About

Gabriel Pereyra co-founded Harvey in 2022 with his roommate Winston Weinberg and, as President, supplies the research DNA behind the legal-AI platform valued at $11 billion in March 2026 on roughly $190 million of annual recurring revenue. A machine-learning researcher who published with Geoffrey Hinton at Google Brain, then worked at DeepMind and Meta AI — where he co-authored the OPT-IML instruction-tuned model — he showed Weinberg GPT-3 in their Los Angeles apartment, built a chain-of-thought prompt that answered 100 California tenant-law questions well enough for attorneys to approve 86 of them, and cold-contacted Sam Altman with the results. He now runs Harvey Labs.

Beyond investing

Founded: Co-founded Harvey in summer 2022 with Winston Weinberg, then a securities and antitrust litigator at O'Melveny & Myers; the two were roommates in Los Angeles.
Education: Published machine-learning research with Geoffrey Hinton — a confidence-penalty regularization paper in 2017 and online distillation in 2018.
More: Built an early chain-of-thought GPT-3 prompt for legal questions and cold-contacted Sam Altman and OpenAI's general counsel with the results, which led to the OpenAI Startup Fund seeding Harvey. Their validating test: 100 California tenant-law questions, of which attorneys approved 86 answers. Co-authored OPT-IML, Meta AI's 175-billion-parameter instruction-tuned language model, before leaving to found Harvey. Runs Harvey Labs and argues application-layer companies can reach frontier-grade quality on a small budget through open-weight post-training.
