Harvey, a San Francisco–based startup building generative AI tools for law firms and corporate legal teams, has completed a $150 million investment round led by Andreessen Horowitz, pushing its valuation to approximately $8 billion. The fresh capital reflects growing investor confidence in the legal-tech sector and signals a new wave of innovation for legal service automation.
TL;DR
Harvey, a legal-AI startup, has raised $150 million in a funding round led by Andreessen Horowitz, valuing the company at about $8 billion. The startup builds generative-AI tools to automate legal tasks for law firms and corporate legal teams, and will use the funds to expand globally, deepen its tech stack and accelerate enterprise adoption.
In a move that underscores the accelerating momentum behind legal-technology innovation, Harvey has raised $150 million in a new funding round led by Andreessen Horowitz, bringing the startup’s valuation to around $8 billion.
Found in 2022 by former litigator Winston Weinberg and research scientist Gabriel Pereyra, Harvey is focused on applying generative-AI models to legal workflows — aiming to automate tasks such as contract review, document drafting, case summarisation, and legal research. The injection of capital marks Harvey’s third major raise in 2025, and comes at a time of heightened interest in “legal-AI” solutions from both law firms and in-house legal teams seeking to improve efficiency amid rising cost pressures.
Why it matters: For the legal industry — often criticised for slow technology adoption — the backing of a well-known firm like Andreessen Horowitz signals that legal workflows can be modernised with AI in ways previously viewed as niche or experimental. Harvey’s elevated valuation reflects both its growth potential and the belief that legal-tech is entering a more mature phase of funding and scale.
What Harvey will do with the funds: The company plans to accelerate product development, expand enterprise integration, and support global expansion. The capital will also help Harvey deepen its technology stack and partner ecosystem so it can serve the demands of large law firms and corporate legal departments.
While Harvey holds a strong position, it operates in a busy field. Competitors in legal-tech and generative-AI for law include firms focusing on contract-lifecycle management, document automation, and AI-augmented legal research. As firms increasingly demand intelligent tools, winners will likely be those who deliver domain-specific expertise combined with enterprise-grade security and scalability.
Challenges
Despite the promising outlook, Harvey faces hurdles such as convincing conservative legal clients to adopt AI, proving its solutions across diverse legal jurisdictions and practice areas, and staying ahead of more general-purpose AI models that may encroach into legal workflows. Execution at scale will be critical.
Harvey’s new funding and valuation underscore a pivotal moment for legal technology — the AI tools once relegated to pilot projects are now entering the mainstream, and investors are betting big on the companies that help law firms work faster, smarter, and more cost-effectively.
