Legal AI startup Harvey is in advanced talks to raise at least $500 million at a $15.5 billion valuation, just five months after investors valued the four-year-old company at $11 billion, according to an exclusive report from The Information.
The proposed deal would mark a 40% valuation jump in less than half a year. There is something behind the eye-popping number: Harvey’s revenue has been climbing at nearly the same breakneck pace.
The San Francisco startup is now generating more than $350 million in annualized revenue, according to a person familiar with the fundraising cited by The Information. About $300 million of that is annual recurring revenue, up from roughly $190 million ARR at the end of 2025.
“Legal AI startup Harvey is in talks to raise at least $500 million at a $15.5 billion valuation, including the investment, a 40% premium to its last valuation five months ago. The fundraising follows a revenue surge at the legal AI startup, according to a person with knowledge of the fundraise,” The Information reported.
Lightspeed Venture Partners has expressed interest in leading the new financing. The talks are ongoing, and the final terms could still change.
A deal at the proposed size would take Harvey’s total funding beyond $1.7 billion. The company has already raised more than $1.2 billion from a roster of prominent investors that includes Sequoia Capital, Andreessen Horowitz, GIC, Coatue, Kleiner Perkins, Conviction and Elad Gil.
Harvey’s $3 Billion to $15.5 Billion Climb
Few vertical AI startups have seen their valuations rise this quickly.
Harvey was valued at $3 billion in February 2025, followed by $5 billion in June. An Andreessen Horowitz-led financing pushed that figure to $8 billion in December. By March 2026, Harvey had reached a $11 billion valuation after raising another $200 million in a round co-led by Sequoia and Singapore’s GIC.
A $15.5 billion deal would mean Harvey’s valuation has increased more than fivefold in roughly 18 months.
Founded in 2022 by former O’Melveny & Myers litigator Winston Weinberg and former Google DeepMind and Meta researcher Gabe Pereyra, Harvey emerged from experiments the pair conducted with early versions of GPT-3.
They saw an opening in one of the most expensive corners of knowledge work: law.
Harvey built AI software that helps lawyers with legal research, document review, contract analysis, due diligence and compliance work. Its platform has since moved deeper into multi-step legal workflows through custom AI agents.

The strategy appears to have found a large audience. Harvey says more than 100,000 lawyers across 1,300 organizations use its software. Its customers include Latham & Watkins, A&O Shearman and O’Melveny, along with corporate legal teams at companies such as Comcast and Verizon. More than 25,000 custom AI agents have been created inside customer organizations, according to the company.
That adoption helps explain why investors continue writing increasingly large checks.
Harvey’s reported ARR stood near $100 million in 2025 before reaching $190 million around the start of 2026. At roughly $300 million today, the company has added about $110 million in recurring revenue in a matter of months.
The numbers matter for another reason. Investors have spent much of the generative AI boom pouring billions into foundation-model companies such as OpenAI and Anthropic. Harvey represents a different bet: that enormous companies can be built one layer above the models by applying AI to expensive, specialized work.
Legal services may be particularly suited to that thesis. Lawyers spend huge amounts of time reading, searching, comparing, and producing text, creating a natural market for language models that can operate within professional workflows.
Competition is growing. Legal technology companies including Clio and Relativity are building their own AI capabilities, and newer startups such as Sweden’s Legora are chasing the same opportunity.
Harvey’s head start with major law firms has made it one of the companies to beat.
The proposed valuation comes at a steep price. At $15.5 billion against more than $350 million in annualized revenue, Harvey would be valued at roughly 44 times revenue. That would be extraordinary by traditional software standards.
Investors appear willing to make that bet as long as Harvey keeps turning AI adoption into recurring revenue at its current pace.
If the round closes near the terms being discussed, Harvey will have traveled from a $3 billion valuation to $15.5 billion in about a year and a half.
For all the giant numbers surrounding the AI boom, that may be the number worth watching.
