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.
