to entire Box repositories.

Harvey's Aggressive Expansion

This Box partnership fits a broader pattern. On March 16, Harvey announced a customer advisory board featuring the CLO of HSBC Holdings. The same week, the company revealed plans for a Singapore office to serve Asia-Pacific clients.

The legal AI startup has built its business on large enterprise contracts, reportedly maintaining high minimum deal values that price out smaller firms. That strategy appears to be working—Harvey's annual recurring revenue hit $190 million by the end of 2025.

Founded in 2022 by Winston Weinberg and Gabriel Pereyra, Harvey uses fine-tuned large language models trained on legal data, statutes, and case law. The company leverages models from OpenAI, Anthropic, and Google.

Market Implications

For Box, the partnership reinforces its position as the document management layer for regulated industries. For Harvey, it's about reducing friction in enterprise sales—legal teams already using Box face one less obstacle to adoption.

The integration is live now for existing Harvey customers. Given the company's trajectory toward that $11 billion target, expect more platform partnerships designed to embed Harvey deeper into law firm workflows.
