Harvey’s Legal AI Empire Grows with Hexus Acquisition Amid $8B Valuation Surge

Harvey’s $8 billion legal AI empire just got a new weapon: a product demo startup’s engineering team, as the company races to outpace rivals in the AI-powered law firm arms race.

Harvey, a legal AI startup valued at $8 billion, acquired Hexus, a two-year-old product demo tools company, to accelerate expansion in the legal tech market. Hexus CEO Sakshi Pratap said:

"What we’re bringing to Harvey is deep experience building enterprise AI tools in adjacent problem spaces."

Hexus raised $1.6 million from Pear VC, Liquid 2 Ventures, and angels before the acquisition. Deal terms were not disclosed but structured around "long-term team incentives." Harvey raised $160 million in 2025 (total $760 million raised year-to-date) led by Andreessen Horowitz, with OpenAI Startup Fund as its second-largest investor.

Harvey now serves over 1,000 clients across 60 countries, including top U.S. law firms. Its origin story traces to a 2022 cold email to OpenAI CEO Sam Altman demonstrating AI's potential in legal work.
