Legal AI rarely makes people stop and stare, yet Harvey has managed to pull some of the brightest investors in the Valley straight into its orbit. The company’s cap table reads like a Silicon Valley hall of fame, with the OpenAI Startup Fund stepping in first, followed by Sequoia Capital, Kleiner Perkins, Google Ventures, Coatue, Elad Gil, and most recently Andreessen Horowitz.

The numbers tell an even stronger story. Harvey’s valuation leaped from three billion dollars in February 2025 to five billion in June and then touched eight billion by late October. That kind of climb speaks to the overall hype around AI, but it also reflects something real: Harvey is winning the trust of major law firms and corporate legal teams at a pace no one predicted.

Scaling Across The Legal World

Harvey now says it serves seven hundred clients across sixty-three countries. Most of the top ten United States law firms are already onboard. By August, the company crossed one hundred million dollars in annual recurring revenue, which is remarkable for a legal-tech company that began with a simple experiment in GPT-3.

During an interview on the StrictlyVC Download podcast, CEO Winston Weinberg shared how everything started with a roommate, a landlord-tenant case, and a cold email to Sam Altman. Weinberg and co-founder Gabe Pereyra had been using GPT-3 to test California landlord-tenant questions and found that attorneys approved most of the AI-generated answers without edits. That moment made them realize the legal sector was open for reinvention.

The Breakthrough That Changed Everything

A cold email to OpenAI’s leadership shifted their story almost overnight. Weinberg remembered joining a July 4 call with Sam Altman and the OpenAI leadership team, where they pitched the idea. The OpenAI Startup Fund backed them immediately. From there, investors lined up, even though Weinberg admits he barely understood the venture capital world when they started.

His view on fundraising is simple. Focus on building a company that performs. If the numbers speak for themselves, the right partners follow.

The Challenge Of Global Expansion

Harvey is expanding quickly, especially with corporate clients. At the start of the year, corporates made up four percent of revenue. That number has jumped to thirty-three percent and is still climbing. Much of this growth comes from law firms introducing Harvey to their own clients, turning legal AI into a collaborative tool across teams.

Building this global platform, however, is complex. Each country has strict data processing and residency laws. Setting up compliant infrastructure in regions like Germany and Australia is expensive, and compute costs add up fast. Even so, Weinberg believes these challenges will ease as systems mature.

Why Shared Legal Workflows Matter

Harvey is also working on what Weinberg calls a truly multiplayer platform. Law firms and corporates often work on sensitive matters together, which means permissioning must be flawlessly handled. Ethical walls, confidentiality rules, and cross-team coordination create one of the toughest engineering problems in legal tech. Harvey expects its large-scale version of this system to roll out by December.

How Lawyers Use Harvey Today

Lawyers rely on Harvey for drafting, research, and large-scale document analysis. Litigation use cases are growing fast because they require deep data sets, and Harvey now integrates directly with LexisNexis. The company has also built specialized tools for M&A and fund formation.

Some critics claim Harvey is only a fancy wrapper on top of ChatGPT. Weinberg disagrees. He says the company’s real strength lies in workflow data, evaluation systems, and the multiplayer structure that serves both in-house teams and outside counsel. According to him, no other competitor has managed to bridge both sides of the legal ecosystem at once.

Looking Ahead

Harvey’s vision extends into legal education as well. Weinberg believes AI can help junior lawyers learn faster by acting as a real-time tutor during complex tasks. As for funding, Harvey has no immediate plans for another round. The company prefers staying focused on research, performance, and long-term goals, including an eventual entry into public markets.
