Harvey, an AI software developer for legal professionals, raised $300 million in Series E funding led by Kleiner Perkins and Coatue, valuing the company at $5 billion.
Harvey's AI tools aim to boost productivity for legal teams, with its platform used by over 330 law firms and generating $75 million in revenue annually.
Its flagship AI tool, Harvey Assistant, helps automate legal document drafting, reviews drafts against internal guidelines, proofreads, translates, and auto-fills contract fields.
Harvey's redlining feature automates summarizing document changes, leveraging a custom AI model with about 100,000 parameters and neural network architecture.
The company uses off-the-shelf language models and plans to incorporate AI models from LexisNexis post-funding.
Proceeds from the investment will double Harvey's workforce and support expansion into new market segments beyond law.
Harvey's technology involves turning PDF contracts into images and applying filters before inputting into AI models to enhance accuracy and inference speed.
