Harvey, a fast-rising legal AI startup, has acquired Hexus, a two-year-old company that develops tools for creating product demos, videos, and user guides. Through this acquisition, Harvey continues its aggressive expansion strategy as competition intensifies across the legal technology market.
Hexus founder and CEO Sakshi Pratap confirmed that the San Francisco–based team has already joined Harvey. Meanwhile, the company plans to onboard Hexus’s India-based engineers once Harvey establishes its Bangalore office. In addition, Pratap will lead an engineering group focused on accelerating Harvey’s product development for in-house legal teams.
“What we’re bringing to Harvey is deep experience building enterprise AI tools in adjacent problem spaces,” Pratap said. “This expertise helps Harvey move faster in a market that’s becoming increasingly competitive.”
Before the acquisition, Hexus raised $1.6 million from Pear VC, Liquid 2 Ventures, and several angel investors. Although Pratap declined to disclose the financial terms of the deal, she noted that the transaction structure prioritized “long-term team incentives.”
Meanwhile, the acquisition supports Harvey’s broader push to strengthen its position as one of the most closely watched AI startups globally. Last fall, the company confirmed an $8 billion valuation following a $160 million funding round, bringing its total capital raised in 2025 to $760 million. Andreessen Horowitz led the round, with participation from new investors T. Rowe Price and WndrCo, alongside existing backers Sequoia Capital, Kleiner Perkins, Conviction, and angel investor Elad Gil. Earlier in the year, Harvey secured a $3 billion valuation after Sequoia Capital led a $300 million Series D round.
Currently, Harvey serves more than 1,000 clients across 60 countries. Notably, its customer base includes a majority of the top 10 law firms in the United States.
Previously, co-founder and CEO Winston Weinberg traced Harvey’s origins to a cold email sent to OpenAI CEO Sam Altman. At the time, Weinberg worked as a first-year associate at O’Melveny & Myers, while co-founder Gabe Pereyra conducted AI research at Google DeepMind and Meta and shared an apartment with Weinberg. Together, they tested GPT-3 on landlord-tenant law questions sourced from Reddit.
When the founders presented the AI-generated responses to practicing attorneys, two out of three said they would send 86 out of 100 answers without making any edits. “That was the moment when we were like, Wow, this entire industry can be transformed by this technology,” Weinberg said.
The founders emailed Altman on July 4, 2022, secured a call the same morning, and soon received their first investment from the OpenAI Startup Fund. According to Weinberg, the OpenAI Startup Fund continues to rank as Harvey’s second-largest investor.
