AI platform for legal and professional services that executes legal work end-to-end, including document analysis, research, drafting, and workflow automation.
Harvey is a premium enterprise AI platform purpose-built for the legal industry, falling in the Legal AI category alongside tools like Casetext and LexisNexis, with custom enterprise pricing estimated at $80â$300 per user per month depending on firm size and feature requirements â best suited for mid-sized to large law firms and in-house legal departments seeking end-to-end AI-powered legal workflow execution.
Founded in 2022 by Winston Weinberg (former antitrust associate at O'Melveny & Myers) and Gabriel Pereyra (former Google DeepMind research scientist), Harvey has raised over $500 million in venture funding as of early 2025, including a $300 million Series D at a reported $3 billion valuation. The company has secured backing from prominent investors including Sequoia Capital, Google Ventures, and the OpenAI Startup Fund. Harvey serves over 25,000 lawyers across major AmLaw 100 firms, Big Four professional services firms, and Fortune 500 in-house legal departments globally.
The platform is built around several core products that work together as a unified system. Harvey Assistant allows lawyers to ask questions, analyze documents, and draft content using domain-specific AI trained on legal reasoning. Harvey Vault provides secure document storage with the ability to organize and bulk-analyze large volumes of legal documents, which is particularly valuable for due diligence and litigation review. Harvey Knowledge enables complex legal, regulatory, and tax research across multiple domains, going beyond simple search to synthesize answers from authoritative sources.
A distinguishing feature of Harvey is its Workflow Agents system, which allows firms to run pre-built automation workflows or build custom agents tailored to their specific practice needs. These agents can handle multi-step legal tasks autonomously, from document review to research synthesis. Harvey also offers a mobile application for on-the-go access, enabling lawyers to stay productive outside the office.
Harvey's Ecosystem integration layer connects the platform to tools lawyers already use, grounding AI-generated answers in trusted sources. The platform emphasizes security, which is critical for legal work involving privileged and confidential information. Harvey also supports cross-organizational collaboration, allowing legal teams from different firms or departments to work together in secure shared spaces.
The platform targets multiple practice areas including transactional work (due diligence, contract analysis), litigation (case research, brief drafting, document review), and in-house legal operations (workflow streamlining, strategic focus). Harvey also specifically addresses mid-sized firms, offering tools designed for lean teams that need to punch above their weight. According to Harvey, firms using the platform have reported up to 10x faster document review times and an average of 4 hours saved per lawyer per week on routine research tasks.
Harvey provides an ROI calculator for both law firms and in-house teams, and offers Harvey Academy for on-demand training and workflow guidance. The company has grown to over 400 employees and operates offices in San Francisco and London. The platform operates on an enterprise pricing model, typically requiring a demo and custom pricing discussion rather than self-service signup.

Harvey's Workflow Agents allow firms to run pre-built automation workflows or create custom agents tailored to specific practice needs. These agents can execute multi-step legal tasks end-to-end, moving beyond simple question-and-answer interactions to handle complex processes like document review pipelines, compliance checks, and research synthesis. Firms can standardize best practices into repeatable workflows, ensuring consistency across matters and attorneys while significantly reducing time spent on routine procedural work.
Vault serves as a secure document repository with built-in AI analysis capabilities. Unlike basic document storage, Vault enables bulk analysis of large document sets, making it particularly valuable for due diligence, litigation document review, and regulatory compliance projects. Users can organize documents by matter, apply AI-powered analysis across entire collections, and extract insights that would take human reviewers significantly longer to identify manually. Security is baked into the architecture to protect privileged materials.
The Knowledge product goes beyond simple legal search by enabling complex research across legal, regulatory, and tax domains. Rather than returning a list of results, it synthesizes information from multiple authoritative sources to provide comprehensive answers to nuanced legal questions. This is especially valuable for cross-jurisdictional research, regulatory analysis, and tax planning where lawyers need to understand how multiple overlapping rules and precedents interact.
Harvey enables legal teams from different organizations to work together in secure shared spaces, supporting new collaborative service models between law firms, corporate clients, and professional service networks. This feature addresses the reality that legal work frequently involves multiple parties who need controlled access to shared documents and analysis. The secure collaboration framework maintains confidentiality boundaries while enabling the efficiency gains of shared AI-powered workspaces.
