Background

Harvey, a legal tech startup, has experienced rapid growth since its founding in 2022 and is currently worth $5 billion following the recent funding round. The company provides legal AI solutions to the broader legal community, assisting law firms and corporate legal departments in streamlining activities such as document review and legal research.

Harvey was established in 2018 as the brainchild of Winston Weinberg, a former junior lawyer, and Gabe Pereyra, a former DeepMind scientist, and was originally an exclusively invite-only service that now provides its services to over 500 clients, including large firms and companies like KKR and Bridgewater Associates. The company assists in the automation of time-consuming work, and the lawyers are able to be preoccupied with the complex legal work.

Harvey gained early traction when top law firm A&O Shearman became its first customer. Investors like OpenAI, Sequoia, and Google Ventures back the firm, drawn by its early market entry and strong technology focus.

The startup charges customers an average of several hundred dollars per user per month and emphasizes its legal-specific design, bulk document uploading, and enterprise security as key differentiators from general-purpose tools like ChatGPT.

Harvey is expanding globally, opening offices in Australia this month and in Toronto in October. Future plans include locations in Germany and India. The company recently partnered with LexisNexis to develop tools for creating legal arguments, such as motions to dismiss.

Weinberg says the goal is to grow fast without “breaking things,” balancing innovation with stability. He also seeks to break the conventional billable-hour paradigm and switch most of the tasks to fixed fees.

Harvey is among the very few AI startups that are effectively being incorporated into big law firms to transform the delivery of legal services as the competition intensifies with competitors such as Luminance, Legora, and Noxtua.
