San Francisco-based legal AI startup Harvey has closed $150 million in a Series F funding round led by Andreessen Horowitz, raising its valuation to over $8 billion, more than doubling its worth within four months. This is the third major funding round for Harvey in 2025 alone.
Founded in 2022 by Winston Weinberg, a former junior lawyer at O’Melveny & Myers, and Gabe Pereyra, a former DeepMind researcher, Harvey has rapidly expanded its footprint in the legal industry with a mission to automate and streamline complex legal workflows using generative AI. The startup has raised over $1 billion in total, outpacing many of its rivals on both fundraising scale and valuation within just three years.
Harvey’s AI system is built around custom large language models that truly understand the needs of law firms and in-house legal teams. Rather than having just a generic chatbot, it acts like a knowledgeable assistant that helps lawyers with the hard parts like conducting research, reviewing contracts, and drafting documents, so legal teams can work faster and with greater accuracy.
The company’s name and branding draw inspiration from Harvey Specter, the sharp and confident lawyer from the TV show Suits. This reflects Harvey’s ambition to empower lawyers with AI tools that feel like trusted partners.
Market Presence
Harvey’s client portfolio includes top-tier global law firms such as Allen & Overy, Shearman & Sterling, Ashurst, and corporate clients in investment management like KKR and Bridgewater Associates. The company claims to serve 337 legal clients worldwide with key individuals in over 40 leading law firms relying on its platform.
The startup also boasts more than 350 employees as of mid-2025, a rapid increase from 82 employees reported in early 2024. Its international footprint spans 53 countries, reflecting aggressive expansion plans.
According to CEO Winston Weinberg, Harvey crossed $100 million in annual recurring revenue (ARR) by August 2025, more than doubling its revenue since February of that year when it was reported making around $50 million ARR.
The company’s growth was accelerated by a $300 million Series E round closed in June 2025 at a $5 billion valuation, co-led by Kleiner Perkins and Coatue. The new $150 million Series F round pushes the valuation even higher, underscoring the market’s appetite for legal AI innovation.
Harvey operates in a crowded and fast-evolving legal tech space. Competitors include Swedish startup Legora (valued at roughly $1.8 billion and targeting Big Law clients), as well as established players like Luminance, Clio, Ironclad, and Casetext (acquired by Thomson Reuters in 2024).
Despite this competition, Harvey seeks to differentiate itself through deep collaboration between lawyers and engineers on its product development team. The company employs numerous lawyers from top-tier law firms who contribute domain expertise, guiding AI model refinement and workflow design.
Partnerships and Execution
Harvey has forged a deal with LexisNexis, the legal research giant owned by RELX, in June 2025. This signals integration ambitions with leading legal databases. RELX’s venture capital arm, REV, is also an investor in Harvey.
The company was named to Forbes’ AI 50 list of promising startups in 2023 and featured in Forbes’ Next Billion-Dollar Startups list. Co-founder Winston Weinberg was honored on the 2024 Under 30 Enterprise Technology list, highlighting his leadership in both AI and legal innovation.
CEO Winston Weinberg’s experience as a junior lawyer boosts Harvey’s vision for solving real legal workflow pain points. He emphasizes tailored AI solutions that understand legal context rather than generic chatbot interactions.
Gabe Pereyra, co-founder and CTO, brings cutting-edge research expertise from DeepMind with a focus on developing high-performance large language models optimized for legal use cases. Their complementary backgrounds ensure Harvey blends commercial insight, legal domain knowledge, and technical innovation.
Harvey plans to use its latest $150 million infusion to accelerate product development, expand international reach, and grow its workforce in engineering, AI research, and customer success teams.
The startup aims to continue pushing innovative AI tools that enhance lawyer productivity, reduce costs, and streamline contract management and litigation processes.
Harvey’s AI-driven tools offer both speed and precision, turning what used to be tedious tasks into automated, streamlined workflows. The latest funding round not only shows Harvey’s growth but also signals a bigger transformation in the legal industry.
