Harvey, a rapidly growing legal AI startup, has completed the acquisition of Hexus, a two-year-old company specializing in tools for product demos, videos, and guides. This move is part of Harvey’s strategy to aggressively expand its operations within the highly competitive legal technology sector. Pratap noted that she will oversee an engineering team dedicated to accelerating the development of Harvey’s solutions for in-house legal departments. “Our contribution to Harvey is extensive experience in building enterprise AI tools for related challenges,” Pratap explained. “This knowledge enables Harvey to advance more quickly in a market that is growing increasingly competitive.”

Prior to the acquisition, Hexus had secured $1.6 million in funding from investors including Pear VC, Liquid 2 Ventures, and several angel investors. Pratap did not disclose the specific terms of the deal but indicated that the arrangement was designed with “long-term team incentives” in mind.

This acquisition occurs as Harvey aims to solidify its status as one of the most prominent startups in the AI landscape. The company confirmed last autumn that its valuation has reached $8 billion following a $160 million funding round, bringing its total funding for 2025 to $760 million. The latest round was led by Andreessen Horowitz, with participation from new investors T. Rowe Price and WndrCo, as well as existing supporters Sequoia Capital, Kleiner Perkins, Conviction, and angel investor Elad Gil. Earlier in the year, Harvey had achieved a $3 billion valuation after Sequoia led a $300 million Series D round.

Harvey now reports serving over 1,000 clients across 60 countries, including a majority of the top 10 U.S. law firms. The company’s origins trace back to when Weinberg, then a first-year associate at O’Melveny & Myers, and co-founder Gabe Pereyra, a researcher with experience at Google DeepMind and Meta who was Weinberg’s roommate at the time, experimented with GPT-3 on landlord-tenant law questions sourced from Reddit. After presenting the AI-generated answers to attorneys, two out of three indicated they would send 86 out of 100 responses without any modifications. “That was the moment we realized this technology could transform the entire industry,” Weinberg recalled. They contacted Altman via email on July 4, 2022, held a call that same morning, and shortly after received their initial investment from the OpenAI Startup Fund. According to Weinberg, the OpenAI Startup Fund continues to be Harvey’s second-largest investor.
