Legal AI Giant Harvey Acquires Hexus as Competition Heats Up

Legal AI heavyweight Harvey is continuing its rapid expansion, announcing the acquisition of Hexus, a two-year-old startup known for building tools that help teams create product demos, videos, and guided walkthroughs.

The move comes as competition in legal tech intensifies, with well-funded startups racing to win enterprise and law firm customers. Hexus founder and CEO Sakshi Pratap said her San Francisco based team has already joined Harvey, while the company’s engineers in India will come onboard once Harvey opens a Bangalore office. Pratap will now lead an engineering group focused on accelerating Harvey’s products for in-house legal teams.

“What we’re bringing to Harvey is deep experience building enterprise AI tools in adjacent problem spaces,” Pratap said. “That helps Harvey move faster in a market that’s getting increasingly competitive.”

Before the acquisition, Hexus raised $1.6 million from Pear VC, Liquid 2 Ventures, and a group of angel investors. While deal terms weren’t disclosed, Pratap said the structure was designed around long-term incentives for the team.

The acquisition underscores Harvey’s ambition to cement its position as one of AI’s most valuable startups. Last fall, the company confirmed it had reached an $8 billion valuation following a $160 million raise, bringing its total funding in 2025 to $760 million. The round was led by Andreessen Horowitz, with new participation from T. Rowe Price and WndrCo, alongside existing backers including Sequoia Capital, Kleiner Perkins, Conviction, and angel investor Elad Gil. Harvey began the year valued at $3 billion after Sequoia led a $300 million Series D.

Today, Harvey says it serves more than 1,000 clients across 60 countries, including a majority of the top 10 U.S. law firms.

The company’s origin story has become Silicon Valley lore. Co-founder and CEO Winston Weinberg traces Harvey’s beginnings to a cold email he sent to OpenAI CEO Sam Altman in 2022. At the time, Weinberg was a first-year associate at O’Melveny & Myers. Along with co-founder Gabe Pereyra a former Google DeepMind and Meta researcher and Weinberg’s roommate the pair tested GPT-3 on landlord-tenant law questions pulled from Reddit.

When they showed the AI’s responses to practicing attorneys, two out of three said they would send 86 out of 100 answers to clients without making any edits.

“That was the moment we realized this entire industry could be transformed by this technology,” Weinberg said.

They emailed Altman on July 4, 2022, got on a call the same morning, and soon secured their first investment from the OpenAI Startup Fund which Weinberg says remains Harvey’s second-largest investor today.
