Harvey, the high-flying legal AI startup, has acquired Hexus — a two-year-old startup that makes tools for creating product demos, videos and guides — as the company continues its aggressive expansion amid intense competition in the legal tech market.

Hexus founder and CEO Sakshi Pratap, who previously held engineering roles at Walmart, Oracle and Google, told TechCrunch that his San Francisco-based team has already joined Harvey, while the startup’s India-based engineers will come on board when Harvey sets up a Bangalore office. Pratap added that he will lead an engineering team focused on accelerating offerings for Harvey’s in-house legal department.

“What we bring to Harvey is deep experience in building enterprise AI tools in adjacent problem spaces,” said Pratap. “This expertise helps Harvey move quickly in a market that is becoming increasingly competitive.”

Hexus had raised $1.6 million from peer VC, Liquid2 Ventures and angel investors before the acquisition. While Pratap declined to share the terms of the deal, he said the structure was aligned around “long-term team incentives”.

The acquisition comes as Harvey strengthens its position as one of AI’s hottest startups. The company confirmed last fall that it is now worth it $8 billion After raising $160 million, it brings its funding to $760 million through 2025. Andreessen Horowitz led that new round, joined by new investors T. Rowe Price and WndrCo, existing backers Sequoia Capital, Kleiner Perkins, Conviction and angel investor Elad Gil. (It started the year with a $3 billion valuation After leading a $300 million Series D round at Sequoia Company.).

Harvey now claims more than 1,000 clients in 60 countries, including most of the top 10 US law firms.

When TechCrunch spoke with co-founder and CEO Winston Weinberg in November, he found out about Harvey’s origin story. Cold email Sent to OpenAI CEO Sam Altman. Weinberg, then a first-year associate at O’Melveny & Myers, and co-founder Gabe Pereira, a researcher who worked at Google DeepMind and Meta and was Weinberg’s roommate at the time, tested GPT-3 on a landlord-tenant law question from Reddit. When they showed AI-generated responses to attorneys, two out of three said they would send 86 out of 100 responses with zero edits.

“That was the moment when we were like, wow, this whole industry could be transformed by this technology,” Weinberg said.

They emailed Altman on July 4, 2022, made a call that same morning, and shortly after landed their first check from the OpenAI Startup Fund. OpenAI Startup Fund Harvey is the second largest investor, according to Weinberg.
