Harvey

Harvey is a legal AI company whose platform is sold to law firms and in-house legal departments. LawNext reports that Gabriel Pereyra, who had worked on AI research at Meta and Google, and Winston Weinberg, a first-year litigation associate at O’Melveny & Myers, started it in 2022 as roommates in a San Francisco apartment.⁶ Its breakthrough, in that account, was Allen & Overy becoming “their first major client”;⁶ on February 15, 2023 the firm announced that more than 3,500 of its lawyers across 43 offices would use Harvey, for contract analysis, due diligence, litigation and regulatory compliance. The same announcement says Harvey received seed funding from the OpenAI Startup Fund and that its output “needs careful review by an A&O lawyer”.⁵

Harvey’s homepage now lists Agents, Vault for bulk document analysis, Knowledge for legal, regulatory and tax research, Spaces for shared workspaces with ethical walls, Command Center for usage analytics, Contract Intelligence, Horizon Scanning for regulatory changes, Intake for in-house requests, a Connector Library and Legal Work Orchestration. It names litigation and transactional work as practice areas, and lists SOC 2 Type II, ISO 27001 and ISO 42001 among its certifications.¹ Its June 1, 2026 use-case guide describes the work by role: transactional lawyers drafting and reviewing deals, litigators researching and drafting briefs, and in-house teams reviewing contracts against playbooks. Neither page maps a product to a job title such as associate or paralegal.¹² Harvey’s 2025 post on its agents says they leave “only review and finalization to the end user”.³

Harvey’s own scale figures differ by page: 3,500+ legal organizations and 200,000+ professionals on the homepage, against “more than 142,000 lawyers across 1,500+ organizations in 60 countries” in the June 2026 guide (both vendor-stated).¹² For operators, Nelson Mullins announced on August 24, 2026 that it is deploying Harvey across all its practice groups, a firm of more than 1,300 attorneys, policy advisors and other legal professionals.⁴ MetaRoles grades Harvey in production for lawyers' research and drafting on the strength of those operator announcements, and covers it in Harvey and six other legal AI platforms and AI legal research and lawyers: what the court records show, which also records what happens when AI-generated citations go unchecked.
