Harvey

Founded in 2022 and valued at $11 billion as of a March 2026 funding round that raised $200 million, Harvey has become the dominant AI platform in the legal technology market, with a client list that includes the world's largest law firms and Fortune 500 legal departments.

Harvey's core capabilities address the most time-intensive work in legal practice: contract review and analysis, due diligence for M&A transactions, litigation research and brief drafting, regulatory compliance monitoring, and complex legal question answering across jurisdictions.

Unlike general-purpose AI assistants that lack legal training data and hallucinate citations, Harvey is trained on legal-specific corpora case law, statutes, legal filings, and transactional documents and is designed to work with confidentiality and precision requirements that legal professionals demand.

The platform's agentic capabilities have evolved significantly: Harvey can run pre-built workflow agents that automate complete legal processes a due diligence agent might review hundreds of documents across a data room, extract key provisions, identify risk flags, and produce a structured summary report without step-by-step human guidance at each stage.

Firms can also build custom agents tailored to their practice-specific workflows and preferred analytical frameworks, embedding institutional knowledge into Harvey's automated processes.

Harvey integrates with Microsoft 365 Copilot, bringing legal AI assistance directly into Word, Outlook, and Teams the environments where most legal drafting and communication actually happen.

The platform's enterprise security architecture includes SAML SSO, audit logs, IP allow-listing, and granular data lifecycle management, meeting the strict security requirements of law firm information governance policies.
