Harvey is an AI software company founded in 2022 by Winston Weinberg and Gabriel Pereyra, headquartered in San Francisco, California. The company develops AI-powered tools tailored for legal and professional services firms, including law firms, consulting firms, and accounting practices.
Harvey's platform provides capabilities including legal research, contract review, due diligence, regulatory analysis, and document drafting. The company counts several of the largest global law firms among its customers, including Allen & Overy, PwC, and Skadden. Its products are built on large language models and are designed to integrate into existing legal workflows.
Harvey raised a $21 million Series A in 2023, followed by a $100 million Series B later that year led by Sequoia Capital, and a $300 million Series C in 2024 at a reported valuation of approximately $3 billion. The company also secured additional funding in early 2025, bringing total disclosed funding to approximately $494 million. As of 2024, the company employed several hundred people.

Who Harvey competes with, and how they differ.
Legora sells an "agentic operating system" spanning both law firms and in-house teams across practice areas like M&A and litigation, competing directly for the same BigLaw customer base with a similar generative-AI-for-lawyers pitch and a collaboration-over-automation message.
1 product reviewed on TopReviewedThomson Reuters bundles its CoCounsel assistant (built from its Casetext acquisition) with the incumbent Westlaw research database and Practical Law content, competing on existing law-firm distribution rather than a standalone AI-native product like Harvey's.
5 products reviewed on TopReviewedRobin AI focuses narrowly on contract review and management for enterprise in-house legal teams rather than Harvey's broader litigation, research and drafting scope, and is backed by Google, Temasek and PayPal rather than an OpenAI/Anthropic-aligned cap table.
LexisNexis competes with its own Protege AI research assistant built on its case-law database and Shepard's Citations, even as the two companies struck a June 2025 content-licensing alliance letting Harvey draw on LexisNexis data — a partner in some workflows, a rival in AI-assisted legal research generally.
