Harvey is the leading generative AI platform for enterprise law firms and in-house legal teams, combining domain-specific AI models trained on legal data with a comprehensive suite of legal workflow applications. The platform is used by the majority of Am Law 100 firms and is widely considered the benchmark for enterprise legal AI.
Harvey's platform covers four core surfaces: Assistant for research and drafting, Vault for bulk document analysis on due diligence and compliance review, Knowledge for firm-specific document access, and Workflow Agents for multi-step automation. The Vault capability is particularly differentiated — allowing legal teams to process thousands of documents simultaneously against a consistent analytical framework.
The platform raised a $300 million Series E at a $3 billion valuation in February 2025, led by Sequoia Capital, reflecting extraordinary investor confidence in Harvey's market position. With over 500 in-house legal teams and the majority of top US law firms as customers, Harvey has established a dominant position in the enterprise legal AI market.
Harvey's security architecture — SOC 2 Type II, no training on customer data, and enterprise data isolation — addresses the confidentiality requirements that are non-negotiable for law firm adoption. The platform's integration with iManage, NetDocuments, and other document management systems enables deployment within existing law firm workflows.
