Harvey, a startup building what it describes as a “copilot for lawyers,” today emerged from stealth with $5 million in funding led by the OpenAI Startup Fund, the tranche through which OpenAI and its partners are investing in early-stage AI companies tackling major problems. Also participating in the round was Jeff Dean, the lead of Google AI, Google’s AI research division. and Mixer Labs co-founder Elad Gil among other angel backers.

Harvey was founded by Winston Weinberg, a former securities and antitrust litigator at law firm O’Melveny & Myers, and Gabriel Pereyra, previously a research scientist at DeepMind, Google Brain (another of Google’s AI groups) and Meta AI. Weinberg and Pereyra are roomates — Pereyra showed Weinberg OpenAI’s GPT-3 text-generating system and Weinberg realized that it could be used to improve legal workflows.
